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

Probiotic combo ‘drastically’ improves oyster larvae survival

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

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

Blue catfish genome mapped

Auburn University postdoctoral student Baofeng Su is part of an Auburn research team that recently became the first to map a high-quality genome assembly of the blue catfish. Photo: Auburn University. Catfish farming is the largest aquaculture industry in the U.S., accounting for approximately 70% of the nation’s total aquaculture output, according to Auburn University … Continue reading Blue catfish genome mapped

Barnyard Roundup: Pig DNA, antimicrobial data & fish research

Photo by Mark Stebnicki on Pexels.com Genomic advances are offering greater insights into the biology of farm animals and providing new tools to help advance production practices. For example, researchers from the Roslin Institute in Scotland and the Centre for Tropical Livestock Genetics & Health sought to find and examine regions of DNA that regulate … Continue reading Barnyard Roundup: Pig DNA, antimicrobial data & fish research

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.

Barnyard Roundup: Horn fly resistance, poultry complexes and bivalves

A study conducted by scientists in Penn State’s College of Agricultural Sciences explored genetic parameters and genomic regions associated with horn fly resistance in organic Holstein cattle. Credit: Bailey Basiel/Penn State. Creative Commons Some Holstein dairy cattle, particularly those with white coat coloration, naturally fend off the horn fly, a parasitic insect known to cause … Continue reading Barnyard Roundup: Horn fly resistance, poultry complexes and bivalves

Barnyard Roundup: Intensively managed grazing, perennial forages, anaplasmosis test

Cows from the SDSU Cottonwood Field Station graze during the summer on leased pasture at the Fort Meade National Recreation Area near Sturgis. Photo: South Dakota State University. Intensively managed grazing has gained popularity among cattle ranchers as a way to optimize animal performance while improving pastures and rangelands. Now research from South Dakota State … Continue reading Barnyard Roundup: Intensively managed grazing, perennial forages, anaplasmosis test

Barnyard Roundup: Cattle reproduction, wild pigs and resistance genes

Photo by Diego F. Parra on Pexels.com If reproduction is unsuccessful, animal agriculture is unsuccessful. Regardless of species, reproductive inefficiency costs the industry billions of dollars in wasted resources and lost income. Texas A&M researchers, as well as others, have been studying cattle pregnancy to determine solutions. Much of the U.S. — especially the Southeast, … Continue reading Barnyard Roundup: Cattle reproduction, wild pigs and resistance genes

Barnyard roundup: Better understanding emissions, animal disease research

Cost-effective ways could be found to reduce the emission intensity of farmed Scottish salmon. Photo: SRUC.   Scotland's Rural College (SRUC) has determined that farmed Scottish salmon has a similar carbon footprint to chicken meat. The SRUC study estimated that the Scottish farmed salmon sector emitted 616,000 metric tons of carbon dioxide equivalent in 2019, … Continue reading Barnyard roundup: Better understanding emissions, animal disease research
