What percentage of your cows seem to calve at night? I learned something today, while talking with my contact in Mexico, and it gotg me wandering abgout something. I was tralking to him about other things,m when I decided to ask If they had a lot of problem with the Mexican Black Vultures. I told him people around here have claimed they actually kill cows and/or calves during birth. He said no, because their native cattle on the range calves at night, He said by the time it is daylight, the calves are up and running and can keep up with momma, and momma has totally recovered by then, to defend her calf. So, they have never had any predation by the vultures. He figures it is an adaptation that has evolved over the 500 plus years they have been there. ..calving only at night. Horses if left alone in the pasture, do this, too. Thinking back the past 30 years or so, we never have seen our Kudzu-Corr calves give birth. Sometimes, we have moved them back by Feb 1st, and still hunted there til mid Feb when the seasons end. I have seen new calves when we do this..most times we ride out at daylight...but none were wet like they were just born. They are up playing around their mommas. Do any of you have cows that always calve at night?
