Abstract
A feeding trial was conducted to assess the cost of milk production, when brewery waste incorporated
concentrate based diet was fed in lactating cows for a period of 60 days. Eighteen early lactating
crossbred cows were selected from ILFC, TANUVAS, Madhavaram Milk Colony as the experimental
animals. The cows were divided into three groups as uniform as possible with regard to their age, body
weight, parity, previous milk yield and stage of lactation. They were randomly allotted to the three
dietary treatments T1, T2 and T3. The three dietary treatments were: T1, concentrate mixture, paddy
straw and green fodder; T2 and T3, concentrate mixture containing brewery waste at 40% and 80% level
(on DM basis).The total milk produced in 60 days by the animals fed the three dietary treatments T1, T2
and T3 were 2872 ± 10.75, 3200 ± 12.13, and 2950 ± 13.82 kg, respectively. The milk production was
comparatively higher in brewery waste fed groups (T2 and T3) than those fed control diet (T1). The cost
of feed per kg milk produced was Rs. 18.11, 14.01 and 12.66 respectively, for the three dietary
treatments T1, T2 and T3. The brewery waste fed groups (T2 and T3) had lower cost of feed per kg milk
produced compared to those fed control diet (T1), due to higher milk production and comparatively low
cost of feed. Based on the results obtained during the present investigation revealed that inclusion of
fresh(25 per cent DM) brewery waste reduced the cost of feed per kg milk production by 22 per cent and
30 percent by feeding brewery waste incorporated concentrate feed at 40% and 80% in lactating
crossbred cows producing about 10 kg milk per day.
