Impact of brewery waste on the productive and reproductive traits in Jersey crossbred dairy cattle

The study was conducted on twenty four Jersey crossbred dairy cows for a period of one year with three treatments to see the impact of brewery waste on productive and reproductive traits. The control (T0), brewery waste (T1) treatment and balanced ration (T2) treatment was carried out in farmer's field with eight animals in each group. The control, brewery and balanced ration animals were fed as per traditional and standard feeding practices. Productive traits viz., milk yield, milk fat, solids not fat (SNF), body weight were assessed before and at the end of experiment. Productive traits viz., lactation period and dry period and reproductive trait like number of services per conception (SPC) were also assessed. The results for milk yield and body weight showed that T0 is at par with T1 and T1 at par with T2 (P>0.05), and only in T2 significant increase (P0.05). Among the reproductive traits, no significant difference (P>0.05) is evident in lactation period between the treatments, with the values being higher for T2 (302.39 days) and lower for T0. With regard to dry period and SPC, no significant difference (P>0.05) is evident between treatments with values being higher for T0 (70.60 days & 2.16) and lower for T2 (63.11 days & 1.83). To conclude, balanced ration significantly increased (P<0.05) the milk yield and body weight of the animals followed by brewery waste and control in the descending order of magnitude.
