I generally do not like twins at all. Theyalways seem to have problems. one small weak one and one agressive one or one is backwards and dead or the good one gets all twisted up and dies and you are left with the runt, or it is from the poorest milker in the herd and both calves turn out to be runts. But, that said, this year we have a set of twins, from a 7 year old shorthorn cow with tons of milk and they are both doing very well. However, the set is one of each. The bull calf was 108 pounds and the heifer was 100 pounds. They are possibly two of the best calves that we have at his time. The sire of the twins was not a twin, but came from a cow that has twins every other year. Last year she had her third set of twins, and they were just what I expect from twins, all twisted up and dead. Give me one good calf and I am happy.
