Abstract:

Dietary nutrients not only affect productive and reproductive performance but also milk composition traits like milk protein and milk lactose. This study was conducted to observe effect of copper and zinc feeding on milk protein and milk lactose when these are fed in pre and post partum stage to kankrej cows. Twenty Kankrej pregnant cows (five in each group) at 30 days before the expected date of calving were used to present study and grouped into four groups (five in each group) as control, copper supplemented, zinc supplemented and supplemented with both elements. Milk lactose and protein percentage were observed highest when both nutrient were fed together. The protein content was significantly (P≤0.01) higher on the day 7th of lactation and there was a decrease up to the day 45th. The milk lactose content (%) was significantly (P≤0.05) lower at day 45th of lactation. There was no significant effect of interaction due to the group x days.
