Hulless barley in compound feed for broiler chickens

The most effective form of providing productive animals with nutrients remains high-quality compound feed. In order to realize the genetic potential of animals and poultry, it is necessary to look for ways to reduce the cost of compound feed without reducing the quality and balance of rations. Hulless barley characterized by a reduced content of difficult-to-digest fiber and therefore having increased nutritional value for poultry, is of particular relevance when introduced into compound feed. The purpose other work was to determine the efficiency of using hulless barley in compound feed for broiler chickens. The results of the eff ect of complete, balanced compound feeds with nutrients with the introduction of 15 and 30 % of hulless barley instead of wheat in compound feed for broiler chickens of the cross Smena-9 have been presented in the article. The results to base on rearing of broiler chickens, a positive eff ect of experimental diets with the introduction of 15 and 30 % of hulless barley on the digestibility of feed nutrients was established compared to the control: by 2.35–3.06 abs.% for crude protein, by 1.72–2.47 abs.% for crude fat, by 7–9.51 abs.% for crude fiber, by 0.63–1.22 abs.% for nitrogen-free extractive substances, which led to a lower average daily feed intake by 3.56 and 5.00 %. Due to the increased digestibility of nutrients, the live weight increased by 3.90–5.79 % (p < 0.001) and the yield of breast muscles by 17.25–27.29 %, while feed costs per 1 kg of live weight gain decreased by 6.67–9.59 % and the cost of 1 kg of broiler meat by 2.53–5.09 %. The use of hulless barley in feeding of broiler chickens allow us to increase the nutritional value of meat by increasing its protein content by 0.96–1.68 % (p < 0.001).
