Introduction. In the structure of meat cattle breeding in Ukraine already a long time the leader in the number among of breeds of foreign origin there is a Aberdeen-Angus. This breed, due to its high manufacturability, is intensively used as a genetic material in the breed-forming process and increase the production capacities of the pedigree base of cattle breeding. At one time, the most intensive works on the development of the breed was conduct on the basis of the SAE "Main Breeding Center of Ukraine". Thanks the validity state support was organized the estimating of bulls for their own productivity and quality of descendants, was formed a bank of deep-frozen sperm and embryos, were created informative electronic card indexes of individual data of pedigree animals. This determines the expediency of analyzing the features of the formation of the genealogical structure of the population of the Aberdeen-Angus breed on the basis of the study of individual herds, which becoming the purpose of this work. The purpose of this work was to investigate the genealogical lines and families in the herd of Aberdeen-Angus breed in SAE "Main Breeding Center of Ukraine". Research materials and methods. The study of the genealogical structure was carried out on the basis of data primary zootechnical accounting in the format of SMDC "Orsek-M", expeditionary examination of the herd and the results of a comprehensive individual estimating of animals. Biometric processing of data was carrying out according to the method of N. A. Plokhinsky with using the software Microsoft Excel. Research results. As of 01.01.2021 year, in the herd of the enterprise total accrued of 155 heads, including 84 cows, which now fertilization of the method of natural mating bulls, purchased from the LLC “Ratnivsky Agrariy”, which obtained by method of artificial insemination of high-producing cows of the 2nd and older calves sperm of bull of Team Z Pecina 4031. Now the uterine stock of the studied herd belongs to the lines Southom Extr – 29 heads, Raito Iver 865 – 18 heads, Villabar 85 – 8 heads, Raito B 1567126 – 7 heads, Vetonk 2446 – 5 heads, Ilinmer Led 173 – 4 heads, Brialhill Sauzerner – 2 heads and the related group Team Z Pecina 4031 – 11 heads. The age of cows fluctuated from 3.1 to 19.2 years, and in the average be 9.8 years. The oldest cows belongs to the lines Raito B 1567126, Brialhill Sauzerner and Ilinmer Led 173, the youngest – to the related group Team Z Pecina 4031 and to the line Vetonk 2446. In the studied herd total detected 23 potential ancestors, which have living descendants of female sex. The most numerous are the families of K. Pride 11212597 – 9 descendants, E. Pride 11153487 – 8 descendants, K. Vessi 10887560 – 7 descendants. The families of Erika 3200797288, Kornela 3200797248, Sara 11756665 and Sandy 951931 presented 5 descendants of female sex of different generations. The minimum age of more than 10 years have the representatives of families of K. Erika 10240733, Beauty 10767437 and Elbe 3200797255, and the maximum age from 18 to 19.5 years – the representatives of families of K. Erika 10240733, Elin 10679739, E. Pride 11153487, Gemmer 10189403. The lowest and the highest average live weight had the newborn heifers the family of Kornela 3200797248 – 24.0 ± 1.7 kg, and the family of E. Pride 11153487 – 33.2 ± 1.5 kg, respectively. The average live weight of newborn heifers in other studied families was following: K. Pride 11212597 – 25.1 ± 0.4 kg; Erika 3200797288 – 28.6 ± 1.6 kg; K. Vessi 10887560 – 29.5 ± 1.5 kg; Sandy 951931 – 30.4 ± 1.6 kg. The average daily gain of live weight of heifers for the period from birth to 12 months of age fluctuated from 615 to 750 grams. The highest and the lowest average live weight at 12 months had the heifers the family of E. Pride 11153487 – 307.0 ± 19.7 kg and the family of K. Pride 11212597 – 249.2 ± 8.5 kg, respectively. Almost identical average live weight had the heifers the families of K. Wessie 10887560 and Kornela 3200797248 – 266.1 ± 11.14 kg and 266.6 ± 6.1 kg, respectively. The age of the first insemination fluctuated from 17.6 months in heifers the family of Erika 3200797288 to 21.4 months in heifers the family of K. Vessi 10887560. The highest average live weight at the age of the first insemination had the heifers the family of Sandy 951931 – 364.7 ± 20.6 kg, and the lowest – the heifers the family of Erika 3200797288 – 303.0 ± 8.8 kg, due to the younger age of their first insemination. Conclusions. Considerable narrowing of the genealogical structure of the modern herd of Aberdeen-Angus breed in SAE "Main Breeding Center of Ukraine" provoke the full absence representatives such classical lines as Ideal 3163, Power Play 8974207 and Showshoun 548. Due to the expansion of the related group Team Z Pecina 4031 will increase the genetic variability, reorganize age structure the uterine stock and direct zootechnical work with families to improve the parameters of individual growth and development of animals.

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.

Daily Gain

In dairy cattle breeding, selection and breeding work is widely used in order to transfer the pedigree qualities of parents to the offspring and obtain highly productive young animals. In this regard, in the conditions of «Enbek» LLP in the Akmola region, the growth and development of young Simmental breed depending on the origin was studied. Live weight of Litera line young animals at birth was 33.4 kg, at the age of 6 months-174.9, 12 months-251.8, 18 months-387.1 kg, respectively, Wildfang bull 32.0 kg, 165.5 kg, 251.3 kg, 378.6 kg. The average daily gain between the ages of birth and 6 months was increased. With age, the body parameters, height at the withers, increased from 104.3 cm and 103.5 cm to 125.4 cm and 123.9 cm, respectively, from 6 months to 18 months of young animals. According to the physique indices, we can say that the young Simmental breed is balanced. Only some deviations of the leggy index are observed from the optimal indicators. The index of legginess decreases with age by 7.7%, with indicators of 6 months – by 57%, at the age of 18 months-by 49.3%. The extension index for the period from 6 to 18 months increased by 10.5%, respectively, for 6 months-by 103.3%, for 18 months-by 113.8%. With age and an increase in live weight, the body of young animals lengthens, its width increases, the animal becomes deeper and relatively long-legged. Depending on the origin, we suggest using the Litera bull line, taking into account the growth and development of young animals, and the productivity indicators of bulls.

At the present stage of economic development of the Republic of Kazakhstan dairy cattle breeding should be competitive, highly productive and cost-effective, which contributes to ensuring the country’s independence from imports of dairy products. The formation of milk productivity of future cows begins with the preparation of cows for calving and the purposeful rearing of replacement young cattle, based on the achievements of scientific and technical progress, a systematic approach to the production of high-quality products. The researches have been carried out in the farm “Tauelsizdik” in the Eskeldinsky district in the Almaty region in the Republic of Kazakhstan. According to the results of the research, the average daily gain of live weight in 3 months of the post-embryonic period was 458,9±71,9 g in heifers have reared in narrow-sized pens, and 682,2±44,6 g in heifers have reared in group pens. At 3 months of age the live weight of heifers at rearing in narrow-sized pens has reached 76,5±2,5 kg in narrow-sized pens, and 98,3±1,7 kg in group pens (P < 0,001). The data of the experiment have convincingly shown the effectiveness of rearing heifers in group pens. The live weight of heifers at birth was 36,4±1,1 kg, at one month of age – 54,2±1,6 kg, at 2 months of age the live weight increased to 70,2±2,1 kg, at 3 months of age to 87,4±3,3 kg, at 4 months of age to 116,8±3,5 kg, at 5 months of age to 132,7±4,2 kg and at 6 months of age to 157,4±4,6 kg. The indices of lengthiness, chest, hip-chest and blockiness increased up with age, while the indices of high-leg and overgrown decreased down. For example, the lengthiness index has increased with age from 90 to 97 %, the chest index from 62 to 70, and the high-leg index has decreased from 59 to 54, overgrowth from 109 to 108 %.

The origin of an animal determines its productive and breeding traits. It is well known that in dairy cattle breeding a great importance belongs to sires, especially those belonging to the leading lines of Holstein breed. The productive indicators of heifers and fi rst-calf cows the off spring of diff erent lines of Holstein breed and daughters of diff erent sires have been presented in the article. The researches have been carried out under the environments of specialized enterprises for rearing of replacement heifers and milk production. Diff erences have been found in the daughters of diff erent sires in terms of live weight and milk productivity. Accounting for the weight growth of the daughters of sires has shown that the live weight of heifers between the lines Wes Ideal 933122 and Refl ection Sovereign 198998 was not a signifi cant diff erence. Daughters of sire # 511H11283 of the line Refl ection Sovereign 198998 in all age periods had a live weight, absolute and average daily gain, the growth rate of replacement heifers was higher than the daughters of other sires. At one year of age, their live weight was higher than that of heifers-daughters of sires # 11H11596, # 11H11565 and # 511H11422, respectively, by 4,1 % (P<0,001), 3,1 % (P<0,01) and 5,0 % (P<0,001). The daughters of sire # 511H11283 of Refl ection Sovereign line also had a higher yield of calves – 104,8 %. However, the largest number of heifers (75,7 %) has been obtained from the daughters of sire # 11H11565 of Refl ection Sovereign line. In terms of milk yield, signifi cant diff erences have been found between the lines and daughters of diff erent sires. Higher milk yield was obtained from the fi rst-calf cows of line Wes Ideal 933122 (12361±321 kg) and the daughters of the sire Mogul 11H011757 (13587±328 kg). According to the mass fraction of fat and protein in milk, the duration of the period of open days and the number of inseminations, there were no signifi cant diff erences between the studied groups of animals. Thus, the infl uence of specifi c sires on individual productive indicators of daughters has been established.

Studies of the structure of the interaction of signs with the help of factor analysis is based on the idea of the complex nature of the phenomenon being studied, expressed in the interdependence of individual signs, determined by “internal” hidden causes, forming the specifics of a property, quality. We used the factor analysis method to study the producers’ assessments of the quality of the offspring and to test their bullsons for their own productivity of the Kalmyk and Hereford cattle breeds. The analysis included material from the work of pedigree reproducers and plants in the Kalmyk and Hereford breeds of the Rostov Region. The total number of animals included in the treatment was 96 manufacturing bulls and 272 sons bulls. As a result of the studies, the proposed breeding indices on one basis are quite suitable for the preliminary selection of bullcalves in commodity farms or in pedigree farmers for breeding beef cattle. In order to get a final assessment, we compiled new breeding indices, including two (live weight at 8 and 15 months, live weight at 15 months and average daily gain from 8 to 15 months), as well as three characteristics (live weight in 8, 15 months and average daily gain). These signs are objective, easy to account. According to the estimates obtained for individual bull-sons, it is possible by summing up the values of new factors to identify the bulls’ assessment of the quality of the offspring. Analysis of assessment materials is characterized by high reliability (P > 0.999).

In domestic theory of breeding line breeding takes the leading place, because it uses the valuable genetic material of the bull’s leaders. Numerous studies have continuously monitored the economically beneficial traits of animals of different lines, both within breeding herds and in the general breed population. The Brown Carpathian cattle of the combined direction of productivity were officially recognized as breed and, accordingly, had all components of the breed structure (local lines and families). It should be noted that this breed has disappeared taking into account the fact that there has been no active (breeding) population since 2011. The purpose of the study is the schematic location of the bulls of the Brown Carpathian breed lines in generations, as well as the characterization of line extensions indicating the production of mothers. The material of the study was the State Books of Breeding Animals of eight volumes (1948, 1968, 1972, 1975, 1978, 1983, 1987 and 1992). Catalogs of dairy breed bulls for 1985–1988 were also used to evaluate the bull’s lines and groups. Since 1972 (the time of the official recognition of the breed) and until now (in the form of genetic material that is concentrated in cryobanks) the Brown Carpathian breed has the following local lines and related groups: Pishty 10 KAZ-67, Malchyka 3 KAZ-145, Shoni 6 KAZ-81, Fitsko 33 KAZ-107, Yury 32–Iuvelira 273, Kaplara 43 KAZ-9, Sokola 553 KAZ-182, Siroho 1759 KAZ-70, Bondi 101 KAZ-25 and Muki 100 KAZ-22 and Valsa 1205 KAZ-171. The total number of bulls under study is 535 heads, including the 1st generation – 109 heads, the II generation – 111 goals, III generation – 126 goals, IV generation – 99 goals, V generation – 65 goals, VI generation – 24 goals. and VII generation – 1 head. The investigated bulls were born during 1939… 1990 years. The related group of bull Bondi 101 KAZ-25 in the genealogical structure of the Brown Carpathian breed did not spread. The main reason was the small number of bulls. The bull was born in 1948 in the collective farm. Lenin of Mukachevo district of Zakarpattia region. Kappa’s 43 KAZ-9 local line. The ancestor of the line was born in 1944 and came from bull Shoni 2 and Montsii (8–300–4800–3.84). The live weight at the age of Kaplar 43 was 920 kg at the age of 11 with 82 points for the exterior. Local line of Malchyka 3 KAZ-145. The line's founder was born in 1948 and belonged to the collective farm. Dimitrov Mukachevo district of Zakarpattia region. Its origin is unknown. The Sokol’s 553 KAZ-182 local line. The founder of the line was born in 1949 and belonged to the collective farm "For a new life" of the Irshava district of Zakarpattia region. Its high live weight (5 years 840 kg) and body dimensions (height at the withers 145 cm, oblique torso length 180 cm, girth of the breast 220 and pestle 21 cm) ensured the animal’s mass. The related group of bull Muki 100 KAZ-22. The founder of the factory line was born in 1949 and had a brown suit and belonged to the collective farm. Chapayev. It was born of the Malyny 719, which received 4922 kg of milk for the fourth lactation and the bull Buki 220 of the Brown Swiss breed. The related group of bull Siroho 1759 ZCP-70. The founder of the bull Siryi 1759 was born in 1962 year. The live weight of 920 kg bull at the age of 5 years with 85,5 points for the exterior. The local line of Fitsko 33 KAZ-107. Bull Fitsko 33 has brown suit, was born in 1948, and belonged Zakarpattia Regional Agricultural Research Station. In the 12 years of its live weight was 840 kg. The local line of Pishty 10 KAZ-67. Pishty 10, the line's ancestor, was born in 1947 and was brown. He was born to a high-yielding cow Senesha 10, from which 2 lactations received 6240 kg milk of 3.7% fat, and bull Shandora 1. The Shoni 6 KAZ-81 local line is one of the leading in the Brown Carpathian breed. The ancestor of the line was born in 1949 from cow Fania 171, which for the 4th lactation yielded 4800 kg of milk with a fat content of 3.7% and the Fidelio bull of the Brown Swiss breed. The local line of the Yuri 32 KAZ-8-Yuvelira 273 KAZ-162 is the most numerous and branched in the Brown Carpathian breed. The ancestor of the lineage bull Yura 32 was born in 1943 from the cow of Cavia 517, from which for the 2nd lactation received 3014 kg with a fat content of 3.75%. Its live weight at 4 years was 850 kg. The related group of bull Valsa 1205 KAZ-171. The founder of Valsa 1205 was born in 1961 years. At 2 years of age, it had a live weight of 545 kg and a high exterior rating of 90.5 points. It came from Venetsia 564 (3–299–4416–3,6) and the Brown Swiss bull Iltis 7623. The genealogical structure of line breeding and related groups is presented covering the period of the birth of the bulls during 1939 ... 1990 and has 535 goals. During this time, local lines were tested and related groups were formed. The production lines of Pishta 10, Fitzko 33, Shoni 6 and Yury 32-Yuvelira 273, were the most numerous, and the number of bulls in each exceeded 70 goals. Less numerous (›6 goals) were the related groups of the Bondi 101 and Valsa 1205. Each group related to the ancestor has its twigs and branches.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

The most perspective genotype in our region is Red White-belted breed, which has high performance both under pure breeding and under crossing with other breeds. The results of complex evaluation of Red White-belted swine of the herd bred in SE "RF Zoryane" breeding farm are presented. It was revealed that animals of the farm comply with elite class and the first class. The main breeding boars used at the farm belong to such genealogical lines: Deviz, Division, Dantist, Debut, and Dobryak. In the structure of the herd, the most numerous was Dobryak line, which part was 58.8%, Division, Debut, Devis lines – 11.8% per line, Dantist line – 5.8%. The herd sows belong to 7 families: Drabowka, Dekada, Dyktsiya, Doina, Dylema, Delta, Dogma. Average prolificacy of the sows was 10.0 piglets. Litter weight at 60 days’ age was 181.0 kg, and live weight of piglet – 19.0 kg. The performance of sows as prolificacy increased by 0.6 head on average. The complex appraisal index for the herd was 104.1 points. The average daily gain of the replacement pigs was 570 g. The highest daily gain was from five to six months – 611.2 g, and the figure of compactness index characterized a certain elongation of animals, increasing meat traits. Further work with Red White-belted breed aims at preserving and expanding the breeding base and genealogical structure, as well as increasing the reproductive, fattening and meat traits.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

Whole Wheat

An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.
