THE EFFECT OF MYCOTOXIN ADSORBENTS ON SOME SELECTED PARAMETERS OF BOAR SEMEN

Abstract

The studies were carried out at the State Enterprise for Pig Selection and
Hybridization "Moldsungibrid" (Republic of Moldova), from 18.03.2014 till
06.08.2014, using boars of Landrace, Yorkshire, Duroc and Pietrain breeds in order
to understand the impact of the enterosorbent "Primix-Alfasorb" on breeding boars,
semen production. During the first period of the experiment the adsorbent was not
added to the boars’ diet; during the second period of the experiment (60 days) the
basic compound feed (BF) was supplemented with the preparation "Primix-
Alfasorb" at the level of 300 g/t; during the final (third) period (40 days) the
animals were again fed to basic feed. It was observed that, when the breeding boars
were fed on compound feed supplemented with the additive «Primix-Alfasorb» at
the level of 300g/t, the ejaculate volume increased, namely: during the second
period of the experiment – in the boars of Landrace breed (p <0.05), and during
the third period – in the boars of Pietrain breed (p <0.1). The total number of
spermatozoa in the ejaculate was 139,54 milliard in Duroc boars, and up to 201,39
milliard in the boars of Pietrain breed. During the third period of the experiment,
this index was high in the boars of all the breeds. As to the concentration of the
spermatozoa, it was higher in Yorkshire boars by 13.52, 14.14 and 0.58%.
