Orikhivskyi T. Productive features of animals of different production types of Simmental breed in the conditions of Prykarpattia

The thesis theoretically substantiates and proves the expediency of a comprehensive study of economically useful traits, their intergroup variability and population-genetic parameters in cows of different production types of Simmental breed in the conditions of Prykarpattia. It was found the degree of influence of individual factors on economically useful traits of animals and the relative variability of milk yield with morphological and biochemical parameters of blood and indices of stability of lactation calculated in different ways. It was found that the animals of the studied production types of Simmental breed in the breeding period exceeded the standard of breed. Analysis of the economic efficiency of breeding cows of different production types of Simmental breed showsthat it is more profitable to grow dairy and dairy-meat production types to increase milk production, and for meat production – meat-dairy animals.
