Improving the efficiency of poultry meat production by feeding ultrafine silicon

Abstract

The article presents the results of a study on the effect of various doses of ultrafine silicon on the microbial content of the intestines and blood parameters of poultry. The microbiology of digestion is very complex and poorly understood. It was found that ultrafine silicon particles selectively affected the intestinal micro flora of chickens, reduced the number of pathogenic microorganisms, thereby increasing the number of lactobacilli in the total mass. Useful microorganisms can significantly increase the bioavailability of the feed used. It also has a positive effect on the content of red blood cells and by the middle of the experiment, their number was significantly higher in the experimental groups by 4.74-7.79 %, and by the end of the experiment-by 4.38-9.04% compared to the same indicator in the control group. The hemoglobin content in the blood of chickens also increases in comparison with the beginning of the experiment. By the end of the accounting period, in the 1st (dose of 100 mg/kg of feed from ultrafine si particles), 2nd (dose of 200 mg/kg of feed from ultrafine Si particles) experimental groups, the level of hemoglobin decreased by 4.78-5.06%, in the 3rd (dose of 300 mg/kg of feed from ultrafine Si particles) and 4th (dose of 400 mg/kg of feed from ultrafine Si particles) experimental groups, where the highest concentration of silicon in the feed was observed, increased by 12.0 %. There was also an increase in the total protein in the blood of the experimental bird by 3.05-5.45% by the middle of the experiment and by 10.08-11.58% by the end of the experiment. The albumin fraction content also increases by 10.48-3.10 %. Thus, the data obtained during the study reflect the body's response to various doses of ultrafine silicon used in poultry feeding. The obtained result shows the possibility of using these forms in the industrial production of animal feed.
