Effect of Feeding Microbial Feed Supplement in the Ration on the Performance of Lactating Cows

摘要

Fifteen lactating cows in early lactation with similar age, body weight and milk yield were selected from dairy farms of the local farmers and divided into three groups of five animals each. One group (T_1) as control was maintained on farmer's practices. While T_2 was fed concentrate mixture 1 kg/3 lit. milk yield and 15kg green fodder and T_3 was fed same as in T_2 + Microbial feed supplement @ 15g/day/head for 100 days. The average milk yield (kg/ day) was significantly (P< 0.01) higher in T_3 (7.84±0.21) as compared to T_2 (7.62±0.11) and T_1 (5.89±0.32) groups. The major milk components like fat content improved significantly (P<0.01) in microbial feed supplement fed group over control. Hence, it was concluded that feeding of microbial feedsupplement along with balance diet improved milk yield and fat percent as well as reproductive performance in lactating cows.
