- Abstract
The effect of copper and zinc supplementation on milk composition like milk fat, milk SNF and milk total solid was tested in pre and post partum feeding trial, with 20 lactating Kankrej cows, divided in four groups (control, copper, zinc, and copper-zinc combination). Milk fat percentage was observed highest in supplemented combination group while milk SNF and total solid were highest in zinc supplemented group. The significant effect ((P≤ 0.05)) of micronutrient supplementation on milk fat, milk SNF and total solids was observed in present study. The fat content was significantly (P≤ 0.01) high during the first days of lactation and decrease up to the day 45th. The interaction effect due to the group x days was found non-significant. Thus improvement of the nutritional status improved the milk production as well as milk composition.
