Relationship between in vitro sperm functional assessments, seminal plasma composition and 1 field fertility following AI with either non-sorted or sex-sorted bull semen

This study suggests that different in vitro markers of fertility are required to predict the fertility of non-sorted (NS) and sex-sorts (SS) semen.

The micro-RNA content of unsorted cryopreserved bovine sperm and its relation to the fertility of sperm after sex-sorting

A set of miRNAs detected in conventionally produced semen batches were linked to the fertilizing potential of bovine sperm after sex-sorting and should be further evaluated as potential biomarkers of a sire’s suitability for the production ofsex-sorted sperm.

SIRE CONTRIBUTION TO PREGNANCY ESTABLISHMENT AND MAINTENANCE IN BEEF COWS

The most common measurements of herd fertility and the importance of using calving rate in order to get the most accurate sire fertility evaluation are addressed, as well as the role of sire in pivotal periods of gestation and its 4 contribution to pregnancy loss.

Review: Genomics of bull fertility.

Considering the rapidly increasing rate of adoption of high-throughput single nucleotide polymorphism genotyping in both the US dairy and beef industries, genomic selection should be the most effective of all currently available approaches to improve male fertility.

Effect of seminal plasma from high- and low-fertility bulls on cauda epididymal sperm function.

In conclusion, SP affects the physiological function of CES but there is no difference between SP from high- or low-fertility bulls.

Fertility differences between groups of sires relative to the stage of oestrus at the time of insemination

The average interval from insemination to ovulation and fertilization is related to the stage of oestrus at inseminations, and this interval was the major factor contributing to the fertility differences between the groups of sires included in this experiment.

Artificial Insemination in Cattle Breeding in Kenya

Fertilization Rates and Embryonic Death Rates in Cows Bred to Bulls of Different Levels of Fertility

It appears that approximately 40% of all potential young in dairy cattle are lost by 60-90 days after breeding, as percentages of the potential young producible by a female group.

Detection of differences in fertility.

The relationship between the number of spermatozoa inseminated and the reproductive efficiency of individual dairy bulls.

Multiphasic analysis of reproductive efficiency revealed bull differences in estimated conception and calving rates that implies that the ranking of the bulls for nonreturn rate 56 d after AI changes with the number of spermatozoa inseminated.

SIGNIFICANCE OF SEMEN CULTURES FOR MEN WITH QUESTIONABLE SEMEN QUALITY

A high incidence of positive cultures in this study was probably due to stringent patient selection and the comparative culturing procedure, and the presence of pathogens may indicate the need for treatment especially prior to IVF and IUI.
