FEEDING AND MEAT QUALITY YOUNG PIGS OF DIFFERENT INTERBREED DIFFERENTIATION ACCORDING TO THE TYLER INDEX AND ECONOMIC EFFICIENCY OF THEIR USE

Abstract

The article presents the results of the study of the fattening and meat qualities of young pigs of the universal direction of productivity, taking into account their interbreed differentiation according to the Tyler index, and also calculates the economic efficiency of the research results. The young pigs of the controlled population exceeded the minimum requirements of the elite class by 6.13% by the age of reaching the live weight of 100 kg, by 32.25% in the thickness of lard at the level of 6-7 thoracic vertebrae, and by 3.92% in the length of the chilled carcass. A significant difference between animals of different interbreed differentiation according to the Tyler index was founded by the average daily gain of live weight, the age of reaching a live weight of 100 kg, the thickness of lard at the level of 6-7 thoracic vertebrae, the length of the chilled carcass, the length of the bacon half of the chilled carcass. The maximum increase in additional production was obtained from young pigs of the 1st experimental group - +5.03%, and its value is +247.51 hryvnias or 8.59 US dollars/head. The theoretical basis for the research is the scientific works of domestic and foreign scientists
