The effect of genetic markers associated with boar taint on the basic boar sperm quality parameters

Popis výsledku v původním jazyce

Boar taint is mainly caused by androstenone (A) and skatole (S) which are stored in fat tissue and negatively affect meat quality. The objective of this study was to find out whether various genetic markers for possible reducing the occurrence of boar taint have an effect to the basic quality indicators of boar sperm of the Přeštice black-pied breed (PC). Native ejaculates were collected from 12 AI fertile boar&apos;s PC breed during 2 years. The following basic boar sperm quality parameters were evaluated: sperm volume, sperm concentration, total number spermatozoa per ejaculate, % morphologically of abnormal spermatozoa, sperm motility (velocity and sperm kinematic parameters), % of live spermatozoa and sperm viability during 96h of storage. Genetic markers that are associated for boar taint CYP2E1 genotype CC increases the level of S, TEAD3 genotype CC increases the level of A, HSD3B genotype GG decreases the amount of A, CYB5A genotype TT and GT decrease the level of A, FMO1 and FMO5 genotype GG increases the level of A were used for this study. Statistically significant difference (p &lt;0.05) was noted for CYP2E1 marker between TC and CC genotypes in sperm volume in the basic boar sperm quality parameters. No statistically significant differences (p&gt;0.05) were found among viability, velocity and sperm kinematic parameters of boar sperm and the genotypes of individual markers associated with boar taint. In conclusion, it can be said that according to the results obtained so far, the differences among genotypes for individual genetic markers associated with boar taint appear to be statistically inconclusive. It can therefore be concluded that breeding to reduce boar taint should not have a negative effect on the fertility of breeding boars.
