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.

The research was conducted to compare bulls and castrates in relation to the morphological composition of carcasses, the yield of beef suitable for the production of baby food products, and the quality and safety of raw meat. The research was based on the results of monitoring the safety of the environment, feed, and meat raw materials during the growing and fattening of steers with a meat productivity direction. The pre-slaughter weight and the yield of lean beef of 16-month-old Hereford bull-calves are higher in comparison with castrated animals of the same age, by 6.4 and 1 %, respectively. The muscle tissue of castrates contained 11.5 % of fat, and bulls 9.7 %. The protein content in the longest muscle of bulls was 19.8 %, and in castrates-17.0. The amount of fat beef that is not suitable for baby food is higher in castrate carcasses by 4.7 % compared to bull calves. A high protein quality index of the longest muscle of bulls (6.5) indicates a higher biological value of beef compared to meat from castrates (4.1). In terms of the content of residual amounts of pesticides, toxic elements, and antibiotics, the meat of castrates and bulls of the Hereford breed had no significant differences.

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.

As a result of the researchers found a positive effect of new feed additive on the growth rate, the qualitative indicators of meat fattening. It was found that the effect of feed additives on the productivity increased with increasing doses of feed additives from 100 to 300 g per head. Thus, at the age of 18 months, the bulls of the first experimental group surpassed the control analogues by 3.86, the second – by 5.53 and the third – by 6.42% and the average daily increase by 7.50, 11.63 and 12.45%, respectively. On the basis of the control of the slaughter was revealed that the weight of the paired carcasses in calves from the experimental group was higher than that of peers, not consuming the Supplement, of 5.82-of 9.91%, and their output is up 0.09 to 0.86 percent. At the output of the pulp of the bulls of the experimental groups exceeded the control analogues by 0.72-1.05%. The meat index of their carcasses was, respectively, higher by 0.25-0.36. In average the sample of the flesh of the carcasses of young animals who consumed the study Supplement contained more protein compared with the control 0,28-0,57% fat, respectively 0,68-1,19%. The influence of feed additive and on the content of amino acids in meat was revealed. Thus, essential amino acid tryptophan in the longest muscle of the back of the bulls of the experimental groups was higher by 1.58 – 2.87% and protein quality index-higher by 0.37-0.63. The flesh of the carcasses of calves of the experimental groups had higher technological properties. The moisture-retaining ability of their longest back muscle was higher than that of analogues of the control, by 2,05-2,22%, the fading – lower by 2,04-2,41%. In the body of young cattle, consuming feed additive, protein was postponed more than in control, by 8,67-14,85% and fat – respectively by 11,96-21,44%. The conversion rate of protein they were higher by 0.78-0.86%, energy - respectively 0.67-1.06%. The level of profitability of beef production in the experimental groups was higher than in control at 4, 18-of 1.29%.

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.

Quinoa Flour

Quinoa is a promising raw material for the production of foods with high nutritional quality. This study used quinoa flour (Chenopodium quinoa Willd.), egg white, and yucca starch to obtain an extruded pasta. By means of a proximate analysis, the nutritional content of the raw materials, uncooked and cooked pasta, was evaluated. The effects of quinoa flour on the protein composition, physical properties (color, texture, loss through cooking, water absorption, and swelling indices), moisture, DSC, and SEM were evaluated through its comparison with a commercial pasta (control) formulated with quinoa (PCQ). The values obtained during the study were subjected to a simple analysis of variance (ANOVA) to determine the interaction between the factors and the variables by using a statistical program. Incorporation of quinoa flour in the formulations (F1, F2, and F3) increased notoriously the protein content ( p < 0.05 ) and decreased the carbohydrate content, and no significant differences were observed for lipids and ash. The energy value increased due to the essential amino acids present in quinoa. The values obtained for L ∗ , a ∗ , and b ∗ increased with the increase in quinoa flour, and significant differences for b ∗ ( p < 0.05 ) were attributed to the characteristic color of quinoa, drying time, and moisture content. The lack of molecular interaction between starch and protein due to the conditions used in the extrusion process influenced the decrease in rupture strength, increase in the water absorption and swelling indices, and losses due to cooking (8 g/100 g) within an acceptable range. Consequently, affected by the enthalpy of fusion, the starch granules of the quinoa flour did not gelatinize, as observed in the SEM micrographs. The results obtained and the parameters used in the extrusion process influenced the characteristics of the pasta, indicating that quinoa flour is a promising raw material for obtaining gluten-free products.

The article discusses the results of a study of the effect of the use of biostimulants Biosvet made by the Filatov method from plant materials of foreign origin, and Megasvet made by the same method from domestic plants on the productivity and quality indicators of milk of Ukrainian black-and-white cows. For the study 30 cows with a productivity of 5000 - 5500 kg of milk per lactation were selected, which were divided into three groups of 10 animals each. The cows of the control group (C-1) in order to prevent the effects of stress from injections were injected subcutaneously in the neck with a physical solution in an amount of 15 m. The cows of the first experimental group (E-1) were injected with the biological product Biosvet 15 ml each, and the cows of the second experimental group (E-2) received the biostimulator Megasvet developed by us in the same amount. Four periods were identified in accordance with the season: autumn, spring, summer and autumn, Injections were given at the beginning of each period, Milk productivity and quality indicators were determined every ten days. The experience lasted from September 2020 to August 2021. As a result of the study it was proved that the use of biostimulants made from raw materials of plant origin has a positive effect on both productivity and quality indicators of milk in cows of the Ukrainian dairy black-and-white breed. The results of the use of biostimulants prove the higher efficiency of the biological product Megasvet in comparison with the biological product Biosvet. The use of Megasvet provides an increase in the productivity of cows in comparison with the use of Biosvet in the range from 5.72 % to 7.02 %, depending on the period of the year. On average per year the daily productivity in the second experimental group of cows, where Megaslight was used made up 6.35%. It was higher than in the first experimental group, where Biosvet was used. The use of Megasvet was more effective than Biosvet and in determining the quality indicators of milk, namely: fat content the presence of milk fat and protein content in milk.
