Had a couple of different people mention recently that they didn't like to run cattle in large herds (3-400) because bull injuries due to fighting were greater. Is 3 bulls in 3 separate 100 cow herd's gonna be different than 10 bulls in a 300 cow herd? Thinking this is an old wives tale. Currently running 10 bulls in a 300 cow herd.
Until me and Scott lost our minds last year, and expanded our herd to 700, for years we had between 100 and 120 Corriente cows. We'd put in either 5 or 6 bulls about Easter, and get them out Memorial Day. We calved in February each year. Never had any bulls injure each other, but these bulls are all pastured together most of the year when not working, so that may have played a part.
Right now, because the man we are contracting the calves to wants a year round supply, we have only 6 bulls on those 700, which are in 3 different pastures. When buying up 600 more throughout the year last year, we bought cows from open to 9 mos pregnant, to some with 1- 6 month old calves on them, and these bulls stay in year round.
Back when we had good sense, we'd round them up in March to tag and band, then round them up again Labor Day to trailer wean them carrying them to the next sale day. Now it is banding and tagging this month's calves and weaning the 6 month olds, at the end of every month.
I bet you have a pretty tight calving period, with 10 bulls on 300 cows, don't you?
