In the Irkutsk region, beef is obtained from all breeds of cattle. The main share is accounted for by cattle of black-and-white breed, the share of specialized meat breeds is only about 20% of the total volume of beef. Excellent taste characteristics due to the chemical composition of meat. The results of meat quality from the Kazakh white-headed and Hereford breeds testify to their high nutritional value, so the BKP level was 6.34 and 6.48, respectively. The comparing estimation of meat productivity and quality characteristics of meat was carried out. For these purpose the control slaughter was 18 months age. The data analysis revealed a high level of slaughter characteristics of meat bull-calves. The average pre-slaughter weight of one bull-calf of Kazakhskaya belogolovaya breed was 453,77 kg, Hereford breed – 470,21 kg. Differences was 3.62 %, with carcass yield– 53%, and slaughter – 56 %. Correlation of water and dry matter lies within 70/30. Bull-calves meat of Hereford breed contains more protein by 1/27%, fat-1.48, ash – 0.11%. Meat of Kazakhskaya belogolovaya bull-calves breed is somewhat inferior in quality characteristics.

The ’Silos’ software package was used to formulate diets for all of the animals involved in the study. Cows of the Holstein black-and-white breed were divided into three groups. They were fed grain and legume haylage conserved with the biological fermentation products ’Biosib’ and ’Silostan’. The milk samples were analysed for chemical composition and physico-chemical properties. It was found that compared to the control group the samples of milk obtained from the test groups contained more dry matter (by 0.08 % and 0.13 %), milk-solids-nonfat (by 0.04 % and 0.06 %), fat (by 0.04 % and 0.07 %), fat (by 0.01% and 0.03 %), lactose (by 0.02% and 0.03 %), energy value was larger by 0.56 kcal (0.77 %) and 0.98 kcal (1.35 %). The quality of raw meat was assessed after the control slaughter of the black-and-white bull calves aged 18 months. Before slaughter the animals were fed alfalfa haylage conserved with the biological fermentation product ’Biotrof’ at doses of 2, 4 and 6 l of the process solution per 1 ton of the grass. Compared to the control group the average meat samples obtained from the 1st-3rd test groups contained more dry matter (by 0.48-1.03 %), fat (by 0.29-0.84 %), protein (by 0.25.63 %), maturity rate was higher by 0.55-1.55 %, energy value per 1 kg of meat was higher by 155-436 kJ (2.03-5.70 %; P<0.05).

The research was carried out on the farms of the raw material zone of the Branch "Tikhoretsky Canned Meat Plant" of DANON RUSSIA JSC in two districts of the Krasnodar Territory. Experimental data on the productivity of bull-calves of dairy-meat black-and-white breed and its cross-breed with bulls of Kalmyk beef breed. In the "Rubin" farm of the Goryacheklyuchevsky district, the productivity of beef cattle of the Charolais breed was studied. In the study of raw meat for baby food, a comparative assessment of the quality and food safety of beef from black-and-white bulls; cross between black-and-white and Kalmyk breeds; Charolais breed was carried out. In terms of protein quality indicator (6.5), beef from Charolais bulls exceeded the rest (6.16 and 5.8). The Charolais breed has the best protein composition (19.8 g / kg of lysine, the limiting amino acid for the child's body). In terms of safety indicators, taking into account the maximum permissible levels of residual amounts of pesticides, toxic elements, antibiotics, meat raw materials from black-and-white bulls and a cross with the Kalmyk breed met the requirements of the interstate standard for raw materials for baby food.

We studied protein metabolism in Holsteinized black-and-white cattle. The researches were conducted in the Kuzbass at OJC «Vaganovo». Blood sample was taken from each cow, according to generally accepted of methods and analyzed in the laboratory of biochemistry from Novosibirsk State Agrarian University by using standard kits of biochemical studies on a biochemical semiautomatic analyzer Photometer 5010 V5 +. The indicators of protein metabolism were established in the blood serum of Holsteinized black-and-white cattle in average values; creatinine was characterized by the lowest phenotypic variability. The greatest positive relationship was found between albumin/globulin coefficients and albumin (r = 0.765). The reference intervals were calculated for cows of the 3rd lactation of the Holsteinized black-and-white breed with a high level of milk productivity (9-10 thousand kg): total protein 62.02-87.58 g / l; albumin 21.05-36.09 g / l; urea 2.2-4 mmol / l; creatinine 50-71 μmol / l; albumin-globulin coefficients 0.35-1.16. The data obtained can be used for assess the interior of animals.

The results of the study of milk productivity and lactation rates of fi rst-calf cows are presented. The research into fi rst-calf cows of black-andwhite Holstein breed, belonging to sire lines of Wis Ideal 1013415 and Refl ection Sovereign 198998 was conducted in 2018 in Novosibirsk region. The number of cows under study was 64, the period of the study covered 305 days of lactation. Monitoring of milk production, milk fl ow intensity, fat and protein content was carried out monthly. The research materials were analyzed for groups of cows depending on their sire line and productivity for single and daily milk yield, fat and protein content, and dynamics of milk ejection for the fi rst 3 minutes of milking. The highest daily milk yield in both lines was observed in the second month of lactation. In the fourth and fi fth months of lactation, the average daily milk yield of Refl ection Sovereign cows was signifi cantly higher (р < 0.001) than that of their peers of the Vis Ideal line, by 1.3 kg. During the lactation period, the productivity of the Vis Ideal and Refl ection Sovereign cows was almost the same: milk yield – 8296 and 8220 kg, fat content – 4.02 and 4.06%, protein – 3.36 and 3.35% and milk fl ow intensity – 2.70 and 2.78 kg/min, respectively. In the second and third months of lactation, cows of both lines had a decrease in the content of fat, protein and intensity of milk fl ow with a gradual increase in these indices in the fourth and fi fth months of lactation. First-calf cows of the black-and-white breed of Canadian selection of different sire lines showed a high level of milk productivity and proved to be suitable for further breeding work.

The materials of the long-term (2008–2018) research into the reproductive function of cattle of the black-and-white breed of Baikal type in Irkutsk region are presented. The influence of the age at the first insemination and live weight on cows’ milk productivity, lifelong productivity and productive longevity was studied. The experiment was conducted on the basis of materials from the breeder-farm for breeding cattle of Baikal type on the groups of cows of different ages: up to 14–20 months and older. Cows inseminated at 16 months (7917 kg) had the best milk yield in the first lactation. The largest milk yield was obtained from inseminated cows with live weight of 401-410 kg. Milk production of these heifers was 7902 kg in the first lactation, 8792 kg – in the second and 8710 kg – in the third. It was revealed that age of cows and their live weight at the first successful insemination had a positive effect on the lifelong productivity and productive longevity of cows. Cows whose age at the first successful insemination was 15 or 16 months had a longer duration of productive use (productive life span of animals was 2561–2558 days, respectively). The highest lifelong productivity (34379–34585 kg) was obtained from the cows of this group. The economic efficiency of lifelong milk production was determined depending on the age of the first insemination. The highest lifelong milk productivity was obtained from cows, which were first inseminated at the age of 15–16 months. The largest revenue from sales of additional products was also received from the cows of this group (366,058–370,480 roubles per head). The results obtained allow to develop effective methods for increasing reproductive capacity of cattle.

The analysis of the literature data shows that there is not enough information on the enrichment of the ration of cows of Black-and-White breed with a balanced feed complex Felucen K 1–2 that has caused the relevance of our researches. The purpose of the research was to increase the productive qualities of cows Black-and-White breed when using different doses of the balanced feed complex Felucen K 1–2 in their ration. The studies have been carried out in the Southern Urals, the optimal dose of use of feed complex Felucen K 1–2 that enhance milk productivity of cows of Black-and-White breed. According to the scheme of the experiment cows of the 2nd, 3rd and 4th experimental groups have been additionally fed to main ration 300 g, 350 and 400 g of the balanced feed complex Felucen K 1–2, consisting of vegetable protein and fat, easily fermentable carbohydrates, high-purity sodium chloride, macronutrients, trace elements, and vitamins. Animals of the 1st group have been served as control and complex Felucen have not been received. Studies have shown that cows of the 1st control group used less dry matter, EFU, metabolic energy, digestible protein, crude protein, crude fiber, and crude fat than their experimental herdmates. Thus, the superiority of cows of the experimental groups over the herdmates of the 1st control group in terms of EFU was 93,1–231,2 kg; metabolic energy – 933,7–2314,7 MJ; dry matter – 9,0–125,8; digestible protein – 8,9–29,7; crude protein – 4,6–18,3; crude fiber-13,1–48,4; crude fat – 11,6–21,0 kg. Animals of all experimental groups in comparison with the control group exceeded in terms of milk yield for 305 days of lactation by 435,2 kg or 6,60 % (P < 0,001); 814,4 kg or 12,34 % (P < 0,001); 684,1 kg or 10,37 % (P < 0,001); for 100 days of lactation – by 98,7 kg or 4,28 % (P < 0,001); 191,0 kg or 8,29 % (P < 0,001) and 167,8 kg or 7,28 % (p<0,001), respectively. The use of Felucen K 1–2 feed complex in the rations of lactating Black-and-White cows has shown its effectiveness, which has affected the feed consumption and effectiveness of their use, hematological indicators, the level of milk productivity and milk quality. From an economic point of view the dose of 350 g of balanced feed complex Felucen To 1–2 per animal per day is more reasonable.

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%.

Introduction. In 1997, Valeriy P. Burkat proposed by one of the methodological and organizational approaches to creating Simmental Beef cattle, to launch a series of experiments to study effectiveness of Simmental crossing with other breeds and to study the best combination for interbreed industrial crossing. The studies of comparative determination of meat quality at crossing of Simmental with specialized beef breeds found that these hybrids were well fattening and they had highly meat productivity. The methods of studying fattening and meat qualities of cattle recommend to conduct slaughtering and processing animals at meat processing plants, because under these conditions the standards for assessing meat productivity of animals and quality of their carcasses can be followed exactly. Compliance with instructions, recommendation for processing animal carcasses under such conditions and obtaining research results will be comparable with the slaughter of animals of different breeds, because all technological methods and sampling are conducted by specialists. General rules for testing laboratories for determination of quality parameters of agricultural raw materials and products under market conditions require the following: availability of specialists, a plan of sampling and the fastest transportation of them to place of laboratory testing, determination of research methods and conducting specific research, identified according to program (task) with followed analysis. Materials and methods. Experimental samples were the longest back muscle sampled from refrigerated right half-carcasses of bull-calves at the age of 12 months and 16 months. The animals were obtained from Black-and-White cows (BW) and bulls of Ukrainian Beef (UB), Volyn Beef (VB), Polesian Beef (PB), Simmental (S) breeds, grown in "Polesia", Ovruch district, Zhytomyr region. The control slaughter of experimental animals, followed deboned half-carcasses, was conducted by experts of Ovruch slaughterhouse, Zhytomyr region. The samples of the longest back muscle were taken at 9-12 ribs of refrigerated half-carcasses of clinically healthy bull-calves. The samples of muscle were labelled and fixed in a 10% solution of neutral formalin, cross sections were obtained using freezing microtome, histological specimens were produced by the method of colouring the muscle fat, performing a series of research works to enhance and improve existing methods for obtaining excellent results. Microscopy, morphometry and microscopic photography of histological sections of the longest back muscle were carried out using biological research microscope (MBI-6), division of muscular fibers by their size was conducted via ocular grid. Analysis of research results was statistically processed on a PC. Results. Based on the results of the experiment the higher live weight before slaughter was at bull-calves obtained from crossing with Simmental and Polesian Beef bulls, 304 kg and 285 kg, respectively in these groups, which was 53 kg and 72 kg more compared with animals of the same age of Black-and-White dairy breed. It is obvious that the formation of meat productivity from early age is associated with belonging to breed, specific soil and climatic and economic conditions at that time. All the cross-breeds of the research groups had better live weight before slaughter and weight of pair and chilled carcasses. But the greatest bone weight had animals of the same age of two research groups – ½PB½BW and ½UB½BW, respectively 16,8 kg and 15,8 kg. It is because of blood of Charolais bulls and consolidated trait of angularity during the selection. The highest live weight before slaughter had half-blooded genotypes with Simmental and Polesian Beef – 354 and 343 kg; it was slightly below compared with the target breed standard. The largest weight of pair carcasses had genotypes ½S½BW and ½PM½BW – 194 ± 6,2 and 193 ± 5,0 kg, the highest meatiness index had Volyn Beef counterparts at the level of 4.3 units. Medium muscle fibers (21-40mkm) had the highest share, from 72.4 to 43.6%, at the investigated bull-calves at the age of 12 months. Morphological structure of muscle of bulls at 16 months of age showed that average diameter of fine fibers at the animals of meat productivity was greater – 18.1mkm in combination with Simmental, 18.3 and 18.5 mkm – with Ukrainian and Polesian Beef against 17,9 mkm – at the counterparts of Black-and-White breed. The share of fine fibers was very high (15.3%) at the bull-calves of genotype with Ukrainian Beef against 7.3% and 7.2% – with Polesian Beef and Simmental. Some fat deposition and the small number of fat cells, located mainly around blood vessels, were observed in the longest back muscle of Black-and-White dairy bull-calves at the age of 12 months. Such changes in the number of fibers and size of their diameters, to some extent, affect the quantitative (meatiness index) and qualitative (the number of intramuscular fat) productivity characteristics of the investigated animals. Conclusions. Trend towards more intense growth and accumulation of muscle and fat was revealed at the researched bull-calves of meat productivity. Formation of economically useful traits on meat productivity of bull-calves depends on age, breed, genotypic and phenotypic factors. The results of histological studies indicate that internal structure of the longest back muscle and the ratio of different types of muscle fibers (thin, medium, thick), show breed and age features of meat productivity formation at bull-calves.

Positive Results

It was assumed that the industry of beef cattle breeding being created in the Krasnodar Territory would meet the needs of the population in beef. Due to the fact that there are not enough beef cattle, dairy bulls are raised and fattened. Positive results are obtained in the case when, along with an increase in the number of the fattened livestock of animals, their intensive rearing and feeding is introduced. In our studies, with intensive rearing and fattening of the Holstein and Black-and-White bull calves, for the entire 14-month period of growing and fattening, average daily gains were obtained at the level of 1200 g, and the gross weight gain was more than 500 kg. According to the results of the slaughter of experimental bulls at the age of 14 months, we found that the Holstein bulls reliably exceeded the black-and-white bulls of the same age in all the studied parameters.

The purpose of researches is increase of meat efficiency of bull-calves of black-motley breed through the use of canned green mass of alfalfa with Laxil and Silostan when harvesting haylage. The results of the evaluation of the effect of alfalfa haylage harvested with preservatives on the efficacy of bioconversion of nutrients and energy rations in meat products. Scientific and economic experience held in the SEC-farm «Alga» Chekmagushevsky district of the Republic of Bashkortostan. There are three trench silage from alfalfa. In one of them the food was laid with the application of the preservative Laxil, the second – and third Silostan – no preservatives. Laxil preservative was added at the rate of 1 liter per 15 tons of green mass, Silostan – 1 liter to 150 tons. The object of research was 45 bulls of black-and-white breed at the age of 9 months, of which three groups were formed: control and two experienced. Gobies control group received silage of alfalfa harvested without preservatives, and the animals of I and II experimental groups – silage, preserved by Laxil and Silostan. For studying of meat productivity and quality of meat of test bulls control slaughter of 3 bulls from each group was carried out. The results of the study indicate the superiority of calves of the experimental group over their counterparts from the control groups both in vivo and post-slaughter parameters. The results of the evaluation of the transformation of protein and energy feed in the production of bulls compared groups when grown for meat indicate that in the body of young I and II experimental groups were deposited a little more protein compared with peers from the control group.
