Taking Some of the Guesswork Out of Winter Feed Challenges

This column usually focuses on research projects funded by the Beef Cattle Research Council (BCRC) through the Canadian Beef Cattle Checkoff that producers pay when they market cattle. But most individual research projects are like pieces of a jigsaw puzzle. Some of them may look interesting on their own, but they’re almost always a lot more informative when they’re put together with the other pieces of the puzzle to show the bigger picture.

That’s what extension (or “knowledge and technology transfer”) is about – turning science into cost-effective, useful solutions for producers. Historically, provincial agriculture departments were major players in extension, but many have pulled back from extension and redirected their staff towards government program delivery instead.

Private industry has partly filled this gap, but many producers remain skeptical about whether a sales rep’s advice is unbiased. As well, some production practices like grazing management and low-cost winter-feeding strategies aren’t “for sale.” There’s no profit motive for anyone but the adoptee, so there’s no clear driver for private industry to encourage their adoption.

Video: Season 6, Episode 6: The Science Behind Sudden Sow Deaths

Recent necropsies have revealed new insights into unexplained sow deaths, helping producers better understand the causes behind these losses. A recent study led by Laura Solis, a graduate student at Iowa State University, examined why these deaths occur, many around farrowing. In some cases, animals were sent to the lab for further analysis, as discussed by Dr. Marcelo Almeida, assistant professor in the College of Veterinary Medicine at Iowa State University. The episode also features Dr. Chris Rademacher, clinical professor and swine extension veterinarian as well as associate director of the Iowa Pork Industry Center, who asks questions of what seasonal factors there were and management strategies that can influence herd health outcomes.
