Description
| - The purpose of the study was to analyse frequency of aneuploidies of sex chromosomes and chromosome 6 by three-colour FISH in 47 young fertile bulls and to investigate the influence of aneuploidies and disturbed sperm chromatin integrity on non-return rates, the frequencies of abortions, perinatal mortality and stillbirths. Significant correlation was found between sex disomy, total aneuploidy (disomy of chromosomes 6, X, Y and XY sperm and diploidy) and stillbirths (r=0.390; P=0.013; and r=0.331; P=0.037), non-return rate and total aneuploidy (r=-0.310; P=0.036). Chromosome 6 disomy correlated with perinatal mortality (r=0.317; P=0.047). HDS correlated significantly with total aneuploidy (r=0.449; P=0.002). Our study indicated that aneuploidy frequencies in young fertile bull sperm are relatively low. Nevertheless, there exists a variability in aneuploidy frequencies amongst bulls, which appears to be able to have an influence on the fertility of these animals.
