By Jon Rasmussen | Research has shown reduced sorting, elevated lying times, positive milk responses, and enhanced milk component responses are all possible with more feed deliveries and feed pushups. One of the simpler technologies we can use in observing feedbunk behavior and feed pushups is a time-lapse camera, which allows us to observe cows at a distance.
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.
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.
Luke Laufenberg has joined his father and uncle full-time on the family farm and “technology implementer” is one of his many roles. Laufenberg shared the benefits of AMS his family has seen during his presentation at the Vita Plus Midwest Dairy Conference.
By Dr. David Carlson Heat stress presents many challenges for dairy farms, including diminished milk production, reduced reproductive performance and stressed cow wellbeing. Long-term impacts can be felt for years in terms of the health and productivity of offspring. Prioritize your heat abatement options by identifying maintenance needs of existing systems as well as high-value

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.

Many different species of birds make a dairy farm “home” in the cooler months, posing a risk to the health of livestock and people as well as the farm’s bottom line. Birds are drawn to farms because of the continuous supply of fresh feed and seek the energy-dense components of the feedstuffs or ration. This loss of nutrients consumed by birds can greatly impact the nutrients that cattle are able to eat, thus directly impacting a producer’s bottom line. In addition, birds are associated with the spread and amplification of microbiological hazards, including E. coli, Salmonella, and many others that can have lasting impacts in dairy herds.

If you are deciding to build a new forage storage site, such as a pile or bunker, it is important to consider the space required for these structures, the amount of forage you need at the present time and in the future, and your desired feedout rate. Additionally, adding adequate apron space is another component often overlooked.
The owners of Hilltop Dairy LLC in Markesan, Wisconsin, have had a passion for registered Holstein cattle and “good-looking, good-producing cows” for decades. That tradition continues to be front-and-center on the 1,400-cow dairy today.

After just a few hot days, it is not uncommon to see milk production losses of 5 to 15 pounds of milk per cow day. That might be just the tip of the iceberg as heat stress can lead to a long list of other animal health and performance consequences. A lot of factors go into designing heat abatement systems for dairies, which require a solid understanding of your facilities and environment. Here are some very common areas that we can focus on to help us prioritize where to start.

In the most recent edition of Starting Strong Calf Chat, Dr. Noah Litherland reminds calf raisers of three goals of ventilation: (1) provide adequate amounts of clean air to the calf, (2) prevent drafts on the calf, and (3) manage the temperature and humidity in the barn.

As robotic milking systems continue to gain interest and adoption, dairy producers are looking at the economics associated with the technology. Producers often ask us, “What truly influences milk production on a robotic dairy? Do pellet characteristics influence visits and milk production? Does the energy density of the partially mixed ration (PMR) affect milk production?”
During Vita Plus Dairy Summit in December, attendees explored many “waves of change” in the dairy industry. If you did not attend the event – or did attend and are looking for a refresher – browse the topics in this post to access the full event e-news.

If you haven't already, now is the time for routine maintenance on your calf facility ventilation system. Good air quality goes a long way in promoting calf health. Plus, an efficiently working ventilation system saves dollars on your bottom line.

Every one of us in the dairy industry has an inborn fondness for cattle, and value newborn calves and the promise they bring. Let’s get wise about thermal support for our calves in the first 24 hours of their lives during cold weather.

Dairy cattle behavior and appearance often make it easy to detect external parasites like flies, mange and lice. Severe internal parasite infiltrations can result in roughness of hair coat, anemia, edema and diarrhea. However, the subclinical impact of internal parasites is largely hidden, yet costly. According to a recent study at Iowa State University, undetected subclinical disease caused by internal parasites can cost $190 per animal.
