“Isn’t she just so cute,” is not the best statement when seeing a doe and twin fawns eating farm-stored feed on an early August morning. Deer movements studied by scientists with USDA National Wildlife Research Center and Michigan State University showed more visits by deer to farm-stored feed in December and January than in the fall or spring. But, what stood out in the data … [Read more...]
Heat stress brings lasting impacts in dairy cows for years
Heat stress in dairy cows is a timely topic. Recent research coupled with dairy producer experiences show impacts on the milking cows’ milk production, as well as a developing calf inside a heat-stressed dry cow. Source: Dairy Herd Management, June 21, 2017. A phenomenon called fetal programming means the DNA of the calf born from a dam who was heat stressed is permanently … [Read more...]
Accelerated calf growth programs, economics and effects
Jud Heinrichs, Penn State Dairy Extension, writes that feeding the dairy calf and heifer can be likened to a double-edged sword; we want to feed the heifers as much as possible to get rapid growth so that they begin lactating early in life, with a large body size at calving relative to their mature weight. However, there are issues related to rapid growth and a high level of … [Read more...]

Time-lapse cameras improve dairy feeding
“Moo,” you’re on candid dairy camera. It brings up silly images, but time-lapse photography is proving valuable for monitoring and correcting feed delivery to dairy cows.

Bedding, bugs and teats
In spite of solid progress to lower somatic cell counts on dairies, many farms continue to struggle with clinical mastitis. In fact, clinical rates of mastitis have nearly doubled over the last two decades, from about 13 cases per 100 cows to 24, says Pam Ruegg. Cow-to-cow mastitis spread is not the core challenge today. Rather, herds must now deal with bacteria that live and … [Read more...]
Sponsored Content – Pathogen-based mastitis management
A pathogen-based approach to managing mastitis uses on-farm cultures to characterize infections within 24 hours. This allows managers to leave some cattle untreated and use lower-cost treatments on some cattle, with lower treatment costs and less waste milk contributing to the cost savings.

Respiratory disease part of cold weather aftermath
Cold temperatures often bring an increase in sick calves. There are physiologic reasons why it increases the risk of respiratory disease. This should prompt caretakers to further tune in more to the health of their calves. Early detection and treatment is important to calves’ immediate health as well as to long-term production.

Manage to minimize lameness
Marcia Endres, dairy specialist at the University of Minnesota, acknowledges lameness will never fully be eliminated from dairy herds, but producers need to be proactive to reduce its incidence.

Revive a cold newborn calf with ice water
Dr. Sheila McGuirk says ice water is a handy way to get a struggling calf on the road to warmth. Calves that don’t score well on a vitality scale need stimulation to avoid hypothermia.

Bigger is not better
Larger dairy cows don’t necessarily mean they will feed efficiently. Size and yield in dairy cows are not genetically correlated, says Lou Armentano, a University of Wisconsin dairy nutritionist.

Verify clostridia before implementing prevention strategies
Sheila McGuirk, University of Wisconsin emeritus professor of veterinary medicine discussed clostridial disease during a recent Dairy Girl Network winter calf webinar.

If diarrhea does break, it … [Read more...]
Winter brings lousy conditions, literally
“Lice are the forgotten winter parasite,” Jerry Bertoldo said. “They tend to ‘bloom’ during the initial surge of cold weather. Lice will be more obvious after calves are weaned, although their exposure may have happened as early as the calving pen,” he said. Source: Dairy Herd Management, November 10, 2016. Bertoldo said visual diagnosis of lice is challenging because they … [Read more...]
