Embryos were more likely to be of high quality when cows had lower progesterone levels at insemination and when more sperm reached the embryo. Younger cows and those with higher progesterone levels had lower chances of successful fertilization.

As One Health programs linking human, animal, and environmental health become more common, it's unclear how they're evaluated when rolled out on a large scale. Most programs focused on humans and animals (few included the environment), and a variety of methods were used to assess their success. The findings highlight the complexity of evaluating these initiatives and the need for flexible, comprehensive approaches to guide future efforts.

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.

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.

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%.

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.

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.

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.

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.

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.
