Study on Effect of Feeding Deoiled Sal Seed Meal (DSSM) at Different Levels to Kankrej Cows on Milk Yield and Composition

Abstract

An experiment was conducted for 300 days of lactation to study the effect of feeding deoiled sal seed meal (DSSM) at 0, 10 and 20% levels in concentrate mixtures on milk yield, fat-corrected milk (FCM) yield and milk composition of Kankrej cows. The results revealed a significant reduction in both milk and FCM yields in the treatment receiving 20% DSSM, indicating that incorporation of DSSM at this level adversely affected milk production compared with the control treatment. The treatment containing 10% DSSM showed the best performance among the three treatments. Thus, DSSM should not be included at more than 10% in the concentrate mixture of lactating animals. Milk composition was slightly lower for some constituents in the group receiving 10% DSSM; however, the differences among the three treatments for all analysed milk constituents were statistically non-significant.
