Increasing feed intake during late gestation may improve sow and litter performance.

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.

Microbial abundances and community structures differed significantly between sows with different litter sizes and gestation stages.

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

Natural betaine fed to sows during lactation and postweaning show benefits on performance only during summer months.

Reproductive tract scoring methods as a tool for identify gilts with improved productivity as breeding herd females.

There is a lack of information about progesterone supplementation during early pregnancy regarding swine embryonic development. The objective was to evaluate the effects of progesterone/progestin supplementation from Day 6 of pregnancy on swine reproductive parameters.

L-proline supplementation during early-pregnancy improves litter size and birth weight in sows with negative energy balance.

A genome-wide association study was performed to identify quantitative trait loci for SLP-related traits. A total of five genome-wide suggestive significant single nucleotide polymorphisms were identified.

Arginine and other amino supplementation in gestating gilts improve farrowing and litter performance in low prolificity sows (≤14 total piglets born).

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.

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.

A high avulation rate results in an moderate increase in the number of vital embryos at day 35 of pregnancy, but compromises development in the surviving embryonic/placental units, suggesting that the future growth and survival of the embryos might be further compromised.

On the basis of the presented results, it should be noted that the use of oxytocin into insemination doses improves the farrowing rate and other parameters of the reproductive performance of sows.

Researchers from Wageningen University explain that a number of important characteristics of European pigs have Asian origins.

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