Effects of Feed Additives and Supplement on Production Performance on Cross Breed Lactating Cows

The experiment was carried out for a period of 45 days (November, 2016 to December, 2016) split into 1 phase or 45 days i.e. winter season on crossbred cows at the Dairy Farm, Department of Animal Husbandry and Dairying, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. This experiment was conducted comprising three feed additive groups, with 18 crossbred cows in each group. The animals was randomly divided into 3 groups with 6 animals in each group.

(Table 1) ,6 cattle of group T2 was feeding mineral mixture(vitamin D3 ,vit.B12,Phosphorus,Calcium) supplement fed concentrate farm feed, roughages “B” as per recommendation which is 50gm/cattle/day (Table 2) and 6 cattle of group T3 was feeding mineral mixture (Vit.A,Vit.D3,Vit.E,Biotin,Niacin,Ferrous,Copper,Manganese,Zinc,Mg,Co,Iodine,Selenium,Chro mium and Potassium) supplement fed concentrate farm feed, roughages “C” as per instruction which is 50gm/cattle/day (Table 3). Milk yield was recorded at pretreatment (0 day) and post treatment (45 day).After complete experiment in three group of milk production T3(Treatment) group was increase total milk production.
