DOI: 10.1016/j.theriogenology.2020.03.020
Abstract: Sub-fertility is a major problem in crossbred bulls. Identification of subtle differences in the quality of cryopreserved spermatozoa among bulls belonging to different fertility rankings would help determine the latent fertility of semen before their… read more here.

DOI: 10.1093/biolre/ioac031
Abstract: Abstract Breeding soundness examinations for bulls rely heavily on the subjective, visual assessment of sperm motility and morphology. Although these criteria have the potential to identify infertile males, they cannot be used to guarantee fertility… read more here.
