INFLUENCE OF DAILY COLLECTION ON EJACULATE QUALITY FROM PIETRAIN BOARS
Keywords:
boars, ejaculates, semen qualityAbstract
The purpose of our research was to establish the influence of daily collection the
quality and quantity of semen form Pietrain boars. They were kept and fed in
optimum conditions between 10th and 14th December 2007. The values of ejaculate
parameters are mainly influenced by the genetic heritage of each animal and its
particular physiological traits and not by age. Among ejaculate parameters
concentration is the most constant for a period of time after which it decreases
suddenly. Therefore it can be viewed as a reliable ground for the decision to collect
semen from the same boar the following day. Volume and concentration decrease
dramatically from the third day, while motility is more constant. The number of
doses per ejaculate is much lower from the third day onwards. Together with semen
quality this indicates that daily collections in Pietrain boars can be conducted but
no more than for 2 consecutive days without negative economic effects.
