 ABSTRACT

The study was conducted to examine the effect of composite feed additive on fluctuations and correlation of milk lactose and 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 CFA fed group along with concentrate mixture. The urea conc. (mg dl-1), lactose and milk protein in milk of experimental buffaloes at weekly interval was recorded. In the initial stages of lactation MU concentration and lactose were 35.71±7.81 and 35.23±4.7, 4.51±0.23 and 4.52±0.22 respectively in control and treatment group. The concentration of MU and lactose 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.

Key words: Milk urea, Lactose, Composite feed additive, Buffaloes
