The experiment was performed in two groups of broiler chickens. The birds from the experimental group were treated with the combination of 3% lactic bacteria. 1% baker's yeasts and 0.7% citric acid, added to food. It was found out that the treatment resulted in shifting the microbial balance in avian gastrointestinal tract in favour of Gram-positive bacteria (77-80%) while in control birds Gram negative organisms prevailed (90%). Both the volume and the weight of viscera of experimental chickens, obtained following slaughtering was by 20-60% higher compared to controls. Furthermore, 75% of treated birds reached a slaughtering weight (1800 g) for 42 days with an average daily weight gain of 57 g and expenditure of 2.3 kg fodder per 1 kg weight gain, whereas the body weight of control birds was by 26.5% lower than the standard one, the fodder expenditure was 3.1 kg per 1 kg weight gain and the average daily gain was 42 g. The mortality in controls was 13% while in treated birds there were no lethal cases. The price of one kilogramme body weight in experimental birds was by 0.15 $ lower compared to controls.

The purpose of the research is increasing the average daily gain of animals due to the use of the Bisolbi drug. The effect of Bisolbi preparation based on Bacillus subtilis H-13 1.5×108 (LLC «Bisolbi-Inter») on the biochemical and productive life of calves was studied. The scientific and production experiment was carried out on the basis of a dairy farm of the State «Kupinskoe» Unitary Enterprise of the Samara region involving 30 Holstein-Friesian calves. The biological effect of the drug is provided due to its adsorption properties, the ability to enhance the activity of a number of enzyme systems and increase the digestive and systemic immunity of the body. The drug use increases the integration intensity of animals: the amount of total protein in the blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p<0.05), albumin – by 9.2% (p<0.01), compared with the animal data of con-trolled group. The Bisolbi indication contributed to an increase in the intensity of carbohydrate-lipoid metabolism: the cholesterol amount was higher by 23% (p<0.01), the glucose content – by 0.4 mmol/l (p<0.05) in the blood of 120 day old calves of the experimental group, compared with the data of controlled animals. It was found that the body weight of calves in the control group of 100 days age was 105.23±2.11 kg, in the experimental group – 108.6±2.19 kg, which is 3.37 kg higher. The average daily weight gain of animals in experimental group was signif-icantly higher by 0.075 kg (p<0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p<0.05), the average daily weight gain by 0.080 kg (p<0.05), compared with the data of the controlled ani-mals. The indication of Bisolbi 5-10 ml (LLC «Bisolbi-Inter») to calves daily for 2 months resulted in an additional profit constructively of 137 rubles from each head.

Aimed to study the effective use of different doses of cuprum proteinate in the diet of broiler chickens, three groups of animals were formed with 50 chicks in each. Chickens from the 1st control group received cuprum sulphate as a part of compound feed, and animals from the 2nd and 3rd experimental groups received cuprum proteinate. The concentration of Cuprum in the feed in the 1st and 2nd groups was identical, and in the 3rd experimental group the amount of Cuprum was reduced by 25% compared to the control. During scientific and economic experiment, it was found that the replacement of cuprum sulphate with its proteinate with the same concentration in the feed has a positive effect on the average daily gain of broiler chickens, and therefore a live weight. Thus, the animals from the 2nd experimental group exceeded control analogues by 7.5% in average daily gain and by 9.4% in body mass at the end of the experiment. Reducing the concentration of Cuprum in the feed of chickens from the 3rd experimental group by 25% (the source of the microelement is cuprum proteinate) compared to the control also had a positive effect on the productivity of these animals. They exceeded control analogues in terms of average daily weight gain by 3.8%, and in terms of live weight by 5.8%. At the same time the direct correlation between animal productivity and quantity of the consumed feed was noted. Thus, broilers from the 2nd experimental group consumed more feed by 3.3% compared to control peers. The chickens from the 3rd experimental group exceeded controls by 1.5% in this index. Thus, cuprum proteinate is a more efficient source of Cuprum for broiler feed. The concentration of this microelement in the feed of these animals aged 5-21 days should be 18.2 g/t, 22–35 days - 16.8 g/t, 36–42 days - 12 g/t or 16.5 g/t on average during the experiment.

This experiment was carried out with the objective of determining the macrominerals (Ca, P, Mg, K and Na) requirements of Nellore steers under grazing. Twenty four Nellore steers (371 ± 14 kg of BW and 26 mo old) were used. Four steers were slaughtered at the beginning of the experiment (reference group), serving as a reference in subsequent study. The remaining 20 animals were weighed and distributed into a completely randomized design with four supplementation levels offer: 0.0 (mineral mixture - control), 0.3, 0.6 and 0.9% of BW, with five replications. The supplements, based on ground corn, soybean meal and/or urea, were previously balanced to achieve an average daily gain of 350, 650 and 850g, respectively, for the different supplementation levels offer. The contents of macrominerals retained in the animal body were determined by regression equations of the macrominerals body content logarithm in function of the empty body weight logarithm (EBW). Net macrominerals requirements for a gain of 1kg of EBW were obtained using the equation Y'= b.10ª.Xb-1, with a and b, respectively, the intercept and the regression coefficient of the prediction equations of macrominerals in the animal body contents for each macromineral considered. The concentrations of all macrominerals, in the empty body weight and gain of the empty body weight, decreased with the increase in the body weight. Total calcium and phosphorus dietary requirements are higher than those recommended in the literature.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

The combined effect of homobiotics, probiotics based on recombinant strains of g. Bacillus, & enrofloxacin on the dynamics of body weight gain in geese was studied. According to the principle of steam-analogs, one control and five experimental groups of 10 goslings in each group were formed. Gosyatam experimental groups used homobiotics vetom 15.1; vetom 13.1 incombination with enrofloxacin followed by replacement with a probiotic preparation Vetom 1.2. The absolute body weight and average daily gain in geese under the influence of the studied drugs increases. The severity of the effect depended on the pharmacological composition of the drugs used. The maximum absolute weight gain was observed when using the drugs according to the scheme: vetom 13.1 at doses of 25–50 mg/kg for 16 days, with further use of a 10% enrofloxacin solution at a dose of 0.5 ml/kg for 5 days and in The experiment period was 1.2 at a dose of 50 mg/kg for 16 days. After the cessation of the use of drugs, the growth rate increased for 30 days when prescribing the drugs according to the scheme: veto 13.1 at a dose of 50 mg/kg for 16 days and with further introduction of homobiotic veto 1.2 into the bird in a dose of 50 mg/kg for 16 days. The maximum average daily gain in live weight of geese was observed in the period from the 16th to the 32nd day with the administration scheme: homobiotic vetom 13.1 at a dose of 25 mg/kg of body weight 1 time per day for 5 consecutive days, then every other day for 16 days, then daily 10 % solution of enrofloxacin at a dose of 0.5 ml/kg of body weight for 5 days, then vetom 1.2 at a dose of 25 mg/kg once a day for 16 days in a row. And the maximum average daily gain in the post using period of the drug was observed on the 32nd day of the study according to the scheme: homobiotic veto 15.1 at a dose of 50 mg/kg of body weight 1 time per day for 16 days, then daily with vetom 1.2 at the same dose 1 once a day for 16 days. The studied drugs in the applied doses did not have a toxic effect on the physiological state of geese.

We investigated changes in the caecal microbial composition and metabolic compounds of broiler chickens weighing approximately 0.8–1.5 kg. Arbor Acres (AA) broilers (n =186) were divided into four groups (A–D) according to body weight on day 35. The results showed that there were significant differences in the average daily feed intake (ADFI), average daily gain (ADG), and feed-to-gain ratio (F:G) of chickens (P less than 0.05). The abundance of 11 genera were found to be significantly different in the four groups (P less than 0.05). The broilers with poor performance had increased levels of D-mannose, hexadecanoic acid, cholesterol, L-valine, L-leucine, glutamic acid, glucopyranose, á-D-allopyranose, and phosphoric acid (P less than 0.05) in the cecum. Microbial compositions were different in the ceca of broilers with different growth performances, and higher growth performance correlated with changes in metabolic pathways related to energy, amino acids, and others.

The studies were carried out on three groups of superreplacement heifers of the Simmental breed, which were impregnated at the body weight of 360 kg. In the first group there were 32 unimpregnated heifers, in the second – 28 heifers, in the third – 30 heifers. The heifers of the first group after growing at the age of 18 months were taken for meat. 56 heifers gave the crop. The heifers were transferred for reproduction, and the bull-calves were put on cultivation and further fattening. To obtain well-fed animals, special diets were made so that the average daily gain was at least 650-700 g. After calving, the cows of the second group were taken for meat, and the cows of the third group were put on a 3-month fattening, and then taken for meat. The pre-slaughter weight of animals of the first group was 52 kg lower than that of animals of the second group and 104.7 kg lower than that of the third group. The difference was statistically significant at P>0.999. The interior fat mass was higher in the carcasses of cows of the second group by 1.1 and 3.2 kg compared to the animals of the third and first groups. The carcass yield was almost at the same level slightly ahead of the animals of the first group. Their slaughter yield was 60.1%, in other groups – 58.8-59.6%. The meatiness ratio was slightly higher in animals of the first group. The carcass weight of the first-calf heifers of the third group was 27.4 kg higher than that of the second group. Compared to the first group, this figure is higher by 52.6 kg. Specific carcass meat weight of the animals of the third group was 82.75%, which is higher than in the second and first groups by 0.41-0.85%, respectively. Heavy cowbanes weighing 32.6 and 40.4 kg were obtained from the animals. The skin of animals of the third group was 3.5-21.6 dm2 larger in area than of the animals of the second and first groups. Feeder bull-calves (n=27) had a removable mass of 532 kg. Heavy (282.3 kg) carcasses of good morphological composition were obtained from them. The sales revenue from first-calf heifers (second group) was higher than fattened heifers by 10.4%, and in comparison with fattened animals after calving (third group) it was lower by 9.4%. From the sale of one cow with a crop, 2.9 times more profit was received than from the sale of a heifer.
