Diarrhea, or scours, accounts for over 50% of illnesses in preweaned calves, contributing to 32 percent of all deaths in calves (USDA NAHMS 2014 Preweaned Calf Component Survey). Scours itself does not usually kill the calf. Rather, the calf will succumb from the dehydration and electrolyte imbalances which follow. Early identification of affected calves and early and aggressive treatment with fluids and electrolytes is the most successful way to treat scouring calves.
Providing an excellent environment is a key component in successfully raising calves. For calf housing the environment includes the calf’s resting space, feeding, and walking surfaces. A clean, dry resting surface ensures a hair coat that helps insulate the calf against the cold, low air temperatures,and sudden changes in temperature.
Winter weather brings new challenges for completing chores on the farm. Calf care is no exception. Calves perform best when we acknowledge their needs change in colder weather and adjust our management accordingly.
Animal care and welfare starts on day one with the newborn calf. Healthy calves are the cornerstone of every dairy operation, not only providing the future genetics for the herd but healthy calves are also important to the vitality of the dairy farm.
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.
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 […]
Want to learn about the latest research on calf housing? Two heads are better than one: A starter guide to pairing dairy calves This series of articles is a seven-part starter guide for pairing or group-housing pre-weaned dairy calves. Throughout this guide, we cover best practices to promote good health and welfare in calves raised […]
When we talk about thermal stress in pre-weaned calves, often we discuss cold stress. However, calves can become environmentally stressed when temperatures are too cold or too hot. During extreme cold or hot temperatures, calves utilize extra energy to maintain their core body temperature. The temperature range at which a calf uses no additional energy […]
Feeding high-quality colostrum to the calf as soon as possible after birth is the most important thing you can do for calf health. It is especially important for dairy and beef x dairy calves destined to leave the farm at a young age to receive colostrum.
