“…Спеціалізовані українські чорно-ряба, червоно-ряба, червона та бура молочні породи великої рогатої худоби молочного напряму продуктивності створено за вказаними вище принципами і структуровані за типами, лініями і родинами [5-8, 10, 12, 13, 17]. Генетичний потенціал молочної продуктивності є досить високим, а його реалізація у кращих племінних стадах за надоєм перевищує 10 т [20].…”

The research was carried out on domestic breeds of dairy cattle, namely the Ukrainian black-and-white dairy cattle with a total breeding stock population of 100778 and the Ukrainian red-and-white dairy cattle - 35270. The material was based on the structural formations (intrabreed types) - Southern (6528 heads in 12 herds), Central-eastern (49001 heads in 69 herds), Western (15746 heads in 19 herds), Polissya (27031 heads in 38 herds) and Sumy (2472 heads in 4 herds), they belong to the Ukrainian black-and-white dairy cattle, and the Central one (23822 heads in 41 herds), South-eastern (8431 heads in 16 herds), Prykarpattia (3017 heads in 3 herds) to the Ukrainian red-and-white dairy cattle. It is established that intergroup differentiation was observed on quantitative and qualitative indicators. Thus, the highest average hopes were observed in cows of the Central-eastern (7640 kg) and the South-eastern (7184 kg) types. In other structural formations, milk productivity ranged from 6012 kg to 6951 kg. Live weight of cows of the Western type is 553 kg, with low amplitude of other types (560 kg… 579 kg). The range of the main components of milk in the studied intrabreed types in terms of fat and protein content is 3,67%… 4,04% and 3,13%… 3,27%, respectively. In each intrabreed type there is a selection nucleus for selection of the best cows and obtaining valuable offspring from them, the analysis of which showed a tendency to increase the milk yield of lactating cows by an average of 457 kg and their live weight - by 11 kg. Also, the main components of milk have a fluctuating level, which does not depend on lactation and intrabreed types, which in turn may indicate inadequate selection for them. According to the analysis of the distribution of cows by calving, a high share of first-borns in the structure of types was noted, which ranges from 27,3% in the Western to 41,2% in the South-eastern types. Key words: breed, intra-breed type, milk productivity, live weight, breeding stock population, herd structure, age of first calving.

Zonal genotypes have already been created using imported breeds to increase the number of meat cattle in Ukraine, but not enough studies related to the specific features of breeding and feeding imported genotypes in the Steppe zone of Ukraine have been conducted, which is relevant. The purpose of the study is to examine the productive and slaughter indicators of bulls of imported meat breeds of various ecological and genetic origins in the climatic conditions of the steppe zone of Ukraine. Zootechnical, morphometric, biometric, and statistical methods were used in the research. The results of an analysis of the meat productivity of bulls of imported meat breeds of Maine-Anjou, Chianina, and Santa Gertrudis in the age aspect in the conditions of the steppe of the Dnieper region of Ukraine are presented. It was identified that when slaughtering experimental animals at the age of 18 months, the mass of paired carcasses of Maine-Anjou and Chianina was quite high and amounted to 324.2 and 311.3 kg, respectively, and the Santa Gertrudis – 233.3 kg, which is 1.39 and 1.33 times less than the young animals of Maine-Anjou and Chianina, respectively. It is proved that to use livestock more efficiently and obtain high-quality beef to improve the supply of meat to the population, it is advisable to grow them up to 18-24 months of age. Maine-Anjou animals dominate in terms of growth energy, age of reaching live weight during key growing periods, and feed conversion. In addition, due to the pronounced massiveness and habit of the body, have a larger carcass mass, the amount of internal fat, offal, as a result of which, the slaughter yield is higher. Based on the conducted studies, the possibility of effective breeding of Maine-Anjou bulls up to 12 months of age is proved, since during this period they reach a live weight of 400 kg and are characterised by the high production rate of lean beef, and for Chianina breed – up to 18 months of age and bigger weight conditions
