As I write this, we’re settling in for a heat wave and I anticipated leading off with an article regarding heat mitigation, or perhaps the impacts of heat stress on livestock.

Our Continuing Education program is built around “3 V’s” – Vision, Visibility, and Value.

Although only 1-5 % of infected cattle develop malignant lymphoma, bovine leukosis is one of the most prevalent diseases in dairy cows.

Emissions of greenhouse gases (GHG) such as methane have clearly become a major topic of discussion.

• Shifts in uterine microbiome associated with pregnancy outcomes at first insemination and clinical cure in dairy cows with metritis
• The association between bovine leukemia virus infection and metritis in dairy cows
• Differences in lactational performance associated with antimicrobial therapy and clinical cure of metritis in dairy cows
• Clinical cure failure of metritis is not associated with differences in the uterine metabolome of dairy cows
• Peripheral leukocyte transcriptomic changes in preweaned Holstein dairy calves with varying stages of Bovine Respiratory Disease

• Antimicrobial Resistance Genes in Respiratory Bacteria from Weaned Dairy Heifers
• An artificial intelligence approach of feature engineering and ensemble methods depicts the rumen microbiome contribution to feed efficiency in dairy cows
• Investigating relationships between the host genome, rumen microbiome, and dairy cow feed efficiency using mediation analysis with structural equation modeling
• Characterization of the preweaned Holstein calf fecal microbiota prior to, during, and following resolution of uncomplicated gastrointestinal disease
• Shifts in uterine microbiome associated with pregnancy outcomes at first insemination and clinical cure in dairy cows with metritis
• Dietary supplementation of rumen native microbes improves lactation performance and feed efficiency in dairy cows

• When “out on pasture” isn’t picturesque
• Porcine reproductive and respiratory syndrome virus (PRRSV) in swine herds in the United States
• Analysis of transcriptional changes in peripheral leukocytes from pre-weaned Holstein dairy calves with respiratory disease
