Young dairy calves are particularly susceptible to hypothermia because of poor insulation and high surface area to volume ratio. Tessa Markovich, BVSc, MS, Dipl. ABVP, Te Puke Veterinary Centre, Te Puke, New Zealand, says on grazing dairies, calf hypothermia can be a big problem in those herds with early-spring calving. She adds that small crossbred or Jersey calves tend to tolerate the cold less than Friesian calves.
Traditionally in temperature climates it is possible to collect calves once or twice daily from the calving paddock, Markovich told attendees at the 2012 Western Veterinary Conference this week. “If calving occurs during periods of inclement weather more regular collection (hourly) of newborns is critical to their survival.”

There are five “Qs” of colostrum management: quality, quantity, quickly, sQueeky clean, quantify passive transfer, says Sam Leadley, PhD, Attica Veterinary Associates, P.C., Attica, N.Y.
But often when there is a “surge” of calvings on a dairy, colostrum shortcuts happen in colostrum management. Where do the shortcuts happen that negatively impact calf health? Leadley says at every point.
