BLUP INDEX: CRITERIA OF SELECTION OF HIGH PRODUCTIVITY SOWS AND ECONOMIC EVALUATION OF THEIR USE

Abstract

The paper presents the results of the study of indicators of the own productivity of repair pigs and reproductive qualities of sows of different intrabreed differentiation according to the BLUP index, as well as to determine the economic efficiency of the use and selection criteria of highly productive animals.

It was established that repair pigs of large white breed by the age of reaching a live weight of 100 kg (days) and a fat thickness at the level of 6-7 thoracic vertebrae (mm) belong to the elite class. Sows of I experimental group are characterized by the maximum indicators of multifertility, milk yield, number of piglets at the time of weaning and weight of the nest at the time of weaning (BLUP index = 106.35-128.76 points). The index of M. D. Berezovsky in the animals of the specified group, is equal to 40.90±0.511 points. The number of reliable correlations between the indicators of the reproductive qualities of the tested sows and the BLUP index (maternal line) is 83.33%; the relationship between the BLUP index (maternal line) and signs of own productivity is weak and unreliable (r= –0.039 - +0.009). The use of sows of high breeding value (I experimental group) provides additional production at the level of +7.70 %, and its cost is +300.53 UAN or +7.60 dollars per head / farrowing. The criterion for selecting highly productive animals of the controlled population is the value of the BLUP index at the level of 106.35-128.76 points.
