Optimization of microelement nutrition of lactating cows and its effect on milk composition and cheese quality
In the conditions of sub-mountain zone of the Altai Region by experimental method optimal availability to animals of salt complex of such microelements as copper (10 mg), zink (60 mg), cobalt (1 mg), iodine (0.6 mg) in 1kg of dry matter was achieved by application of Polinorm premix. That promoted milk yields by 8.1-18.9% as well as fat, protein and microelement content. The quality of the Soviet cheese made of such milk improved as well.
