Chernichko O. The formation of pig productive traits of different exterior types of body type in the ontogenesis process

The object - pigs of Large White breed, ontogenesis, productive traits and interior. The purpose is comparative studying of stretch and compact body types pigs growth both development from birth before productive use, is studying of pig reproductive ability at the breeding with boars of similar body types and establishment of contrasting body type pig-breeding zootechnik and economy efficiency. The methods are weighing, taking survey, hematological, biological and statistical analysis. The results - it is established, that formation productive traits on Large White breed of pigs in the ontogenesis process depend from exterior types; it is discovered sizeable hereditary possibility of pigs body types. Morphological structure of their carcass is greatly changing in time. The new introduction - modern genotype pigs productive forming main selective-genetic parameters digital quantities are calculated. The degree of introduction - is inculcation. The sphere of using is pig-breeding.
