Why is there a calf in the bathtub!?
This winter has proven to be colder and bringing more snow than ever in the Northeast. The old timers around here are saying it is more like the way winters used to be “back in the day”. Personally, I do not ever remember the extreme cold being this bad from a length of time perspective. Everyone expects it to be “cold” during the winter, but -20 to -30 wind chills day after day in Pennsylvania were unheard of until this past February.
Unfortunately today is the first day of spring and someone forgot to tell Mother Nature. Here in the “Twin Tiers” of PA & NY we’re getting what will hopefully be the last spanking of snow for this year! It’s been snowing pretty steady since day-break and doesn’t show any signs of stopping or even slowing down until after dark tonight. Normally this is something that is expected around here in March, sometimes it’s even happened up until the end of April!
The biggest problem with this type of weather is when it merges with the beginning of calving season for most producers who don’t calve with nature. When you don’t follow the breeding and birthing of native wild animals in your neck of the woods, you are always going to run the risk of calf loss due to “exposure”. Meaning unfavorable weather conditions like SNOW and below freezing temperatures. Folks, there is a reason that deer, bear, and just about every other mammal won’t give birth until it is truly Spring! Why have producers changed this natural process? Money. That’s why, Money. And it’s at the expense of the newborn and momma’s.
If you are stuck in the “anytime” rut of breeding your animals, here are some way’s to possibly save an animal born on snowy or frozen ground out of its “Natural” season.
Re-warming Methods for Severely Cold-stressed Newborn Calves
Several years ago, an Oklahoma rancher told of the success he had noticed in using a warm water bath to revive new born calves that had been severely cold stressed. A quick check of the scientific data on that subject bears out his observation.
Canadian animal scientists compared methods of reviving hypothermic or cold stressed baby calves. Heat production and rectal temperature were measured in 19 newborn calves during hypothermia (cold stress) and recovery when four different means of assistance were provided. Hypothermia of 86 degrees F. rectal temperature was induced by immersion in cold water. Calves were re-warmed in a 68 to 77 degrees F. air environment where thermal assistance was provided by added thermal insulation or by supplemental heat from infrared lamps. Other calves were re-warmed by immersion in warm water (100 degrees F.), with or without a 40cc drench of 20% ethanol in water. Normal rectal temperatures before cold stress were 103 degrees F.
The time required to regain normal body temperature from a rectal temperature of 86 degrees F. was longer for calves with added insulation and those exposed to heat lamps than for the calves in the warm water and warm water plus ethanol treatments (90 and 92 vs 59 and 63, respectively). During recovery, the calves re-warmed with the added insulation and heat lamps produced more heat metabolically than the calves re-warmed in warm water. This represents energy that is lost from the calf’s body that cannot be utilized for other important biological processes. Total heat production (energy lost) during recovery was nearly twice as great for the calves with added insulation, exposed to the heat lamps than for calves in warm water and in warm water plus an oral drench of ethanol, respectively. By immersion of hypothermic calves in warm (100 degrees F) water, normal body temperature was regained most rapidly and with minimal metabolic effort. No advantage was evident from oral administration of ethanol. (Source: Robinson and Young. Univ. of Alberta. J. Anim. Sci., 1988.)
When immersing these baby calves, do not forget to support the head above the water to avoid drowning the calf that you are trying to save. Also it is important to dry the hair coat before the calf is returned to cold winter air. If the calf does not nurse the cow within the first few hours of life (6 or less), then tube feeding of a colostrum replacer will be necessary to allow the calf to achieve passive immunity by consuming the immunoglobulins in the colostrum replacer.
Obviously not every calf born in cold weather needs the warm water bath. However, this is apparently a method that can save a few severely stressed calves that would not survive if more conventional re-warming methods are used.
I hope this information is helpful to all producers since winter weather is not just above the Mason-Dixon line anymore! This winter has showed us what we are in for in coming winters even in Texas and Kentucky. I’m not expecting my wife to allow me to do it, but luckily so far, we haven’t had to give our calves a bath, in a tub, in the house.
