Efectul utilizării vierilor hibrizi în sporirea capacităţii de creştere şi dezvoltare a tineretului suin

Abstract

The present study has been aimed to evaluate the growth and development performances of young swines obtained by crossing Large White x Landrace sows with pure bred boars (Pietrain and Duroc), as well as with two-breed hybrid boars (Pietrain x Duroc) and three-breed boars (Large White x Landrace x Pietrain). A total of 150 young hybrids (75 gilts and 75 piglets) from 30 sows were included in the study. It was established that the progeny obtained by combining the Large White x Landrace (female parent) with Duroc and Pietrain x Duroc (male parents) achieved more relevant results as regards body mass accumulation and growth rate that is explained by the effect of the combining ability of maternal and paternal genotypes and by the degree of manifestation of heterosis phenomenon. In all growing periods male swines achieved higher body weights compared to the gilts. Weight differences become more evident beginning with the age of 120 days.
