Factors for improving reproductive performance of sows and herd productivity in commercial breeding herds

We review critical factors associated with reproductive performance of female breeding pigs, their lifetime performance and herd productivity in commercial herds. The factors include both sow-level and herd-level factors.

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.

Litter-of-origin trait effects on gilt development

Colostrum consumption, birth weights, preweaning growth rate, number weaned, and parity are associated with gilt development traits during later life.
