The effect of genetic markers associated with boar taint on the basic boar sperm quality parameters
|Články v odborných časopisech
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’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. Statistically significant difference (p 0.05) were found among viability, velocity and sperm kinematic parameters of boar sperm and the genotypes of individual markers associated with boar taint.
