The effect of top dressing on the growth and development of crossbred young sheep in the farm Mikhalchenko P.V. Yashkulsky district of the Republic of Kalmykia

Abstract

Protein-vitamin-mineral supplements, or BVMD for short, play an important role in feeding sheep. They balance diets based on vitamins, minerals, micro- and macro-elements. BVMD is used as an additive in concentrated feed. The additive is introduced into the feed in an amount of 10-20% of the total weight. The BVMD additive provides farm animals with the necessary nutrition elements, increases live weight gains, increases animal productivity, increases fertilization and safety of offspring, reduces feed costs for the production of a unit of production. The source of vitamins in BVMD are water-soluble and fat-soluble vitamins. For example, B vitamins, vitamin A, vitamin D3, vitamin E. The source of minerals in BVMD are: table salt, monocalcium phosphate, limestone and mineral mixtures that contain iron, selenium, zinc, cobalt, copper, iodine and others. They can also use fish, bone, meat and bone meal. BVMD should not be fed to animals in its pure form, as this can lead to poisoning. Therefore, BVMD is used with concentrates. The percentage of BVMD application in concentrates ranges from 10 to 20%. Thus, BVMD is necessary to replenish the feed with necessary substances that the animal’s body cannot synthesize on its own.
