I am sometimes amazed how some cows can cycle as quickly as they can. Last year, I had probably the hardest pull I have ever had, from a mature cow. I am not sure why the calf was so huge as this same cow had two calves in previous years with BWs of 90 and 92 lbs, from the same sire.Maybe it was partly due to our nasty winter, as we have seen bigger BWs in very cold winters before, but this calf was simply a monster. This was a heifer calf that was probably over 140 lbs. The calf died shortly after it was born just from taking too long to be born. I was so played out myself that I did not bother to weigh it seeing it was dead. It was a really hard pull and the calf hip locked and she was tore up considerably. I think it took the cow two hours to get up after she calved... and I think I was close to three hours ... ha ha.
I turned this cow out on a pasture with a group of cows that were running with a bull, as I thought the green grass would be good for her. I never expected she would even re breed and I thought I would probably ship her to market once she recovered. 18 days following this nasty, nasty birth, I was shocked to see her in heat and get bred by the bull. She settled to this service and had a nice heifer calf this year, that was born unassisted with a BW of 88 lbs. Some times Mother Nature can work small miracles!
