The complex use of probiotics effect on the ecological condition of the cowshed and the physiological animal state

Abstract

Violations of animals keeping and feeding conditions, especially dairy cows, lead to decrease in their productivity and deterioration in the quality of milk. The study of the complex use of probiotics effect on the microbiocenosis state of the cowshed and on the physiological state of black-and-white dairy cow organism. Against the background of the cowshed premises treating with the "Multi-25" complex containing thermophilic bacteria, a complex of bacteria of the genus Bacillus was fed to lactating cows at a concentration of 1×1010 CFU/gram, as well as mineral complex of natural origin and fermented soybean meal. As a result, the absence of a group of E. coli bacteria (coliform bacteria) was established in the places where flushes were taken in the room where cows of the experimental group were kept, as well as an average daily increase in milk productivity by 2.65 liters and obtaining better quality milk: the fat content was 0.8%, and protein 5.97% higher in comparison with the control group. Protein and mineral metabolism improvement was noted in the body of the experimental group cows.
