Animal health

With colder temperatures, we are seeing a significant increase in bird pressure on dairy farms. Birds have always been a concern on dairy farms, but the onset of avian influenza virus type A (H5N1) has brought a greater spotlight to the issue.

A balanced diet is crucial to a dairy farm’s success, and managing all the variables that come with feeding cows is just as important. Variation can exist within forage piles, ingredients, feed mixing and delivery, and at the feedbunk. It doesn’t matter if a ration is perfectly formulated if these other factors keep cows from eating it.

Much of the Midwest has seen a rise in heat and humidity in the past couple of weeks. The effects of summer heat and humidity are well-documented in lactating dairy cows as we see decreases in dry matter intake and subsequent production losses. Newer research points to the value of heat abatement and cooling practices for dry cows.

By Noah Litherland, Ph.D. | Heifers have specific nutrient requirements for maintenance, growth and eventually pregnancy. Forages serve as the foundation for the heifer diet and must be selected with heifer nutrient requirements in mind.

By Bethany Dado-Senn, Ph.D., and Lucas Mitchell, Ph.D. | The birth of a calf signals the start of a 24-hour race to ensure the foundation of a strong immune system. 

By Lucas Mitchell, Ph.D., Vita Plus | Calves are quite susceptible to disease in their first four weeks of life. How these challenges are combatted varies from farm to farm, but a couple of items consistently ring true.

By Barry Visser | This winter has presented us with nearly every weather scenario possible: fluctuating barometric pressures, bitter cold temperatures and wind chills, and mild temperatures with rain, ice, and fog. These changing weather systems have an impact on dairy cows and milk production. There are a few management considerations to minimize the impact of cold stress on milk production.

Dr. Bethany Dado-Senn | If your farm has a seasonal decrease in colostrum production across the late-fall and early-winter months, the following proactive steps can help you maintain a constant supply of high-quality colostrum for your valuable replacement herd.

Dairy producers and industry peers gathered together June 15 and 16, 2022, in Wisconsin Dells, Wisconsin, to network and gain practical insight from agricultural leaders. This e-news provides summary articles from the event sessions.

During their presentation and udder dissection lab at the Vita Plus Midwest Dairy Conference, Dr. Meghan Connelly, Vita Plus, Dr. Kolby McIntyre, Marsh View Veterinary Clinic, and Dr. Matt Schaefer, Waupun Veterinary Service, discussed udder health and its relationship to milk quality.

Dr. Kendra Wells is a leader in the use of lung ultrasounds to identify potential respiratory challenges in calves and make valuable management decisions.

Tim Kerfeld, J Hall, and Rebecca Davis own and/or manage vastly different operations, but all are intensely focused on the long-term success of their farming businesses. They compared their management strategies during a producer panel at the Vita Plus Midwest Dairy Conference.

By Barry Visser Now is the time to make fly control plans for your operation. Flies are a nuisance to farm workers and animals, transmit disease and cause significant economic loss. Flies cause livestock to expend extra energy fending them off instead of resting, feeding and milking. Fly control is critically important to all dairy operations to reduce the spread of disease and improve animal comfort, resulting in decreased stress and greater efficiency of growth or production. 

By Barry Visser Temperature fluctuations this winter have presented challenges for calf raisers across the Midwest and many farms have seen an uptick in respiratory issues. Many calf barns rely on natural ventilation to provide clean, fresh air to the calves. This works well in the summertime; however, as doors, windows and curtains are closed in the winter, providing sufficient air exchanges to keep calves healthy can be challenging.

By Ann Hoskins Maternal colostrum is a high-value asset on your farm. Unfortunately, that asset often runs short this time of year as many farms see a slump in colostrum production between November and February. Farms need to have a “plan B” in place as they don’t want to short calves on this vital nutrition.
