Abstract
The article presents the research results on the vitaminselenium-containing preparation (1.0 l / t) using effectiveness in the broiler chickens diet in combination with enzyme preparations “CelloLux-F” (100 g/t, experimental group I), “Protosubtilin G3x” (60 g/t, experimental group II) and “Amylosubtilin G3x” (200 g/t, experimental group III). It was found that the broilers of the experimental groups exceeded the average live weight by 2.74-4.95%; dry matter digestibility - by 0.89-1.58%, protein - by 1.41-2.71%, fat - by 1.16-2.03%, fiber - by 0.82-1.69 and nitrogen-free extractive substances - 0.74-1.43%, nitrogen use - by 1.35-2.99%; drawn bird weight - by 2.93-5.89%, edible carcass parts - by 3.33-6.47%, pectoral muscles - by 3.53-7.83%. In the experimental groups broiler chickens, the meat quality indicators are improved: dry matter content in the pectoral muscles - by 0.30; 0.12 and 0.07%, protein - by 0.41 (P <0.001); 0.16 (P <0.01) and 0.13% (P <0.05). The experimental broilers groups slightly exceeded the control group in terms of the biological value and the pectoral muscles meat culinary and technological properties. Redox and metabolic processes were more intensive in young animals of the experimental groups than in the control one. Among the experimental groups, the meat productivity and quality highest indicators were noted in broiler chickens of the I-st experimental group, they received the preparation “Carcesel” in combination with the enzyme preparation “CelloLux-F”.
Highlights
The problem of the agricultural animals and poultry products production intensifying is currently one of the most urgent in Russia, as in many countries of the world, since it is directly related to the use of innovations and science-intensive technologies that play a key role in providing the population with high-quality, environmentally friendly, competitive products [9]
Based on the mentioned above, the purpose of this work was to study the vitaminselenium-containing preparation "Carcesel" in combination with enzyme preparations influence on the broiler chickens meat productivity and physiological parameters
The studies found that the preparation "Carcesel" application into the experimental groups broiler chickens diets in combination with enzyme preparations showed the increase in erythrocytes, respectively, by 8.3 (P
Summary
The problem of the agricultural animals and poultry products production intensifying is currently one of the most urgent in Russia, as in many countries of the world, since it is directly related to the use of innovations and science-intensive technologies that play a key role in providing the population with high-quality, environmentally friendly, competitive products [9]. In this regard, it is necessary to change qualitatively the feed base nature through the creation and use of effective biologically active additives and preparations of a new generation, which have nutritional value, and protective effects on the poultry organism [8]. It is known that grass meal during the storage loses its nutritional properties, unlike carotene-containing feed additives of industrial production. As an alternative to natural sources of carotenes, the modern industry produces beta-carotene-containing preparations with high stability, bioavailability and antioxidant properties against mycotoxins entering the body [1, 2, 4, 11]. The poultry productivity genetic potential realization is impossible without proper and high-quality feeding. Based on the mentioned above, the purpose of this work was to study the vitaminselenium-containing preparation "Carcesel" in combination with enzyme preparations influence on the broiler chickens meat productivity and physiological parameters
