Transportation stress, … Continue reading Artificial intelligence helps mitigate poultry heat stress
Photo by Rachel Vine on Pexels.com Laying hens are at risk of bone fractures due to biological changes linked with egg production. A novel method developed by The Roslin Institute in the U.K. enables poultry breeders to consider bone density in laying hen selection, which would allow greater bird health and welfare. Strong bones offer … Continue reading Novel imaging method to assess bone strength in hens
Pictured are broiler chicks in floor pens prepared with fresh (left) and reused (right) poultry litter. (Photo by Adelumola Oladeinde) In broiler chicken houses, the litter that the birds are reared on is a unique ecosystem that can make or break a flock. Litter management can be a much debated question, but a new study … Continue reading Reused litter may aid poultry health
Photo: Oregon State University. Specific probiotic combinations "significantly boosted" oyster larvae survival rates with only a one-time application, according to Oregon State University researchers. In a recent study, the researchers found that the probiotics also boosted larval growth, metamorphosis and settlement, meaning that in addition to more oysters surviving past the larvae stage, they also … Continue reading Probiotic combo ‘drastically’ improves oyster larvae survival

Photo: University of Illinois Dairy cattle are especially prone to reproductive health issues around calving, which affects fertility and conception rates in the next cycle, and a new University of Illinois study is showing that rumen-protected lysine may improve uterine health if fed during the transition period. “Right after calving, the uterus is undergoing a … Continue reading Lysine linked to reproductive health in dairy cows
Photo by Pamoni Photograph on Pexels.com Prescribed burning has been a pasture management practice in the Great Plains to help regenerate pastures in which an entire pasture is burned on a three-year rotation. But are there other practices that could have similar results and save cattle producers money? Ongoing Oklahoma State University research shows that … Continue reading Pastures: To burn (a patch) or not to burn (the whole thing)?
