No fly control or tick control measure should be considered a “one-and-done” strategy, writes Beth Reynolds. With summer in full swing, now is an ideal time to review what strategies were used for prevention, if those strategies actually impact ticks or flies, and the effective window for each. Reynolds’ review of prevention methods, habitat modification and reproductive … [Read more...]
Keep water clean on dairies for cows’ safety
Reinforcing the importance of clean water, Russ Cavanaugh addresses the potential of water as a fomite. He contrasts how most poultry and hog producers approach water treatment with a relative lack of water treatment systems on dairies. His article is a call to action for dairy operators to know what is in their water and to devise a treatment and monitoring system to ensure … [Read more...]
Build cows that stay: Smarter heifer development for long-term productivity
Early conception during the first breeding season is one of the most important predictors of lifetime productivity and retention in heifers. Kacie McCarthy explains that long-term cowherd performance comes from managing heifer development as part of the whole system. Early conception, environment, nutrition, age at first calving and body condition all work together to influence … [Read more...]
Start with foot baths to reduce lameness
Some dairy producers gauge the impact of lameness by the number of cows requiring treatment, but Abbie Goldenberg with Farm Inc. believes that measure misses the bigger picture. Experts say better hoof bath management is what keeps cows healthy in the first place as noted in this article about proper footbath design and maintenance. Aerica Bjurstrom with the University of … [Read more...]

Only a third of summer milk loss comes from the bunk
Cooling is necessary; it’s just not sufficient, writes Andrew Hunt. His article is one to study and share with dairy producers. Just one heat event starts a cascade resulting in milk losses. Only about a third of summer milk loss traces back to reduced intake. The rest comes from a gut–immune cascade cooling fans can’t touch. When a cow shunts blood from her gut to dump … [Read more...]
Liver abscesses not just a harvest-day finding
It is now believed the true impact of liver abscesses may begin long before harvest. Shifting energy use from maintenance to production and growth is central to the discussion of liver abscess.

25 heifer candidates are better than 10 replacement heifers
Stop only picking replacement heifers one time at weaning. Evaluate heifer candidates at five critical phases and let selection pressure identify your herd's future, writes Wesley Tucker. He asserts that producers continue sacrificing their younger, better-genetic heifers by selecting replacements too early and limiting a more natural selection process over the heifer … [Read more...]
Review: Why bird flu targets cows’ udders instead of lungs
In cows, the bird flu looks completely different. Instead of affecting the lungs, as H5N1 does in other mammalian species, it causes severe infection in the cows' udders and largely spares the lungs. Researchers revealed the biology of why the disease looked so different when it leaped to cows, and offer a framework for spotting its next guise more quickly in this … [Read more...]
Fear of rabies spreading in Upper Midwest cattle herds via skunks

Those #@$^&! flies
University studies routinely show that heavy fly pressure changes cow behavior and lowers production. Good fly control starts with sanitation and manure management. Clean facilities, dry bedding, strong airflow and regular monitoring all reduce fly pressure.
