The analysis of different doses of complex feed additive to poultry ration have been made. The influence of new feed additive with bioresources of the Far East use on productive poultry indexes, on production quality and digestibility of nutritious matters of mixed feed has been studied. Patrinia scabiosifolia, Acanthopanax sesseliflorum, cones of cedare nut husk, brown seaweed, macro- and microelements, vitamins were the object of research. As a result of these researches author presents more effective norms of complex feed additive use in poultry farming of Khabarovsk Kray. The recipe of feed additive from local vegetable resources and complex of vitamins and minerals for use in laying hens nutrition was worked out. The aim of this work was to rise zootechnic and economic indexes of poultry production. The introduction of complex feed additive in ration influenced positively on the digestibility, raised the content of Omega-3 fat acid in egg of laying hens. The increase of Omega-3 fat acid quantity promotes decrease of cholesterol in yolk of egg. In the experimental groups there was a more intensive use of nutrients in diet, mainly due to raw protein, fats, mineral substances – calcium and phosphorus. The use of a new feed additive had a positive effect on the hatchability of eggs, the development of internal organs (heart, liver) and the live weight of chicks obtained from the eggs of chickens in experimental groups. Additionally, the content of mineral substances (calcium, potassium, phosphorus) in the egg of test group was higher than in the control on average by 2.3-5.1%.

This paper presents a study of the effect of the feed additive «Abiotonic» on the indicators of egg and meat productivity when applied to laying hens. It was found that with the additional introduction of this additive into the standard diet of poultry, the content of nonessential amino acids in their meat is 10% higher compared to the same parameters in the meat of chickens of the control group, the content of partially nonessential amino acids is by 8,5%, and of irreplaceable amino acids is by 6,7%. In addition, in the meat of laying hens, which used the feed additive «Abiotonic», the content of selenium (Se) is 29,4% higher than in the meat of birds of the control group, and iron (Fe) – by 20%. The average daily gain in live weight of the birds in the experimental group was 3,6 g more than in the control hens. Microbiological research made it possible to establish that poultry meat, regardless of the introduction of the feed additive «Abiotonik», meets the established requirements and is safe for human consumption. «Abiotonic», in addition, significantly improves the egg production of birds. It was found that the weight of eggs with the introduction of this feed additive in the diet in addition to the compound feed increased by an average of 1,2 g, and the egg production increased by 23 eggs in 7 days.

The possibilities of increasing the productivity of different poultry species by increasing the absorption of feed nutrients can be realized through the use of new biologically active components that are usually added to traditional feed based on live cultures of microorganisms of the normal microflora of the gastrointestinal tract. The effectiveness of different probiotic drugs varies depending on the types and strains of microorganisms that are included in their composition, the dose of the drug, the scheme of its use, age, type, physiological state and productivity of animals. The research has been carried out to study the influence of the use of the probiotic feed additive Amilocin in the diets of laying hens of the cross Hisex Brown on their productivity. The positive influence of the studied feed additive on the live weight and livability of laying hens, egg productivity, quality and quantity of eggs obtained, morphological and biochemical parameters of the blood of experimental poultry, slaughter parameters and chemical composition of the meat of experimental laying hens has been established. The optimal rate of introduction of probiotic feed additive Amilocin into the diet of laying hens has been determined (0,5 g/head/day at the beginning of egg laying during 10 days, 1,0 g/head/day at the peak of egg laying during 10 days, followed by 1 g/head/day monthly for 10 days until the end of egg laying). The economics effectiveness of using the probiotic feed additive Amilocin per 1,0 ruble of costs was 1,24– 1,35 ruble. According to the research data recommendations for the use of the probiotic feed additive Amilocin have been proposed.

Abstract In the era of increased antibiotic resistance and ever stricter control on antibiotic use, it is urgent to develop green, safe and non-residue alternatives to antibiotics applied to the poultry industry. To this end, we supplied the potential Lactobacillus Plantarum (L. Plantarum) fermented Astragalus in the diet of laying hens, with a final addition of 3‰. Its effects have been assessed on laying performance, egg quality, antioxidant and immunological status and intestinal microbiota, and are compared to the control group, to the Astragalus group containing 3‰ unfermented Astragalus, and to the L. Plantarum group containing 2% L. Plantarum (1 × 108 CFU/mL). During the second half of the experimental period (15 to 28 days), the egg production rate was significantly higher in the fermented Astragalus group than that in the other groups, with the fermented Astragalus group having the lowest feed conversion ratio. No significant difference (P > 0.05) was observed among treatments on egg quality. Fermented Astragalus-treated hens exhibited significantly increased catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in serum, and reduced malondialdehyde (MDA) in serum. Furthermore, fermented Astragalus supplementation resulted in a significant increase in ileal microbiota abundance relative to control. In conclusion, feeding laying hens with L. Plantarum fermented Astragalus has beneficial effects on production, antioxidant potential, immunity and ileal microbiota. L. Plantarum fermented Astragalus is expected to be a novel feed additive used in poultry production.

The study aims at investigating the effect of preparations of two bacilli strains on laying hens and roosters. Preparations were based on the strains Bacillus subtilis KATMIRA1933 and Bacillus amyloliquefaciens B-1895. Several groups of roosters and hens received a preparation based on either strain, or a mixture of both, from the first day to the last day of poultry in production. These preparations improved egg production, quality of sperm production, quality/hatchery of eggs, and slowed down the reproductive aging of hens. These observations were confirmed by the mathematical model proposed herein. At the molecular level, the slowing down of aging was confirmed by a decrease in the amount of mitochondrial DNA damage. Monitoring the physiological parameters of the experimental and control groups of birds showed that live weight gain in all experimental groups was higher than in the control group, and the reproductive organs of hens were more developed. There was also an improvement in the biochemical parameters of blood, the quality of the sperm of roosters, the laying of laying hens, and the morphological and biochemical parameters of the eggs. One of the most significant results is an increase in egg fertilization and a decrease in embryo death during the first 7 days of incubation.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

Изучена целесообразность использования в рационах телят черно-пестрой породы комплексной минерально-витаминной кормовой добавки (КМВКД). Установлено пониженное содержание в кормах таких элементов, как кальций, фосфор, магний, сера, марганец, медь, цинк и кобальт. Соотношение питательных и минеральных веществ, степень их доступности для усвоения организмом не обеспечивают их потребность. Использование КМВКД способствовало улучшению всех гематологических показателей. Все испытываемые рецепты, имеющие в своем составе разные варианты макро-, микроэлементов и витаминов положительно влияют на обменные про- цессы в организме животных. У молодняка опытной группы, получавшей подкормку по рецепту 1, количество эритроцитов в сравнении с животными контрольной группы увеличилось на 6,6, гемоглобина на 6,93 соответственно, по рецепту 2 11,05 и 11,39 по рецепту 3 16,75 и 15,27, то есть соотношение макро- и микроэлементов, имеющихся в составе КМВКД и взаимодействие между собой меди, железа и кобальта сыграли особую роль на концентрацию форменных элементов. У молодняка, получавшего подкормку по рецепту 1 количество общего белка в сравнении с животными контрольной группы увеличилось на 1,99, кальция на 16,02, каротина на 10,92 соответственно, по рецепту 2 4,91, 25,96 и 19,12 по рецепту 3 на 3,58, 27,07 и 20,21. Значительное повышение содержания белка, кальция, фосфора и каротина по сравнению с животными контрольной группы объясняется тем, что недостаток их в рационах восполнялся за счет используемой подкормки, в результате их содержание увеличилось в сыворотке, но не выходило за пределы нормативных данных и соответствовало физиологическим нормам.Practicability of using a complex mineral and vitamin feed additive (CMVFA) in the ration of black-and-white calf breed was studied. Decreased content of such elements as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc, and cobalt was registered. The correlation of nutritive and mineral substances, and the level of their availability for digestion did not provide for their need. CMVFA use facilitated the increase of all hematologic parameters. Tested recipes which had different content of sapropel and zeolite, as well as various types of macronutrients, microelements, and vitamins, positively influenced the digestive processes in animal bodies. Young stock from the test group that was receiving food additives according to recipe No. 1 showed 6.6 increase in the quantity of red blood cells compared to control group animals, and 6.93 increase in hemoglobin quantity the ones who were fed according to recipe No. 2 demonstrated the increase by 11.05 and 11.39 recipe No. 3 showed 16.75 and 15.27 increase, which means that the ratio of macronutrients and microelements present in CMVFA and the mutual interaction of copper, iron, and cobalt played a special role in the concentration of formed elements due to the fact that they are integral elements of blood. Total protein of young stock that was receiving food additives according to recipe No. 1 was 1.99 higher than in test group animals calcium 16.02 higher carotene 10.92 as for recipe No. 2 the values were increased by 4.91, 25.96, and 19.12 recipe No. 3 3.58, 27.07, and 20.21. Substantial increase in the content of protein, calcium, phosphorus, and carotene compared to control group animals can be explained by the fact that their insufficiency in animal feed was replenished due to the use of feed additives, and as a result their content increased in the serum but did not go beyond the norm and corresponded to physiological norms.

This study was to investigate the effects of Bacillus subtilis on production performance and bone pathophysiological characteristics of layers. Twenty-four 48-week-old Lohmann Pink-shell laying hens were randomly divided into two groups: a basic diet (control) and the basic diet mixed with Bacillus subtilis (0.5 g/kg) for a 60-day trial. Statistically, independent-sample t-test was used to assess the treatment differences. The results showed that Bacillus subtilis supplementation improved the percent of marketable eggs (p < 0.05) with reduced numbers of broken and soft-shelled eggs but had no effects on egg weight, height of albumen, yolk color, and Haugh unit (p > 0.05). Bacillus subtilis supplement also elevated maximum load (p = 0.06), maximum stress (p = 0.01), stiffness (p < 0.01), and Young’s modulus (p < 0.01) but suppressed maximum strain (p = 0.06) in the femur. In addition, compared with control birds, phosphorous concentration (p < 0.01) was reduced in serum at day 61 but increased in the femur (p < 0.05) in Bacillus subtilis fed birds. Bacillus subtilis fed birds also had lower magnesium concentrations in both femur (p = 0.04) and feces (p = 0.09). Furthermore, Bacillus subtilis increased plasma estrogen concentration (p = 0.01) and femur TNF receptor superfamily member 11b (OPG) expression (p < 0.05) but reduced plasma IL-1 (p < 0.01) and TNF-α (p < 0.01) concentrations. These results indicate that Bacillus subtilis could be used as a health promotor to reduce overproduction-induced inflammation and associated bone damage and to increase marketable egg production. The data provide evidence for developing a management strategy to use Bacillus subtilis as a feed additive to improve marketable egg production and health and welfare status of laying hens.
