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 andHybridization "Moldsungibrid" (Republic of Moldova), from 18.03.2014 till06.08.2014, using boars of Landrace, Yorkshire, Duroc and Pietrain breeds in orderto understand the impact of the enterosorbent "Primix-Alfasorb" on breeding boars,semen production. During the first period of the experiment the adsorbent was notadded to the boars’ diet; during the second period of the experiment (60 days) thebasic compound feed (BF) was supplemented with the preparation "Primix-Alfasorb" at the level of 300 g/t; during the final (third) period (40 days) theanimals were again fed to basic feed. It was observed that, when the breeding boarswere fed on compound feed supplemented with the additive «Primix-Alfasorb» atthe level of 300g/t, the ejaculate volume increased, namely: during the secondperiod of the experiment – in the boars of Landrace breed (p <0.05), and duringthe third period – in the boars of Pietrain breed (p <0.1). The total number ofspermatozoa in the ejaculate was 139,54 milliard in Duroc boars, and up to 201,39milliard 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 thespermatozoa, it was higher in Yorkshire boars by 13.52, 14.14 and 0.58%.
