To increase the efficiency of pig farming, it is necessary to use modern, commercial, highly productive breeds, types and lines of pigs in industrial crossbreeding and hybridization systems. A comprehensive solution to this issue is the comprehensive study of the ethology of pig productivity. The prospect of the use of ethological tests in breeding is confirmed by the practice of work of foreign pig breeding companies, and therefore the study of intragroup hierarchical organization is one of the most important issues in the formation of pig behavior. In groups of pigs, a linear dominant hierarchy is usually formed, which is the most important regulatory system in animals.
On the basis of the above, the purpose of the research was to study the influence of social rank on the own productivity of repair pigs of Large white breed, Pietren breeds, Ukrainian meat, intra-breed Durok breed type Ukrainian breeding «Stepnoy» and breed combination ♀LW ×♂L in the conditions APC Agro-firm «Mig-Service-Agro» of Mykolaiv and LLC «Tavrian pigs» of Kherson regions, as well as their aggressiveness index under condition of joint cultivation of the mentioned breeds and breed combinations.
Studies have shown that in order to reduce the level of aggression, animals should be kept and raised accordingly breeds and breeds, as increased levels of aggression adversely affect the health and productivity of pigs. Our data indicate that pigs of large white breed are more aggressive.
Based on the results obtained, it is established that the motor activity index is dominated by high-grade repair pigs, where their index index varies in the breed range from 0.36 to 0.42 compared to its low counterparts (0.27-0.33).
The results of the evaluation of repair pigs on their own performance strongly show that the index of breeding value of the repair uterine stock of high social rank is significantly higher and varies by breed within 27.06-34.54 (p <0.001), and animals of low social the position in the group is probably inferior to this indicator, which, within the rocks, ranges from 22.95 to 29.63.
