   In recent years, the use of adsorbent and antioxidant preparations in the formulation of feed with a high content of heavy metals is a promising direction in the industrial production of broiler meat. The study aims to study the consumer and hygienic properties of broiler meat when including adsorbent Ferrotsin and antioxidant Selenopyran in diets with high heavy metals and aflatoxin B 1 content. The authors experimentally established the necessity of containing the adsorbent Ferrotsin in the dose of 300 g/t feed and the antioxidant Selenopyran in the quantity of 300 g/t feed into the composition of mixed fodder with excessive concentration of heavy metals. This inclusion of adsorbents and antioxidants in the compound feed composition is necessary to increase the nutritional properties and protective properties of poultry meat. Group 3 broiler chickens significantly exceeded (P < 0.05) the control counterparts by 18.88 % by weight of half-gutted carcass and 18.26 % by weight of the gutted carcass. Also, broiler chickens of the 3rd experimental group exceeded the content of solids in the thoracic and thigh muscles by 1,40 and 0,60, and protein by 0,67 % and 0,67 %. Group 3 broilers significantly (P < 0.05) exceeded the control in protein quality index (PQI) of meat by 18.86 %. In broilers of experimental group 3, there was a reliable (P < 0.05) decrease in the level of zinc by 3.07, cadmium by 2.25 and lead by 3.24 times in the samples of breast muscle relative to the control counterparts. The highest final score was obtained by boiled white poultry meat of the 3rd experimental group. This sample of meat reliably (P < 0.05) exceeded the total sum of organoleptic parameters of the control sample by 0.81 points. In broilers of experimental group 3 in examples of breast, thigh muscles and meat homogenate, the level of selenium was significantly higher than in control due to the presence of this substance in Selenopyran.

Induced Changes

During growth period of 6 to 7 weeks, broiler chickens are exposed to different stressors, the effects of which are dependent on the type, duration and intensity of stress that affects the bird. Stress-induced changes in muscular metabolism alter the physico-chemical traits of meat, thus affecting its quality (Ali et al., 1999). The negative effect of ante-mortem thermal stress on the quality of broiler meat has been the object of many studies and is relatively well documented (Warriss et al., 1999). There is a scarcity of data on whether and to what degree hyperthermia in growing chickens affects the technological parameters of poultry meat. Therefore we carried out an experiment to determine the effect of 5-day heat stress in 4-week-old broiler chickens on their later meat quality.

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.

The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the experimental group than in the control group (p < 0.05). However, drip, cook and thaw losses were not influenced by dietary treatment (p > 0.05). A significant increase in protein, Fe, Zn, Na, P and a significant decrease in lipid, Cu and Cr contents was exhibited in experimental group relative to control group (p < 0.05). The proportion of stearic acid and saturated fatty acids was significantly (p < 0.05) reduced, whereas linoleic acid and polyunsaturated fatty acids contents were significantly (p < 0.05) increased in breast and thigh muscles of fed the experimental diet. We concluded that additive supplementation of the diet with probiotics and Yucca schidigera extract could improve meat quality.

In order to increase the meat productivity of poultry scientists around the all world are working to improve the breeding traits and technologies of housing and feeding. However, the efficiency of poultry meat production on an industrial basis depends not only on the strengthening and inheritance of breed qualities, but also on a complete and balanced feeding, including the use of new feed additives. All this generally affects the duration of rearing, the average daily and absolute live weight gains, the biological value and nutritional value of poultry meat produced in industrial conditions. The purpose of the work was to study the effect of the amino acid complex and silicon dioxide on the productivity and quality of broiler chicken meat. The paper scientifi cally substantiates and experimentally proves the effectiveness of using a rational dose of ultrafine silicon dioxide (300 mg/kg of feed) and the complex of amino acids (arginine – 7 g/kg, lysine – 6 g/kg, methionine – 2 g/kg) in the rearing of broiler chickens. Data on the positive influence of the studied factor on the consumption, digestibility and use of feed nutrients, as well as meat productivity and quality of broiler chicken meat have been obtained. The dependence of meat productivity and quality of chicken meat on physiological and biochemical parameters has been proved. Analysis of the results of the production experiment has been shown that the livability of poultry in the experimental group was higher than the control group by 1,4 %. This made it possible to reduce feed consumption to 100 g/head, and feed consumption per 1 kg of chicken growth in the experimental group by 9,2 %. Activation of metabolic processes of the body of broiler chickens of the experimental group contributed to the increase in their live weight, which increased the weight of the gutted carcass, the yield of meat by 13,8 %, and meat with off al for sale by 18,0 %. The efficiency of the complex application of amino acids and silicon dioxide in the production of poultry meat is economically justified.

The poultry industry in Russia has significant prospects for the development of domestic production of eggs and poultry meat. Insufficient attention is paid to the practical application of enzyme drugs, although numerous studies have proven the effectiveness of these substances in feeding animals and poultry. The purpose of the research was to determine the feasibility and effectiveness of using the multi-enzyme drug Axtra XAP 101 produced by DuPont as part of compound feed for growing broiler chickens. A scientific and economic experiment has been carried out and various doses of the multi-enzyme drug Axtra XAP 101 have been experimentally studied as part of compound feed and the optimal dose in the amount of 7–9 % of the dry matter of the compound feed has been identified. Multi-enzyme drug Axtra XAP 101 influences on indices of meat productivity of broiler chickens. It has been found that this drug increases the average daily increase in live weight of broiler chickens, reduces feed conversion and has a positive effect on the livability of livestock. The highest value for livestock livability has been observed in the 3rd experimental group, where it was 97,67 %, which was by 0,32 % higher than in the control group, by 0,5 % higher than in the 1st experimental group and by 0,57 % higher than in the 2nd experimental group. The European productivity index was the highest in the 3rd experimental group and amounted to 412 points. This indicator was higher than in other groups: higher than the control group by 20 points, the 1st experimental group – by 12 points, the 2nd experimental group – by 5 points. Thus, the effect of using enzymes in wheat and barley diets is to increase and equalize the nutritional value of different varieties and batches of grain. Changing the location and mechanism of microbial fermentation as a result of adding an enzyme also has a positive effect on the health of poultry.

To reduce the risk of aflatoxicosis, antioxidants have proven to be effective feed additives in combination with adsorbents as excellent inhibitors of intoxication processes in the poultry body. The study purpose was to determine the effect of Tox-O adsorbent in combination with Oxy-Nil antioxidant drug on the broiler meat production and quality and reduce the risk of aflatoxicosis. It was demonstrated that to optimize meat production in the diets of farmed poultry with a tolerant amount of B1 aflatoxin, it is necessary to introduce Oxy-Nil antioxidant in the amount of 600 g/t and Tox-O adsorbent in the amount of 750 g/t of feed. Due to synergistic effect of these drugs, the nutritional value of poultry meat was optimized, which was expressed in control group comparison in the enrichment of pectoral muscle samples with dry matter and protein. When feeding tested drugs in pectoral muscle samples of chickens of experimental group III, the value of meat biological usefulness was improved.

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.

For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

This research has been carried out to determine the effects of the current misinformation (hormone, antibiotic, feed additives and growth of broiler chickens in a short period) on consumers' view of the poultry meat sector. The survey was conducted in Istanbul province which better reflects the socio-cultural and socio-economic structure of Turkey, and with different demographic structure of 384 people face to face survey method was applied. Questions were asked to determine whether antibiotics and hormones were used in the diet of broiler chickens, and consumers' perceptions, attitudes and behaviors about the reliability of chicken meat. According to the results of the study, 73.4% of the consumers stated that they did not know about the contents of broiler diets. A big majority of the consumers (88.3%) stated that they think hormone is used and 84.6% think antibiotics is used in the feeding of broiler chickens. 78.4% of consumers surveyed stated that they think that broiler chickens are not fed with healthy feed. Also, 70.6% of consumers stated that rapid growth was due to use of antibiotics and hormones. Although the use of hormones and antibiotics as growth promoters in poultry feeds is prohibited, consumers think that they are used as additives and broiler meat is not safe food. According to these results, creating a positive effect on the purchasing decisions of the consumers is important for the sustainability and future of the sector.

Abstract The issues of development and implementation of resource-saving technologies in broiler poultry farming have a complex purposefulness and their solution must be scientifically substantiated and cost-effective. The productive qualities of meat chickens and broiler chickens of the productive crosses are significantly influenced by many factors that make up the conditions of keeping and feeding. The use of Apex and Emicidin preparations both separately and in combination with each other when rearing chickens of the broiler parent flock of the Ross 308 cross had a positive effect on their productivity and the quality of hatching eggs obtained at the end of the productive period, at the age of 52 weeks. Egg production per initial hen exceeded that in the control group by 2.6% in experimental group 1 (Emicidin), by 3.2% in experimental group 2 (Apex 3010), and by 5.8% in experimental group 3 (combined use of Emicidin and Apex 3010). The determined zootechnical indicators showed high efficiency of the use of the GerbaStor preparation for the floor rearing of broiler chickens of the Ross-308 cross in conditions of increased stocking density in winter. The difference in the productivity index was 18 units, and in meat yield from 1 m² of floor, it was 1.37 kg (3.8%) in favor of the broilers of the experimental group 2, who received GerbaStor. The profitability of the production and sale of meat of broilers grown under an increased stocking density using the GerbaStor preparation was 3.95% higher than that of broilers in the control group.
