The use of the probiotic Cellobacterin-T in the diets of young chickens of the cross Brown Nick

Abstract

According to the research results of domestic scientists and poultry breeders, the industrial use of multifunctional feed additives based on beneficial bacteria ensures the improvement of zoo technical and economic indicators of poultry farming, as well as the quality of the products obtained. The purpose of the work was the scientific and production justification of the optimal dosage of the enzymatic probiotic Cellobacterin-T in the diets of young chickens of the egg production direction of the cross Brown Nick. Experimental studies were carried out under the production conditions at the OOO “Avangard” poultry farm in the Ruzaevsky municipal area in the Republic of Mordovia. Four groups of young chickens (a control group and three experimental ones) were formed to conduct the research. The young poultry of the control group received the basic diet. The young poultry of the experimental groups received the basic diet with the inclusion by step mixing of the enzymatic probiotic Cellobacterin-T. To the chickens of the 1st experimental group Cellobacterin-T was additionally added to the basic diet at the rate of 70 mg/100 g of compound feed, the 2nd experimental group Cellobacterin-T was additionally added 100 mg/100 g of compound feed, the 3rd experimental group Cellobacterin-T was additionally added 130 mg/100 g of compound feed. As a result of scientific and economic and balance experiments, the optimal dosage of the drug was determined as 100 mg/100 g of compound feed. During production testing with the optimal dosage of the probiotic Cellobacterin-T, it was found that the use of the additive at the dose of 100 mg/100 g of compound feed reduced the prime-cost of producing 1 kg of live weight gain by 1,96 rubles, and increased the level of profitability of production compared with the control group by 1,88 abs.%.
