Breeding, preserving, and successfully rearing young animals resistant to various environmental influences is one of the main parameters of effective livestock management. The study aimed to study the indicators of natural resistance and the growth rate of calves under the influence of dietary supplements. The studies were carried out on four groups of black-and-white calves, 10 heads each, at the age of 2-5 months. The dairy calves of the control group were fed according to the ration adopted on the farm (basic ration, including cereal-legume hay, whole milk, milk replacer, concentrates, chalk, salt). In addition to the main diet, the animals of the experimental groups were given a dietary supplement. At 2-3, 3-4, and 4-5, months of age, calves were given 12-23, 19-38, and 23-47  g.head-1 of dietary supplement per day, respectively. The article deals with the effect of a forest biomass supplement on the morphophysiological parameters of calves. Biochemical blood analysis and the features of metabolic processes in the bodies of animals are studied. The results indicated that the use of a dietary supplement at a dosage of 30 g/head of cattle per day contributes to the highest increase (9.9%) in live weight gain of experimental animals and an improvement in natural resistance parameters (bactericidal activity of blood serum, phagocytic activity of neutrophils). Based on the data of biochemical and haematological blood tests, the authors conclude that the inclusion of a dietary supplement in the diet of calves has a positive effect on the indices of natural resistance and the course of nitrogen metabolism.

This research aims to realize the adaptive and productive capacity of calves with immunotropic agents PS-6 and Prevention-N-E. The object of the research was black-and-white calves, which were transferred to individual pens a day after birth and kept there until 30 days of age, then in open-air pavilions until they reached 180 days of age, that is, they were reared using adaptive technology. According to the principle of analogs, 45 calves of 1 day age were selected, were divided into 3 groups: control, 1st experimental, and 2nd experimental. To increase resistance to the pressure of environmental factors and realize the bioresource potential of the adaptive and productive traits of the organism, the calves of the 1st and 2nd experimental groups were injected intramuscularly immunotropic preparations PS-6 and Prevention-N-E respectively, at a dose of 3 ml per animal on the 2nd-3rd and 7-9th days of life. The animals of the control group were not exposed to immunoprophylaxis. The morphological blood profile of calves was studied against the background of the application of biological products. Thus, intramuscular injection of immunotropic agents PS-6 and Prevention-N-E into calves had a positive effect on the morphological blood composition. The number of erythrocytes in the blood of calves of the 1st and 2nd experimental groups at the age of 30 days was significantly higher than the control values by 5.4 and 6.4%, respectively (P<0.01). The concentration of hemoglobin was significantly higher in the blood of the calves of the 1st and 2nd experimental groups, starting from 30 days of age, by 6.3-11.7% and 6.7-14.4%, respectively. White blood counts in the blood of animals of different groups did not have a statistically significant difference. Consequently, the use of immunotropic drugs PS-6 and Prevention-N-E in calves activates the erythrocyte lineage of hematopoiesis, without significantly affecting leukopoiesis. The results of periodic weighing of calves showed that at the age of 60, 90, 120, 150, 180, 360, and 540 days, the live weight of young animals with the injection of the immunotropic agents PS-6 was significantly higher than the control values by 2.6, 3.4, 5.0, 6.2, 7.0, 9.4 and 12.2 kg (P<0.05-0.01), and with the application of Prevention-N- E - by 3.6, 4.8, 6.6, 8.0, 9.0, 12.2 and 16.4 kg, respectively (P<0.05-0.001).

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 reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

ABSTRACTResults are reported from four trials in which neonatal calves were given either whole milk or milk substitute containing the lactoperoxidase system.Trial 1 was a pilot trial conducted in Sweden in which calves given whole milk with the lactoperoxidase system gained significantly more weight than controls (P< 0·05). Trials 2, 3 and 4 were carried out in successive years at the National Institute for Research in Dairying, using large numbers of newborn, female Friesian calves. In trial 2 a significant positive effect of the lactoperoxidase system with whole milk on live-weight gain was established by 3 weeks of age (P< 0·05) and sustained until weaning at 5 weeks. There was no significant effect of the lactoperoxidase system for the milk substitute treatment. In trial 3 the whole milk comparison from trial 2 was repeated. There was a significant positive effect of the lactoperoxidase system on the live-weight change after 2 weeks of age only (P< 0·05). In trial 4 two different methods of activating the lactoperoxidase system were compared for calves given whole milk. There was no effect of either method on the live-weight gain of the calves. However, as the levels of scouring were extremely low for all calves, a comparison of the two methods of activating the lactoperoxidase system was not justified. The combined results from trials 2, 3 and 4 confirmed that the lactoperoxidase system significantly increased the live-weight gain of calves given whole milk, despite the fact that the overall level of mortality and incidence of scouring was low in these trials.

Clinical tests were carried out in the representative group of patients with focal left-sided pneumonia (5 men and 7 women aged 18–41). Special-use product was included in in-patient department patients’ diet: 2 tablets in the first intake, then 1 tablet 4 times a day. Course of treatment was 21 days. Biologically active dietary supplement was prescribed together with general therapeutic treatment according to generally accepted standards of care. Control group included 15 patients randomized depending on sex and age who took only medicine. The author measured body temperature, studied the results of general blood tests, determined the level of C-reactive protein and seromucoids, performed R-graphy of lungs, electrocardiogram before and after treatment, analyzed clinical symptoms (cough, type of expectoration, shortness of breath). Composition of the special-use product was scientifically justified taking pharmacological characteristics of its ingredients and their active agents into account. Introduction of the biologically active dietary supplement in addition to the prescribed therapeutic treatment gave positive effect in relation to the inflammatory process: the patients could easier clear their throats from expectoration, coughed less frequently, and had less intense shortness of breath. It was evident that symptoms of disease recrudescence decreased. It appeared in the decreased intensity and length of fever. In case of acute respiratory viral infection the biologically active dietary supplement had antipyretic activity due to the anti-exudative effect of its ingredients. The author determined the anti-inflammatory effect and reduction of acute intoxication symptoms taking the results of general blood analysis into account. Patients who took special-use product had lower values of an inflammatory process marker – seromucoids. Tissues restored easily. The tested product has anti-inflammatory, antipyretic and analgesic properties. It can be used in complex treatment of acute inflammatory diseases and recrudescence of chronic inflammatory processes.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

To improve the adaptation of the pancreatic microflora to changes in the diets of calves and for the rational use of feed, in intensive cultivation, it is desirable to change the composition of feed probiotic supplements according to the age of the animals. Each age group of calves responds differently to live weight gain on probiotic feed additives. Feed supplement Immunobacterin-D containing Bacillus subtilis, Bacillus licheniformis has a positive effect on natural resistance, increases the average daily gain and has a preventive effect on diseases of the digestive tract of calves. But for 2 months of continuous feeding can cause suppression of natural resistance of some animals. When baker's yeast is added to the feed additive (B. subtilis, B. licheniformis 1 × 1010 CFU / g, Sascharomyces cerevisiae 1 × 109 CFU / g), the dry form of the product makes it possible to feed it with compound feed. The use of immunobacterin-D with yeast in 3-month-old calves in experimental animals in the clinical examination for fatness and coat condition looked better. Calves of the experimental group during this period added in increments of 276 g in the previous month, the arithmetic mean of the average daily gain of live weight was 820 ± 180 g, and in the current 1096 ± 90 g, which indicates a positive effect of yeast (especially live) on the productivity of calves at this age. For studies on heifers in a farm with lower average daily gains in live weight, we received a smaller percentage increase in gains with the use of feed probiotic supplement Immunobacterin-D with baker's yeast. When adding to the feed additives at a dose of 40 g and 20 g to heifers 350–400 kg live weight of the animal had an average daily gain of live weight in the first group of 500 ± 17 g, in the second 440 ± 30 g, and in the control 414 ± 12 g, which is 20.8 and 6.3 % more than in the control group. The use of yeast in feed additives confirms the pattern of increasing the percentage of additional average daily gain. That is, with higher average daily gains, we get a higher percentage of additional growth from feeding a probiotic feed additive containing baker's yeast.

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.

The reaction of the organism of broiler ducklings to the introduction of the probiotic additive "Lactobifadol" into the organism when reared up to 7 weeks of age was investigated. A positive effect was achieved to increase the live weight of the experimental poultry by 5.0 % (p <0.5), the average feed consumption per 1 kg of live weight gain in the group of broiler ducklings fed with Lactobifadol feed was 4.7 % less when compared to intact poultry. The dynamics of feed consumption per 1 kg of live weight gain in the first three weeks of rearing was descending, and from 4 weeks of age until the end of rearing, fodder consumption increased significantly. For 6 weeks of growing, the average consumption of compound feed per head per day in the control group of broiler ducklings was 157.5 g, in the experimental group – 158.5 g per 1 bird/day. The inclusion of "Lactobifadol" in the diet to a certain extent stimulates the processes of erythrocytopoiesis, providing, within the physiological norm, an increase in the level of hemoglobin and the number of leukocytes.

В статье приводятся показатели, характеризующие рост и уровень мясной продуктивности бычков черно-пестрой породы при скармливании им люцернового сенажа, заготовленного с разной дозировкой биозакваски на основе пропионовокислых бактерий. Препарат вводили в процессе закладки сенажа в виде рабочего раствора в количестве 2, 4 и 6 л на 1 т консервируемой массы. Опыт проводился в условиях Республики Башкортостан. Для этого 40 10-месячных бычков разделили на 4 группы. Молодняк контрольной группы получал неконсервированный сенаж, а опытных групп — сенаж, с закваской на основе пропионовокислых бактерий в указанных выше дозах. Установлено, что молодняк опытных групп лучше рос и развивался. В 12 мес его живая масса была выше, чем в контрольной группе на 2,50—6,10 кг (0,73—1,77%); в 15 мес — на 9,34—15,14 кг (2,20—3,57%; Р<0,05); в 18 мес — на 15,51—23,31 кг (2,10—4,66%; Р<0,05—0,01). Более высокая энергия роста молодняка опытных групп при откорме на рационах, включающих консервированный сенаж, способствовала и более высоким убойным показателям. Наилучший эффект проявился у бычков, потребляющих сенаж с закваской на основе пропионовокислых бактерий в дозе 4 л рабочего раствора на 1 т зеленой массы. Данная дозировка обеспечивает увеличение массы парной туши на 12,9 кг (4,79%),The article presents the indicators characterizing the growth and level of meat productivity of bull-calves of the black-and-white breed, when they are fed alfalfa haylage, harvested with different dosages of biosakvaski based on propionic acid bacteria. The drug was administered in the process of laying haylage in the form of a working solution in the amount of 2, 4 and 6 liters per 1 ton of preserved mass. The experiment was conducted in the conditions of the Republic of Bashkortostan (Alga, collective farm, Chekmagushevsky district). For this 10-month gobies were divided into 4 groups. The young of the control group did not receive canned haylage, but the test groups received haylage, with sour based on propionic acid bacteria in the above doses. It was found that the young of the experimental groups grew and developed better. So at 12 months of age, their live weight was higher than in the control by 2.50—6.10 kg (0.73—1,77%); in 15 months — by 9,34—15,14 kg (2,20—3,57%; P<0,05); in 18 months — by 15,51—23,31 kg (2,10—4,66%; P<0,05—0,01). The higher growth energy of the young of the experimental groups during fattening on rations, including canned haylage, contributed to a higher slaughter rate. The best effect was manifested in calves consuming haylage with ferment based on propionic acid bacteria in a dose of 4 liters of working solution per 1 ton of green mass.This dosage provides an increase in the mass of steam carcass by 12,9 kg (4,79%), carcass output by 1,0%; slaughter weight — by 14,0 kg (4,95%; P<0,05); slaughter yield — by 1,2%.
