Production test of using feed additive "Chitosan complex "KH-Aqua" in growing broiler chickens

In industrial rearing of modern cross broiler chickens, the priority task is to maximize their genetic productivity potential and reduce feed costs per unit of production. A relevant area is industrial testing of new feed and biologically active additives in broiler poultry farming. The aim of the study was to scientifically and practically substantiate the use of the feed additive "Chitosan Complex "KH-Aqua" to improve the zootechnical and economic efficiency of industrial rearing of broiler chickens. The feed additive "Chitosan Complex "KH-Aqua" was produced by Agrokhitin LLC (Nizhny Novgorod) and is available in liquid form. It contains the following components: purified water - 89%, chitosan with different molecular weights - at least 7%, as well as succinic, ascorbic, lactic and acetic acids. The feed additive does not contain antibiotics, palm oil, hormonal preparations and growth stimulants. According to the results of two production trials, it was established that the use of the feed additive "Chitosan Complex "KH-aqua" from the 16th to the 18th day and from the 24th to the 35th day of life in the amount of 0.5 l per 1 ton of drinking water had a positive effect on the productivity, safety of chickens, contributed to a reduction in feed costs per 1 kg of live weight gain, an increase in meat yield per unit of useful area of the poultry house and an increase in the economic efficiency of production. The economic efficiency of using the chitosan complex for one technological cycle of growing broiler chickens in the new version amounted to 174,081.09 rubles. The level of profitability in the new growing option increased by 3.1 percentage points compared to the base one.
