The growth rate and bone metabolism indicators were monitored in broiler chickens receiving the feed supplemented with clinoptilolite. One-day-old broiler chickens ROSS 308 were divided into control (C) and experimental (E) groups with 100 males and 100 females per group. The chickens received the complete feed mixture BR1 from 1 to 10 days of age, followed by the feed mixture BR2 until the age of 30 days, and the feed mixture BR3 until the end of the experiment (40 days). The feed mixtures of the experimental group were supplemented with clinoptilolite (commercial additive ZeoFeed) at a level of 0.5% (BR1), 1.5% (BR2) and 2.5% (BR3), replacing the corresponding portion of wheat. Feed mixtures and drinking water were provided ad libitum. The live weight of broiler chickens in both the control and experimental group increased steadily during the experiment. At the end of the experiment, live weights of experimental females (2,416 g) and males (2,829 g) were higher than those of control females (2,345 g) and males (2,694 g) by 3% and 5%, respectively. Significant differences in the live weight between groups were found from the age of 30 days (P ⪬ 0.05 and P ⪬ 0.01). At the age of 40 days, the chickens were slaughtered and the femur and tibiotarsus of the right leg were analysed for the content of dry matter, ash, calcium, phosphorus and magnesium. The ash content in dry matter ranged from 53.0 to 54.1% in group C and from 51.7 to 53.2% in group E. The Ca and P contents in dry matter in group E were lower than those in group C, except for Ca and P in the male tibiotarsus. In both groups, regardless of sex, the ash content was higher in the tibiotarsus than in the femur. Since fat levels in bones of the experimental group were increased (females by 19.5% in the femur and 21.3% in the tibiotarsus; males by 22.0% in the femur and 26.3% in the tibiotarsus), which could affect the values obtained, ash, calcium, phosphorus and magnesium were determined in the fat-free dry matter. The trends found in the originally determined dry matter were maintained, i.e. lower levels of ash, Ca, and P in the experimental group, except for male Ca in both kinds of bones. The corresponding levels in the fat-free dry matter were relatively higher as compared to the original dry matter. The results of the study showed that up to 2.5% of clinoptilolite in the diet had no adverse effect on performance and bone metabolism indicators of growing broiler chickens. Thus, it can be used as a suitable feed additive to broiler diets due to its positive effect on nutrient utilization, mechanism of digestion and pollutant elimination in connection with food safety issues.

Research has been carried out to study the influence of "ProBioKorm Uz", a biologically active feed additive, on the development and physiological characteristics of rabbits of ‘New Zealand’ breed. During the experiment, 2 experimental and a control groups were formed. Adding "ProBioKorm Uz" to the main feed at the rate of 1% and 2% had an increase in experimental group rabbits’ live weight. Average live weight of them was higher by 5,7 %-3.8% than in the control group. Feed units composed 1.59%, dry matter 0.56 kg (3.61%) and crude protein 0.11 kg (3.59%) compared with the control group. Rabbits of experimental groups had higher indicators of erythrocytes concentration by 0.34-1.00 1012/l (10.34-19.53%), leukocytes - by 0.370-0.46 109/l (5.66-8, 06%), as well as a high level of hemoglobin by 7.42-11.08 g/l (6.81-10.08%) and total protein - by 2.40-4.48 (3.64-6, 42%).

Digestive Organs

The authors studied the growth characteristics (morphophysiological indicators) of broilers’ digestive organs when using Pharmatan in the diet at doses of 0.025; 0.05 and 0.075%. For the study, three medium-weight broiler chickens were selected – on a daily basis for the first three days, then on a weekly basis. The mass of the stomach, individual intestines, the mass of internal organs, and the coefficient of growth rate were determined according to Brody. To study the relative growth rate, the simple allometry formula y = axb was used. It has been established that the most intensive growth of the digestive organs is observed in the first week of broiler life and consists in the stimulated growth of the intestine, especially the cecum. Later on, the growth of the digestive organs in birds of the control group increases and becomes equal to or higher than in broilers of the experimental group. In general, for 42 days of the experiment, the growth rate of the organs of the gastrointestinal tract is practically the same in the birds of the experimental and control groups. The parameters of the regression equations indicate significant differences in the growth of individual organs of the digestive tube during the individual development of broilers. In the experimental groups of broilers, almost all intestinal organs grow quite intensively (b = 1.325–1.783) during the first week of raising, with relatively low values of determination coefficients (cecum – R2 = 0.355; jejunum – R2 = 0.745). High morphological values of 7-day-old birds treated with Pharmatan form the basis for growing broilers with a higher live weight.

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.%.

Цель научно-исследовательской работы – стимуляция продуктивности цыплят-бройлеров кросса «Росс-308» органическими кислотами без снижения питательности рациона птицы. Научно-производственный опыт проводился в условиях ОАО «Витебская бройлерная птицефабрика» Витебской области. Цыплятам-бройлерам кросса «Росс-308» в систему поения, через дозатор ветеринарных препаратов, с водой вводилась жидкая кормовая добавка на основе фульвокислоты (концентрация – 1 г/л ДВ). Исследования показали, что использование органических кислот при выращивании молодняка птицы способствовало активизации неспецифического иммунитета, увеличению сохранности поголовья и повышению мясных качеств цыплят-бройлеров кросса «Росс-308». Так, наблюдалось увеличение средней живой массы птицы к убойному возрасту в опытной группе по сравнению с контролем на 0,8%. От опытной группы птицы было получено на 0,6% (+416 шт.) товарных тушек больше, чем от птицы, выращиваемой в контрольном птичнике. В опытном птичнике было получено тушек I сорта на 0,7 процентных пунктов больше, чем в контрольном птичнике. Соответственно, тушек II сорта было в опытном птичнике получено меньше, по сравнению с контролем. Получение несортовых тушек отмечено не было, так как согласно технологическим правилам предприятия некондиционная птица еженедельно выбраковывается. В совокупности все достигнутые результаты позволили получить весомое увеличение валового производства мяса птицы и дополнительную прибыль для предприятия. The purpose of the research work is to stimulate the productivity of Ross-308 cross broiler chickens with organic acids without reducing the nutritional value of the poultry diet. Scientific and production trial was carried out in the conditions of OAO Vitebsk Broiler Poultry Farm in the Vitebsk Region. Broiler chickens of the Ross-308 cross were introduced into the drinking system through a veterinary drug dispenser, with water a liquid feed additive based on fulvic acid (concentration – 1 g/l AD). Researches have shown that the use of organic acids in the growing of young poultry contributed to the activation of non-specific immunity, an increase in the safety of the livestock and an increase in the meat qualities of Ross-308 cross broiler chickens. Thus, there was an increase in the average live weight gain of poultry by slaughter age in the experimental group compared with the control by 0.8%. From the experimental group of poultry 0.6% (+416 pcs.) more marketable birds were received than from poultry grown in the control poultry house. In the experimental poultry house, birds of 1st class were obtained 0.7 percentage points more than in the control poultry house. Accordingly, birds of 2ndclass were obtained in the experimental poultry house less than in the control. The receiving of grade-out birds was not noted, since according to the technological rules of the enterprise, an off-grade poultry is rejected weekly. For a total all the results achieved made it possible to get a significant increase in the gross production of poultry meat and additional profit for the enterprise.

It is the fact with the introduction of the detailed system of normalized feeding in the livestock industry, the productivity of farm animals has increased by 11,2 %. The obvious solution to the problem of feeding pigs with complete feed is seen in the use of feed and feed additives of local production, which will reduce the final prime cost of the product. The purpose of the work was to justify the use of feed additives Nabikat and Glauconite in feeding sows. During the experiment 3 groups of sows have been formed (a control group and two experimental ones). Sows of the control group have been received the main farm diet, sows of the 1st experimental group in addition to the main diet have been received the feed additive Nabikat (0,20 % of the dry matter of the diet), and the 2nd experimental group Glauconite (0,25 % of the dry matter of the diet). It has been found on the base of researches that the input of the feed additive Nabikat in the diet of pregnant sows has increased the prolificacy of sows by 16,3 %, the livability of piglets by 10,9 %, while the expenditures of feed has been reduced by 20,4 %. The lowest feed and digestible protein expenditures per live weight gain of a pregnant sow and a weaning piglet have been observed in the 1st experimental group when the feed additive Nabikat was included in the diet of sows. The highest feed payment for 1 weaned piglet has been observed when feeding the feed additive Nabikat to sows, which allows producing 24,3 heads of piglets in natural terms, in monetary terms of 1,92 heads. At the same time, it is possible to get an additional profit of 6,9 thousand rubles.

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 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.

The studies were carried out in the conditions of ZAO PPF “Kavkaz” of the Krasnodar Territory. The article presents results of studies on separate and combined usage of active coal feed additive (ACFA) as a sorbent and “Sporothermin” probiotic for development of muscles and internal organs of broiler chickens of “Cobb-500” cross. The studies were carried out in accordance with the “Methodology for conducting scientific and industrial research on agricultural poultry.” At the end of the experimental period, the development of the muscles and internal organs of the bird was studied. In the course of the experiment, the survivability of the bird, the increase of live weight, and the cost of feed were also determined. As a result of the studies, it was revealed that the use of a probiotic and a sorbent increases the live weight of an un-gutted carcass by 5.0-8.7%. With the combined application of a sorbent and a probiotic, the mass of the glandular stomach was significantly increased by 0.15 abs. % (P <0.001). Intestinal mass significantly grew up with application of ACFA sorbent by 0.42 abs. % (p <0.05). Intestinal length evidently decreased by 8.5% (p <0.001) when using “Sporothermine” probiotic. It should be noted that the mass of the thigh muscles significantly increased by 29.0% (p <0.05) in the second experimental group with usage of ACFA, in relation to the control. At the end of the experiment, the live weight of poultry increased by 4.2% (p <0.01) in the second group with ACFA application. In the third group, where “Sporothermin” was used, the live weight grew up by 9.0% (p <0.001). In the fourth experimental group, which was fed with both the sorbent and the probiotic, the best results were obtained and the live weight significantly increased by 9.7% (p <0.001). Over the entire experiment period, feed costs per unit of production have been reduced by 4.3- 8.6%. The survivability of the poultry population was 94.4% in the control. In the second and third groups, the survival rate was also high and exceeded the control by 3.0%, in the fourth - by 5.6%.
