Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

The work aims to study the effect of different doses of the experimental probiotic preparation “Plantarum” when fed to pregnant animals on their reproductive qualities, as well as on the growth and development of young animals. To obtain young animals, four groups of goats were formed in the type of the Saanen breed, 20 heads each. In the first (control) group, the animals received a standard diet, in the diet of the animals of the second, third and fourth groups in the second half of pregnancy, the probiotic preparation “Plantarum” was additionally introduced, containing Lactobacillus Plantarum, Propiobacterium freudenreihii, in dosages from 0.4 to 0.8 ml/kg of body weight per day. From the offspring of the goats of the experimental groups, four groups of 12 goats were formed. The highest percentage of preservation (94%) and the highest business output of kids per 100 queens (150%) were observed in the fourth experimental group (0.8 ml). The goats of the second, third and fourth groups exceeded the body weight of their contemporaries from the control group by 3%, 6.3%, and 8.8%. The highest indices of the absolute increase in body weight by age periods were noted in the fourth group of goats. There were no significant differences in body build indices during the experiment between the goats of the control and experimental groups. Thus, the maximum positive effect was observed with the introduction of a probiotic preparation into the diet of pregnant goats at a dose of 0.8 ml/kg of body weight per day.

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.

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 effect of pyridoxine hydrochloride on the body mass of animals, absolute and average daily increment, relative growth rate, growth factor of live weight and multiplicity of increase in live weight of calves in the early stages of postnatal ontogenesis were studied. For the experiment, six groups of one-day calves (control and five experimental) were formed, with 5 animals in each, which, in addition to the main diet (MD), fed pyridoxine hydrochloride in different doses, according to the scheme: control group – MD, I experimental group – MD + 1 mg/kg g. m pyridoxine hydrochloride, II – MD + 2 mg/kg g. m of the preparation, ІІІ – MD + 3 mg/kg of w. m., IV – MD + 4 mg/kg g. m and V experimental group – MD + 5 mg/kg g. m pyridoxine hydrochloride. Conditionally, the research was divided into four periods: colostrum – from birth and up to 5 days, until the formation of digestion – from 5 to 21 days, the period of the formation of digestion scar – from 21 to 60 days and the end of the milk period – from 60 to 90 days. It was established that feeding to calves with pyridoxine hydrochloride resulted in an increase in the live weight of 60 days of calves by 5.9% in the second group (P < 0.05), by 8.7% in the third group, by 8.3% in IV and 9.2% in V groups (P < 0.001) and for 90 days it was higher by 9.3%, 9.1%, 9.2% and 9.1% respectively (P < 0.05). The highest average daily increments were in the colostrum period in calves IV and V groups, which were added to the main diet, respectively, 4 and 5 mg/kg b.w. pyridoxine hydrochloride, in the period prior to the formation of digestion scar in calves of group IV, in the period of the formation of digestion scar in calves of the III group and at the end of the milking period in calves of group V. Absolute incresements of calves in the colostrum period and the period prior to the formation of digestion scar were the highest in calves of Group IV and the difference in control was respectively 0.34 and 1.05 kg. During the period of the digestion scar formation and the end of the milk period, the highest absolute increases were in calves of group V, which was added to the main ration of 5 mg/kg b.w. pyridoxine hydrochloride. The highest increase in body weight of calves in colostric period and prior to the operation scar rate was in group IV, the period of digestion scar formation was in the third group and during the completion period of milk in the second group of calves. In colostric period the increase of live weight was higher in calves III, IV and V groups of 5 to 21 days in calves of group IV, from 21 to 60 days in the third group and during the completion period of milk in the second group of calves.

The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.

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

One of the ways to increase meat resources is to improve the condition of livestock on farms in the Russian Federation. This is due to the fact that when the fatness of the animal increases, the meat yield in the carcass increases. The purpose of the researches was to establish the features of the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed. In order to achieve this purpose two groups of steers-analogs of Hereford breed (control and experimental) at the age of 6 months per 10 head in each have been formed. The time of the experiment was: the preparatory period of 22 days and the main one 275 days. Steers of the control group have received the main farm ration, and steers of the experimental group have received the main ration and feed protein additive Biovitel for 30 days with 10-days interval at the dose of 100 g per head during the sixth month. The results of researches on the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed have been refl ected in the article. The addition of the feed additive Biovitel to the main ration of the experimental group of steers helped them to achieve a higher live weight and higher average daily gains under the same environments of feeding and housing in all age periods. By the end of the experiment (15 months) the experimental group of steers have reached the live weight of 430,2 kg, which was higher by 19,9 kg or 4,9 % compared to the control group of steers. In order to improve the quality of beef and increase its production more intensive rearing of steers of Hereford breed with the use of feed protein additive Biovitel has been justifi ed. The recommended dose is 100 g per head. This dosage allows you to achieve the average daily gain of 967,5 g and the average live weight of 430,2 kg by 15 months of age, reduce the prime cost and increase the profi tability of beef production.

During the study, it was found that an increase in the dose of sweet yellow clover extract from 0.5 to 2.5 mg/kg of live weight per day contributed to an increase in the number of: hemoglobin by 1.83 g/l (1.79%), leukocytes by 0.14 thousand 109/l (2.34%), total protein in blood serum of sheep by 0.43 g/l (0.7%), glucose in blood of sheep by 0.18 mmol/l (4.19%), calcium in blood of sheep by 0.14 mmol/l (5.32%), phosphorus in blood of sheep by only 0.08 mg/100 ml (1.6%), contributed to an increase in the live weight of sheep by 220 g (2.18%). In the control group, two sheep out of six got bronchitis. The percentage of sheep with bronchitis was 33.33%. After feed to the sheep different doses of sweet yellow clover extract, the sheep in groups I and II of the experimental groups had one sheep each (16.67%), while in groups III, IV and V there were no sheep with bronchitis. Thus, increasing the sweet yellow clover dosage in sheep’ diet reinforced their immunity. In the control group and in the first experimental group, one sheep out of six came down with dyspepsia. The percentage of sheep with dyspepsia was 16.67%. After feed to the sheep doses of sweet yellow clover extract, there were no dyspeptic diseases in sheep.

The article is devoted to the study of the intensity of growth and development of quails us-ing a nanostructured preparation. The object of the study was the Texas white quail (n = 45), at the age of 10 days, which were divided into 1 control and 4 experimental groups. Birds from the exper-imental groups were given a complex preparation in various doses and forms to the main diet, con-sisting of compound feed DK-52. It was found that birds are intensively gaining live weight in the first 28 days of feeding. The average daily gains in live weight increased in quails from group 1 by 8.3 %, group 2 – 12.9 %, group 3 – 3.8 % and group 4 – 24.9 % compared with birds of the control group. Starting from the 35th day, there is a decrease in the average daily gain. The best results for both 28 and 56 days were shown by quails in group 4, which received a complex preparation at a dose of 1 % of the diet weight.
