Abstract:
The invention relates to poultry farming, in particular to methods of feeding broiler chickens, and can be used in poultry farms to optimize nutrition and valorize alternative feed resources. The essence of the method consists in using an optimized level of 4.0% dried wine yeast as a feed additive in compound feeds intended for broiler chickens during growth phases (Starter phase: corn – 34.84%; wheat – 20.0%; soybean meal – 34.05%; soybean oil – 2.64%; limestone –1.97%; vitamin-mineral premix – 2.5%; wine yeast – 4.0%; Grower phase: corn – 38.37%; wheat – 20.0%; soybean meal – 30.31%; soybean oil – 3.42%; limestone – 1.40%; vitamin-mineral premix – 2.5%; wine yeast – 4.0%; Finisher phase (Period I): corn – 34.99%; wheat – 25.0%; soybean meal – 24.74%; sunflower meal – 3.50%; soybean oil –4.26%; limestone – 1.00%; vitamin-mineral premix – 2.5%; wine yeast – 4.0%), aimed at improving productive performance and economic efficiency, reflected in increased body weight, reduced feed consumption, and improved carcass yield. The additive contributes to more efficient feed utilization, increased body weight and carcass yield, while maintaining the normal physiological state of the birds and stable hematological and biochemical parameters.
