Read about the first research indicating that boots, coveralls, and gloves can spread influenza and novel genetic markers to protect against shedding salmonella, plus PRRS vaccines and cleanup strategies. Researchers learn that inadequate feed intake hurts sow performance, genetic research offers clues to PRRS resistance, ponder how heat stress affects expression of estrus and learn how to screen boar semen for cryopreservation. Read about how the captive bolt can be an effective single-step euthanasia method and how the impact of alley width impacts sow performance in free-access stall systems. Get more details about how cortisol levels are an indicator of lame sows, and a see how a consumer survey outlines pork perception issues. Researchers suggest it is possible to quantify sow body condition and also lay out details about housing and dietary effects on sow performance. Learn about a strategy utilizing pen sampling to improve market weight distribution, and explore the value of natural vitamin E for sows. Research shows that feeder type impacts carcass and production traits and researchers strive to get to the root of fallback pigs.
