In brief: HPAI; offshore mussels, cattle efficiency, trout

Highly pathogenic avian influenza (HPAI) cases continue to rampage across the country, though numbers so far in October is lower than in September. So far in October, as of Oct. 22, almost 833,000 birds were culled, including more than 527,000 turkeys, with a significant number of backyard flocks affected, particularly in the West, but backyard … Continue reading In brief: HPAI; offshore mussels, cattle efficiency, trout

Vaccines possible for prion diseases

Photo by LuAnn Hunt on Pexels.com At the University of Saskatchewan's Vaccine & Infectious Disease Organization (VIDO), Dr. Scott Napper has a lead role in the search for vaccines to treat diseases caused by misfolded proteins known as prions. His original research focused bovine spongiform encephalopathy in cattle, scrapie in sheep, and chronic wasting disease … Continue reading Vaccines possible for prion diseases

Pastures: To burn (a patch) or not to burn (the whole thing)?

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)?

Barnyard Roundup: Ethanol emissions, corn nutrient use efficiency

Photo by Alejandro Barru00f3n on Pexels.com Efficient use of inputs and limiting the emissions of undesirable compounds has been a major research area in the last decade, and new tools and techniques are advancing progress in the area. On the crop side, expensive fertilizer inputs increase crop production but often excess nutrients remain in soils. … Continue reading Barnyard Roundup: Ethanol emissions, corn nutrient use efficiency

Got weeds? Invasive plants tracked from space

Leafy spurge growing in Southwestern Minnesota. Credit: Thomas Lake When I was a county agricultural extension agent in rural South Dakota in the mid-1990s, the county employed an invasive weed control officer whose job was to drive around the county on the look out for "noxious plants" on the state's regulated plant list. His particular … Continue reading Got weeds? Invasive plants tracked from space

Cattle feedyard to test sustainable technologies

Credit: USDA-Agricultural Research Service The true test of any new technology is to install it into a large-scale, commercial operation. Most technologies are developed in a virtual vacuum, which is necessary to ensure that the new system functions as designed, and after the testing phase, they are moved to practical, in-field testing. In the last … Continue reading Cattle feedyard to test sustainable technologies

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

Diesel nut research aims for lower carbon-intensity fuels

Texas A&M AgriLife Research’s “diesel nut” variety increases. (Texas A&M AgriLife photo by John Cason) Typically, "diesel fuel" refers to a petroleum product, but increasingly, various biodiesel blends are on the market, usually based on some combination of animal fat and plant (e.g., soy) oils. Now, Chevron and Texas A&M AgriLife are collaborating to develop … Continue reading Diesel nut research aims for lower carbon-intensity fuels

New Canada living labs seek on-farm solutions to climate change

Photo by RGR G. on Pexels.com Last week, the government of Canada announced nine new living labs established across Canada that aim to help reduce greenhouse gas emissions and strengthen the climate resiliency of food systems. With an investment of $54 million under the Agricultural Climate Solutions (ACS) – Living Labs program, this first wave … Continue reading New Canada living labs seek on-farm solutions to climate change
