Role of vitamin D in bovine TB investigated

Photo by Matthias Zomer on Pexels.com While bovine tuberculosis (bTB) has been "nearly eradicated" in the U.S., according to USDA's Animal & Plant Health Inspection Service, Europe continues to struggle with the disease, particularly in the U.K. and Ireland. Across Ireland, it is estimated that bTB-infected herds have a 30-40% chance of the disease recurring … Continue reading Role of vitamin D in bovine TB investigated

Project hopes to solve mastitis on organic dairy farms

In organic dairy production, producers are limited on disease prevention and treatment options. Organic dairies have fewer tools in their animal health toolbox due to organic program standards, but their cows are still faced with disease conditions. Bovine mastitis is one of the most common and costly diseases in the dairy industry, and a multi-state … Continue reading Project hopes to solve mastitis on organic dairy farms

Chasing dreams, chasing dollars: Organic grass-fed dairy sector sees growth

Holstein cows eating pasture grass at an organic grass-fed dairy farm. Photo: University of New Hampshire A "perfect storm" of issues has hit hard New England’s organic dairy farms (average herd size of about farms with 100 or fewer milking cows). For many years, organic dairies in New England and the Northeast U.S. remained viable … Continue reading Chasing dreams, chasing dollars: Organic grass-fed dairy sector sees growth

Lysine linked to reproductive health in dairy cows

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

Barnyard Roundup: Potential oilseeds; milk fat; fish feed

Brucellosis study targets cellular function

Photo: Washington State University While brucellosis in the U.S. has been "essentially eradicated," according to Washington State University researchers, the disease — in livestock and in people — remains a significant global concern. Now, Washington State researchers have been awarded a $2.75 million grant to explore how bacterial proteins work together to cause one of … Continue reading Brucellosis study targets cellular function

Method finds missing data in precision livestock systems

Photo: Swedish University of Agricultural Sciences. With the growing adoption of precision livestock farming practices and artificial intelligence in animal handling systems, a great deal of data is generated, but as is the case in many "big data" applications, there are missing data points that need to be accounted for. According to Keni Ren, a … Continue reading Method finds missing data in precision livestock systems

Bioactive compounds aid calf gut development

Photo by cottonbro on Pexels.com Feeding calves transition milk instead of milk replacer in the first days of life may stimulate intestinal development and improve health scores, according to a study published by Michigan State University researchers in the Journal of Dairy Science. For the study, the researchers examined the effects of transition milk — … Continue reading Bioactive compounds aid calf gut development

Model suggests ruminant methane pathways

Credit: Tohoku University Minimizing the amount of greenhouse gases emitted by livestock, particularly cattle, has been an important research theme, and this requires fully understanding the pathways by which enteric methane is produced. A collaborative project in Japan has employed biomarkers to describe the metabolic and nutritional characteristics linked to enteric methane emissions in Japanese … Continue reading Model suggests ruminant methane pathways

Less methane? Spent brewer’s yeast may benefit livestock sustainability

Photo by Skylar Kang on Pexels.com The animal feeding industries are built on upcycling surplus, spent and discarded foods and ingredients. Over the past century as this practice developed, much of the rationale was because these ingredients were available, cheap and had nutrients. Now, though, research is showing that some of these leftovers may provide … Continue reading Less methane? Spent brewer’s yeast may benefit livestock sustainability
