Стаття присвячена вивченню можливості вирощування курчат-бройлерів органічним способом для отримання якісної та безпечної курятини. Здійснено порівняння процесу вирощування, динаміки набору живої маси курчат органічного вирощування з традиційною інтенсивною технологією. Акцентовано висвітлено питання зміни біохімічних та морфологічних показників периферичної крові в динаміці. Проведеними дослідженнями патологічних відхилень у картині крові курчат різного віку не виявлено. Певні коливання відповідали віковим періодам росту й розвитку, а також деякому впливу стрес-факторів зовнішнього середовища. Гуманна складова органічного вирощування курей перекриває економічні видатки, пов’язані з більш тривалим періодом утримання, а органічна продукція має додану вартість. Однак лише створення належних умов утримання і догляду птиці для задоволення їх природних потреб, годівля натуральними, екологічно чистими кормами в кінцевому результаті дозволяє отримати якісну й безпечну органічну продукцію. The article is devoted to the study of the possibility of growing broiler-chickens in an organic way to produce high-quality and safe chicken. The growing process, the dynamics of a set of live weight of organic growing chickens are compared with the traditional intensive technology. Organic foods are healthier for consumers than traditional ones. The productivity, well-being and health of farm animals depend not only on feeding, but also on the conditions of maintenance and care. The hematological research promotes the study of the influence of a certain factor on the mechanisms of regulation of metabolic homeostasis of the internal environment of the organism and the productivity of the poultry. The issues of changes in the biochemical and morphological parameters of peripheral blood over time are highlighted. Studies have not revealed  pathological abnormalities in the blood picture of chickens of different ages. Some fluctuations in blood glucose, as well as protein and hemoglobin, respectively, in most control points corresponded to age periods of growth and development, but also some influence of environmental stress factors (elevated air temperature) was noted. The dynamics of oscillations of blood cells was within the physiological norm for chickens of slowly growing breeds. Significant deviations testifying the violation of the health status of the poultry were not established. The humane component of organic chicken raising covers the economic costs associated with a longer period of keeping and organic products have added value. However, only with the creation of proper conditions for the maintenance and care of poultry to meet their natural needs, when feeding with natural, environmentally friendly feed – you can ultimately receive high-quality and safe organic products.

Abstract. The experiment was performed with a total of 180 day-old, ROSS 308 combination, meat-type hybrid chickens that were divided according to sex into the control group (C1 and C2 with 30♀ and 30♂, respectively) and two experimental groups: GLY-P1 and P2 with pure glycerol (30♀ and 30♂), and GLY-R1 and R2 with raw glycerol (30♀ and 30♂). The chickens received three feeding mixtures during the experiment: the pre-fattening mixture (BR 1) until Day 14, the fattening mixture (BR 2) from Day 15 to Day 30, and the post-fattening mixture from Day 31 to Day 40 (BR 3). 50 % of the soybean oil in feeding mixtures used in the experimental groups (GLY-P and GLY-R) was replaced with pure or raw glycerol at a ratio of 1:2. The feed and water were available ad libitum for consumption. The mean live weight of both male and female chickens in experimental groups on Days 15 and 40 was statistically significantly higher (P≤0.05, P≤0.01) than that in the control group. The consumption of the feeding mixture during the entire 40-day fattening period was higher in female and male chickens in experimental groups. The differences in the mean weight of processed carcass between the control and experimental groups were very significant (P≤0.01). Glycerol obtained during rapeseed processing is a suitable source of energy and can be added in feeds designed for farm animals.

Abstract At present, modern high-yielding crosses of broiler chickens are used to produce high-quality meat with high technological and consumer properties. To assess the meat productivity of broiler chickens grown on fodder produced in the conditions of the poultry factory at our own feed factory, a control slaughter was carried out at the age of 42 days. Analysis of the data obtained shows that with an average poultry live weight of 2000 ± 50 g, the slaughter yield of broiler chickens was 71.8 ± 0.13%. At the control slaughter, we found that the weight of the gutted carcass was 75.23%, offal 10.32%, and technical waste 14.45% (Figure 1).When studying the quantitative and qualitative composition of by-products, we found that liver accounted for 18.42%, stomachs 7.47%, heart 3.39%, neck 12.59%, legs 33.9%, heads 24.23 % by weight of offal.In the structure of technical waste feather is 24.92%, blood is 32.87%, intestine is 42.21% (Figure 3).Thus, the results of our research show that when cutting broiler chickens grown on self-made feeds under the conditions of modern poultry enterprises with a closed production cycle, gutted carcass weight is 75.23%, while legs and heads constitute the main bulk of the mass of by-products.

AbstractThere is varying understanding about life for farm animals. The majority of farm animals have gone from the land, only to be caged, crammed and confined behind the closed doors of the factory farm — battery hens sentenced to remain for life in wire cages, broiler chickens reared in overcrowded conditions and pigs tethered and confined in narrow stalls or in equally narrow farrowing crates. Other farm animals are sent abroad to the cruel veal crate system of continental Europe or to abattoirs where welfare standards, both during transportation and at the time of slaughter, are often appallingly low. Many of the animals slaughtered in Britain, or for the live export trade, are processed through live auction markets. A recent investigation revealed many instances of infringements of the regulations governing the treatment and welfare of animals at markets. The controversy over BSE and the cloning and genetic engineering of farm animals have all resulted in close scrutiny and inquisitions by the public into the conditions in which our farm animals are reared, treated and slaughtered. Those involved in the food industry and also those who care about the welfare of animals and recognize their sentiency must take action to ensure that the animals are reared with due thought to their behavioural needs and well being and, when the time comes, granted a quiet and humane death. For far too long in food production programmes farm animals have paid a heavy price in suffering. From birth to death, farm animals must be treated humanely and with respect.

Scientific studies of foreign and domestic scientists convincingly proved that selenium is a vitally necessary trace element for farm animals and birds with a wide range of biological effects. It performs unique multifunctional functions in the body – structural, catalytic, regulatory, possesses antioxidant, anti-carcinogenic radioprotective, immunostimulant, antiviral, anti-mutagenic, anti-toxic and adaptogenic properties, participates in the formation of mechanisms that determine the reproductive function of animals and birds, affects osteogenesis, participates in the processes of growth and development. In the scientific and economic research the influence of additives of various doses of selenium into mixed fodder on the development of the digestive system in broiler chickens was studied. As a source of selenium, selenite sodium was used. The research was conducted in the production conditions on broiler chickens of the COOB 500 cross. The duration of the experiment corresponded to the period of growing the young for meat and was 42 days. It was established that the use of selenium in the composition of mixed fodder for broiler chickens at doses of 0.3; 0.4 and 0.5 mg/kg positively influenced the development of the digestive system in young, in particular, contributed to an increase in the mass (by 4.1–11.6%) and total length (1.3–3.5%) of the intestine in general, and its thin and thick parts in particular, as well as the mass of the muscular stomach (17.3–23.2%) and liver (3.6–10.0%). The best macromorphological parameters of the digestive system development were chicken broilers, which, during the entire period of growing, mixed fodder, were enriched with selenium at a rate of 0.3 mg/kg. Comparison of the live weight of broiler chickens of experimental groups with indicators of intestinal development, muscular stomach and liver allows us to assume that the digestive systems in them have been developed better and during the growing period they function more actively.

The paper presents the results of the effectiveness of anti-stress therapy and its economic assessment when growing broiler chickens in a poultry farming against the background of the use of a stress-protector antioxidant-complex (SPAO-complex) in broiler chickens. The pharmacological complex was used in the form of a drink at a dose of 185 mg/kg of live weight for 5 days during periods of the greatest influence of stress factors, namely at the stage of vaccination associated with the greatest immunological load (at 10-14 days of age) and (or) at the stage of final fattening. The effectiveness of antistress therapy was assessed by the morphological parameters of poultry blood, leukocyte indices, the yield of poultry meat and the quality of carcasses. The economic efficiency was assessed by the ratio of the economic effect and veterinary costs. A relative decrease in the total level of leukocytes and a change in leukocytes of different types was found: a decrease in agranulocytes and an increase in agranulocytes, a decrease in the value of the Krebs index, the leukocyte index of intoxication, an increase in the lymphocyte index, the ratio of agranulocytes and granulocytes and lymphocyte-granulocyte index. The use of the SPAO-complex in broiler chickens in the form of a drink at a dose of 185 mg/kg of live weight for 5 days due to the growth rate and an increase in live weight helped to reduce the impact of stress factors and led to an increase in meat yield by 2.34-4.92% and a decrease in injuries before slaughter, which was reflected in a decrease in the level of carcass defect from 20-40%. It influenced the value of the economic effect which amounted to 70.08-145.2 rubles. The value of veterinary costs for different anti-stress therapy regimens ranged from 9.35 to 101.32 rubles. The economic efficiency of using the SPAO-complex at a dose of 185 mg/kg of live weight per day for 5 days per one ruble of costs during the period of intensive vaccination was 16.7 rubles, during the period of final fattening it was 0.81 rubles and during periods of intensive vaccination and final fattening it was 1.52 rubles.

The necessity has been widely noted of improving the nutritional value of forage mixtures used in the poultry industry through the use of enzyme preparations on the basis of phytase for splitting phytic acid and its salts contained in the feed. This technological approach is relevant in feeding farm animals, particularly poultry, as they are unable to synthesise endogenous phytase. On the base of the Agro-Industrial Complex "Oril-Leader" we researched the influence of the enzyme preparation Ladozim Proxy as a feed component for broiler chickens and laying hens on the growth and biochemical parameters of the birds and their egg-laying capacity. The feed ration consisted of wheat, corn, sunflower meal, extruded soy and protein-vitamin complex Biomix. For the research experimental and control groups of broiler chickens were formed (50 birds in each group) and laying hens (20 birds in each group). The experimental feeding period was 35 days for the chickens and 30 days for the hens. The research used physical-chemical methods for determining the content of nitrogen, calcium and phosphorus in the feed, the blood and the excrement of the birds. Statistical data processing was carried out by ANOVA. It was established that the use of Ladozim Proxy in the amount of 60–100 mg/kg feed promotes an increase of the live weight of chickens by 21%. The findings can be explained by an increase of the feed nutrients available for digestion in the gastrointestinal tracts of the poultry due to the hydrolytic action of the enzyme complex added to the phytic-containing components of the feed. The result of these phenomena is also a positive dynamic in assimilation of nitrogen, calcium and phosphorus in the feed by chickens of the experimental group: use of these elements increased by 10–16%. The preparation had no effect on hematological indices of the organisms of the poultry and increased the amount of calcium and phosphorus in the blood. The use of the preparation has not only physiological, but also economic importance because it allows a reduction in feed intake and expenditure on feed for poultry reared for agricultural production. The use of the phytase preparation does not affect the quantitative indicators of egg-laying by hens, but an increase in the thickness of the egg shells was noted, due to deposition of calcium in the organism of the experimental group.

Unbalanced nutrition as well as diseases of infectious and non-infectious etiology lead to a decrease in production and a significant loss of farm animals and birds. To mitigate these problems, various probiotic drugs (probiotics) are introduced into the diets of birds and animals for preventive purposes. The aim of the research was to study the effect of the Vitafort probiotic, containing antagonistic bacteria of the endophytic strain Bacillus subtilis B11, on the body of broiler chickens. The effect of Vitafort was assessed by measuring the live weight and average daily growth of birds. In addition, a morphological study of blood was carried out and the content of Bacillus subtilis in the small intestine was determined. It was found that the endophytic strain Bacillus subtilis B11 improved the intestinal microflora. Thus, on day 5 of its use, the number of microorganisms varied from 4.1 × 104 to 8.2 × 104 CFU/g, and on day 42 the same number varied from 4 × 108 to 5.8 × 108 CFU/g on day 42, the contents of red blood cells, haemoglobin, and white blood cells in the blood of chickens from the experimental group were higher by 6.44%, 3.44%, and 2.11%, respectively, than they were in the control group. Considering the above facts, it can be assumed that the absorption of nutrients in the intestine improved, and metabolic processes were activated due to an increase in the transport abilities of red blood cells.

Abstract The purpose of this study was to compare a continuous lighting programme (23 hours of lighting (L) / 1 hour of darkness (D)) with intermittent lighting programmes (16L: 8D) and also to investigate the effects of the length of the dark cycle in the intermittent programme on the performance, carcass characteristics, water consumption, uniformity, metabolic parameters, and ammonia burns of chickens. Thus, five hundred Ross-308 male chicks were used. The 23L:1D was applied to the chicks for 7 days. On day 7, they were divided into four groups by balancing their live weight; group I: continuous 23L: 1D; group II: intermittent 4x (4L: 2D); group III: intermittent 2x (8L: 4D); group IV: continuous 16L: 8D. The study took place between days 7 and 42. At the end of the study, 10 chickens from each group were slaughtered, their carcass, blood, and bone properties were analysed. Body temperatures and ammonia burns were assessed for all broiler chickens. The mean live weight of group IV was the lowest. The difference among the groups in terms of live weight gains, feed intakes, feed conversion ratios, and survival rates was non-significant. Long-period darkness in group IV significantly dropped the water consumption. On day 21, group III’s best uniformity was calculated; but on day 42, the difference was non-significant. The highest breast ratio and the lowest wing ratio beloged to chicks in group I. Their free T4, glucose, and uric acid levels were lower; whilst their testosterone levels were higher. Body temperature and tibia ash levels were similar across all of the groups. The intermittent lighting programmes increased the number of ammonia burns. Consequently, the long-term darkness negatively affected both the chickens’ performance and well-being.

Abstract. To advance knowledge of the mechanisms underlying the relationship between leadership and employees’ well-being, this study examines leaders’ effects on their employees’ compensatory coping efforts. Using an extension of the job demands–resources model, we propose that high-quality leader–member exchange (LMX) allows employees to cope with high job demands without increasing their effort expenditure through the extension of working hours. Data analyses ( N = 356) revealed that LMX buffers the effect of quantitative demands on the extension of working hours such that the indirect effect of quantitative demands on emotional exhaustion is only significant at low and average levels of LMX. This study indicates that integrating leadership with employees’ coping efforts into a unifying model contributes to understanding how leadership is related to employees’ well-being. The notion that leaders can affect their employees’ use of compensatory coping efforts that detract from well-being offers promising approaches to the promotion of workplace health.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.
