To all there is an appointed time, even a time for every purpose under the heavens: a time to be born, and a time to die; a time to plant, and a time to pull up what is planted; a time to kill, and a time to heal; a time to tear down, and a time to build up; a time to weep, and a time to laugh; a time to mourn, and a time to dance; a time to throw away stones, and a time to gather stones; a time to embrace, and a time to refrain from embracing; a time to seek, and a time to let wander away; a time to keep, and a time to throw away; a time to tear, and a time to sew together; a time to keep silence, and a time to speak; a time to love, and a time to hate; a time of war, and a time of peace. Ecclesiastes 3:1-8 (Hebraic Roots Bible)
For the past several years, my cows have been bred to calve 15 April to 30 May. Though that is earlier than i prefer, it was a decision i made some 8 years ago because i was having up to 30% death loss in baby calves getting scours. Scours so bad that sometimes the calves would die before they even passed that first scouring poop! That was calving 15 May to 30 June. So after a great deal of research into the possibilities, i made the decision to push it back. And that made all the difference – not one single case of scours since that time.
Now, i did sell those cows which lost their calves, so that is likely a good part in the reason there are no longer any cases of scours, yet it’s not the full explanation. Corriente cows tend to have rich milk, which, combined with the heat caused by grazing toxic fescue and the outside air temperature may cause additional stress on baby calves.
However, today’s weather is a reminder of why April is too early in north central Missouri to start the calving. Although my calving season officially starts 15 April, there have already been 6 calves born – fortunately, the weather has been decent until today and it is pouring down cold rain, muddy conditions, temperature at 46F (wind chill 40F) and a stiff 14 mph NNW winter type wind. Very hard are on young and newborn calves.
So, yesterday, after hearing once again from Jaime Elizondo (others have advised as well and i know better), i plan to wait to turn in the bulls 23 July for 45 days. It is with trepidation that i make this change when, despite crappy April weather these past several years, i’ve not lost any baby calves.
Here is to change once again. On the other end of it, it’s always a problem to wean calves the first week of March when grass is yet so far away and there is bitter weather ahead of them. Calving later will allow me to wait another 2-3 weeks before weaning the following year and the cows will have better weather in which to regain good condition. However, leaving the bulls in a couple more weeks is the only way to avoid me being in ragweed season to remove them. (many of my decisions revolve around ragweed season due to me being incapacitated during that time)
So, what have i decided going forward? To completely avoid ragweed season, I plan to turn out the bulls about August 4 and pull them back out about 45 days later which is September 19. Hope it works!!!
