Change in electrical resistance in the vagina has the potential to accurately predict ovulation timing, but more work is required.

The results reveal better sperm quality for untreated boars than for PGF2α-treated boars, which might indicate that the underlying fertility of boars necessitating treatment is inferior compared to boars that can be collected without further treatment.

The semen of older boars contained a higher abundance of harmful bacteria, which contributes to the observed reduction in semen anti-oxidant capacity and overall semen quality in this group.

Group housing gestating sows 2 days after breeding compromised litter size; however, mixing gilts on days 1 to 4 after breeding did not impair reproductive performance.

This work aims to summarise the methods utilised in farms and research laboratories to evaluate sperm quality in pigs.

Spermine and spermidine alleviate oxidative stress via the antioxidant capacity, thereby improving the efficacy of boar semen preservation.

The study assessed whether vaccines administered to the uterus at breeding can lead to sufficient colostral antibodies to protect suckling piglets against PEDV.

Post-cervical artificial insemination doses took less time than cervical doses to reach the desired temperature, but sperm quality was similar for CAI- and PCAI-doses during storage.

The objective of this study was to develop alternatives to hormonal treatments to synchronize oestrus of gilts.

The future design of AI strategies and catheters should take into consideration the morphological variations of the cervix lumen, which will depend on age and parity of the females.

The seminal plasma from the sperm-rich fraction is important for the maintenance of adequate structural and functional characteristics of extended liquid boar semen.

The use of the deep cervical AI technique provides a new AI method as an alternative to cervical insemination and post-cervical artificial insemination for pigs.

Mounting evidence indicates that light irradiation of mammalian spermatozoa (and of other animal species) increases their motility, capacitation and fertilizing ability, without causing any damage on the DNA.

Boars sperm membrane proteins may explain differences in semen cryopreservation success, serving as freezability markers.

Sperm motility, morphology and three seminal plasma proteins were positively associated with heterospermic boar fertility.

The objective of the research was to conduct semen parameter and conception rate analyses on the basis of growth rate and meat content.
