It is known that one of the most important reasons for the birth of weak calves is the impact of adverse factors on the physiological status of the cow, which in turn affects the intrauterine and postnatal development of the fetus and newborn. The results of studying the introduction of different doses of tissue biostimulator to cows during the dry period and its effect on the development of the conformation of calves received from them have been presented in the article. The experiment was carried out in 2019 on cows of Priobsky type of Black-and-White breed and calves obtained from them. In order to conduct the experiment four groups of dry cows-analogs have been formed with 10 heads in each for 55–60 days before the expected calving at the age of III lactation and older. When selecting animals the live weight and milk productivity of cows for the previous lactation have been taken into account. The highest growth rate has been observed in calves from cows the 2nd experimental group, which exceeded the control by 24,4 % (P ≤ 0,001). The best indicators of conformation development have been also observed in calves obtained from cows of the 2nd experimental group, which were injected subcutaneously with 22,5 ml of tissue preparation. So, oblique body length have been greater by 12,6 % (P ≤ 0,001), chest girth by 17,3 % (P ≤ 0,001), width of hook bones by 21,0 % (P ≤ 0,01), the width of the pin bones by 15,0 % (P ≤ 0,05). The lengthiness index was by 11,5 % higher (P ≤ 0,001), the blockiness index was by 4,1 % higher (P ≤ 0,05), and the boniness index was by 10,6 % lower (P ≤ 0,05) than in the control group herdmates.

The paper demonstrates the results on the effect of new specimen Vetom 20.76 on concentration of leukocytes in the blood of geese on the basis of the predatory fungus Artusbotus oligospora. In order to achieve the goal of the experiment, one control group and six experimental groups were arranged on the principle of paired analogues. Each group contained 10 geese aged 1 month. The geese from the experimental groups received Vetom 20.76 in different doses in the morning with water once a day: the geese of the 1st experimental group - dose of 0.5 ppm/kg of live weight during 15 days; 2nd experimental group - 1 ppm/kg of live weight during 15 days; 3rd experimental group - 2 ppm/kg of live weight during 15 days, 4th experimental group - 0.5 ppm/kg live weight during 30 days, 5th experimental group - 1 ppm/kg live weight during 30 days and 6th - 2 ppm/kg live weight during 30 days. The geese of control group didn’t receive the specimen. The concentration of leukocytes in the blood of experimental geese increases in the period of specimen application as well as in the period of its aftereffect. If Vetom 20.76 is prescribed for 15 days, the effect of leukopoiesis stimulation finishes on the 30th day. If the specimen is applied during 30 days, the leukocytes in the blood continue to increase up to the 60th day. This long-term application of Vetom 20.76 dosed 0.5ppm/kg increases leucocytes within the physiological norm. Application of higher doses (1 and 2 ppm/kg) the leukocyte concentration conforms to the physiological norm

The research aimed at the development and introduction of extracts of medicinal plants for the transition to a highly productive and antibiotic-free agricultural economy has been carried out in the Kemerovo region,. The purpose of the research was to study the effectiveness of the use of extracts of medicinal plants (maral root, stinging nettle, creeping thyme and calendula) to increase the growth rate of calves of Black-and-White breed. A comparative analysis of the effect of medicinal plant extracts on the growth rate of calves of Black-and-White breed has been carried out, the rationale for choosing the most effective combination of them has been given. A pilot batch of a mixture of two extracts of medicinal plants of maral root (Leuzea carthamoides) at a dose of 0,125 mg/kg and stinging nettle (Urticadioica L.) at the dose of 7,0 mg/kg for introduction into the diet of calves has been made. During the experiment all calves have been receiving the mixture of extracts of maral root and stinging nettle were characterized by a high growth rate and as a result by the end of the experiment, the live weight of calves in the experimental group exceeded 2,27 kg or 4,5 % of the indicator in the control group. In this regard, it has been proposed to include in the feeding diet of calves the mixture of extracts of medicinal plants such as maral root at the dose of 0,125 mg/kg and stinging nettle at the dose of 7,0 mg/kg, to increase the growth rate of calves from 14 to 28 days of age.

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.

In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

The antioxidant drug "E-selenium" was used to reduce the processes of LPO in the body of fresh cows. Two groups were formed from the analogous cows of the black-and-white breed: The Control was intact, Experienced received the antioxidant drug injection at a dose of 10 ml at the rate of 1 ml per 50 kg of live weight per head for 4 months of lactation from the second. The diets of animals of all groups were the same, balanced in nutrients and met the standards of the RAAS. The duration of the experiment was 150 days. During the period from the 3rd to the 5th month of lactation, there was a positive dynamic in increasing the number of fat globules in the milk of cows of the Experimental group. By the end of the 4th month, it was higher than the Control by 8.9 %. This confirms the active effect of the drug "E-selenium", which contributes to a positive dynamic in increasing the size of fat globules. Non-enzymatic antioxidant tocopherol is an active element of the anti-oxidative system. Selenium stimu-lates the body's own antioxidant system. In both experimental groups, the relationship between the concentration of peroxidation products and the quantitative composition of fat globules and their size was established. In the milk of cows of the Experimental group, the oxidation processes were inhibited by neutralizing the products (POL), increasing the number of large fat globules and the total fat content in the milk.

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.

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.

The purpose of the researches was to study the influence of different doses of smectic kizelgur and calf skim milk replacer in the recipes of compound feed for young pigs under the conditions of industrial pork production technology. The experimental part of the work has been performed under the conditions of the pig complex of LLC “BMPK” in the Karachevsky area in the Bryansk region. The research materials were compound feed for young pigs on fattening in the inclusion of different doses of smectic kizelgur. The infl uence of feeding compound feed with different doses of smectic kizelgur and calf skim milk replacer to young pigs on productivity, digestibility of nutrients and use of nitrogen, morphological and biochemical parameters of blood, fattening and meat traits of young pigs has been studied. Effective recipes for feeding compound feeds to young pigs prepared with the inclusion of different doses of smectic kizelgur and calf skim milk replacer have been identified. The data have been obtained from the first experiment of young pigs when them fed compound feed with different doses of smectic kizelgur; it has been followed that at the end of fattening the biggest live weight of gilts had in the 4th experimental group fed compound feed, which included 3 % smectic kizelgur. The influence of the additive on changes in live weight and daily gains when adding smectic kizelgur to compound feed in doses of 1,5 and 2,0 % was less, but the trend to increase these indicators over the period of fattening has remained. In the second experiment young pigs have been fed by compound feed, which included different doses of smectic kizelgur and calf skim milk replacer the average daily gain in live weight was higher in the 3rd experimental group, where they fed compound feed with the addition of 2,5 % smectic kizelgur and 2,5 % calf skim milk replacer by 2,2 %, than in the control group. The highest efficiency has been also obtained in the 3rd experimental group, where the monetary revenue has been received by 2160 rubles more in comparison with the control group of pigs.

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%.

Summary. Practical interest at the present stage in feeding highly productive cows is the use of fl axseed and rapeseed press cakes, which are sources of energy, high-grade protein and polyunsaturated fatty acids. Rapeseed and linseed press cakes are excellent protein feed for cattle. In concentrates for this animal species they may be the only high-protein components. The purpose of the work was to carry out comprehensive research on fi rst-calf heifers productivity traits, milk quality and its technological properties when using linseed and rapeseed press cakes in their rations. The research has been carried out in JSC “Uchkhoz Iyulskoe of Izhevsk State Agricultural Academy”. The object of research was fi rst-calf heifers of Black-and-White breed. In order to conduct research, four groups of fi rst-calf heifers have been formed – a control group and three experimental groups of 12 animals in each group. A comprehensive evaluation of productive traits, milk quality, its technological properties, as well as the quality of dairy products (cheese, cottage cheese, yogurt) when used in fi rst-calf heifers feeding various cakes (linseed and rapeseed). The lowest prime-cost of 1 kg of milk has been obtained with the simultaneous use of linseed and rapeseed cakes of 14,0 rubles, which was less than in the control group by 2,1 rubles, the 1st experimental group by 1,7 rubles and the 2nd experimental group by 0,7 rubles. The largest gross profi t from milk sales has been received in the 3rd and 2nd experimental groups of 55 744 and 48 202 rubles, respectively. The level of profi tability in all groups was high and ranged from 36,6 % in the control group and up to 57,1 % in the 3rd experimental group. The result of the conducted researches has proved the effi ciency when feeding lactating fi rst-calf heifers of Black-and-White breed of rapeseed press cake and a mixture of rapeseed and linseed press cake in 1 : 1 ratio when replacing 30 % (on crude protein content) of sunfl ower press cake in their rations.
