[QUOTE="KNERSIE, post: 593736, member: 4353"] The ratio we use for multiple sire herds is 3 bulls for every 100 cows. The spread in age is equally important, one mature, one 2 or or 3 year old an one yearling. Typically most herds just add a yearling every year and sell the oldest bull. In such a breeding system expect the mature bull to sire the bulk of the calves (about 60) the two year old about 30 and the yearling about 10. The pecking order should be established well in advance so that they don't have to sort that out first when the first cow comes in season. Bored bulls also tend to fight more, so depending on the length of the breeding season its usually good practice to reduce the number of bulls after the first 28 days or so. It is also believed that bulls should also be turned out in unequal numbers, if two fights the third one gets a chance to breed, etc. How much this is the case in reality I don't know, from my experience once they start fighting everyone joins in.
