Abstract:
Milk yield being the most important factor for profit in dairy industry is of great area of interest in scientific studies and research. Milk is being valued on the basis of its fat content mainly and other nutrient composition. But fat is the most important content of milk for which it is being priced of. The study was conducted to examine the effect of composite feed additive on fluctuation in weekly milk yield, fat corrected milk (FCM) and fat protein corrected milk (FPCM) in milk. 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. Fresh drinking water was offered ad libitum. Initial milk yield (kg d-¹) of both the groups were similar (p>0.05). Although there are differences in milk yield (kg d-¹) throughout the study, it was comparable (p>0.05) statistically between control and treatment groups. The values for weekly averages of 6% fat corrected milk (FCM) yield and fat protein corrected milk yield (FPCM) were also remained comparable between the groups.
