Proteinates of Microelements are a Way to Increasing Milk Quality

摘要

This paper reports on experience of using a feed additive based on proteinates of zinc, copper, manganese and selenium in various dosage. The studies have shown a positive influence on metabolic processes of cows during the increasing of milk production. Application of the feed additive facilitated increased digestibility of the main feed nutrients, as well as reduction of non-productive losses of gross energy with manure. Using the microelements allowed normalizing clinical blood scores, stimulating redox in the organism and promoting overall improvement of metabolism, increasing milk productivity and quality indicators of milk. Increased quantities of dry matter, fat and protein in milk have been registered. Introduction of the feed additive resulted in increased copper, zinc and selenium content in milk, which then may serve as a source of these elements in human nutrition.
