EXPERIENCE OF USING A PROTEOLYTIC ADDITIVE IN FEEDING BROILER CHICKENS
The article presents the results of the application of a proteolytic enzyme - protease - in broiler poultry farming. The results of the studies have shown that the introduction of the enzyme in the recommended dosage in the diets of poultry meat contributes to an increase in productive indicators, such as live weight and feed conversion. Introduction. Poultry farming is a dynamically developing branch of agriculture from year to year. Most countries of the world rely on poultry enterprises, primarily because of the speed of production, quantity and quality of the resulting product. Supplying the country with high-quality dietary meat is the primary task of the state, in which poultry enterprises actively participate. Broiler chickens are the most promising poultry for growing at poultry enterprises both in Russia and in the world. Due to strict compliance with zootechnical and veterinary standards for the cultivation of this bird, it is possible to obtain a large amount of meat in record time, which is why the number of broiler farming enterprises is increasing every year. To improve production performance, industrial enterprises include antimicrobials, probiotic feed additives, acidifiers, salts of organic acids, as well as enzyme feed additives in feed. Enzymes (enzymes) are complex protein compounds that accelerate chemical reactions in living systems, for us, enzyme feed additives not only accelerate, but increase the digestibility of nutrients. All enzymes are specific to the chemical bonds of a certain group of substrates. An object. The object of research was broiler chickens of the Cobb-500 cross. Materials and methods. In our experiment, we tested the effectiveness of including a proteolytic enzyme (protease) in the diets at a dosage of 250 g/t. The experiment was carried out in the conditions of the scientific and production laboratory of poultry farming of the UNIC "Agrotechnopark" of the Belgorod State Agrarian University. Results and conclusions. This enzyme has shown its effectiveness when monoincluding in mixed poultry feed. So at the end of the experimental period, the live weight of broiler chickens of the control group was less than the weight of broiler chickens of the experimental group by 95.3g or 3.9%. Feed costs per 1 kg of live weight gain in broiler chickens of the experimental groups amounted to 1.77, which is 0.06 kg less than the control.
