The influence of sexual use of the pigs males on their spermoproductions

Abstract

The pigs rearing depends of the level of hold selection work and of the reproduction as wile it depends of the artificial insemination. The efficiency of artificial insemination depends of the reproductions’ quality. The large number of the boars which have to be used in the reproduction process do not correspond to the enquirements because their low sperm quality. One of the most important cause of the boars is their wrong rearing, their late testing. The aim of the experiments was to elaborate the optimal methods of growing using, and effective methods of boars testing grown for the reproduction of the Moldovenesc meat type breed. The held experiments allow to develop the growing technology and boars using in industrial farm what include: the young boars males selection at the age of 3 month, the free feeding, their maintenance, in the groups by 4 – 6 piglets until six month age, and beginning with five month age the young boars males are trained for the sperm collecting.
