[QUOTE="lithuanian farmer, post: 1798846, member: 19683"] Most here know our system more or less. But wanted to add some stuff. An easy calving bull is considered to be under 90lbs here. Not talking about my opinion alone. It's a pretty standart view here overall. Would be nearly impossible to find a farm, where all calves would be under 70lbs. An overall average would be around 80-100lbs, depending from the farm and breed. Know some Angus breeders where many calves go over 100lbs, some over 110lbs. To answer some general questions- those cows, which always have small calves at birth usually don't stay here for long. The main reason is that their calves are lighter at the weaning. No difference in conception between them and those which have 100lbs calves. Those, which had calves over 110-120lbs most of the time return back in calf on time. Except if they had some serious issues, like metritis, retained placenta, but it can happen for cows with small calves too. Our cows start showing age at around 12-13 years. Rarely younger. Some could live even longer, but needs to have a spot for heifers, so the oldest cows are the first ones to go most of the time. About calf vigour: 100lbs calf is as bright as the smaller ones. Some issues start appearing when bw is at 100lbs and over. Not always, but it happens. Also another issue, which is actually more common with big newborns than lazy, stubborn calf, is them not being able to hold their weight on their legs. Especially if calf has small bones, but plenty of muscles at birth. The calf can be as bright as possible, want to suck 5min after birth, but find it hard to lift his weight for the first day. If there are any other questions about big calves feel free to ask. If I could I wouldn't choose anything under or over 85-110lbs range. But I'd rather prefer a bigger calf than a teeny tiny one.
