Effect of composite feed additive on milk urea concentration and protein degradation in vivo in lactating buffaloes

The study was conducted to examine the effect of composite feed additive on milk urea (MU) concentration the lactating buffaloes. A total of 18 Murrah lactating buffaloes (Bubalus bubalis) (avg. milk yield 10.83± 1.56 kg) and (avg. live weight, 507.24 ± 44.18 kg; parity, 2-5) at early stage (30 days) of lactation were selected and divided into two groups of 8 animals each using a completely randomized block design. They were allocated into two dietary groups, control and treatment containing basal feed without or with composite feed additives, respectively. Composite feed additive (CFA) was fed @ 2.5% of total dry matter intake in the treatment group along with concentrate mixture. The urea conc. (mg dl-1) in milk of experimental buffaloes at weekly interval was recorded. Initial milk urea (MU) concentration was comparable (p>0.05) between the groups. The concentration of MU in weekly milk samples throughout the experiment remained variable among the buffaloes. However, overall mean concentration of MU (mg dl-1) irrespective of periods remained lower (p = 0.01) in CFA fed buffaloes in comparison to control. It was concluded that composite feed additive reduces the milk urea concentration and protein degradation in rumen in lactating Murrah buffaloes.
