Description
The aim of this study was to find the relationship between fertility (as 90‐day non‐return rates) and DNA fragmentation assessed by two techniques [sperm chromatin structure assay (SCSA) and Sperm–Bos–Halomax (SBH)]. Furthermore, other quality parameters were achieved (motility, morphological abnormalities, cytoplasmic droplets, viability, capacitation and acrosomal and mitochondrial status) and their correlations with fertility were analysed. Bulls were divided into three fertility groups: high [non‐return rate (NRR) ≥ 80], medium (80 < NRR ≥ 70) and low (70 < NRR > 40). The results of this study indicate that there is a good correlation between fertility and different parameters of sperm quality (SBH and SCSA parameters, % of spermatozoa with head, neck and total abnormalities, and % of spermatozoa with proximal cytoplasmic droplets) and differences between fertility groups were observed in …
