1 Composition of vitamin mineral mixture of 1 kg: Vitamin A—50,00,000 IU; Vitamin D3—1,000,000 IU; Vitamin B2—2.0 g; Vitamin E—750 units; Vitamin K—1.0 g; Calcium pantothenate 2.5 g; Nicotinamide—10.0 g; Vitamin B12—6.0 g; Choline chloride: 150.0 g; Manganese sulphate anhydrous: 27.5 g; Potassium iodide: 1.0 g; Ferrous sulphate: 7.5 g; Zinc sulphate heptahydrate: 15.0 g; Copper sulphate: 2.0 g; Sodium selenite, 0.1 g; Cobalt chloride: 0.45 g; and calcium carbonate: up to 1000 g. 2 NFE: Nitrogen free extract calculated using the following equation: NFE = 100 − (crude protein + ether extract + crude fiber + ash). 3 GE: Gross energy calculated on the basis of 23.6, 39.4 and 17.2 k joule gross energy g−1 protein, ether extract and NFE, respectively. 4 P/E ratio: protein energy ratio (mg crude protein kj−1 gross energy) = CP/GE × 1000 [33].
