Starting Strong – Calf Care

By Ann Hoskins, Vita Plus calf products coordinator
Before you decide to turn that old dairy barn into a calf barn, you should do some research.  An old barn may provide more warmth and protection from the elements for calves and caretakers.  But consider calf flow, ventilation, sanitation, ease of feeding, and the overall health benefits and risks before you begin renovations.

Serum total protein analysis is a simple and repeatable way to evaluate passive transfer of immunoglobulins in dairy calves up to five days of age.  When colostrum is fed, the immunoglobulins are absorbed through the intestinal wall and into the bloodstream, where they interact with tissues in the body to provide passive transfer of immunity from the dam to the calf.

Question:  How can I slope hutches to increase drainage?

Quick answer:  Creating a 2-percent slope by placing a small mound at the junction of the calf hutch and outside pen increases drainage away from the calf.

Spring has arrived here in southern Wisconsin and we have been experiencing the wet conditions that come along with it. Based on the on-farm observations our team has made and discussions with veterinarians, I believe that respiratory disease has been the number one challenge as we enter spring. Along with that, an increase in Salmonella-related challenges have not only resulted in scours, but also have developed into respiratory issues in some herds. Salmonella can be transferred through saliva, milk, fecal-oral vectors, nasal contact and colostrum. Key factors that impact the spread of Salmonella are cleanliness and ventilation.

Estimating starter grain needs for your calf operation can be challenging.  For most farms, starter intake averages around 1.2 to 1.8 pounds per day for the 60-day nursery phase.  Starter intake increases as calves get older and typically peaks at 5 to 7 pounds at 60 days for Holstein calves.  Additional factors – such as surges in calving intensity, amount of starter grain shrink during rainy periods if calves are fed in pails outside, and the amount of starter grain fed to transition calves – all increase the complexity of estimating calf starter grain usage and inventory. 

We developed a simple Calf Starter Usage Calculator to help take some of the guesswork out of estimating the amount of calf starter needed.

It is not advisable to pressure wash or aerosolize water in calf areas.  Pathogens can easily travel with the mist that pressure washing creates.  Using a foamer is a great alternative.

We're seeing some overcrowding in heifer facilities right now, which can lead to health challenges if management protocols slip a bit.  Dr. Noah Litherland, Vita Plus dairy youngstock technical specialist, discusses some of the things you can do to keep your calves healthy through environmental challenges.

Genetic Excellence Realized Through Consistent Calf Care
As you might guess from the name, Wittenberg Embryo Transfer in Wausau, Wisconsin is not your average dairy farm.  Owner Dr. John Prososki purchased the farm about 10 years ago with about 25 cows.  The old red barn remains, but everything else has been built new as the herd has grown to about 160 milking cows.

Prososki is a veterinarian and started his career at a large animal practice before he began working exclusively in embryo transfer (ET) a number of years ago.

We're pleased to introduce you to Jonathon Hallock and the MarBec Dairy team from Mondovi, Wisconsin.  Throughout 2017, Jonathon will share his calf program and experiences with us.

The times they are a changin’ with MLV and killed vaccines.  It doesn’t have to be one or the other.

In the last 40 years, we have seen several waves in which type of vaccine - modified live vaccines (MLV) or inactivated (killed) - is the most efficacious and safe.

Historically, we believed bacteria functioned as individual cells.  The discovery of intercellular communication among bacteria led to the realization that bacterial communities are capable of coordinated activity.  The “language” used for this intercellular communication is based on self-generated signal molecules called autoinducers.  When sufficient bacteria are present, autoinducer signals allow bacteria to sense a critical mass or quorum.  Communication allows bacterial populations to synchronize group behavior and coordinate multicellular functionality.

Veterinarian Feed Directive (VFD):  It has been a buzzword in the livestock and feed industries to kick off 2017.

How has implementation of the VFD rule gone thus far? It might depend on who you ask, but it has taken a team effort between veterinarians, livestock producers and feed distributors alike – which is ultimately the intention of the law – to ensure judicious use of animal antibiotics.

As we embark on 2017, we find our industry under new regulations that influence the decision-making and day-to-day operations on many farms.  The Veterinary Feed Directive (VFD) requires additional traceability to use some common medications.

The Holstein steer feed and marketing world has experienced quite a bit of angst in the past couple months.  Basis on cash Holstein steers at the auction houses has widened to as much as -$45 per hundredweight (cwt) under colored cattle.  Typically, basis runs -$5 to -$7 under beef breed animals.  When you factor in the difference, you could be taking a hit of about $550 per head.
