Environmentally friendly protein supplements in poultry feeding

Research has been carried out to study the use of a new feed product prepared on the basis of ginger oil cake and feed concentrate from vegetable raw materials "Sarepta" in feeding poultry meat cross Ross-308. These feed products allow to increase the live weight, the digestibility of nutrients in the diet and improve meat productivity. The results of weighing of broiler chickens showed superiority in live weight of the II experimental group - 2612.76 g, where protein-vitamin-mineral concentrate BVMC (S) was used as an additive in compound feed in the amount of 7.5, 10 and 12%, respectively, during the start, growth and finish. The live weight of the I experimental group was 2512.54 g, where protein-vitamin-mineral concentrate BVMC (R) was used as an additive, the dosages were similar to the II experimental group. The weight of the control group chickens was 2370.80 g, respectively. The conducted experience showed that the chickens of the experimental groups exceeded the control analogues in the digestibility of dry matter by 0.27-0.57%, crude protein - by 0.45-1.48%, crude fiber - by 0.7-2.53%, crude fat - by 0.94-2.29%. The results of anatomical cutting of the carcass showed the superiority of the experimental groups.
