Dam Parity May Impact Pigs' Immunity Levels
Preliminary results of research at the University of Nebraska suggest that health status, as indicated by circulating immunoglobulin concentrations in baby pigs...
Don't Mix Sows 10-14 Days after Breeding
As pork producers take up the challenge to house gestating sows in groups vs. individual stalls...
Test Tube Pigs are Now a Reality
The ability to produce pig embryos in vitro (in the laboratory environment) has been mastered at Mississippi State University...
Management Tools Help Improve Reproductive Efficiencies
This study provides “proof-of-principle” that use of a purpose-built boar exposure area (BEAR) to induce a natural first heat in “select” gilts, and the use of low-dose exogenous gonadotropins to induce first heat in non-cyclic “opportunity” gilts,...
‘Skip-a-Heat’ Plan Helps Avoid Second-Parity Slump
Breeding Parity 1 sows at their second postweaning estrus has been shown to increase the number of live embryos detected at Day 30 of gestation. This increase in embryo viability may negate the effects of the second-parity dip in reproductive performance...
Management Effects on Group Sow Housing
Canadian researchers have learned that the productivity in electronic sow feeding (ESF) systems is comparable to sows housed in stalls, provided proper management practices are followed...
Structural Soundness in Commercial Gilts Studied
The objective of this study was to estimate leg soundness and body conformation trait variance using 1,449 gilts in a commercial sow unit. The gilts were from two commercial lines...
The Sow Stall Debate Continues
This Quarterly Benchmarking review offers some clues on how gestating sows performed in four different housing systems. Additionally, this fourth article...
Feeding Them Right
The sow herd is the engine that drives a pork production system. When things do not go well in the sow herd, the consequences ripple, and sometimes crash,...
Health Problems That Affect Fertility
Breeding-herd efficiency requires good fertility. Expected performance in the United States is to have conception rates of 92-94% and farrowing rates...
