| Popis: | 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. |
