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 %.

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.

Effect Of Feeding

The results of the effect of feeding the chelated form of Zinc on the safety, productivity and slaughter parameters of broiler chickens are presented. The aim of this study was to determine the safety, productivity and slaughter parameters of broilers on the background of feeding chelated form of Zinc. Materials and methods. Experimental studies were conducted during 2020 on broiler chickens cross Cobb-500 in the vivarium of the Veterinary Faculty of Sumy National Agrarian University (Ukraine), divided into two groups on the principle of analogues (control and experimental) of 50 broilers each. The source of zinc for chickens in the control group was their sulfates. Chelated forms of Zinc were used for broiler chickens of the experimental group. All groups of broiler chickens were administered the compound with compound feed in a dose that corresponded to the daily requirement of the bird in this trace element. The duration of the experiment is 42 days. The growth and development of broilers were evaluated on the basis of determining the relevant zootechnical indicators. Live weight of birds was determined by individual weighing on scales of the VNC type with an accuracy of ±1 g at the age of 7, 14, 21, 28, 35 and 42 days. Both scientific and economic experiments also determined the preservation of livestock - daily by the number of culled and dead birds. Feed consumption was recorded daily, for each week of cultivation and for the entire period of the experiment. At the end of the experiment, the cost of feed per 1 kg of live gained weight was calculated. Results. According to the results of the conducted researches, it was established that feeding of the chelated form of Zinc probably increased both the average daily gain and the total live weight of broiler chickens at different age periods of rearing. The live weight of chickens at the beginning of the experiment was almost the same, but at 7 days of age it tended to increase in chickens of the experimental group, although a significant difference between groups in this indicator was not found. It was found that the weight of uneviscerated, semi-eviscerated and eviscerated chicken in poultry of the experimental group was greater than similar indicators in the young animals of the control group by 9.3, 9.2, and 9.8 %, and this difference was significant (p<0.01). The yield of semi-eviscerated carcasses was higher in ones of the experimental group (84.19 %), and the difference was significant (p<0.05). Conclusions. It was found that the live weight of chickens of the experimental group (consumption of feed with a chelated form of Zinc) prevailed at 7 days of age by 1.1 g; on the 14th day – on 22.1 g (p<0.01); at 21 days – 35.4 g (p<0.01); at 28 days – 94.5 g (p<0.05); at 35 days – 133.6 g (p<0.01); at 42 days – at 218.9 g (p<0.05). Preservation of young animals in the experimental group, which used chelated compounds of Zinc, was higher and amounted to 96 %, compared with the control – 92 %. By age, feed costs per unit weight gain were lower in the experiment, respectively: 0.05; 0.08; 0.12; 0.06; 0.07 and 0.05 kg, compared to the control group. Growing broiler chickens on compound feed with a chelated form of Zinc by 9.8 % (p<0.01) increases the weight of the eviscerated carcass.

The possibility of including SUB-PRO probiotic instead of Maxus G feed antibiotic in the diet of broiler chickens of Ross 308 cross was studied to obtain products free of drugs for antimicrobial resistance usage. The dynamics of live weight and carcass weight of cockerels at 1-, 21-, 28-, 34-, 38- and 42-days old was determined. The males of the control group (group 1) reached live weight of 2619 ± 44.9, experimental - 2739 ± 46.2 or more by 4.38%, at P≤0.05 by 42 days of age, and those which received feed antibiotic ( group 3) - 2677 ± 45.1 (further, meat productivity of the latter was not studied, since they are not of practical importance). The mass of carcasses of the experimental group was equal to 1704 ± 23.1 g, which is 4.60% more than the control, at P≤0.05; the relative mass of muscle tissue increased with age by 10.78% in the experimental group in comparison with the 1-day -olds, in the control group - by 10.0%, whereas the mass of bones decreased by 16.75 and 16.59%, respectively (by the difference); the diameter of muscle fibers of superficial pectoral muscle of 42-day-old broilers of the experimental group increased with age by 6.94 times and amounted to 57.9 μm; in terms of microbiological parameters, carcass meat meets the requirements of the interstate standard GOST 31468—2012. At the age of 42 days, cockerels of the control group showed dystrophic changes in the superficial pectoral muscle in the form of an expansion of the endomysium diameter, with the accumulation of interfiber fluid (albuminous degeneration), while some cockerels of the experimental group have fibers with vacuoles and infiltration by immunocompetent cells (leukocytes, phagocytes). Adding SUB-PRO probiotic in the broilers’ diet instead of the feed antibiotic does not reduce productivity, but excludes the negative consequences of feed antibiotics.

The development of industrial poultry farming requires not only the breeding of new highly productive poultry breeds, but also the development of new rearing technologies and the improvement of standardized nutrition. Currently, in the field of feeding farm animals and poultry an important research area is the search for cheaper non-traditional and affordable feed products that can replace part of the grain in the poultry diet. It is very important to use local raw materials. One of these crops is naked oat, which has the highest energy content, the highest concentration of lysine and methionine among all cereals. The purpose of the researches was to determine the eff ectiveness of using naked oat in compound feed for quails. The results of the influence of complete nutrient-balanced compound feeds with naked oat on zootechnical and economic indicators in the rearing of quails have been presented in the article. It has been found that the live weight of quails in the experimental group has been increased by 3,06 %, while the average daily feed consumption has been increased by 1,83 %. Feed expenditures per 1 kg of live weight gain in the experimental group have been lower by 1,31 % due to the absorption of feed nutrients. According to the results of the balance experiment, the digestibility of raw protein has increased by 1,90, fat by 0,41 %, nitrogen-free extractive substances by 2,77 %. When calculating economic indicators, it has been found that the use of naked oat in compound feed for quails allowed to increase the yield of meat and revenue from its sale by 3,75 %. Despite an increase in the total cost of feed consumed by the experimental group by 2,27 %, the profi t has been received by 9,59 % more. The level of profi tability of quail meat production in the experimental group exceeded the indicator of the control group by 3,40 %.

Изучены особенности пищевого поведения коров-первотелок при скармливании ферментативно-пробиотических препаратов. Для изучения влияния пробиотиков на основе целюлозолитических бактерий рубца жвачных проводился опыт в условиях хозяйства Вологодской области. Были сформированы 3 группы первотелок черно-пестрой породы по 12 голов методом пар-аналогов с учетом кровности, удоя матерей за наивысшую лактацию, живой массы, количества дойных дней после отела и суточного удоя. Животные контрольной группы получали основной рацион,  коровам I опытной группы дополнительно скармливали по 50 г на 1 голову в сутки кормовую добавку на основе целюлозолитических бактерий рубца коров, а II опытной — такое же количество добавки на основе целюлозолитических бактерий рубца оленей. Продолжительность скармливания добавок составляла 90 дней. В результате исследований было установлено, что использование ферментативно-пробиотических препаратов положительно повлияло на пищевую активность и уровень молочной продуктивности первотелок. Коровы I и II опытных групп, получавшие дополнительно к основному рациону ферментативно-пробиотические препараты в сравнении с контрольной группой имели более высокие показатели по затратам времени на потребление корма — 8 и 25 мин., соответственно. Время, затраченное на жвачку, у первотелок II опытной группы было больше на 12 мин., чем у животных контрольной группы, в результате индекс пищевой активности у них был выше на 0,026 по сравнению с контролем. Использование добавок способствовало увеличению молочной продуктивности коров I и II опытных групп, по сравнению с контрольной, на 207 и 151 кг. Полученные результаты подтверждают положительное влияние ферментативно-пробиотических препаратов в кормлении коров, так как они способствуют повышению их пищевой активности и молочной продуктивности. The features of first-born cows’ nutritional behavior when feeding enzyme-probiotic preparations have been studied. To study the effect of probiotics based on the ruminants’ cellulolytic rumen bacteria, an experiment on a farm in the Vologda Oblast has been conducted. There were formed 3 groups of black-and-white first-born cows of 12 heads by the method of pairs-analogues, taking into account pedigree, mothers’ milk yield for the highest lactation, live weight, the number of milking days after calving and daily milk yield. The animals of the control group received the main diet, the cows of the I experimental group were additionally fed 50 g per 1 head per day of a feed additive based on cellulolytic bacteria of cow rumen, and the II experimental group were fed the same amount of an additive based on cellulolytic bacteria of deer rumen. The duration of feeding the additives was 90 days. The research found that the use of enzyme-probiotic preparations had a positive effect on the first-born cows’ nutritional activity and milk productivity level. The cows of the I and II experimental groups who received enzyme-probiotic preparations in addition to the main diet had higher indicators for the time spent on feed consumption in comparison with the control group — 8 and 25 minutes, respectively. The time spent on rumination was 12 minutes longer in the first group of experimental animals than in the control group; as a result, their food activity index was higher by 0.026 compared to the control group. The use of additives contributed to an increase in the milk productivity of cows of the I and II experimental groups, compared with the control group, by 207 and 151 kg. The obtained results confirm the positive effect of enzyme-probiotic preparations when feeding cows, as they help to increase their nutritional activity and milk productivity.

Poultry Farming

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.

The article analyses the issues of balanced feeding of broiler chickens and their balanced diet. The results of studies aimed to determine the effect of mixed feeds on the productivity of Arbor Acres cross broiler chickens and the economic efficiency of poultry meat production companies are presented. It was found that broilers from the experimental group, who were fed with improved compound feed with additional sources of proteins and carbohydrates and feed additives exceeded broilers from the control group by their live weight at all ages. At the slaughter age, the average weight was more than 39.2%. The experimental group consumed 10-15% less feed whose conversion was 2.4 and 1.9 kg in favour of the group feeding with the new compound feed. The new compound feed had a positive effect on the viability of broilers: there were no deaths during the period under study. According to the control slaughter results, it was found that the pre-slaughter live weight was higher by 35% in the experimental group. The weight of edible parts increased by 6%. The improved compound feed can be used both in industrial conditions and by poultry farms.
