The Impact

A model beef cattle breeding scheme consisting of a breeding unit and a commercial unit was used to evaluate the impact on genetic gain and profitability of incorporating feed intake measurements as an additional selection criterion in breeding programmes. Costs incurred by the breeding unit were compared with returns generated in the commercial unit, with bulls from the breeding unit being used as sires in the commercial unit. Two different market objectives were considered — a grass-fed product for the Australian domestic market, and a grain-fed product for the Japanese market. Breeding units utilising either artificial insemination or natural service were also considered. A base scenario was modelled incorporating a range of criteria available to Australian cattle breeders. A second scenario incorporated selection of sires for the breeding unit using a 2-stage selection process, with a proportion of bulls selected after weaning for measurement of (residual) feed intake. Measurement of feed intake of bulls improved accuracy of breeding unit sire selection by 14–50% over the equivalent base scenario, and genetic gain in the breeding objective was improved for all scenarios, with gains ranging from 8 to 38% over the base scenario. After accounting for the cost of measuring feed intake ($150–450), additional profit was generated from inclusion of feed intake measurement on a proportion of bulls for all breeding schemes considered. Profit was generally maximised where 10–20% of bulls were selected at weaning for measurement of intake, with improvement in profit ranging from 9 to 33% when optimal numbers of bulls were selected for intake measurement.

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.

Рассмотрены состояние и перспективы развития мясного скотоводства в Российской Федерации. Проведен мониторинг численности поголовья, породного состава и продуктивности мясного крупного рогатого скота во всех категориях хозяйств, изучены масштабы и объемы бонитировки скота за 20102018 годы. По данным Минсельхоза России, в 2018 году поголовье крупного рогатого скота в стране составило более 18 млн голов, в том числе численность животных специализированных мясных пород во всех категориях хозяйств достигла 2,26 млн голов. Комплексная оценка 711,16 тыс. голов, или 34,1 от общей численности мясного скота, в том числе 389,8 тыс. коров, принадлежащих к 15 породам и типам, разводимым в 57 регионах Российской Федерации показала, что наибольшее подконтрольное поголовье имеют абердин ангусская порода (417545 гол.), калмыцкая (137262 гол.), герефордская (87278 гол.) и казахская белоголовая породы (52563 гол.). Все подконтрольное поголовье животных является чистопородным и IV поколения, в том числе 99,7 быков-производителей и 99,3 коров. Анализ живой массы пробонитированного поголовья выявил тенденцию к ее повышению у коров всех возрастов в среднем на 54 кг, быков производителей на 39 кг, или на 16,7 и 5,2 за последние 9 лет, соответственно. Живая масса коров по итогам 2018 года в среднем составила 546 кг, быков-производителей 791 кг. По состоянию на 1.01.2019 года, племенная база мясного скотоводства страны представлена 270 племенными стадами, в том числе 46 племенными заводами и 224 племенными репродукторами. В 2018 году в различные категории хозяйств из племенных предприятий было продано 35517 голов племенного молодняка, в том числе 6388 ремонтных бычка с классами элита и элита-рекорд (85,3). В 2018 году было продано племенного молодняка в расчете на 100 коров галловейской породы 33,0 головы, казахской белоголовой 29,1 герефордской 28,0 калмыцкой 22,2 лимузинской 15,5 абердин ангусской 8,8 русской комолой 8,2 и симментальской мясной 4,7 голов. На основании мониторинга состояния мясного скотоводства страны за 20102018 годы были намечены перспективы дальнейшего развития.The article considers the state and prospects of development of beef cattle breeding in the Russian Federation. The number of livestock, breed composition and productivity of beef cattle in all categories of farms was monitored, the scale and volumes of bonding of cattle for the studied 9-year period (20102018) were studied. According to the Ministry of Agriculture of Russia, in 2018 the number of cattle in the country amounted to more than 18 million heads, including the number of cattle of specialized meat breeds in all categories of farms reached 2.26 million heads. A comprehensive assessment of the number of livestock in the amount of 711.16 thousand animals or 34.1 of the total number of beef cattle, including: cows 389.8 thousand heads belonging to 15 breeds and types bred in 57 regions of the Russian Federation, showed that the largest controlled livestock are: Aberdeen Angus breed 417545 animals, Kalmyk 1372726 animals, Hereford 87278 animals and Kazakh white-headed breed 52563 animals. Almost all of the controlled livestock of animals is purebred and IV generation, including: respectively 99.7 of bulls producers and 99.3 of cows. The analysis of live mass of a livestock revealed a tendency to its increase at cows of all age on average on 54 kg, bulls on 39 kgor for 16.7 and 5.2 for the last 9 years respectively. The live mass of cows following the results of 2018 averaged 546 kg, bulls 791 kg. As of January 1, 2019, the breeding base of beef cattle breeding in the country is represented by 270 breeding herds, including: 46 breeding plants and 224 breeding reproducers. In 2018, 35,517 heads of pedigree young animals were sold to various categories of farms from pedigree enterprises, including 6,388 repair bulls with elite classes and an elite record record for appraisal (85.3). An analysis of the sales volume of pedigree young animals in the context of farmed meat breeds showed that in 2018 pedigree young animals per 100 cows were sold in the country: Galloveian breed 33.0 goals, Kazakh white-headed 29.1 goals, Hereford 28, 0 goals., Kalmyk 22.2 goals., Limousin 15.5 goals., Aberdeen Angus 8.8 goals, Russian kolola 8.2 and Simmental meat 4.7 goals. Based on the monitoring of the state of beef cattle breeding in the country for the study period (20102018), prospects for further development were outlined.
