Superior calf performance begins during the birthing process in the maternity pen. Based on the 2017 USDA NAHMS Survey, five to seven percent of all newborn calves are stillborn or die within the first 48 hours. To improve calf survival after birth, we must follow practical, consistent calving protocols and provide a clean, dry calving environment.
One of the simplest best management practices we can do for the newborn calf is navel care. Previous University of Minnesota research showed in a controlled study that umbilical cord care significantly reduced the risk of developing umbilical cord infections.
As operations grow, or focus more on the milking herd, it has become a necessary component in moving newborn calves from the farm to a separate calf raising facility, some being out of state. Handling and transporting these calves can be stressful. However, there is limited research on the impact of long-distance travel on a newborn calf’s welfare.
Hoof health is essential for not only the overall health of the animal, but also for her welfare. Digital dermatitis (DD), or hairy heel warts, is an extremely painful condition for dairy cattle, reducing their ability to walk to and from the milking parlor, or to the feed bunk. Based on USDA NAHMS 2017 data, 16.8% of all cows and 2.6% of bred heifers have lameness on a dairy operation.
By Donald C. Sockett, DVM, MS, PHD, DACVIM (large animal); Wisconsin Veterinary Diagnostic Laboratory, UW-Madison It is important for livestock barns, calf pens, and calf feeding equipment to be properly cleaned before the disinfectant is applied. If surfaces are not properly cleaned, the disinfection step is much less effective at killing disease-causing microorganisms. Many disinfectants […]
English | Spanish El tiempo caliente puede traer una larga lista de problemas para las productoras lecheras. Cuando las vacas están sobrecalentadas, se comen menos, producen menos leche, tienen función inmune reducida y recuento de células somáticas levantado y muestran fertilidad reducida.
