The protein energy relation optimization in the diets of Yenisei type red-marked breed heifers in non-milking period and first calf heifers at the beginning and middle phases of lactation

The efficiency of fodder additive Mikrobiovit Enisey use, the micro-toxin adsorbent Fungistat GPK-1, 1%, polysaccharides Minvit KAP, vegetative albuminous product Belkov-M in feeding cows of the Yenisei type red-marked breed is studied. It is revealed that introduction of bio-additives and the concentrated protein of 8-23 % in recalculation of forage solid substance into the cow daily diet facilitated the useful microflora increase in the gastrointestinal tract, hem motility strengthening, decrease in pathogenic microflora to alkaline flora restoration, live weight increase, milk yields increase, reproductive function stabilization, normalization of blood morphological and biochemical composition.
