The main objective of this thesis was to develop a protocol to efficiently apply flow cytometric sex-sorting procedure on boar spermatozoa.

This is the first described relationship between reproductive failure and toxic compounds released from plastic bags.

Data suggest that the oviduct functions as a biological sensor that screens the spermatozoon, and then responds by modifying the oviductal environment.

Supplementing freezing media with 2 mm GSH greatly improves boar sperm cryopreservation technology, as it significantly improves the fertilizing ability of frozen-thawed spermatozoa.

These data suggest that concentrations of skatole and androstenone can be reduced through genetic selection without negatively affecting important male fertility traits in Danish Landrace pigs.

This study evaluated pre-freezing and post-thawing boar sperm quality in distinct portions of the ejaculates and identified protein bands potentially related to boar sperm tolerance to freezing.

Supplementing a basal diet with organic or inorganic selenium did not affect semen quantity or sperm quality in fresh ejaculates.

Boars need to be treated as individuals and fed accordingly. It is advisable to weigh the boars frequently to maintain the correct plane of nutrition.

In the present study, intrauterine deposition of sperm did allow maintenance of farrowing rate, but did not ameliorate the adverse effect of inseminating aged sperm on litter size.

Boars having normal (71.1 ± 1.2%; n = 10) or low (35.12 ± 3.9%; n = 10) sperm motility 24 h after collection were used, and semen was evaluated following storage in Beltsville Thawing Solution (BTS) for 24 h at 18°C. Sperm lipids were extracted and lipid peroxidation quantified.

Capacitation status as measured by CTC staining is a useful predictor of sperm fertility, equivalent to SPA. Moreover, original capacitation status exhibited better predictive ability for small litters than for large ones. Therefore, subfertile boars can be identified primarily by capacitation status

The present study was conducted to evaluate non-return rate (NR), farrowing rate (FR), and number of total pigs born/litter (TB) of weaned sows after intra-uterine insemination (IUI) using low numbers of frozen–thawed (FT) spermatozoa.

The present studies confirm an adverse effect of inseminating FT sperm on sperm quality and sow fertility but suggest that thawing FT sperm in 50% SP may partially alleviate these adverse effects.
