CowCop, can you tell us more details about this situation? Again, thank you for posting the pictures!
Will try to answer your questions:
1. The 2 hoof coverings were found within 9 inches of the calf, kind of smushed into the dirt.
2. This was the very first calf to be born last year--- 7-10 days before the next calf.
3. My boss had used a new bull and when I saw this "first calf" I was a bit unnerved that we possibly had a sick bull and was anxious about the next calves being born.
4. From my notes---This calf didn't look developed in the head area.
5. This calf was discovered by the hay rack--which is 80 feet long by 8 foot wide. The other cows were away from it, but watching.
6. From what I could determine, the calf never got up to nurse.
Your theory that it may have been dropped from a standing cow, is a good one.
Other thoughts: You have mentioned the lack of a worming program by the owner of these cattle in the past, which leads me to believe there may have been several other poor decisions on his part in the area of nutrition, mineral, vaccinations, etc. that may have an effect on these calves.
Good memory greenwillow.
7. This group had NOT been wormed and have never been vaccinated.
They are however on lush pasture all summer and enjoy the best hay in the county--24/7- all winter. They have hay in front of them every minute of the day. The main herd is never grained.
I am still fighting a battle for him to put out enough loose salt & mineral for the entire herd, in the winter.
I think thats all your questions--let me know what else you would like to know. I will do my best.
Unfortunately, I do have alot of photos of various calf and cow issues.
I tend to "police" alot of different cows and herds.
