What you do—or don’t do—in the first few minutes after a new calf is born, can impact her health & performance for the rest of her life.

“Events in the first 15 minutes after birth can make a lifetime of difference for newborns,” says Amanda Fordyce, a technical dairy calf consultant with Milk Products, Chilton, Wisconsin. She lists 6 key areas to help calves get off to their best start:

Assistance at Delivery. The natural inclination is to help in delivery as soon as the calf’s front hooves appear. Doing so can cause more harm than good, and interferes with some important natural processes. When cows deliver naturally, they often pause for a few minutes after the calf’s ribcage appears and the calf takes its first breath. At this point, the placenta transfers its blood supply, about one pint of blood, to the calf. This transfer is crucial for timely placenta expulsion and a thrifty calf, says Fordyce. “As long as the cow is progressing normally and the calf is in the correct position, with no signs of stress from the cow or the calf, the best strategy is to monitor the process,” she says.

First Breaths. If the calf is not breathing, use a clean piece of straw in the nostrils or pour cold water on the calf’s forehead. Sit the calf up on its sternum by tucking the front legs under the body. “This sternal recumbency position helps ensure airways are open and make it easier for calves to breath,” says Fordyce.

Dangling calves. Some believe every newborn calf should be lifted upside down to help clear fluids from lungs. “Research has shown this practice does indeed expel fluids, but they are contents of the stomach—not the lungs,” says Fordyce. Upending the calf actually causes more stress to the animal. Internal organs press against and crush the diaphragm, making it more difficult for her to breathe.

Stillbirths. “Some calves may be born not breathing but still have a heartbeat,” she says. Check for the heartbeat by feeling the heart under the left leg on the rib cage. If you feel even a slight beat, vigorously rub the calf’s chest and use the straw-poke or cold- water techniques to stimulate her. You’ll be surprised how many calves ‘wake up’ and perform just fine, says Fordyce.

Warming boxes. “In instances of very cold weather, warming boxes are necessary,” she says. “But... TWO PROBLEMS: "...they can actually harm calves in the long run if used for too long or not clean enough.”

(1) Warming boxes become reservoirs of harmful bacteria that can easily infect susceptible newborn calves.

(2) Bring them in the House?? Spending 48 hours or more in a warm box--or if you bring them in the house--can deplete newborn calves’ internal stores of brown fat, leaving them less capable to adjust, when moved back out in the cold. Fordyce recommends using warm boxes sparingly, only until the calf’s hair coat is dry, up to 24 hours. Consider using a calf jacket or extra bedding in frigid conditions when temperatures are below 30°F.

Colostrum. “Calves can absorb critical antibodies and other immune factors from their dams only through colostrum,” says Fordyce. That ability begins to drop by 6 hours, and drops rapidly after 24 hours. Once the calf is breathing normally, make sure that calf is up and bonding well nursing the momma. It needs to receive 3 to 4 quarts of high quality colostrum within its first 2 hours of life. If the pair, or you can't get momma's colostrum to the calf, you will have to provide it. The colostrum should have a Brix refractometer reading of 22 or higher to ensure adequate quality. Consider keeping a separate collection of sanitized bottles, nipples and esophageal feeders for colostrum feeding only. If you can’t milk the calf’s dam immediately, consider using colostrum from other dams or a high-quality colostrum replacer with 150 grams IgG per dose, she says. ~ Jim Dickrell Thursday, March 08, 2018.

How to Dehorn Calves with Paste. If a calf needs to be dehorned, of all the various dehorning methods, dehorning with paste is the humane, easy, effective, and economical choice. It is low-stress to the calf. IMPORTANT: Apply dehorning paste before calves are 2 days old. Why: After 2 days, a calf has figured out how to scratch its head against something to rub the paste off, and, it can stand balanced on three legs to scratch it with its hind foot.
