ASC210 Equine Reproduction (8)

This subject builds on content studied in biology and provides the opportunity to study the functional anatomy and physiology of the equine reproductive systems. Topics covered include anatomy of the mare and stallion reproductive tract, endocrine control of reproduction, seasonality, mare oestrous cycles, gametogenesis, physiology of the equine pregnancy and parturition, as well as basic genetic inheritance. On successfully completing this subject students will possess an understanding of the science behind the management decisions required when breeding horses and raising foals.

Learning Outcomes

Upon successful completion of this subject, students should:
  • be able to identify and describe the reproductive anatomy of the mare and stallion and discuss its function;
  • be able to describe the endocrine mechanisms that regulate equine reproduction and explain the physiological and behavioural changes that occur during the oestrous cycle and with changing seasons;
  • be able to describe the processes of gametogenesis and fertilisation in the horse;
  • be able to list and explain the major events of foetal development, placentation and parturition in the horse;
  • be able to explain the basic mechanisms of inheritance; and
  • be able to describe common genetic disorders of horses and carry out basic calculations to predict the possible outcomes for coat colour and genetic disorders for given examples.


This subject will cover the following topics:
  • The structure and function of the male and female equine reproductive systems.
  • Endocrine control of reproduction in the stallion.
  • Endocrine, physiological and behavioural events of the oestrus cycle in the mare.
  • Factors affecting puberty, anoestrus and seasonality in the equine.
  • Gametogenesis in the male and female horse.
  • Sperm production and output, parameters of the equine semen.
  • Process of gamete transportation and fertilisation.
  • Maternal recognition of pregnancy, placentation and foetal development, parturition and lactation in the mare.
  • Basic mechanisms of inheritance including structure, role and behaviour of chromosomes and genes, mendelian inheritance, common phenotypes that are determined or influenced by one or a few genes in horses, including coat colour and disorders with a genetic basis.

Indicative Assessment

Residential School

This subject contains a 3 day Compulsory Residential School.

The Residential School for this subject will allow students who are studying online to both directly experience and implement aspects of equine reproduction.  This will allow students to put the theory gained online into practice under industry conditions.  The three day residential school will comprise a mixture of workshops, yard/stable/paddock and laboratory based activities that will complement the theoretical materials delivered on line throughout this subject. Such practical experiences will include reproductive anatomy of the stallion and the mare, dissection of pregnant reproductive tracts, semen evaluation, identification of ova and scanning mares using ultrasound.

Special Resources
