A summary of the principles behind the growth and development of the equine from birth until maturity is undertaken. Examination of the processes of musculoskeletal, circulatory, neurological and endocrinological development will be undertaken. Aspect of nutritional demand and change will be explained. An understanding of the changes in physiological demand and the related problems these may cause is covered. This will enable an understanding of developmental aliments and diseases, their likely cause, treatment, prognosis and prevention in the developing equine. Examination of correct equine structure and static conformation in relation to needs and demands both developmentally and at maturity is demonstrated. Initial Investigation into dynamic movement and related biomechanical factors is undertaken.Three Stars
