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.

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.

Relevance. Modern turkey crosses have a genetically determined high growth rate. These farm birds are very sensitive to even minor fluctuations in their diet, are susceptible to a deficiency of amino acids, protein, mineral elements and vitamins, which can contribute to a decrease in their productivity, the development of pathological processes and diseases. The use of modern technologies and scientific achievements has made it possible to prepare a new product — modified zeolite. This natural mineral is already free of impurities and microbes, with open pore windows, has a high ability to selectively exchange, and is obtained by various methods of activating zeolite in industrial conditions. At the same time, Ulyanovsk specialists have mastered the technology of enriching modified zeolite with useful substances.Methods. The aim of the work was to study the effect on the body of turkeys and the level of their productivity of additives based on modified zeolite enriched with amino acids. The experiment was organized for 60 days on 250 turkeys of the breed Hybrid Cread-mayker aged 55–60 days in the conditions of the Ulyanovsk region. The control group received the main ration (MR), the experimental group was given once a day in addition to the MR in the morning feeding in a mixture with mixed feed 5% additives of modified zeolite enriched with amino acids.Results. The inclusion of a supplement based on modified zeolite enriched with amino acids in the diet of turkeys does not have a negative effect on the hematological parameters of their blood, all indicators corresponded to the physiological norm. During the experiment in the 2nd group, the live weight of poultry was obtained larger by 8.70%, which amounted to 12,296 kg, respectively, more profit was obtained from the sale of turkey meat, total revenue was 133,210, and additional profit was 27,960 rubles, 2.41 rubles of profit was received for 1 ruble of costs. Тhe data indicate the normalization of mineral homeostasis in the body of turkeys and better absorption of nutrients in the feed diet.

Least cost rations for specific rates of growth in the growing and finishing periods were given to pigs slaughtered at 200 lb. live-weight. During the growing period pigs grew very close to the planned rates in spite of the fact that some food was rejected. Pigs given rations for a low growth rate in the growing period grew slightly faster than planned in the finishing period. In the finishing period pigs given rations for the high growth rate grew on average very near to this rate. The pigs given the ration for the low growth rate grew slightly faster than planned. Food conversion efficiency was for all pigs very near to, or slightly better than, that planned. The rations had no adverse effect on carcass quality.

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%.

The aim of the research was to establish quantitative and qualitative indicators of meat productivity of Simmental bull calves of various constitutional types when raised using the technology of beef cattle breeding. The maximum growth rate and the highest yield of meat products were obtained from Simmental bulls of the meat and dairy type when they were raised and fed according to the technology of beef cattle breeding. Receiving from the mothers for 205 days of the sucking period more fatty milk, they gave 1250 g of gain per day and reached 289.7 kg of live weight by the cut. Having retained a high growth rate in the future, they at the final fattening gave 1321 g of gain per day and at 20 months the live weight was 659.3 kg. The superiority of Simmentals over analogues was natural by 3.4–13.3% by weight of the steamed carcass, by 0.4–1.8% in slaughter yield, by 1.4–11.1 kg in terms of the amount of pulp in the carcass and pulp per bones by 0.1–0.3 kg, protein in meat by 0.12; 1.19; 2.59 kg and the amount of energy in the pulp by 0.14; 0.44; 1.75 MJ. Simmental bulls of the meat and dairy type also have a high ability to transform protein and feed energy into protein and energy from the pulp of the carcass.

Pork production today is based on intensive management of the industry and quality improvement of breeds. In our country, there are changes in the breed structure in the direction of the predominant focus on breeds of meat productivity. In this regard, an important place is given to pigs of the Duroc breed, which have been used in Ukraine for a long time. Numerous studies have shown that under the same conditions of feeding, keeping fattening and meat qualities of pigs of different breeds and interbreed combinations at different weight conditions are not the same. The purpose of the work is to study the fattening and meat qualities of the intra-breed type of Duroc pigs of the Ukrainian selection «Stepovy» (DUSS) with different methods of breeding during fattening to high weight conditions. The study of fattening and meat qualities of pigs of interbreed type «Stepovy», Large White foreign (LW (FS)) and Landrace of French (L (FS)) selection took place in the conditions of SVC «Agrofirm «Mig-Service-Agro» of the Mykolaiv region. A comparative assessment of fattening and meat qualities of young animals of the following combinations: I – DUSS×♂DUSS – control group, II – ♀LW(ZS)×♂DUSS, III – ♀DUSS×♂LW(ZS), IV – ♀L(FS)×♂DUSS, V – ♀DUSS×♂L(FS) – experimental groups, when animals reach a live weight of 100, 120 and 140 kg. The highest fattening rates for three variants of fattening had young animals obtained from a combination of sows of the interbreed type «Stepovy» with boars of the Landrace breed. The expediency of fattening these pigs to high weight conditions was noted, as they maintained a high growth rate during fattening to a live weight of 140 kg. The greatest value of the complex index of fattening and meat qualities had animals of the V experimental group in the range of 211.9-203.6. When the animals reached a live weight of 100-140 kg, the lowest value of this indicator was characterized by animals of the II experimental group. It was found that the relative rate of meat yield at the slaughter of 100-140 kg was different and depended on the genotype of the animals and was in terms of groups – 64.12–53.81 %. After the meat came out of the carcass, purebred animals of the interbreed type of the Duroc breed of the Ukrainian selection «Stepovy» (I control group), local young growth of a combination ♀DUSS×♂L(FS) were better, at them at slaughter in 100–140 kg relative exit m was: 63.90–56.14 % and 64.12–57.53 %, respectively.

Increasing the protein nutritional value of rations through the use of legume-grass crops, press-cakes and oil-cakes, complete provision of high-quality animal feed, balanced in protein and other components, is the leading direction of solving the protein problem in animal husbandry and remains an urgent topic for research. The purpose of the research was to study the use of hay and haylage from the mixture of Eastern galega and awnless brome in the rations of first-calf heifers instead of the same feed from the mixture of alfalfa and awnless brome. For carrying out scientific and economic experiments in LLC Kushul in the Dyurtyulinsky district in the Republic of Bashkortostan on the principle of pairs-analogs (breed, live weight, age, level of productivity) four groups of first-calf heifers of Black-and-White breed per 10 heads in each have been selected. The inclusion of 4 kg of hay and 10 kg of haylage in the rations of first-calf heifers of the mixture of Eastern galega and awnless brome has a positive effect on increasing the protein content in milk by 3,1 and 3,4 %, sugar by 0,6 and 0,9 abs.%. There was a steady increase in the milk of cows of the experimental groups: carotene, total calcium and inorganic phosphorus compared to the control group where the animals received 4 kg of hay and 10 kg of haylage of the mixture of alfalfa and awnless brome. Thus, studies have shown that the use in rations of first-calf heifers hay and haylage of mixtures of Eastern galega and awnless brome promotes not only productivity, but also improve milk quality.

Due to the intensifi cation of the cattle breeding industry, there is a need to fi nd ways and available methods to increase production and improve the quality of beef based on the use of existing breeding stock of dairy cattle. The success of industrial crossbreeding depends primarily on the correct selection of breeds and their compatibility. The purpose of the research was to study the growth and development of purebred young cattle of Black-and-White breed and crossbreeds with Hereford breed in the Leningrad region. Research and production experiment has been carried out in the training and research farm “Pushkinskoe” of the St. Petersburg State Agrarian University. In the control group purebred animals of Black-and-White breed (9 heads steers and 7 heads heifers), in the experimental group half-blood animals (9 heads steers and 7 heads heifers) have been selected obtained as a result of crossbreeding Black-and-White cows and Hereford sires. The researches have been conducted from birth to 18 months of age. Researches have shown that the crossbreed young animals in comparison with purebreds were distinguished by expressed meat type of physique, a squat body with a welldeveloped back, a fairly wide and deep chest and a strong bone structure. Crossbred animals have been characterized by increased growth intensity. Steers and heifers outperformed their Black-and-White herdmates in terms of daily live weight gain overall over the study period by 170,6 g or 18,8 % , and 130,2 g or 15,6 %, respectively (P ≤ 0,01–0,001). According to the research results, it is recommended that to increase the volume of beef production and more fully realize the productive potential of cattle in the Leningrad region, it is necessary to conduct industrial crossbreeding of holstinized Black-and-White cattle with Hereford cattle. The resulting crossbreed young animals should be raised and fattened up to 16 months of age when steers reach a live weight of 540 kg and feed expenditures per 1 kg of live weight gain of 6,4 EFU, and heifers more than 480 kg and 6,9 EFU, respectively.

AbstractThe commercial crossbreds with various genotypes and different growth rates in terms of the fattening and slaughter value as well as the microstructure and the quality characteristics of musculus biceps brachii were investigated. The experiment involved 38 bulls: 20 crossbreds obtained from Polish Black-and-White Lowland dams (BW) sired by Limousin bulls (LIM) – group I, and 18 crossbreds obtained from BW cows and Simmental bulls (SIM) – group II. The animals of both groups were divided into low growth rate (LG I and LG II; daily weight gain ≤900 g/day) and high growth rate category (HG I and HG II; >900 g/day). The results show that significantly better dressing percentage and carcass conformation (based on the EUROP carcass classification system) were attained by BW × LIM hybrids. The genotype of bulls did not influence the content of valuable cuts in carcass and meat content of cuts, as well as most characteristics of the meat quality. The differences (P<0.05) in anaerobic index were noticed in both genetic groups of bulls in the two growth rate categories. The findings presented in the experiment also show that the number of bulls with giant fibres (GF) and the size of GF was greater in more intensively growing bulls (P<0.05) and it probably determined the higher values of tenderness and acidity of biceps brachii muscle. It should be noticed that the increased growth rate of bulls may result in poorer quality of meat.

The expediency of using the probiotic drug Biolax-U in the rations of lactating and dry cows of Black-and-White breed has been studied and scientifically proved. The influence of this drug on the morphological and biochemical parameters of animal blood has been determined. The composition of the probiotic drug Biolax-U consists of eight strains of a balanced complex of living lactic acid bacteria, yeast and actinomycetes, as well as biologically active substances. For experimental studies conducted on 2 groups of cows have been selected by the method of pairs-analogs, the influence of feeding of feed have been prepared with the use of the microbiological drug with probiotic action Biolax-U on feed consumption, morphological and biochemical changes in blood has been studied. Analysis of the rations of cows indicates that the content of calcium, phosphorus, magnesium, sulfur and trace elements such as manganese, copper, zinc and cobalt in the feed has been reduced. It has been found by studies that the use of probiotic drug Biolax-U had the positive influence on the feed intake, digestibility and better assimilation of feed nutrients and contributed to the improvement of blood morphological and biochemical parameters. For example, in animals of the experimental group hemoglobin has increased by 3,6 % (Р < 0,05), red blood cells by 10,1 (P ≤ 0,05), the content of leukocytes by 4,43, carotene by 9,6, glucose by 3,4; reserve alkalinity by 15,6, calcium by 19,4 (P ≤ 0,01), and phosphorus by 18,4 % compared with the control group of animals. During the lactation significantly improved hematological parameters including alkalinity reserve by 5,11 %, calcium level by 11,1, phosphorus by 8,6, hemoglobin by 14,2 %, the content of erythrocytes by 12,3, leukocyte by 3,86, and carotene 11,1 % against the parameters of animals of control group. The improvement of morphological and biochemical parameters of blood of cows indicates about stimulating effect on hematopoiesis and the general clinical condition of animals that contributes to the improvement of metabolic processes when using feed prepared with the use of microbiological drug with probiotic action Biolax-U.
