Characterizing body temperature and activity changes at the onset of estrus in replacement gilts

The study objective was to characterize body temperature and activity changes in replacement gilts at the onset of estrus in order to provide initial data to develop a remote estrus detection system for commercial swine operations.

Abstract

Using first and second parity number born alive information to estimate later reproductive performance in sows

Early parity number born alive classification effectively predicts later parity performance. Sows classified as high in both parity one and in parity two had larger litters in later parities.

Abstract

Optimization of post-cervical artificial insemination in gilts: Effect of cervical relaxation procedures and catheter type

Post-cervical (pC) artificial insemination (AI) has been successfully developed for application in multiparous sows, although it has proved problematic in gilts. This study analyzes the use of pC-AI in gilts by two experiments.

Abstract

Effect of Pseudomonas aeruginosa on sperm capacitation and protein phosphorylation of boar spermatozoa

The present study provides novel data regarding the effects of bacterial contamination on boar sperm, suggesting that the presence of P aeruginosa affects the fertilizing ability of boar sperm by altering its ability to accomplish IVC.

Abstract

The effects of male and female immunocastration on meat quality of pigs intended for dry-cured ham

It can be concluded that immunocastration could be interesting in pigs intended for dry-cured ham elaboration because in males improved the feed conversion ratio with no penalization of carcass or meat quality.
