Influence of Terminal Boar Genetic Type on Conception Rate

Abstract

The existence of variability between boar genetic types on sows fecundity (measured by the percentage of fertile insemination or percentage of return after insemination) was observed in some studies but is insufficiently experienced and explained. The aim of this paper is to underline the existence of influence of terminal boar genetic type on sows conception rate. In this way, were studied three lines of boars, which were mated with females of the same genetic type, as a scheme that prevents, if possible, the maternal influence. Research has revealed the existence of differences between genetic types of boars, but they are not statistically significant. Therefore, these observed differences can be attributed to other factors, particularly technological nature, which does not affect equality of opportunity for installation of pregnancy.
