Abstract

Marwari stallions (5–6 year age and 345 kg BW) were fed on a sole diet of sewan grass (Lasiurus sindicus) hay in order to define its nutritive value for horses. The grass contained 2.45% DCP, 57.47% TDN, 1:22.46 nutritive ratio and 52.31% starch equivalent. The daily dry matter intake was recorded to be 2.77 kg/100 kg BW equivalent to 119.80 g/kg W0.75 indicative of its high palatability in horses. The average digestibility coefficients were found to be 52.39, 55.75, 45.46, 47.04, 67.35, 39.70, 30.66, 49.48 and 47.91 for DM, CP, CF, EE, NFE, NDF, ADF, hemicellulose and cellulose, respectively. Theintake of digestible nutrients i.e. DCP (236 g/d) and DE (24.43 Mcal/d) revealed that a sole feeding of the hay is adequate to meet the maintenance requirements of mature horses at rest. It was observed from the study that horses can efficiently utilize sewan grass hay and it can serve as basal roughage source for horses in arid regions of country.
