If a calf is rejected or having trouble nursing mama the first time, you need to milk some colostrum from the cow and feed it to the calf with a clean nipple bottle. “The key is warm water, not hot. You may need to download version 2.0 now from the Colostrum is also the perfect food because it has a much higher fat content than regular milk and gives the calf energy for strength and keeping warm if the weather is cold. Think preventatively.
Colostrum can be stored in the freezer and thawed slowly in warm water. These include calves that suffered prolonged birth, twins, and calves born to sick cows or cows in poor body condition.

Informa Markets, a trading division of Informa PLC. “Most calves I’ve seen with frozen feet were debilitated from some other reason, like scours,” Daly says. Middle photos: Inside views of the IX’s custom-designed and built multiple-calf warmer. If he’s perfectly clean and dry when you take him back to mama, she may not recognize his smell and won’t claim him as her calf.Several decades ago, some early-calving ranchers were losing calves to “weak-calf syndrome.” Studies in the 1970s determined it was primarily a problem in calves from young cows (two- and three-year-olds), caused by deficiency in dietary protein during late gestation.Robert Loucks (Lemhi, ID, Extension agent, now retired) worked with an interdisciplinary team studying weak-calf syndrome for 15 years.“In 1971-72, a research group from the University of Idaho led by Richard Bull collected and analyzed thousands of blood and tissue samples from healthy calves and weak calves, and samples from their dams, and found that weak calves – born from protein-deprived dams – were not physiologically normal,” Loucks says.The calves didn’t absorb antibodies from colostrum efficiently. These calves may freeze their feet at temperatures that would not be dangerous to a healthy calf.The quickest way to thaw a frozen calf is in warm water, but make sure it’s not too hot or it may damage skin that’s already compromised by frostbite. When calving early – as many western ranchers do, to have calves born and cows bred before going to public range – cows are on harvested feeds or supplements rather than green grass during the last crucial weeks of pregnancy.
Don’t wash all the amniotic fluid off a newborn calf (if you warm him in a tub).

They must be dried off as soon as possible, he says.A “warm” windy day can be deceptive, he adds, and you may not realize that drying a newborn calf is an emergency. Dr W Dee Whittier, Extension Veterinarian at Virginia Tech looks at how, with appropriate management, these losses can be A warming crate can be very beneficial for hypothermic calves,” Callan says.Boxes should be cleaned and disinfected between calves.“We’ve seen situations in which I suspect the (lack of) warming-box sanitation led to increased calf scours,” Daly says. Any stress – from cold or a difficult birth – can interfere with optimum absorption, leading to problems with scours, pneumonia and other infections.Robert Callan, professor of clinical sciences in the College of Veterinary Medicine at Colorado State University, says a newborn calf’s temperature is about 103° F. It drops to a “normal” of 101.5-102° within a few hours. Informa PLC's registered office is 5 Howick Place, London SW1P 1WG. If calves fail to receive proper nutrition, they deplete their brown-fat reserves in 1-6 days and are starving,” Callan says.Protein and energy are crucial, and supplying supplemental fat to cows during late gestation will help calves be better prepared to handle cold weather, he adds.

This, combined with cold stress, can put calves at risk.https://www.beefmagazine.com/sites/all/themes/penton_subtheme_beefmagazine/images/logos/footer.png Cows with adequate protein levels also produce better colostrum.Timely ingestion of colostrum is a big factor in handling cold weather.
“Many ranchers stick a finger in a calf’s mouth to see how cold he is [if he hasn’t nursed, the inside of his mouth is cold], but I encourage use of a rectal thermometer. Registered in England and Wales. A calf that nurses soon after birth stays warmer.“There’s much more to colostrum than antibodies. Moving animals inside to dry bedding and heat lamps are ways to warm up cold-stressed calves. Frost bite, freezing to death and hypothermia are common causes of death of young animals from the cold. Cows deficient in energy and protein may give birth to weak calves that don’t have much reserve, and those cows’ colostrum has less energy and fewer antibodies,” Callan says. This, combined with cold stress, can put calves at risk. If calves are born in cold, windy weather, their temperature drops faster.You can tell when calves are really cold, and you can usually tell when calves will be alright, but borderline calves can be hard to evaluate, says Russ Daly, South Dakota State University Extension DVM. “A small ceramic electric heater in a small, enclosed crate – where you can regulate temperature – works well. It’s often better to sacrifice some old hay than feed it to cows. You need good ventilation, and some way to remove humidity. When the calf is warm and the situation has stabilised, move it back to its mother. If it’s too humid, you’ll have problems with respiratory diseases as well as buildup of pathogens.”Frozen feet are crucial.
