The aim of our research was to conduct a retrospective analysis and to study the current state of the subjects breeding Znamensk intrabreed type of Polessian Beef breed and to assess main economically useful traits and genealogical structure. Material and methods. Research of productive and economic activity of breeding farms has been carried out based on the electronic database of State Register of Breeding Subjects in Livestock for 2003-2016. Analysis of the number of breeding animals, distribution of cows by age, animals’ live weight, milk (as a calf’s live weight at the age of 7 months) and reproductive abilities has been performed based on breeding account (form №7-myas) for 2010, 2012, 2014, 2016. Results of research. The most breeding farms meet the minimum requirements of the target standard of Znamensk intrabreed type on the main quantitative traits of animal productivity. "Kolos" АLLC, Kirovograd region and «Agrikor Holding" LLC, Chernihiv region were the most numerous. High realization of genetic potential of meat productivity (daily gain of live weight above 1000 g) was observed at animals in «Kolos» АLLC and «Sharivske» PE. There have been sold 222 head of the breeding youngsters for 13 years. The greatest number of animals was observed according to annual reports in 2012. It can be explained by the number of subjects conducting the selection and breeding work with the intrabreed type. The share of cows did not exceed 43.0% (2012), bull – 1.5% (2010), calves of different gender and age groups – 66.1% (2014). 85.5% of all the available breeding stock (5369 head) was approved and 67.8% corresponded to elite and elite-record classes. Live weight of the approved cows has increased by 7.5% at the age of 3 years, 9.7% at the age of 4 years and 11.1% at the age of 5 years since 2010. Differential for live weight of cows at the age of 4 and 5 years was 9 and 11 kg on the average. There was adequate number of animals, live weight of which was in a wide range, that is from 551 kg and above. So, such cows were 111 head in 2010 and 234 head in 2016. These cows realise genetic makings of high productivity sufficiently and they are material for selecting the best representatives of Znamensk intrabreed type. Gradual increase of milk ability was noted from 2010 till 2016 after the first calving by 13.7%, the second – 12.2, the third – 11.7, and by 11.9% on average. Differential for milk ability of cows was 5 kg (2010, 2012), 11 kg (2014) and 2 kg (2016) on average. Average calving interval of cows for the period are oscillatory in nature and didn’t exceed 420 days during 2010-2014. Gradual increase of age at first calving of heifers by 101 days was observed from 2010 to 2014 with reduction to 824 days for next two years. It should be noted violation of course of cows’ and heifers’ calvings, it was 29 and 36 cases in 2010 and 2012 respectively, whereas in subsequent periods, these values were significantly lower or non-existent. It may indicate a high level of veterinary services and compliance of technologies of feeding and management. Efficiency of beef cattle-breeding depends on the growing of calves. Analysis of the results shows that live weight of calves at the age of 210 days has increased in each investigational year. The values are oscillatory in nature between 8 and 15 months. Sexual dimorphism was confirmed and proven – bull-calves had higher growth rate compared to heifers. Significant reduction in the livestock number of the approved bloodlines and their absence in some cases (Radyst 113 and Darovanyi 400) was observed. This is due to the increased share of Polessian Beef and Charolais bulls used for reproduction. There were 139 cows, 27 heifers and 13 calves in group belonging to Polessian Beef and Charolais bloodlines in 2012, whereas in 2014, 281, 193 and 18 respectively, representing 81% of the total population. Conclusions. The research revealed that livestock of the type were concentrated in «Agrikor Holding» breeding farm, Pryluky district, Chernihiv region with a total of 922 head, including 348 cows. Productivity of animals by the valuation results at the beginning of 2016 (live weight, milk ability, reproduction) significantly increased. Current genealogical structure of Znamensk intrabreed type was represented by bulls belonging to Polessian Beef and Charolais bloodlines, share of which was 81%.

For the last years significant reduction of breeding farms has led to decrease in the number of populations and these trends are particularly concerning beef livestock, competitiveness of which is lower compared with dairy cattle-breeding. There is observed to decrease not only number of indigenous populations, which aren’t able to compete on productivity, but also native specialized cattle. So, population of Ukrainian Beef breed declined 1,5 times (8 breeding farms, 2733 head, 1135 cows on January 1, 2010 vs. 3, 1824, 665 respectively on January 1, 2016), Polessian Beef breed – 2,2 times (27 breeding farms, 8904 head, 3705 cows on January 1, 2010 vs. 10, 4113, 2157 respectively on January 1, 2016), Ukrainian Grey – 1,2 times (4 breeding farms, 1075 head, 437 cows on January 1, 2010 vs. 2, 903, 341 respectively on January 1, 2016).The reality of the recent years indicates that some native beef cattle breeds can be considered as local and as needing conservation in the nearest future. Thereby, the aim of our work was to study dynamics of growth, productivity and reproductive ability of breeding stock of Ukrainian Grey breed compared with Ukrainian Beef, Polessian Beef having been created with its participation, and Blonde d'Aquitaine – a foreign specialized beef breed being bred under the same conditions. Materials and methods.The investigations were carried out at the herds of SE «Polyvanivka» Research Farm», Magdalynivka district, Dnipropetrovsk region and AF «Klen», Zhovkva district, Lviv region at breeding females of Ukrainian Grey (n = 279), Blonde d'Aquitaine (n = 42), Ukrainian Beef (n = 159) and Polessian Beef (n = 100) breeds. The indicators of growth rate, reproduction, and productivity were analysed based on data of zootechnical primary account registered at breeding farms. Results of research. Comparison of averages by a group found that the Ukrainian Grey animals were characterized by slightly lower figures of live weight at all the investigated ages. Under the same growing conditions, live weight of the Ukrainian Grey animals at the age of weaning was 14 kg (P < 0,001) less compared with the Ukrainian specialized beef breed (Ukrainian Beef) and by 19 kg (P < 0,001) less compared with the French specialized beef cattle (Blonde d'Aquitaine). The results are quite predictable that the indigenous breed isn’t able to compete with specialized beef cattle. The Ukrainian Grey animals were characterized by lower figures of average daily gain of live weight almost for all the investigated age periods with the greatest difference from birth to weaning – 56 g (P < 0,001) compared with Ukrainian Beef and 79 g (P < 0,001) compared with Blonde d'Aquitaine. The Ukrainian Grey heifers at the age from 1 to 2 years were characterized by almost the same growth rate as Ukrainian Beef and Polessian Beef contemporaries and predominated slightly over Blonde d'Aquitaine. The greatest difference was observed between milk ability of the Ukrainian Grey and Polessian Beef cows within 15-21 kg (P < 0,001). Predominance of cows of other studied breeds over Ukrainian Grey was 13 kg (P < 0,001) after the 1st calving, 14-19 kg (P < 0,001) after the 2nd calving and 11-15 kg (P < 0,001) after the 3rd calving. Reliable differences in calving interval weren’t revealed between Ukrainian Grey and Ukrainian Beef, Blonde d'Aquitaine (except for calving interval between the 1st-2nd calving). Comparative analysis of age repeatability of live weight revealed that gradual reduction of repeatability coefficient with each distance from the age of 210 days or 1 year was characterized for the animals, kept in "Polyvanivka" breeding farm. So, the highest age repeatability was observed at adjacent periods – 210 days-1 year, 2-3 years. Higher levels of age repeatability of live weight were found at the Polessian Beef and Blonde d'Aquitaine animals. The results of research of Ukrainian Grey cows’ productivity should not be assessed pessimistically, because productivity for indigenous and local breeds has never been the main traits in their preservation. It is studied to monitor their state. Conclusions. So, indigenous Ukrainian Grey cattle are inferior to all the investigated beef breeds by productivity that caused by its triple-purpose specialization with working ability at the first place in the past. The significant high and middle levels of age repeatability indicate the possibility of effective selection of Polessian Beef and Blonde d'Aquitaine heifers on live weight at weaning (210 days), whereas for Ukrainian Grey and Ukrainian Beef animals at 1-years’ age. No reliable correlation of live weight with milk ability was found at the Ukrainian Grey, Polessian Beef, and Blonde d'Aquitaine cows and inverse correlation of live weight at 4-years’ age with milk ability after the 2nd calving – at the Ukrainian Beef cows.

Based on the analysis of breeding work materials at the Russian meat cattle breeding, the importance and effectiveness of scientific breeds’ zoning was shown. Meat cattle which is bred at the Russian breeding farms is not worse than foreign one in terms of growth intensity, live weight, milk content and meat qualities. Multi-breeding is an objective necessity for the Russian Federation with its diverse natural and economic conditions. In 57 regions of the country, a comprehensive assessment of breeding and productive qualities of meat cattle is carried out. Strengthening the breeding base and matching the placement of cattle breeds to the natural and economic conditions of the regions is one of the most important conditions for the successful development of meat cattle breeding.

One of the ways of increasing level of animal economically useful traits is selection work with farm families. In pedigree cattle breeding of Ukraine families are a statistical component of breed genealogy. Among the main scientific works on working with families, it should be noted minimum number of female ancestors, proposed by D. T. Vinnichuk, to determine the breeding value, different categories, classification and techniques for evaluating related groups of females. The aim of our research was to analyse importance of farm families for genealogical structure of the breed. The research was on basis of data of primary breeding records at the herd of Volyn Beef cattle of “Zorya” breeding farm, Kovel district, Volyn region. Akula 102, Galka 37 and Galka 1537 families belonging to Krasavchyk 3004 bloodline, Smorodyna 613, Korona 2382 and Visla 1016 families – Tsebryk 3888 bloodline, Kalyna 212, Verba 1536 and Garna 536 families – Yamb 3066 bloodlines, Kazka 433, Galka 421 and Bystra 1124 families – Buinyi 3042 bloodline, Rozetka 1313, Arfa 599 and Bulana 943 families – Sonnyi-Kaktus 3307-9828 bloodline, and Palma 275, Desna 870 and Veselka 444 families – Mudryi 9100 bloodline were characterized. Belonging to a bloodline was determined by the father's side of female ancestors. Structural units of families: branches, branching with identifying the best individuals on breeding traits were submitted to identify the best combinations and successful use of closely related breeding. Comparing assessment of related groups of females on the main breeding traits belonging to Krasavchyk 3004 bloodline, it was noted that the cows of Akula 102 family predominated in live weight at 5 years’ age, milk ability and economic use duration, whereas the cows of Galka 1537 family – on traits of reproductive ability. Smorodyna 613 family of Tsebryk 3888 bloodline had high duration of economic use and cows’ live weight at 5 years’ age compared with Korana 2382 and Visla 1016 families with equal values of the exterior traits (height measures) and coefficient of reproductive ability. The families of Mudryi 9100 bloodline in terms of reproduction (calving interval, coefficient of reproductive ability) had the highest figures of cows’ milk ability and live weight. The cows of Bulana 943 family had a considerable predominance over representatives of Rozetka 1313 and Arfa 599 families of Sonnyi-Kaktus 3307-9828 bloodline by main economically useful traits. High indices of reproductive ability were noted in these families. Heifers of the families of Buinyi 3042 bloodline had high live weight at 18 months’ age at average values of milk ability and cows’ live weight at 5 years’ age. More equal figures of growth rate, exterior and economic use duration were observed in the cows of Kalyna 212, Verba 1536 and Garna 536 families of Yamb 3066 bloodline. Breeding by families in beef cattle breeding is an important element of selection, because it allows to evaluate not only related group of female ancestor, but also to analyse a successful combination with lines and purposeful use of closely related breeding by the best representatives of a breed.

Dairy cattle breeding is one of the leading livestock sectors whose purpose is to ensure the production of high quality dairy raw materials in volumes meeting the scientifically grounded standards of state food security and expanding the export potential of the agrarian sector. The purpose of our research was to study the status and prospects of dairy cattle breeding in the Kirovograd region. Material and methods of research. The research was carried out on the basis of the electronic database of breeding goals (including 2312 cows), official statistics and estimates of cattle of various breeds that are involved in the production of dairy direction in the breeding farms of the Kirovograd region. The analysis used zootechnical and statistical methods. The calculations were carried out using the software package "STATISTICA-6,1" Results. According to the research (2001–2018), the cattle population in the Kirovograd oblast decreased by a factor of 2.6. Thus, as of January 1, 2018, its number constituted 96.3 thousand heads in all categories of farms, 53.1 thousand of them were cows, the number of which also decreased by 2.4 times. Specific gravity of cattle population of farms remains significant and makes up 72.7%, and 80.6% in the livestock of cows. The largest number of cows of agricultural enterprises declined significantly. Thus, as of January 1, 2018, their number was 10.3 thousand goals, which is 4.7 times less than in the same period of 2001. In the households there is also a tendency for a permanent reduction of cows, the difference is, respectively, 37.0 thousand heads or 46.4% The development of dairy cattle breeding is characterized by two opposite tendencies: reduction of livestock of cows and increase of their productivity. Thus, in agricultural enterprises in 2010, compared to 2000, hopes per cow increased by 2.5 times, in all categories of farms by 1.8 times. In 2017, the increase in dairy costs in agricultural enterprises compared to 2010 amounted to 60.0% in farms of all categories 12.2%. The researches found that in the agricultural enterprises of the oblast as of January 1, 2018 there are 26256 head of cattle, including 10281 cows. The breeding part of the existing cows is 3.013 heads, 29.3% of the total number located in 10 breeding farms. The analysis of the genealogy structure showed that the experimental population of cows belongs to 18 lines and related groups of which the most numerous Chifa 1427381 – 20.4%, Starbuck 352790 – 20.1%, Henev 1629391 – 18.6% , Eleusis 1491007 – 11.2%, Family 267150 – 10.8%. Among the indicated lines, the lowest level of milk productivity was first-born cows. The 1491007, the milk of milk for 305 days of lactation was 4466 ± 99.8 kg, and the milk fat was 168.2 ± 6.5 kg. Analogues l Starbak 352779 was characterized by the highest milk productivity, its level was 5696 + 98.8 kg and 224.9 ± 9.7 kg, respectively. The difference in stomach was 1230 ± 140.4 kg (td = 10.2) and at the release of milk fat 56.7 ± 5.28 kg (td = 10.2) at P < 0.001. However, the latter were markedly less service life (125 against 168 days) and logically higher reproduction rate compared to other lines. An analysis of the intensity of the formation of live weight of young animals has been established for its highest growth in heifers of controlled herds in the period from 9 to 12 months. Thus, in animals of Ukrainian red breed, the growth rate of live weight during this period was 75 kg, Ukrainian red-shrimp 61 kg, Ukrainian black-and-white 73 kg, Holstein 76 kg. Accordingly, during this period, the average daily gain of live weight of young breeds of these breeds was 833 g; 678 g; 811 g, 835 g. The sharp fluctuations of average daily increments during growing periods, first of all, testify to the unequal conditions of growing and feeding young animals than the breed differences. In general, as a result of the analysis of the formation of live weight of heifers, a significant level of phenotypic variability was observed, which confirms sufficient genetic resources and preconditions for selection on the given sign. Therefore, proceeding from the above, in the long run, selection work for breeding improvement of cattle breeding farms of the Kirovograd region should be conducted in accordance with certain promising directions according to groups of breeds. Conclusions. A very important factor in the growth of milk production in the Kirovograd region is high-yield pedigree cattle. The main task on the way of bringing breeding cases in dairy farming to the modern level is the introduction of computer breeding records in breeding farms. This will allow to estimate in the near future bulls-pedigrees, which were used in the past in these farms, to allocate among them complex improvers for precisely the specific conditions and maximally attract them for reproduction. On the other hand, a reliable clogging of poor quality in the genetic sense of sperm production, which leads to negative consequences, will be posed. When establishing the assessment of the breeding value of bulls and developing a single plan of breeding and breeding work in the region, one can proceed to the next step of improving breeding and breeding business, introducing a progressive method of raising the breeding value of animals of large-scale breeding. As a result, the profit from the breeding of highly productive animals, well adapted to specific conditions, will significantly exceed the costs. At the same time, the proposed measures will allow the breeding business to be brought up to the modern world level and stimulate highly productive cattle breeding.

AbstractData from experimental programmes designed to investigate the effect of chemical structure of fats upon their apparent digestible energy (DE) value for pigs were subjected to regression analysis. For growing pigs, over the approximate live-weight range 30 to 90 kg, 25 data points were available, with fats evaluated having a range in the ratio of unsaturated to saturated fatty acids (U/S) from 0·66 to 15·67 and in free fatty acid (FFA) content from 8 to 818 g/kg. Sixteen data points were available for young pigs of approximately 12 kg live weight with a range in U/S from 0·62 to 5·71 and in FFA content from 54 to 756 g/kg. The wide range of values for U/S and FFA content had been obtained by blending different fats and, therefore, represented both the range and extremes likely to be found in the formulation of pig diets. Derivation of prediction equations for DE were based upon a series of non-linear regression analyses employing, in sequence, U/S, U/S + FFA content and U/S × FFA content. The DE offats could be predicted from U/S and FFA content with equations accounting for 0·802 and 0·768 of the variation in DE values for growing and young pigs respectively. The most appropriate equation for pigs of all live weights employed U/S and FFA content additively (U/S + FFA content). The equation for growing pigs was DE (MJ/kg) = 36·898 – (0·0046FFA (g/kg)) — 7·33e(–0·906U/S) and for young pigs was DE (MJ/kg) = 37·890 — (0·0051FFA (g/kg)) –8·20e(–0·515U/S). Comparisons revealed that differences between the two age groups, with lower values achieved with younger pigs, -were more pronounced the lower U/S and the higher FFA content of the fat.

Introduction. When creating the Simmental beef breed of cattle during many years carried out researches to study the effectiveness of the use of meat Simmentals of foreign selection in crossbreeding with cows of Simmental breed of domestic selection. Were created the herds of the desirable type by breeding "in themselves" animals, that meet the requirements of the target standard, formed a genealogical structure. Now carry out the work with related groups of cattle of the created Simmental meat breed, which are the basis for the creation of further lines, but the growth and development of animals of different related groups have not been sufficiently studied. Therefore, the study problems of growth and development of repair heifers of different related groups has not only theoretical, but also practical importance. The purpose of our researches was to study the dynamics of linear growth and weight development of heifers of different related groups of the created Simmental meat breed. Research materials and methods. The researches was carried out on heifers of different related groups of the created Simmental meat breed in PJSC "Dniprovske" of Boryspil district of Kyiv region. To analyze the growth and development of heifers were formed groups of animals depending on their belongings to related groups of 15 heads in each: I Group – Metz 5290; II – Achilles 369; III – Abricot 58311; IV – Huxla 19223; V – Hercules 8942 and VI – Signal 120. Research results. It was determined, that heifers of the II group, which belong to the related group of Achilles 369, by live weight at all ages of periods surpass to peers. Thus, at 18 months of age the advantage of heifers of the II group by live weight in comparison with to peers of the I, III, IV, V and VI groups was 4.1; 3.0; 5.0; 14.1 and 11.4 kg. In heifers of related groups Hercules 8942 and Signal 120, the coefficients of variability of live weight at birth in which were the lowest, and in the following age periods they little changed, therefore at 18 months of age in these heifers they were the highest, comparison with analogues, and was to 8.4 and 9.2%, respectively. When studying the exterior of heifers of different related groups it was determined, that newborn heifers of the I group, which belong to the related group of Metz 5290, surpass their peers in height indicators. Their the height at the withers and the height at the sacrum were 74.0 and 79.1 cm, which is 0.6; 1.3; 2.1; 3.2 and 2.6 cm and is 0.3; 1.2; 2.9; 3.6 and 3.2 cm more than in analogues of the II, III, IV, V and VI groups, respectively. The best indicators of latitudinal measurements had the heifers of the III group, which belong to the related group Abricot 58311. In heifers of this group the width of the chest was 17.6 cm, width in the hip joints – 21.8 cm, width in the hips – 18.1 cm, and width in the ischial tubercles – 12.6 cm. The depth of the chest and the girth of the chest behind the shoulder blades were the highest in heifers of the I group, which belong to the related group of Metz 5290. They were 32.2 and 79.6 cm, respectively. When analyzing the measurements of heifers at 18 months of age, it was determined, that the height indicators had advantage by heifers of the II group, which belong to the related group of Achilles 369. Their, the height at the withers and height at the sacrum were 124.5 and 129.8 cm, which is 0.3; 1.3; 2.5; 5.3 and 4.2 cm and is 0.9; 2.2; 4.1; 6.6 and 5.9 cm more than in analogues of the I, III, IV, V and VI groups, respectively. The best indicators of latitudinal measurements had the heifers of the III group, which belong to the related group of Abricot 58311, since they had increases of measurements width of the chest, width in the hip joints, width in the hips and width in the ischial tubercles for the period from birth to 18 months of age the highest comparison with peers. Such indicators as depth of the chest and the girth of the chest behind the shoulder blades were highest in heifers of the II group, which belong to the related group of Achilles 369. Their increases of measurements depth of the chest and the girth of the chest behind the shoulder blades for the period from birth to 18 months of age also were highest comparison with peers and were 35.5 and 94.2 cm, respectively. Conclusions. It was determined, that the animals of the related group of Achilles 369 at all ages of periods had a large live weight in comparison with their analogues. The lowest coefficient of variability of live weight at 18 months of age was in heifers of the related group Abrikot 58311 and amounted to 6.5%. Heifers of the related group of Achilles 369 had the highest indicators of the following measurements: height at the withers (124.5 cm), height at the sacrum (129.8 cm), depth of the chest (67.4 cm), girth of chest behind the shoulder blades (173.1 cm) and oblique length of body (146.4 cm). The highest latitudinal measurements were observed in the heifers of the related group Abrikot 58311. Thus, the width of the chest was 49.9 cm, the width in the hip joints was 42.2 cm, the width in the hips was 43.3 cm, and the width in the ischial tubercles was 29.2 cm. Heifers of the related group Metz 5290 had the highest half-girth croup (110.2 cm) and girth of metacarpus (18.4 cm). In general, heifers of all groups showed good energy of growth and a typical for beef cattle exterior.

Two randomised-block experiments have been carried out to examine the relative feeding value of wheat and barley as supplements to grass silage for finishing beef cattle. In each experiment unwilted, formic acid-treated silage was offered ad libitum and supplemented with 500 g soyabean meal and 50 g minerals and vitamins to 44 twelve month old bulls for 157 and 172 days in experiments 1 and 2 respectively. In addition 12 animals received 2.5 kg rolled spring barley (LB), 12 received 4.0 kg barley (HB) and 20 received 3.25 kg rolled wheat (W). Silage was offered once daily and concentrates twice daily in two equal meals.Eleven British Friesian bulls and thirty-three bulls which were Friesian x Continental beef breed were used in each experiment. They were initially 402 and 385 kg live weight in experiments 1 and 2 respectively. In both experiments the animals were housed and fed in groups of four in slatted pens. All animals were slaughtered at the end of the experiments to obtain carcass data.

In a market economy, the prime-cost of production is the most important indicator of the financial and economic activity of any economic entity. It is a cost estimate of all resources used in the production process of the industry: feed, animal protection products, materials, fuel, energy, fixed assets, labour, natural and other costs associated with its production and sale. The purpose of the work was to calculate the prime-cost of production when rearing of young animals in dairy and beef cattle breeding in the Kurgan region. The analysis has shown that according to the years of observations less than half of livestock products were produced in agricultural organizations of the region: meat – 36,3–38,6 %, milk – 29,3–30,6 %. Egg production in agricultural organizations was at the level of 13 %. The correct choice of objects of calculation and calculation units, as well as the use of special methodological recommendations for accounting production costs and calculating the prime-cost of products (works, services) in agricultural organizations allows us to more accurately determine the prime-cost in dairy and beef cattle breeding. Despite the great attention to the individual aspects of cost accounting and calculating the prime-cost of agricultural production, there is still a need and importance of a more detailed study and further improvement of accounting and calculation of meat and dairy cattle products. The prime-cost of the gain in the live weight of young cattle can be calculated by different methods, but at the same time the selected option must be fixed in the accounting policy of the organization.

The article presents the findings on the dynamics of the live weight of calves of various breeds in similar climatic conditions in arid regions of the Stavropol Krai of Russia and the steppe zone of Ukraine. It has been established that the live weight of calves of the Hereford, Kazakh white-headed and Kalmyk breeds when raised according to the traditional technology of beef cattle breeding when calves are sucked under cows up to 6-7 months of age, is in relationship with the milk qualities of mothers. At the same time, the live weight of the gray Ukrainian calves was interrelated regarding the live weight at birth and the feeding technology. A positive relationship was shown in the live weight of calves at birth and during their implementation at 15 and 18 months of age. Most effectively animals used pasture fodder in spring and summer. In an arid climate, it is more appropriate to breed specialized cattle belonging to the Hereford breed and then sell them for breeding in other farms in the region.

Meat Productivity

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.
