The purpose of the research was to determine the feasibility and effectiveness of using a natural antioxidant of plant origin – dihydroquercetin (DHA), as a biologically active substance, in combination with the main standard diet of broiler chickens. Scientific and economic experience conducted in production conditions on broiler chickens of the "COBB-500" cross allowed us to objectively establish that the addition of the biologically active substance Dihydroquercetin to mixed feed contributes to the increase in meat productivity and safety of broiler chickens. Feeding of broiler chickens was carried out with full-fledged compound feeds, in accordance with the recommendations of the originator for this cross. In terms of energy nutrition and the content of nutrient active substances, they were the same and differed between the groups in the amount of the additive administered. Chickens of the 1st control group received only feed (basic diet), the 2nd experimental group – advanced antioxidant supplement Dihydroquercetin in the amount of 0.5 g per 100 g of feed, the 3rd – 0.75 g per 100 g of feed, and 4th – 1 g per 100 g of feed. The duration of the experiment was 40 days and to clarify the effectiveness of increasing the duration of the broiler fattening period, it was extended to 60 days. Broiler chickens were reared on the floor, temperature and light conditions, air humidity, feeding and watering front of the bird during the experiment corresponded to the recommended standards. As a result of the conducted studies on the effect of adding optimal levels of biologically active feed additive Dihydroquercetin to the diet of broiler chickens, it was found that during the growing period, a higher coefficient of live weight gain was established in broiler chickens of the 3rd and 4th experimental groups, whose live weight increased by 105.32 and 120.48 times by the age of 40 days, while in broiler chickens of the 2nd experimental group by 102.57 times and the lowest–in control group chickens only in 90.96 times. The selected feed additive can be considered as an alternative to the use of feed antibiotics in the feeding of broiler chickens in industrial poultry farming technology.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

This article presents the results of the effective use of biologically active substance that belongs to hydrolyse class “Lysozyme G3” in the composition of pigs premix. New premix that can balance the main grains in pigs feeding has been developed. The main grains are wheat, corn, barley. These compounds are included into pigs feeding ration and they are the main crops in the South of Ukraine. The effect of using this new premix that contains the enzyme preparation “Lysozyme G3” for fattening pigs was also investigated. The productive effect of enzyme preparation in the rations with the same nutritional value for fattening pigs and its effect on the nutrients digestibility were studied. Experimental research activities were conducted at the agricultural enterprise “Avangard-D” LLC, Ovidiopol District, Odessa Oblast. The changes in live weight, as well as gains of fattening pigs at the age of 4, 5, 6 and 7 months were studied in the scientific and economical experience. During the main period (120 days), the increase in pigs live weight was observed in all groups. Thus, in the control group, this indicator changed from 27.8 to 107 kg; in II experimental group – from 28.1 to 109.2; in III experimental group – from 28.0 to 111.7 kg. When removing animals from fattening, the difference in live weight between the III experimental and control groups was 4.4% and it was statistically significant (P > 0.95). The average daily gains in piglets of II and III experimental groups significantly exceeded the indices of control one by 2.4% and 5.7%, respectively. The nutrients digestibility in animals of all experimental groups was studied to analyze more carefully. The analysis of digestibility indices in pigs rations during experiment (when pigs are fed with premix that contains biologically active substance Lysozyme G3), and its content in the ration indicated that nutrient digestibility indices had changed into the direction of increase. Feed consumption was calculated after analyzing these indices. Thus, the smallest feed consumption per unit of live weight gain was established in the third experimental group, where it was 3.2 feed units and was less in comparison with animals of the control group by 3.4%. During scientific and economical researches, blood samples were taken from animals of the first control group and the third experimental one for morphological and biochemical studies. It was found that the blood parameters of experimental animals during the entire period of fattening were within the physiological norm. The amount of protein in the blood indicates that animals of experimental group have higher growth rate by 10.9%. The economic indicators directly reflected above mentioned facts when the calculation of the economic part of the research were carried out. Thus, we got 1870.5 UAH from the first group, 1934.3 UAH from the second group, 1989.4 UAH from the third group, selling products from one head. Accordingly, the level of profitability of pork production was: in the first group (control) – 13.5; in the second (1 kg/ton of premix) – 16.5%; in the third (2 kg/ton of premix) – 19.8%.

The intensifi cation of modern industrial poultry farming as the most progressive and dynamically developing branch of agriculture aimed at raising productivity and increasing production volumes, inevitably leads to numerous problems related to poultry health. One of the most common ways to solve this problem is to use antibacterial drugs. The results of scientifi c and economic experiment on the use of the phytobiotic additive “Farmatan VSO (Butitan)” in feeding broiler chickens of cross Cobb-500 have been provided in the article. The inclusion in the poultry diet of the phytobiotic “Farmatan VSO (Butitan)” in the amount for compound feed Start 800 g/t, Growth and Finish – 400 g/t leads to increase in the live weight of broilers by 3,0 % compared to the control group. At the same time the average daily gain of live weight in the 4th experimental group was 73 g, which was by 2,8 % more than in the control group. The use of phytobiotic additives in the feeding of broiler chickens contributes to the highest livability of poultry (98,1 %). It has been found that the best indicators for feed expenditures have been noted in the 3rd and 4th experimental groups 1,47 and 1,48 kg, which were 3,3 and 2,6 % lower than in the control group. Thus, the authors have found that the highest live weight, average daily gain, livability and lowest expenditures of feed per unit of production diff ered in broiler chickens of 4th experimental group where in the compound feed antibiotic Flavomycin has been replaced on phytobiotic feed additive “Farmatan VSO (Butican)” in the compound feed Start 800 g/t, Growth and Finish- 400 g/t. Production testing of the use of “Farmatan VSO (Butitan)” has shown the high eff ectiveness of phytobiotics as a mean of replacing the feed antibiotic and improving the livestock indicators of broiler chickens rearing.

This article reflects the results of the development of a method for testing a promising feed supplement based on the Lactobacillus plantarum strain, with a high antagonistic activity to campylobacter. To determine the digestibility and use of food nutrients by broilers, a physiological (balance experiment) was conducted on three males from each group at the age of 28 days. By the end of the growing period, there was a clear tendency to increase the live weight of 36-day-old chickens compared with the control group in experimental group 2, which received a feed supplement, including bacteria Lactobacillus plantarum. She was 4.0% higher. As a result of scientific work, it was shown that feeding broiler chickens with a probiotic feed additive based on Lactobacillus plantarum helps to increase their productivity during the entire growing cycle.

The authors of this article evaluated the effectiveness of the use of a feed additive based on soy protein hydrolysate of the enzymatic cleavage method in combination with iodine and selenium in broiler chickens in the framework of studying its pharmacological properties. The indicators of livestock safety in the experimental group by the end of the experiment were 100.0 %, and in the control group − 84.0 %. In the experimental group, the increase in live body weight was 13.9 % higher compared to the group that did not receive a feed supplement. According to the calculations, the cost of compound feed per 1 kg of weight gain of poultry during the growing period in the ex-perimental group was 1.8 kg, which was 14.2 % lower compared to the control group. The slaughter yield of carcasses in the experimental group was 66.7 %, while in the control group − 62.0%. During the veterinary and sanitary examination, it was determined that the meat of the experimental and control group of broiler chickens was obtained from a healthy bird and was of good quality and suitable for further processing.

The use of different feed processing methods using exogenous feed additives to improve the digestibility of plant feed ingredients in pig feeding has been studied for decades. In the research laboratory of the Institute of Forage and Agriculture of Podillya NAAS, compositions of enzymes with cellulase and amylase activity were studied. They are able to effectively break down non-starch polysaccharides in cereals, increase digestibility and absorption of feed nutrients. The purpose of this work was to study the zootechnical efficiency of the use of biologically active in the composition of feed pigs for fattening. In the presented material, the influence of feeding cellulose amylolytic enzyme additive on the productive qualities of pigs for fattening is highlighted. The cellulose amylolytic additive contained α-amylase with an activity of 9342 IU/h and cellulase with an activity of 540 IU/h. Studies in pigs were performed in two stages: the equalization period (15 days) and the main (71 days). For feeding pigs, a feed mixture was used, consisting of feed grown directly on the farm – barley, wheat, soybeans. The diet of the control group consisted of 63 % barley grain, 27.5 % wheat grain, 9 % soybean meal 0.5 % mineral supplement. Pigs of the experimental group were fed cellulose amylolytic feed additive at the rate of 5 g of cellulase and 1 g of amylase per 1 kg of feed. Feeding supplements determines the intensity of the process of digestion of proteins, fats and carbohydrates. Cellulose-amylolytic additive affects the absorption of carbohydrates in the diet, providing an increase in the digestibility of the control and experimental groups, respectively, neutral-detergent fiber (38.2 and 46.7 %), acid-detergent fiber (18.7 and 36.5 %), the amount easily hydrolyzed carbohydrates (85.4 and 90.2 %), hemicellulose (65.7 and 61.5 %), cellulose (13.2 and 21.4 %). The decision on the feasibility of including cellulose-amylolytic additive in the diet can be confirmed on the basis of its use during the scientific and economic experiment. In the control group, the average daily increase in live weight was 725.07 g, and in the experimental group by 19.7 % more at the level of 902.53 g. It was also noted a positive effect on the formation of body biomass, development of individual organs and their systems.
