Вопросы развития мясного скотоводства нельзя рассматривать в отрыве от всей инфраструктуры подотрасли. Селекционные достижения в видеживотных и стад с высоким генетическим потенциалом продуктивности являются только средствами производства, которые реализуются в производственных условиях — товарных хозяйствах и на откормочных предприятиях. В инфраструктуре подотрасли рассмотрены сферы производства как функционального назначения (основные и вспомогательные), так и по отраслевому признаку (межотраслевые и внутриотраслевые), дано краткое их описание и назначение.

Resumen
Beef is a source of animal protein in demand by the Indonesians. The development of cattle breeding in Indonesia needs to grow. One factor that causes the stagnation of cattle breeding is reproductive disorders. A reproductive disorder that local farmers in Indonesia often find is repeat breeding. This study aimed to know the Body Condition Score (BCS), Sodium (Na), and Chloride (Cl) between fertile and repeat-breeding cattle. This study used ten Simmental-PO cattle, and the research was conducted in Ngaglik Sub-District, Sleman City, Special Region of Yogyakarta Province. Cattle were divided

Indonesia has a number of cattle breeds that have certain advantages as meat-producing cattle with high adaptability to the local environment. Local beef cattle breeding has now been carried out by the government through technical implementation unit. Efforts to build local cattle breeding still need to be improved to be able to meet sustainably the demands of local cattle breeding stocks for the farmers. However, beef cattle breeding business is less attractive to investors because it is economically less profitable and requires a long maintenance time compared to the fattening business. This

Resumen
Abstract This article deals with transformations in beef cattle breeding practices in North America from 1950 to 2000, and the implication of these changes across the Western world. It was a period of profound adjustment for beef cattle breeders, involving battles over genetic defects, the importation of new breeds, changing standards in relation to husbandry, and the extension of quantitative genetic breeding practices. These innovations would be echoed across Europe in the production of beef cattle and would also interact with the way dairy cattle were bred. This article explains the upheava

Selection differentials and selection indices in retrospect were calculated to determine the relative emphasis placed on production and type traits through bull selection. Indices in retrospect including only production traits indicated that, for Holsteins, fat yield was the trait most heavily selected for between 1978 and 1987, followed by protein percent and then milk yield. Fat percent and protein yield had negative index weights throughout the nine year period. In Ayrshires, similar weights were observed except that milk yield index weights were negative throughout the nine year period. It

Resumen
Recent studies show polymorphisms in the leptin gene significantly impact milk production in dairy cattle. If the leptin gene were to have a similar impact on beef cattle, calf weaning weights would be expected to increase from the increased milk production in the cows. Since weaning weight is a key component of profitability in a cow-calf operation, leptin genotyping may prove to have an economic impact in breeding cattle. However, no research has been done to link the economic impact of increased milk production to breeding cattle. Using 595 observations from genotyped cows spanning 11 years

In the European Union (EU), the cattle sector is made up of meat and dairy farming. These sectors are closely interlinked, as a significant proportion of dairy cows are slaughtered for meat. In the mid-1990s, as market conditions changed in Latvia's agricultural sector, the development of specialised breeds of beef cattle began, so the aim of the research is to examine trends in the development of beef cattle breeding in Latvia. Dairy farming is still one of the largest agricultural sectors in Latvia, but between 2003 and 2023 the total number of specialised beef cattle herds in Latvia has dec

Correlations between economically useful parameters of Holstein cattle (Russian breeding) are considered. When selecting the first heifers by milk yield, it is possible to predict an increase in the absolute yield of fat and protein and an increase in the duration of the period from calving to fruitful insemination. The selection of cows by fat content simultaneously leads to an increase in protein levels in milk. Animal breeding by live weight is ineffective in farming conditions.

Meiotic recombination is one of the important phenomena contributing to gamete genome diversity. However, it is not well studied in livestock including cattle. The general objectives of this project were to perform genetic analyses of recombination and PRDM9 alleles and study their implications in dairy cattle breeding. The specific objectives were: 1. Analyze variation in recombination across individuals, breeds, and environments; 1.1.Construct individual-level recombination maps; 1.2.Compare recombination features between bulls held under different environmental conditions in US and Israeli;
