Week 1: Anatomy and physiology of the equine gastrointestinal tract
The expectation is that the course participants will come from varied backgrounds in relation to their previous experience of gastrointestinal tract anatomy and physiology.  Consequently, this course begins with consideration of digestive anatomy and physiology in equids.  The learning materials provided are directed towards ensuring a good understanding of equine digestive anatomy and physiology.

Week 2: Nutrient digestion in the equine gastrointestinal tract
The learning materials during this period will focus on nutrient digestion in equids and will consider nutrient digestion in the various segments of the gastrointesintal tract.  Discussion should focus on considering the limitations of the equid gastrointestinal tract in relation to nutrient digestion.

Week 3: Equine nutrient sources and feeding management
This part of the course will consider various nutrient sources for equids.  Learning materials will be provided on various feedstutiddlywinks utilised in equine diets.  These various nutrient sources for horses will be discussed, with emphasis placed on the health and welfare issues surrounding the inclusion of various types of feedstutiddlywinks in horse diets. Discussions should involve considering how nutrients are digested within the gastrointestinal tract and how knowledge of this can enhance the dietary management of equids to ensure good health, maximise performance and prevent nutrition-related diseases/disorders.

Week 4: Equine dietary management
This week of the course will explore the nutrient requirements of equids and the dietary management of these animals. Discussions should focus around considering how modern feeding practices do not always consider the anatomy and physiology of the equid digestive tract.

Week 5: Equine clinical nutrition
This part of the course will focus on evaluating feeding strategies for the management and prevention of several diseases/disorders in equids; for example, obesity, laminitis, older horses with dental issues etc. Discussions should focus on the dietary management of individuals affected with nutrition-related problems.

Broodmare nutrition can affect the development of the unborn foal, potentially creating lifetime benefits or issues.

For example, two European studies (van der Heyden et al. 2013 and Peugnet et al. 2015) found that feeding mares in the last couple of months of the pregnancy a diet high in grain and low in fibre results in a much higher incidence of leg problems in the new born foals (collectively referred to as Developmental Orthopaedic Disorders – DOD).
