"Repeat matings of a pairing that has proven successful seems like mere common sense. The 17th Earl of Derby, one of the most influential breeders of all time, not only followed up proven matings in this fashion but advocated the position that if one believed in a mating enough to try it at all, one should repeat it twice more before moving on. On the other hand, some breeders voice a fear of “going to the well too often” and are reluctant to repeat a mating more than once.

Which is the better strategy for producing good runners?

Average Earnings Index (AEI) for Stallions

Understanding High, Medium, and Low AEI

The Average Earnings Index (AEI) is a significant metric used in the equestrian world to evaluate the financial performance of stallions based on their offspring's earnings in competitions. This index helps breeders and buyers to make informed decisions about the potential value and profitability of a stallion's progeny. The AEI is categorized into three levels: high, medium, and low, each reflecting different degrees of earnings and success.

High Average Earnings Index (High AEI)

Stallions with a high AEI are those whose offspring consistently earn substantial amounts of prize money in various competitions. The specific figure that constitutes a high AEI can vary depending on the competitive landscape and economic conditions. However, a stallion with an AEI of 2.00 and above is generally regarded as having a high AEI. These stallions are often sought after for breeding because their progeny have a proven track record of success, indicating genetic superiority and potential for high returns on investment.

Medium Average Earnings Index (Medium AEI)

A medium AEI represents a stallion whose offspring earn moderate amounts of prize money. Stallions with an AEI ranging from 1.00 to 1.99 are typically considered to have a medium AEI. This group is valuable to breeders who are looking for stallions that can produce competitive offspring without the premium cost associated with high AEI stallions. Medium AEI stallions offer a balance between performance and affordability, making them accessible options for many breeders.

Low Average Earnings Index (Low AEI)

Stallions with a low AEI are those whose offspring earn below average amounts of prize money in competitions. An AEI below 1.00 is usually classified as low. These stallions might be less desirable for competitive breeding purposes but can still have a place in the market for niche breeding programs or for those prioritizing other traits such as temperament, conformation, or specific genetic characteristics. Breeders may opt for low AEI stallions if they are working within a limited budget or focusing on non-competitive aspects of breeding.

Factors Influencing AEI

Several factors impact a stallion's AEI, including:

·         Genetic Quality: The inherent genetic traits passed on to offspring play a crucial role in determining their competitive success and earnings.

·         Training and Management: The quality of training and management of the offspring can significantly affect their performance and earnings.

·         Competition Level: The level and frequency of competitions in which the offspring participate influence their earnings and, consequently, the stallion's AEI.

·         Market Conditions: Economic factors and prize money distribution in the equestrian industry can affect the earnings of offspring.

Conclusion

Understanding the Average Earnings Index (AEI) is essential for anyone involved in the equestrian breeding industry. It provides a straightforward measure of a stallion's financial impact through its progeny, helping breeders and buyers make informed decisions. Whether opting for high, medium, or low AEI stallions, it is crucial to consider the various factors that influence these indices and align breeding choices with specific goals and resources.

Implementing Desired Genetic Influences in a Horse's Pedigree

Breeding Techniques and Genetic Management

Introduction

Breeding horses for specific traits has been a practice for centuries, with the goal of enhancing desirable characteristics such as speed, endurance, temperament, and physical appearance. The modern approach to horse breeding combines traditional methods with advanced genetic management techniques to "switch" on or implement desired genetic influences in a horse's pedigree.

Understanding Genetic Influences

Genetic influences refer to the inherited traits passed down from parent to offspring through genes. These traits can be physical, behavioural, or even health-related. In horses, genetics play a crucial role in determining qualities such as coat color, height, muscle structure, and predisposition to certain diseases.

Selective Breeding

Selective breeding is the most traditional method of influencing a horse's genetic makeup. By carefully choosing parent horses that exhibit desired traits, breeders can increase the likelihood that these traits will be passed on to the next generation. This method relies on understanding the genetic history of both the mare and the stallion and predicting the potential outcomes of their offspring.

Line Breeding and Inbreeding

Line breeding involves mating horses that are closely related but not directly inbred, aiming to consolidate desirable traits within a specific lineage. Inbreeding, on the other hand, involves mating closely related horses to intensify specific genetic qualities. While effective in enhancing certain traits, inbreeding carries the risk of increasing the prevalence of undesirable recessive genes, leading to potential health issues. The ideal method to use in Linebreeding, is to identify from the Pedigree, what Archetypes are most advantageous, and search for sires containing those desired to linebreed to

Crossbreeding

Crossbreeding, or outcrossing, involves mating horses from different breeds or bloodlines to introduce new genetic material and enhance specific traits. This method can improve genetic diversity, reduce the risk of inherited disorders, and combine the strengths of both parent breeds. However, it requires careful selection to ensure that the desired traits are not compromised.

Genetic Management Techniques

Advancements in genetic science have introduced new methods for managing and implementing desired genetic influences in horse breeding.

Genetic Testing

Genetic testing allows breeders to analyse the DNA of horses to identify specific genes associated with desired traits. By understanding the genetic makeup of potential parent horses, breeders can make informed decisions about mating pairs to enhance the likelihood of passing on desirable characteristics. Genetic tests can also identify carriers of hereditary diseases, enabling breeders to avoid mating pairs that could produce affected offspring.

Marker-Assisted Selection

Marker-assisted selection (MAS) is a technique that uses genetic markers to select horses with specific desirable traits. These markers are associated with genes that influence traits such as speed, agility, or coat color. By selecting horses with the appropriate markers, breeders can implement desired genetic influences more efficiently.

Genome Editing

Genome editing technologies, such as CRISPR, offer the potential to directly modify the DNA of horses to enhance specific traits. While still in the experimental stages for equine breeding, this method could revolutionize how genetic influences are implemented by allowing precise alterations to the genetic code. Ethical considerations and regulatory challenges must be addressed before genome editing becomes a standard practice.

Pedigree Analysis and Management

Managing a horse's pedigree involves tracking and analyzing the genetic history of breeding lines to ensure the implementation of desired genetic influences.

Pedigree Charting

Pedigree charting visually represents the lineage of a horse, highlighting the genetic connections between ancestors and offspring. By examining these charts, breeders can identify patterns and trends in the inheritance of traits, helping to make informed decisions about future breeding pairs.

Coefficient of Inbreeding

The coefficient of inbreeding (COI) measures the degree of relatedness between mating horses. A low COI indicates minimal inbreeding, while a high COI suggests closer genetic relationships. Managing COI is crucial to balancing the implementation of desired traits with maintaining genetic diversity and minimizing health risks. Around 5% coeff (Wrights) is considered to be the cutoff, and inbreeding with a higher % should be treated with caution to ensure that plans do not go awry, for the sake of marketability or fashion.

Performance Record Analysis

Analyzing the performance records of horses within a pedigree can provide insights into the effectiveness of breeding strategies. Traits such as racing speed, endurance, and temperament can be evaluated to determine the success of genetic management techniques.

Conclusion

Implementing desired genetic influences in a horse's pedigree involves a combination of selective breeding, genetic management techniques, and careful pedigree analysis. By leveraging advancements in genetic science and maintaining ethical breeding practices, breeders can enhance the quality and performance of their horses while ensuring the health and diversity of future generations.

The integration of traditional methods with modern genetic technologies offers exciting possibilities for the future of equine breeding. As breeders continue to refine their techniques and expand their understanding of genetics, the ability to "switch" on desired genetic influences will become increasingly precise and impactful, leading to the development of superior horses that excel in their respective disciplines.

Utilisation of the Genetic Weighting Formula

An example of its application for racehorses

The Genetic Weighting Formula is a tool used to estimate the genetic potential of racehorses based on the abilities of their sire and female ancestors. The formula is represented as follows:

GP = (Sire_ability × 0.5) + (Female_ability × 0.5)

To provide a practical example, let us consider two racehorses: Thunderbolt and Lightning Flash. Thunderbolt is the sire and Lightning Flash is the dam. We need to evaluate their abilities to predict the genetic potential of their offspring, Storm Runner.

Step-by-Step Calculation

Determining the Sire's Ability

The sire of Storm Runner is Thunderbolt. In this example, Thunderbolt’s racing ability has been quantified based on past performances, speed, and endurance. Let’s assign Thunderbolt a racing ability score of 85.

Determining the Female's Ability

The dam of Storm Runner is Lightning Flash. Similarly, we evaluate Lightning Flash’s racing ability by considering her past performances, speed, and endurance. Let’s assign Lightning Flash a racing ability score of 80.

Applying the Formula

Using the Genetic Weighting Formula, we can calculate Storm Runner’s genetic potential as follows:

·         Sire_ability (Thunderbolt): 85

·         Female_ability (Lightning Flash): 80

·         GP = (85 × 0.5) + (80 × 0.5)

·         GP = 42.5 + 40

·         GP = 82.5

Therefore, based on the Genetic Weighting Formula, Storm Runner’s genetic potential is estimated to be 82.5.

Implications of the Genetic Weighting Formula

The Genetic Weighting Formula provides a simplified yet effective method to gauge the potential performance of racehorse offspring. By using this formula, breeders and trainers can make informed decisions on pairing racehorses to enhance the likelihood of producing high-performing progeny.

Factors Influencing Genetic Potential

It is important to note that while the Genetic Weighting Formula offers valuable insights, it is not an absolute predictor of a racehorse’s future performance. Several factors can influence the genetic potential, including:

·         Training and conditioning

·         Diet and nutrition

·         Environmental factors

·         Inherent health and physical attributes

Additionally, genetics can sometimes produce unexpected outcomes, as the combination of genes from the sire and dam can interact in complex ways. Thus, the Genetic Weighting Formula should be used as one of several tools to evaluate and develop racehorse potential.

Conclusion

The Genetic Weighting Formula offers a structured approach to estimate the genetic potential of racehorses. By analyzing the abilities of both sire and female ancestors, breeders can make strategic decisions to optimize breeding practices. However, it remains essential to consider other factors such as training, nutrition, and overall care to achieve the best possible outcomes for racehorse development.

Using the formula:

GP = (Sire_ability × 0.5) + (Female_ability × 0.5)

we have demonstrated how Thunderbolt and Lightning Flash’s abilities translate into the genetic potential of their offspring, Storm Runner. While Storm Runner’s genetic potential score of 82.5 is promising, the true test will be in its development, training, and performance on the racetrack.

Inbreeding Recommendations for Thoroughbreds

Expert Opinions and Guidelines

JJ Vuillier, the principal bloodstock advisor to the Aga Khan III, along with his wife, Mme Germaine Vuillier, have been long-time proponents of carefully regulated inbreeding practices within the Thoroughbred community. Their expert opinion, grounded in years of experience and extensive research, highlights key recommendations aimed at preserving the health and genetic diversity of Thoroughbreds.

Guidelines for Inbreeding

The Vuilliers advised strongly against inbreeding closer than the fifth generation. This recommendation is based on their thorough understanding of the potential complications that can arise from close genetic relationships. They assert that inbreeding within closer generations can lead to an array of genetic disorders and health issues, thus should be generally avoided to maintain the vitality of the Thoroughbred lineage.

Exceptions to the Rule

Despite their cautious stance on inbreeding, the Vuilliers have identified a notable exception. Inbreeding involving siblings, particularly full brothers, does not carry the same level of risk as other close genetic pairings. Under certain specific circumstances, this form of inbreeding may be considered. Their belief is that such exceptions, if managed carefully, can be beneficial without introducing significant genetic risks. They did however make a case for inbreeding from one ancestor in the 3^rd/ 4^th remove back to other ancestors in the 5th remove and beyond, subject to certain criteria being met, and as evidenced by Ezelia, (see further reference)

As an example, Zahra (filly named after Aga Khan IV's daughter) pedigree has many inbreeding’s from the 5th remove backwards:

Plucky Liege (1912) - F - 16-a 5m, 6m x 4m

Teddy (1913) - M - 2-n 5m, 7f x 2 0

Swynford (1907) - M - 1-g 5m, 7f x 6m

Phalaris (1913) - M - 1-i 7m, 7m x 5m 3

Scapa Flow (1914) - F - 13-e 7m, 7m x 5m

Lady Josephine (1912) - F - 9-c 8f x 5f, 6f

Gainsborough (1915) - M - 2-n 7m x 5m, 5f

Spearmint (1903) - M - 1-c 6f, 7f, 8f x 5f

Concertina (1896) - F - 16-a 6f, 7f x 5f, 7f

Blandford (1919) - M - 3-o 8m x 5m.

The many inbreeding’s from the 6th remove and beyond are omitted.

In later years, it seems with the emergence of Princess Zahra Aga Khan, who undertook much of the hands on management from her Father, there has been a more relaxed approach to the question of inbreeding. This shift is evident in the pedigree of English Oaks Heroine, Ezelia, which shows multiple instances of inbreeding from the fourth remove back, many involving females.(however the Wright’s coeficient on inbreeding is only 2.77%, well inside the recommended 5% cutoff) This trend reflects a nuanced understanding of genetic principles and a willingness to balance tradition with modern scientific insights. The message being, one needs to be adaptable to change in philosophy, recognising that because of the number of thoroughbreds worldwide now, the shrinking of the genetic pool, is somewhat diluted because of the somewhat separate populations in USA, South America Europe and Australia and New Zealand, thereby enabling access to diversity

Emphasis on Genetic Diversity

The cornerstone of the Vuilliers' guidance is the emphasis on maintaining genetic diversity within the Thoroughbred breeding program. By avoiding close inbreeding and encouraging a broader genetic pool, breeders can ensure the health, endurance, and overall vitality of future generations of Thoroughbreds. Genetic diversity is crucial for the long-term sustainability and success of these esteemed horses, protecting them from inherited disorders and enhancing their adaptability.

In conclusion, the recommendations provided by JJ and Mme Germaine Vuillier serve as a vital framework for Thoroughbred breeders, balancing the risks and benefits of inbreeding practices. Their advice underscores the importance of strategic breeding decisions, aimed at preserving the integrity and excellence of the Thoroughbred lineage for generations to come.

Determining the Best Mares to Source for Breeding Successful Racehorses

Guidelines and Practical Strategies

The importance of the female in determining the abilities of the sire has long been acknowledged in the world of horse breeding. As Mme Vuillier wisely stated, “it’s the Mare who makes the Stallion and not the reverse.” A successful stallion, paired with the right mare, significantly enhances the chances of producing a successful racehorse. But how can this be practically achieved? What are the best ways of determining the type of mares to source? Below, we explore various types and qualities of mares that should be considered to maximize the potential of breeding superior runners.

Types and Qualities of Mares to Source

Raced Mares

·         Performance Record: Mares that have demonstrated outstanding performance on the track are valuable. Their racing history can give insights into their speed, stamina, and competitive spirit.

·         Injury History: Evaluate their health and injury records to ensure they are capable of producing sound offspring.

Black Type winning  Mares

·         Proven Success: Black type winners, those who have won or placed in stakes races, have proven their quality on the track. These mares are highly sought after for their demonstrated capability to compete at the highest levels.

·         Genetic Influence: Their genetic traits can greatly influence the performance of their offspring, making them a valuable addition to a breeding program.

Successful Producers

·         Track Record of Offspring: Mares that have already produced successful racehorses offer a reliable indication of their breeding potential. Their offspring’s performance speaks volumes about their genetic contribution.

·         Consistency: Look for mares that consistently produce high-quality runners, indicating strong and reliable genetics.

Producers of Superior Runners

·         High-Performing Progeny: Mares whose offspring have excelled on the track, particularly in top-tier races, are extremely valuable. Their ability to pass on superior traits is confirmed by the success of their progeny.

·         Legacy: These mares often become the cornerstone of breeding programs, contributing significantly to the legacy and success of future generations.

Unraced Mares

·         Pedigree: While they may not have a racing record, their lineage can provide clues to their potential. Look for mares with ancestors who were successful racehorses.

·         Conformation: Physical attributes such as build, strength, and gait should be carefully assessed to ensure they possess qualities conducive to breeding strong racehorses.

Unraced Mares with Strong Pedigree

Potential Unseen: Unraced mares, though they lack a track record, can still offer immense value to a breeding program. Their potential lies in their pedigree, which can be rich with high-performing ancestors.

Genetic Lottery: Breeding with unraced mares is akin to playing a genetic lottery, where the rewards can be substantial if the mare's lineage is strong. Such mares often carry the latent potential of their illustrious forebears.

Mares with Exceptional Pedigree

Lineage Matters: The pedigree of a mare is a crucial factor in breeding decisions. Mares hailing from families with a history of producing champions are highly prized.

Ancestral Excellence: The influence of renowned sires and dams in the pedigree can significantly enhance the chances of producing superior offspring, making such mares a strategic choice for any breeding program.

Mares with Potential for Improvement

Untapped Talent: Some mares, whether raced or unraced, may show potential for improvement in their offspring. These mares may not have had stellar careers themselves but possess genetic traits that can benefit their foals.

Breeding Strategy: By pairing these mares with top-quality stallions, breeders can unlock the hidden potential in their genetics, leading to the production of high-caliber racehorses.

Optimum Age for Broodmares

Prime Years: The age of a broodmare is a critical aspect to consider in breeding programs. Most breeding experts agree that the optimum age range for broodmares to produce superior racehorses is between 4 to 12 years. During these prime years, mares are typically at the peak of their reproductive health and can pass on their genetic strengths most effectively.

Balancing Act: While younger mares might have fresher genetics, older mares bring the advantage of proven fertility and foaling records. Striking a balance by maintaining a broodmare band within this age range can significantly elevate the chances of breeding outstanding racehorses.

Significance of Foaling Numbers

First Foals: The order in which a broodmare produces her foals can also impact the quality of her offspring. Many breeders believe that first second to sixth foals often carry a unique vigour and potential, (First foals are often “behind the eight ball in size at birth due to the confined spaces in maiden mare s uterus etc, ) attributable to the mare's fresh genetic material and optimal reproductive health during her early breeding years.

Later Foals: Conversely, foals born later in a mare's breeding career can benefit from the mare's maturity and proven fertility. These foals may inherit advantageous traits honed through the mare's previous breeding experiences, potentially leading to enhanced performance on the racetrack.

Optimal Strategy: It is important for breeders to carefully monitor the performance of a mare's foals over time, adjusting breeding strategies to maximize the genetic potential of both first and later foals. By balancing the production of foals across a mare's prime years, breeders can effectively harness the strengths of each foal, increasing the likelihood of producing superior runners.

Conclusion

In conclusion, sourcing the right mares for a breeding program is pivotal in enhancing the chances of producing successful racehorses. Whether they are raced, unraced, black type winners, successful producers, or producers of superior runners, each type of mare brings unique qualities to the table. By carefully evaluating their performance, pedigree, conformation, and track record of offspring, breeders can make informed decisions that will ultimately lead to greater success on the racetrack.

Building Excellence Through Commitment and Care

The preparation of racehorses is an intricate process that requires unwavering patience and an investment of time to develop these majestic animals into champions. Unlike other sports where talent and skill can be honed quickly, equestrian racing demands a methodical approach, where the physical and mental growth of the horse is nurtured with care and precision. Patience and time serve as the foundation for success in this competitive realm, balancing the need for discipline and training with the respect for the horse’s natural development.

The Role of Patience in Racehorse Training

Patience is the cornerstone of racehorse training. It involves understanding the unique nature of each horse, accommodating its quirks and temperament, and allowing it to progress at its own pace. Horses, much like humans, have individual personalities, and imposing a rigid training schedule without regard for their individuality can lead to not only diminished performance but also injury or psychological stress.

Developing Trust and Communication

The bond between a trainer and a racehorse is built on trust. This trust cannot be rushed; it evolves over time as the horse becomes familiar with the trainer’s voice, touch, and commands. A patient trainer invests time in building this rapport, ensuring the horse feels safe and secure in their presence. Trust is vital for the horse to respond effectively in high-pressure situations, such as in the starting gate or during a race.

Physical Conditioning with Care

Racehorses require rigorous physical conditioning, but this must be done progressively. A patient approach recognizes the importance of respecting the horse’s physical limits, gradually increasing workload to build endurance, speed, and strength. Overtraining can lead to fatigue and injuries that may jeopardize the horse’s career. Patience ensures that the horse’s health remains paramount throughout its preparation.

The Significance of Time

Time is an equally critical factor in racehorse preparation. Unlike machinery that can be fine-tuned in a matter of hours, the development of a racehorse spans months, even years. From a foal to the peak of their racing career, racehorses undergo a series of developmental stages that cannot be expedited without risking adverse outcomes.

The Natural Growth Process

A horse’s musculoskeletal system requires sufficient time to mature before it can endure the demands of racing. Training a horse too early can lead to long-term health issues, undermining its potential for a successful career. Trainers must respect the natural timeline of growth, allowing young horses to develop strength and resilience.

Skill Acquisition and Refinement

Racehorses are not born knowing how to race; they must acquire and refine skills such as starting from the gate, pacing, and responding to jockey commands. This learning process takes time and repetition. Forcing a horse to adopt these skills quickly can result in confusion and resistance, whereas a gradual teaching approach ensures mastery and confidence.

Long-Term Success Over Short-Term Gains

In the world of competitive racing, the temptation to push for immediate results is ever-present. However, trainers who prioritize time and patience often produce horses that enjoy longer, more successful careers. By investing in the horse’s comprehensive development, rather than rushing to meet short-term goals, they lay the groundwork for sustainable achievement.

Balancing Patience and Time in Racehorse Preparation

While patience and time are individually significant, their true power lies in their synergy. It is one thing to wait for a horse to develop, but it is another to actively use the time to implement thoughtful strategies that maximize its potential. Trainers must strike a delicate balance between allowing a horse to progress naturally and ensuring that the time invested is productive.

Setting Realistic Goals

Realistic goals are essential to maintaining a balance between patience and time. Trainers must acknowledge the individual capabilities of each horse and tailor training programs accordingly. This not only prevents frustration and setbacks but also builds confidence in the horse as it achieves milestones.

Monitoring Progress

Throughout the preparation process, trainers must diligently monitor the horse’s progress. This involves assessing physical conditioning, behavioral changes, and skill acquisition. By tracking development, trainers can adjust their approach to ensure the horse is moving steadily towards readiness.

Maintaining Discipline

While patience involves flexibility, it also requires discipline. Trainers must remain committed to the long-term vision, resisting the urge to abandon careful preparation for quicker results. Discipline ensures that the time spent on training is meaningful and aligned with the horse’s best interests.

Examples from Champion Racehorses

The importance of patience and time is exemplified by the stories of legendary racehorses. Legends like Secretariat, Sea Biscuit, and Frankel were not overnight successes; their greatness was cultivated through years of dedicated training and care. These champions serve as reminders that excellence in horse racing is achieved through persistence, commitment, and an understanding of the value of time. The great Australian racehorse “

Conclusion

Patience and time are indispensable in the preparation of racehorses. They form the backbone of a training philosophy that prioritizes the well-being and natural development of the horse while paving the way for competitive success. Trainers who embrace these principles not only enhance the horse’s performance but also contribute to its longevity and overall happiness. In the art and science of racehorse preparation, patience and time are not merely virtues—they are necessities that ensure the triumph of both horse and trainer.” PATIENCE is a virtue, possess it if you can. Seldom in a woman, never in a man." Bart Cummings, and “"Patience is the cheapest thing in racing but most people don't use it,"

A couple of months ago Byron Rogers of Performance Genetics forwarded a link to a recently published study on population genetics. A team of researchers in China and Australia generated statistics that suggest a mother’s influence may actually be more important than a father’s influence when it comes to racing ability. Is this study a fluke of statistical analysis or is there solid science behind it?

In the paper “Potential role of maternal lineage in the Thoroughbred breeding strategy,” published in Reproduction, Fertility and Development in May 2015, by Xiang Lin, et al., the racing ability of 675 Australian Thoroughbreds was categorized by average earnings per start as an indicator of quality of performance and ranked from highest to lowest. The top 30% of earners were put into the “Elite” group of performers and the remaining 70% into the “Poor” group. 

The runners were divided into four groups based on their parentage: Elite dam vs. Elite sire (EE), Elite dam vs. Poor sire (EP), Poor dam vs. Elite sire (PE), and Poor dam vs. Poor sire (PP).

The results indicated the best runners were from the EE group (Elite dam and sire), while the worst were from the PE group (Poor dam, Elite sire). Surprisingly, the PP group (Poor dam and sire) was not the worst, as one would expect.

https://www.bloodhorse.com/daily" rel="nofollow - SIGN UP FOR Here’s the interesting part: Foals with Elite dams (EE and EP) had statistically similar superior results while foals with Elite sires (EE and PE) did not demonstrate the same similarities, instead, showing an influence related more closely to the performance of their dam. The foals of Poor dams (PE and PP) were poor across the board, even those by Elite sires.

The study concludes “that maternal heritability of athletic performance may be a stronger contributor than paternal heritability to race ability.”

The researchers hypothesize that this is due to mitochondrial DNA (mtDNA), which is inherited only through the female parent and has a strong influence in the production of ATP, the prime source of energy for any activity, in particular, physical exercise. Sires pass on a lot of important characteristics to their progeny, but they don’t pass on mtDNA as mares do. If superior mtDNA is the thing that makes the critical difference, then we’ve been putting emphasis in the wrong place, relying too heavily on stallions.

Since Joe Estes’ research in the 1940s and 1950s, studies have proved time and again that the best racemares make the best broodmares, but up until now it hasn’t been demonstrated that the mare’s input may actually be more important than that of the sire’s. Good racemares are almost always bred to the best stallions available, so testing them against members of the “poor” community hasn’t been something that most breeders would attempt, which makes these results especially intriguing.

Theories have tried to prove the greater importance of good mares with mixed success. Geneticists have already discounted the so-called “X Factor” theory, which proposed that weaving their way down the breed were certain x-chromosomes that were deemed responsible for producing larger-than-average hearts, which, in turn, were presumed to translate into greatness. While several genes are related to heart size, researchers mapping the equine genome didn’t find any of them on the x-chromosome. This doesn’t dismiss the idea that certain females could pass on certain superior traits, only that the X Factor, as it relates to heart size, wasn’t on the x-chromosome.

The so-called “Rasmussen Factor” is a theory focused on inbreeding to superior females. Inbreeding to any superior individual sounds like a good idea, but often the parents are simply not good enough to pull it off or the key ancestors are so distant that their influence is too diluted to be effective. There are many clever examples of the Rasmussen Factor, but it hasn’t proved itself under statistical scrutiny.

Bruce Lowe’s numbered female families are based on the direct tail-female path of the mtDNA, and his Family 1 remains the most prominent in producing top runners, for some reason, even today. Is it due to mtDNA? Some of his ideas seemed far-fetched, but maybe not so much now.

This new study on maternal influence could help explain why so few stallions succeed in the highly competitive stallion market, or, rather, why so many apparently well-qualified stallion prospects prove mediocre or fail altogether.

It could also help us understand why the stallions we have valued as good or great can sire stakes winners at a rate as low as 5% of their foals, or a few rare ones, such as Danzig, as high as 19%. Compare this to a remarkable broodmare such as Juddmonte Farms’ Hasili, who produced 70% stakes winners to foals.
