Roundup: Cheese flavors and salmonella vaccines

Photo by NastyaSensei on Pexels.com New research conducted at the Tokyo University of Agriculture in Japan demonstrates that the flavoring of various soft cheeses is due in part to bacterial colonization during the ripening process. The research was published in Microbiology Spectrum, a journal of the American Society for Microbiology. As cheese ages, beneficial bacteria … Continue reading Roundup: Cheese flavors and salmonella vaccines

Spent coffee grounds help microalgae produce low-emission biodiesel

Photo by Lina Kivaka on Pexels.com Every day, billions of cups of coffee are consumed, contributing to a massive amount of spent coffee grounds that often end up in the trash. However, two researchers in the U.K. have determined that spent coffee grounds provide both nutrients to feed and a structure on which to grow … Continue reading Spent coffee grounds help microalgae produce low-emission biodiesel

First honeybee vaccine ‘game-changer’

Researchers from the UGA Bee Lab study hives. Delaplane says that honey bee vaccines would be a game-changer for beekeepers who have had few resources beyond supportive therapies for decades. (Photo by Keith Delaplane) Vaccines are a proven benefit in the world of animal science, and soon, it may be possible to vaccinate six-legged livestock, … Continue reading First honeybee vaccine ‘game-changer’

Artificial intelligence helps mitigate poultry heat stress

Photo by Alexas Fotos on Pexels.com It gets hot in Georgia, making heat stress a major issue for the state's significant broiler chicken industry. Chickens are raised on thousands of farms in Georgia and across the southeastern U.S., and those birds need to be transported to processing facilities when they reach market size. Transportation stress, … Continue reading Artificial intelligence helps mitigate poultry heat stress

Novel imaging method to assess bone strength in hens

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

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

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

Pig study slows biological processes of death

Photo by mali maeder on Pexels.com In a new study that will surely lead to controversy and misinterpretation, Yale University scientists have found that the cascade of biochemical events at death doesn't have to happen quickly. The findings, reported in the Aug. 3 edition of the journal Nature, may extend the health of human organs … Continue reading Pig study slows biological processes of death

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
