Abstract

The success of artificial breeding program depends largely on the reproductive performance of males. Male performance can vary with season and age impacting on quality and quantity of semen collected for artificial insemination purposes and therefore fertility of inseminated females. We examined...

AbstractFull Text

The off-breeding season for rams is a time-limiting factor for their use in scientific aims. This research was set upon two aims: (1) to acknowledge the differences of semen quality collected throughout the year, and (2) to investigate which of the two commonly used methods for semen collection (...

AbstractFull Text

The biological material was represented by 15 boars of Large White, Duroc and Landrace breed. Age of the boars was between 8 months and 31 months. Collecting frequency was reduced: one collecting followed by five days pause. At each collecting it was determined the volume of the ejaculation, the...
