New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…

Animal scientists in Brazil have found that a small dose of the feed additive ractopamine can boost pork production without changing how pork looks or tastes.In the latest issue of the Journal of Animal Science, researchers report that a 5 mg/kg dose of ractopamine increased muscle mass and feed efficiency, and had no noticeable effect on pork marbling, fat content, toughness or color. The researchers came to this conclusion by testing pork from 340 pigs raised under commercial conditions….
