It seems that this years calf from our oldest cow (12 years old) just doesn't have the growth andc"pop" that her previous calves have had. Also it appears that somewhere in her 4th month she must have slipped her calf. She was in standing heat last week. She's alwasy settled first service, as she did this year, and has never had a problem before. This is her first bull calf so maybe that's the reason this one isn't as impressive. The thought that I have had is that possbily she's getting to the age that she is dipping into poor quality and low vitality eggs. We're working them tomorrow so we'll know for sure if she is open or not, but it's a thought that I've had and was curious if anyone has noticed older cows having poorer calves then she has traditionally had.
