The effect of lactobacilli and a selenium-containing preparation on a certain macronutrient composition in the blood of the body
The complex application of lactobacilli and selenium preparation is considered, which made it possible to optimize a certain mineral status of the macroorganism, which had a positive effect on the course of biochemical processes. The object of the study was broiler chickens of the Smena-7 cross. In the experiments, we used sodium selenite (Na2SeO3) TU 6-09-17-209-88 qualification «Ch» at a dose of 0.2 mg/kg feed and the probiotic tetralactobacterin, at a dose of 1.0 g/kg of feed, which was obtained in the laboratory of biotechnology of microorganisms. The calcium: phosphorus ratio in the blood serum of chickens during the starting period was 1.33: 1.00, by the middle of the experiment it varied within 1.27: 1.00 - 1.29: 1.00, by 42 days of age - within 1.27: 1.00 - 1.30: 1.00. The concentration of magnesium in the blood serum of broiler chickens of all groups increased slightly. Analysis of the exchange of total calcium, inorganic phosphorus and magnesium in broiler chickens of the Smena-7 cross with the inclusion of tetraloctobacterin and sodium selenite showed that in a laboratory study the studied parameters did not go beyond the reference values. The additives introduced had a positive effect on mineral metabolism, stimulating the exchange of calcium, phosphorus and magnesium, contributing to a favorable bowel function. Due to the use of a rational feeding scheme for the probiotic and the selenium preparation, it became possible to increase the amount of necessary components in the meat, which improves the quality of poultry products, making it possible to obtain food products with the desired properties
