Adequate feeding of a horse is essential to help sustain its health and performance in different situations. Traditionally, horses are fed hay or grazed grass without or with grains plus supplements or compound feeds. However, the practice of feeding horses varies greatly in the UK depending upon the workload of a horse, co-location of the owner and the seasonal variations mainly due to the weather and the availability of pasture or hay. Although many complete feeds are also available commercially, their nutritive values do vary and thus they may not suit a horse. Therefore, there is a need to formulate nutritious diets that are palatable for a horse and cost-effective for the owner. It is also imperative to prepare diets that are more completely digested to minimise faecal contamination the environment. This study compared the suitability of three coarsely mixed diets to improve digestion and reduce excretion in adult ponies.
