Association between genomic daughter pregnancy rates and reproductive parameters in Holstein dairy cattle

Cows with higher Genomic Daughter Pregnancy Rate scores were more likely to get pregnant and less likely to lose a pregnancy, suggesting that selecting cows with better genetics for fertility could improve reproductive outcomes on farms.

Association between Pet Ownership and Mental Health and Well-Being of Canadians Assessed in a Cross-Sectional Study during the COVID-19 Pandemic

While pet owners initially appeared to have worse mental health and well-being, these differences disappeared once factors like age, income, and health were considered—suggesting no clear link between pet ownership and well-being during the COVID-19 pandemic.

Assessment of the evolution of the proportion of respiratory and enteric pathogens and diseases in pre-weaned unvaccinated dairy heifers from Québec, Canada

In their first two weeks of life, 18% of unvaccinated dairy heifers had respiratory issues and 23% had diarrhea. At 4 to 8 weeks, respiratory issues increased significantly to 62%, while diarrhea decreased to 13%.

Randomized controlled trial of pegbovigrastim as an adjunct therapy for naturally occurring severe clinical mastitis cases in dairy cows

Cows with severe mastitis treated with pegbovigrastim, along with standard antibiotics and anti-inflammatory drugs, were more likely to survive the first 30 days after treatment than those given a placebo. However, the treatment did not improve milk production or bacterial cure rates.

Technical note: Validation of an in-house bovine serum enzyme immunoassay for progesterone measurement

We developed a safe, in-house lab test to measure serum progesterone and compared it to both a commercial test and the standard method. The in-house and commercial tests worked well overall, especially at moderate to high hormone levels, and the in-house test proved to be a reliable alternative.

Microbial contamination and associated risk factors in retailed pork from key value chains in Northern Vietnam

Overall, 58.1% of retailed pork in Vietnam was contaminated with Salmonella, and only 6.2% pork samples met the Vietnamese standard requirement for TBC contamination. Transport time, pork arrangement, storage condition and environment hygiene could affect microbial contamination.

Symposium review: Linking activity-sensor data and physiology to improve dairy cow fertility

Research shows that cows showing stronger and longer signs of heat (estrus) are more likely to get pregnant and keep the pregnancy. Using activity monitors to track these signs can help farmers improve breeding success and even tailor treatments to individual cows. As technology advances, this data could help refine breeding decisions and may even influence future genetic selection for fertility traits.

Prevalence of shedding and antibody to Coxiella burnetii in post-partum dairy cows and its association with reproductive tract diseases and performance: A pilot study

About 13% of cows showed signs of past exposure to Coxiella burnetii, mostly older cows, while no active infections were found. Although no strong links were found between infection and reproductive problems, the results provide useful early data for larger studies exploring how this bacterium might impact fertility in dairy cattle.

Gap between producers and veterinarians regarding biosecurity on Quebec dairy farms

Most veterinarians reported it was easy to discuss biosecurity with their clients, but most veterinarians and producers did not actually discuss biosecurity. When they both reported biosecurity was discussed, there was no agreement between the pairs on the topics discussed. Veterinarians also misjudged how their clients perceived the importance and usefulness of biosecurity.
