Hematological parameters and micro biocenosis gastrointestinal tract of calves fed with the feed additive “Laktur”

In the last decade the concept of probiotics has undergone significant changes. It shows increasing attention of researchers in structural components and metabolic products of probiotic microorganisms. These changes are associated with the extension of the concepts of biological effectiveness of probiotics and detecting the fact that the structural elements of the cells and their metabolites in many cases are at least equally effective. Feed probiotic preparations are widely used in animal husbandry practices, allow improving the existing system of modern rational animal feed. Lactic acid bacteria, streptococcus bacteria and Bacillus subtilize, a part of the enzymatically-probiotic feed additive “Laktur” mobilize useful synthesis of biologically active components in the body, inhibit the growth of opportunistic pathogens, restore normal intestinal microbiocenosis and contribute to the prevention of gastrointestinal diseases of animals. Hematologic studies revealed that the feed additive “Laktur” through a variety of functions has a positive effect on erythropoiesis calves. Thus, the number of erythrocytes in the blood of calves treated with the feed additive “Laktur” in a dose of 1.25 kg/ton by weight of the concentrated feed was more than the control animals at 8.24 % (P
