Possible diet structure alternatives to the traditional diet

Supplementing high-fibre forage diets with concentrated grain feed is common for meeting energy needs, such as sport horses and lactating mares. This study suggests replacing the traditional diet supplying forage and concentrate separately for a thermally processed complete feed supplying both combined. And assesses nutrient digestibility and fermentative effects in 8 ponies via faecal and blood analysis, through 4 cycles of 20 days, including adaptation and collection periods. Both, traditional and the complete diets, pelletized and extruded, provided equal isoprotein portions with 1.75 BW daily dry matter intake.

In conclusion, no gastrointestinal or clinical problems were observed during this short-term study and complete diets might simplify feeding management. However, their safety and effects on digestion, feeding behaviour, microbial fermentation and intestinal health are still not clear enough. Therefor more studies and information is needed.

Expert opinion by Shirley Ferber

The complete diet effects on digestion, feeding behaviour, microbial fermentation and intestinal health are not clear and require further research. Traditionally separated diets seem like the safer, more flexible, choice to ensure safe sugar and starch concentrations while meeting fibre and energetic needs.
