APPLICATION OF FERMENTATIVE PROBIOTIC CELLOBACTERINE-T FOR IMPROVING FEED CONVERSION IN POULTRY INDUSTRY
The author highlights the research results on exploring the scheme of application of enzyme probiotic Cellobacterine-T produced by Biotrof enterprise in St. Petersburg. This probiotic is a complex of cellulolytic and lactic acid bacteria isolated from rumen of ruminants and selected on the parameter of high ability to decompose cellulose. This allows to use the specimen in poultry ratio with high concentration of wheat, barley, sunflower protein meal and seed cake. Cellobacterine-T acts like a probiotic when it contributes to stable poultry digestion. The researchers offer to apply Cellobacterine-T dosed 1 kg/t for chickens aged 3 months and increase the dose on 50% - 1.5 kg/t when ovogenesis organs are being formed; at the peak of egg-laying capacity - 2 kg/t; at the final stage to use standard dose 1 kg/t. Feed accessibility and digestibility are high and this contributes to better feed conversion, reduces palatability on 8-140 g per each laying hen. Egg laying capacity of experimental hens which were fed with Cellobacterine-T dosed 2 kg/t for two months has reached 98% against 61, 66, 71% in the control group. Feeding laying pullets with Cellobacterine-T improves poultry evenness to the beginning of fertile period, which increases egg laying capacity on 8-12% and reduces feed costs on 5-7%. Cellobacterine-T increases average daily growth on 3-10% and feeding costs on growth on 9-15%. Cellobacterine-T increases application of sunflower protein meal in growth and finish ratios up to 20-30% regardless reducing livestock parameters.
