Survey suggests variation in vitamin/trace mineral use in swine diets

There are recommended inclusion levels for vitamin and trace minerals in livestock rations, and then there are the actual inclusion levels for vitamin and trace minerals in livestock rations. Photo by Mark Stebnicki on Pexels.com Sometimes, due to cost, nutritionists and/or producers will include a lower level of one or more of these micronutrients, hoping … Continue reading Survey suggests variation in vitamin/trace mineral use in swine diets

Barnyard Roundup: Potential oilseeds; milk fat; fish feed

Holstein cows shown at the Penn State Dairy Barns. Milk fat is a main contributor to the value of milk, but it is also the most variable component because it is very responsive to diet and management,  Credit: Penn State. Creative Commons As the name suggests, oilseed crops are grown for their oil content — … Continue reading Barnyard Roundup: Potential oilseeds; milk fat; fish feed

Novel feeding concept aims to improve swine microbiota, reduce methane

Photo by Leah Kelley on Pexels.com A new research and innovation project will see Aarhus University in Denmark and Danisco Animal Nutrition & Health, part of IFF's Health & Biosciences division, develop a novel feeding concept to improve the swine gut microbiota — i.e., the microorganisms living in the gastrointestinal tract in pigs. The aim … Continue reading Novel feeding concept aims to improve swine microbiota, reduce methane

Gut microbiome stabilizes a week after ration changes

Photo by MART PRODUCTION on Pexels.com When studying the dietary effects of a new ingredient or ration processing, an adaptation period is typically included before collecting datapoints so the true effects of the novel ingredient can be understood. The length of this adaptation period has been open to debate and will depend on species and … Continue reading Gut microbiome stabilizes a week after ration changes

Got necrotic enteritis? Specialty corn may reduce intestinal disease in chickens

The anti-inflammatory and antibacterial properties of flavonoids may play a key role in the control of disease. Penn State researchers suggest that high-flavonoid corn may serve as an effective alternative for improving health and performance in the absence of antimicrobials in chickens.  Credit: Gino Lorenzoni/Penn State. Necrotic enteritis is one of the most devastating diseases … Continue reading Got necrotic enteritis? Specialty corn may reduce intestinal disease in chickens

Barnyard Roundup: Pig weights and chicken welfare

The study group of pigs at the Texas A&M Department of Animal Sciences facilities are being provided a dietary supplement of arginine and creatine. (Texas A&M AgriLife photo by Laura McKenzie) Two amino acids plus a metabolite — arginine, methionine and creatine — are showing great promise in improving the overall litter weight and health … Continue reading Barnyard Roundup: Pig weights and chicken welfare

Barnyard Roundup: Methane-based feeds and antimicrobial soy

The sprouting soybeans, in front, have been inoculated with a pathogen to trigger production of glyceollins, which have antimicrobial properties. Scaling up these lab experiments at the POET Bioproducts Institute may lead to soybeans that are rich in glyceollins being integrated into animal feed to help prevent disease and reduce the need for antibiotics. Photo: … Continue reading Barnyard Roundup: Methane-based feeds and antimicrobial soy

Barnyard Roundup: Forages, pigs, sheep & dairy cows

Photo by cottonbro on Pexels.com In the Northern High Plains, the crop and livestock industries are limited by market accessibility, infertile soils, and short growing seasons, so adding a new type of crop to rotations could help maintain the sustainability of the region. A research team at the University of Wyoming is researching whether sunn … Continue reading Barnyard Roundup: Forages, pigs, sheep & dairy cows

Barnyard Roundup: Microbiomes, metaphylaxis & endemic pathogens

Photo by Edward Jenner on Pexels.com Researchers with the Arkansas Agricultural Experiment Station have developed bacterial cultivation methods to isolate different bacteria from pigs, which can be used to culture beneficial bacteria from swine intestinal microbiomes to serve as probiotics to protect or improve swine health. Guided by these methods, the researchers isolated three bacterial … Continue reading Barnyard Roundup: Microbiomes, metaphylaxis & endemic pathogens

Barnyard roundup: Grazing sheep, reducing wildfire, recycling phosphorus

Recently grazed paddock (right) and the paddock sheep including a guard llama were moved to the same day, with complete fence setup still in progress. Notice the relative tall canopy in the already grazed paddock to ensure minimum exposure to parasites and as much leaf material as possible for a speedy regrowth.
