Abstract. One of the urgent tasks in modern poultry farming is the search and testing of new, cheap and at the same time environmentally friendly feed additives that positively affect the productivity and health of poultry [1, p. 105]. Such additives include acidifiers, consisting of complexes of organic acids and their salts. The range of organic acids used in our country is large: formic, propionic, acetic, benzoic, butyric, sorbic, fumaric, succinic, citric, ascorbic, tartaric acids and others, as well as their salts [2, p. 81. 3, p. 28. Scientific novelty. In the conditions of the “Amur Broiler” poultry farm, studies were conducted on the effectiveness of using the Acidomyx AFG organic acid. The aim of the research was to determine the rational dosage of the medication based on Acidomyx AFG organic acids, as well as to assess its effect on meat productivity and the livability of broiler chickens. Methodology and research methods. The productive effect of Acidomyx AFG was assessed by the following indicators: live weight at the age of 7, 15, 25, 35, and 41 days old; daily average increase in chickens; livestock livability, feed costs per 1 kg of live weight gain. Results. Studies have shown that the most productive was the use of the studied medication at a dosage of 0.3 % in the starter period, 0.2 % in periods of growth and finish. The effectiveness of the medication turned out to be the best in comparison with the control in terms of live weight by 15.8 %, average daily gain in chickens by 16.1 %, in terms of livestock livability by 8.9 %, and in feed costs per 1 kg of live weight gain by 0.03 kg.

The research (2018-2019) was conducted in the conditions of a peasant farm in the Voronezh region. The paper evaluates the indicators of the growth rate and meat productivity of the preserved gene pool groups of guinea fowl. The experiment involved three groups of daily guinea fowl of 200 heads of different genetic origin: lines of the Volga white breed (the original VB-4, selected by the rate of live weight gain and reproductive characteristics; autosex VBA-1, selected by the color of down, feather and productive characteristics) and gray-speckled guinea fowl of unknown origin. Studies have shown that the live weight of guinea fowl of the VBA-1 line exceeded the live weight of poultry from other groups of guinea fowl, a significant excess was noted at 8, 12 and 13 weeks of age. The greatest coefficient of variation of the trait was observed at 8 weeks of age. The analysis of relative gain in live weight of guinea fowl showed that up to 10 weeks of age, the highest relative growth rate of guinea fowl of all experimental groups was observed (14.0-17.0 %). Starting from the age of 11 weeks, this indicator gradually decreased (4.3-13.4 %). It was found out that under the same conditions of keeping and feeding, the feed costs per 1 kg of live weight gain in guinea fowls of the VBA-1 line were less by 0.09-0.16 kg (3.11-6.33 %) compared to poultry of the VB-4 line and by 0.2-0.4 kg (5.49-12.82 %) compared to their gray-speckled peers. The results of anatomical cutting of guinea fowl carcasses showed that the experimental groups of poultry significantly (P< 0.05) differed among themselves in the degree of development of internal organs and tissues. The yield of edible parts was 60.2-61.1 %, depending on the group of poultry. The large live weight noted by us in linear poultry is the reason for their better meat productivity, which is directly related to an increase in the absolute mass of the eviscerated carcass, its edible parts, muscles and bones. Based on the data obtained, the optimal age of poultry slaughter for meat was determined at 10-12 weeks of life.

Under the environments of the Tyumen region a scientific and research work has been carried out, including an assessment of the influence of antimicrobial substances: colloidal silver, antibiotics and organic acids on the body of broiler chickens. The purpose of the work was to evaluate the influence of antimicrobial substances on the productivity of broiler chickens. The research and laboratory experiment has been carried out in the laboratory of the Northern Trans-Ural Scientific and Research Institute of the Tyumen Scientific Center of Siberian Branch of Russian Academy of Sciences on chickens of the cross ArborAykrs+. Chickens at the daily age have been distributed according to the principle of balanced groups-analogues. The period of chicken rearing was 35 days, during the same period the analysis of the studied antimicrobial substances has been performed. The composition of the test substances was included colloidal silver 10 μg/l, antibiotics (Pulsoceril, Enronite) and the mixture of organic acids (Agrofeed) at the dose of 0,4 ml/l. The results have shown that chickens that have been watered colloidal silver had the gain of live weight for the period of rearing 1850,94 g or lower than chickens in the control group. At the same time, broiler chickens with watering of antibiotics and organic acids exceeded the control group’s analogues. For example chickens of the 1st experimental group where colloidal silver has been watered at the dose of 10 mcg/l every day had the live weight gain during the rearing period lower by 15,56 g and the average daily live weight gain of 0,45 g than chickens of the control group. At the same time broilers of the 2nd experimental group (with antibiotics) and the 3rd experimental group (with organic acids) had the higher gain of live weight during the rearing period by 56,61 and 95,23 g, respectively, compared to the control group. The average daily gain diff erences were 1,62 and 2,72 g. Indicators of morphological and biochemical composition of blood of experimental groups of broiler chickens indicated that they were within the limits of the corresponding physiological norms. At the same time, there were some changes on the part of both red and white blood, which seems to be related not only to the body’s response to feeding, but also to the biochemical processes within the body.

The authors studied productivity and product quality under industrial poultry production technology. The productivity of broiler chickens of Ross-308 and Hubbard Iza-F-15 was different during floor rearing. Broiler chickens of Ross-308 outperformed Iza-F-15 chickens in body weight and average daily gain. The live weight at the slaughter of Ross-308 chickens was 2,360 g. The live weight of the chickens of Iza-F-15 was 2088 g. The conversion of feed to produce was higher in the chickens of Ross-308 cross by 0,06 kg compared with the chickens of Iza-F-15 and amounted to 1.64 kg per 1 kg of live weight gain. The survival rate was high for Ross-308 chickens (95.8%). The safety of the flock of the Izu-F-15 chickens was 2.2 per cent lower and was 93.6 per cent. Slaughter yield in the chickens cross Ross-308 is higher than in the group of chickens cross Iza-F-15. Meat quality is also better in Ross-308 chickens. Growing broiler chickens of Ross-308 cross for meat under industrial technology allowed to get more profit compared to the use of poultry of Iza-F-15 cross. At the exact cost of feed, 1 kg of live weight gain was 7.1 roubles, and per 1 head of chick was 19.1 roubles. The profitability level is also 12.6% higher for the broiler chickens of Ross-308 cross. The cumulative indicator the European productivity index is higher for chickens of Ross-308 breed, compared with chickens of Iza-F-15 breed on 56 units. This index was 341 and 285, respectively.

This study aimed to assess forage production, animal performance, and the chemical composition of Tanzania grass pasture fertilized with 50, 100, 200, and 400 kg ha-1 of nitrogen. The variables analyzed were: leaf mass, daily accumulation rate, leaf/stem ratio, average daily gain, stocking rate, live weight gain per unit of area crude protein, neutral detergent fiber, and in vitro dry matter digestibility of leaves. The pasture management maintained the pasture height at 50 cm by using a continuous grazing method with the adjustment of stocking rate. The experimental design was a randomized block with three replicates. The leaf mass increased linearly in response to nitrogen, with an increase of 1003 kg (34%) observed between a nitrogen content of 50 and 400 kg ha-1. Nitrogen did not affect the average daily gain, but increased the stocking rate and live weight gain ha-1. The value of crude protein and neutral detergent fiber were higher with increased nitrogen levels, whereas the leaf digestibility did not affect nitrogen use. The comparison of 50 and 400 kg ha-1 levels indicated that there was an average increase of 19.2% in the leaf crude protein. The increased application of nitrogen fertilizer in Tanzania grass improved the chemical composition and animal performance; with regard to studied variables, the dose of 200 kg ha-1 resulted in the greatest improvement.

The paper presents the study on an impact of feed additives Peak anti-stress and SPAO (SPAO-complex) with different lithium content on meat productivity and meat quality of broiler chickens. The feed additives exert a pronounced metabolic effect, have adaptogen properties and allow forming a mechanism that facilitates compensation of the expenditure of the body, which significantly increases upon stress development. It was established that the average daily gain of the broiler chickens increased by 1.8% and 4.3% on the background of using SPAO-complex and Peak anti-stress, respectively, compared to the broiler chickens that did not receive the feed additives in the daily diet. It was shown that addition of feed additives with lithium into a diet led to an improvement of the indices of broiler meat productivity and meat quality: a level of yield of the carcasses of the 1st category increased up to 56.2–79.1%, high organoleptic indices of meat were ensured, the protein content in white and red chicken meat increased and functional-technological properties of minced meat improved. The use of feed additives ensured profitability of industrial poultry production; the highest indices of profitability were established upon introduction of the feed additive Peak anti-stress into a diet — up to 8.67 rubles per each ruble of expenses. The obtained results of the study should be taken into consideration in the technological processes when raising broiler chickens.

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.

Abstract The article presents the results of studies conducted on the inclusion of Presan and Selko pH feed additives produced on the basis of organic acids in the feeding diets of Ross-308 cross broiler chickens. Organic acids and their salts are used in poultry farming as an alternative to feed antibiotics, and also has the ability to prevent the development of intestinal bacterial infection, increase the resistance of the body, thereby improving the absorption of feed nutrients and increasing poultry productivity. The largest preslaughter weight was in the groups of cockerels getting the T6 diet without antibiotics adding, which is 1.92% more than the groups getting the T1-control diet. In addition, the output of the pectoral and femoral muscles was higher by chickens getting a T6 diet by 0.5 and 0.3%, in contrast to groups getting a standard diet. Thus, it has been experimentally proven that the tested feed additives Presan and Selko pH do not reduce the slaughter performance of broilers.

Positive Effect

Fodder methionine is one of the most important amino acids in animal nutrition, and its deficiency in the ration negatively affects productivity. Currently, the following sources of methionine are represented on the Russian market of feed additives: DL-Methionine and Methionine Hydroxy. Liquid form — Methionine Hydroxy Analog Free Acid (MHA-FA) and dry (for example, МНA) — calcium salt (MHA-Ca2+). The most popular sources of dry methionine are DL-Methionine and hydroxy analog as calcium salt. Many sources state that the bioavailability of the hydroxy analog varies from 65 to 72% (one of the manufacturers of the commercial hydroxy analog claims that the availability of methionine is 84%). The experiment was carried out on broiler chickens. As a result of the studies carried out, it can be argued that the content of DL-methionine in the ration (in the amount of 65% of the hydroxyanalogue) in comparison with MHA-Ca increases the productivity of broilers: preservation – by 4%; live weight by 4.3%; average daily gains by 4.6%; feed conversion decreased by 7.1%; has a positive effect on meat productivity. Based on the data obtained during the experiment, it follows that the efficiency of MHA-Ca does not exceed 65%, compared to DL-Methionine.
