Trait Interactions Offer Clues to Sow Lifetime Performance
A 10-year snapshot of PigChamp data shows the average culling frequency of breeding females in U.S. commercial herds is 45%, while mortality rates stand at nearly 8%....
Sows' Sensitivity to Heat Stress Studied
Seasonal infertility is prevalent in sows during summer months and is problematic for producers striving to maximize reproductive efficiency...
Track Age, Weight to Boost Sow Lifetime Performance
Gilt development programs are often complex and conflicting because the research does not conclusively reveal the impact of gilt growth on lifetime sow productivity....
Health Rules for Replacement Gilts
The problem with gilts is that they have to be gilts before they can be sows....
What is Net Present Value?
Net Present Value (NPV) analysis is the process of taking a current investment (in this case the replacement gilt), and projecting the future net income...
Sow Housing Affects Offsprings' Growth, Puberty
Fetal programming is a phenomenon by which a significant or constant stimulus in the sow's uterus establishes a permanent response in the fetus that impacts physiologic function later in life. It has been reported that pregnancy rate was 15% higher...
Fetal Imprinting May Affect Pigs' Lifetime Performance
If the fetus is stressed during development, the pig may be programmed for a lifetime of unfavorable consequences, explains Lee Johnston...
Dam Parity Influences Litter Performance, Pig Health
University of Nebraska researchers have confirmed earlier work indicating that sow parity affects the health status of her progeny....
Marker-Assisted Selection Could Boost Sow Performance
The length of a sow's productive life (SPL) in a breeding herd is impacted by reproductive performance, locomotion and structural soundness....
Wireless Pregnancy Detector Introduced
Virtual scan ultrasound system for sows is lightweight and cordless. ECM has developed a new ultrasound device to meet the specific needs of pork producers...
