Digestibility of nutrients and morpho-biochemical status of calves when feeding probiotics
The main task of feeding dairy season is not only to ensure the optimal weight gain, but also to the settlement of the digestive system useful microflora and the fight against pathogens. Probiotic offer substantial help in solving this problem. Recently, spore-forming probiotics have been of increasing interest. They can withstand high temperatures and are not destroyed by digestive juices. Probiotic prescribed for prophylactic and therapeutic purposes should not only be safe, but necessarily effective, since these properties affect the economic component of the enterprise. The aim of the study was to determine the comparative effectiveness and safety of the sporinated probiotics “Olin” and “Triolin” in growing dairy calves in the conditions of the Oryol region. Research objectives: 1) establish the effect of the indicated drugs on the morpho-biochemical parameters of the blood of animals; 2) determine the intake and digestibility of nutrients in the diet of calves.
