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...
Proper AI Techniques, Semen Handling
The first and overriding principle of artificial insemination (AI) in swine is if a sow is in standing heat, she can be bred; if she is not in standing...
Effective Heat Detection Methods Poster
Effective heat detection, accurate recording of estrous cycles, and subsequent, well-timed matings or inseminations are critical to achieving high reproductive...
