ABSTRACT
Omidi
A, Seyrafinia M., Stepwise formulation based on body weight, intake, maintenance, protein
and energy and forage/concentrate for
horses, Onl J Vet Res., 27 (4): 233-237,
2023. We describe a stepwise formulation for adult horses based on body weight, dry matter
intake, maintenance, protein, energy and forage/concentrate
to satisfy National Research Council (NRC 2021) nutrient requirements for
working and pregnant horses. Body weight was determined by weighbridge, height,
girth and body length, dry matter as feed ingested % of weight for maintenance,
energy as 2.5% + 4, crude protein in g/kg dry matter (%). For
forage/concentrate ratio 1% of body weight forage daily, for maintenance 100% of diet but for working
horses, stallions in breeding season, pregnant mares, and lactating mares at
least 50% forage whereas intense work requires ~65% concentrate.
Key Words: Stepwise formula, requirements, working, stallion, pregnant
mares.
