Not all bulls are herd bulls

Most bulls can fill feedlot pens, but some are herd bulls and some are neither. Every year, the competition in the bull pen gets tougher, so some bulls need to leave.

At the Dickinson Research Extension Center, seven long, yearling bulls needed to leave. They were neutered and weighed in at 1,179 pounds after a summer on grass. Last fall, they were sent to the feedlot and weighed 1,636 pounds after 88 days on feed. They gained 5.2 pounds per day and had a dry feed conversion of 5.3 pounds.

The point is that there are opportunities for the excess bulls other than a long winter in the bullpen. Neutering and feeding those excess yearling bulls is a viable option. As cow numbers dip, so should bull numbers. The only purpose a bull has is to breed cows so they will conceive calves. With fewer cows, fewer bulls are needed.

Although not a highly technical study, the other day I was looking at the sale ads and could not help but note the number of bulls listed. There would be no problem finding a bull because many seedstock producers still are selling. Granted, most bull sales are over, but private treaty sales are plentiful.

In addition, a fair number of 2-year-old bulls were listed. Two-year-old bulls are not uncommon but may not be the bull of choice for most seedstock producers to market because the additional 12 months of expense needs to be subtracted from the sale price.

Sometimes the market may justify the extra year. However, quick comparisons of the average 2-year-old bull value versus the yearling are seldom exciting. And what does one do with a 2-year-old bull that does not sell?

That being said, the Dickinson Research Extension Center has a good inventory of bulls. Unlike a private producer, as cows are assigned to research pastures, the number of cows in each pasture are small. However, every pasture needs a bull, so that is why the center has a larger bull inventory.

We still haven’t answered the question about what to do with the extra bulls. At the center, once everything is allotted for the summer, the extra steers are put on grass. Any unused bulls are neutered and also added to the inventory of steers on grass. In addition, yearling bulls may be neutered once they no longer are needed as breeding bulls. The rationale is that the center wants to minimize the number of bulls that are kept through the winter.

How did these bulls do from start to finish? This past year, the center ended up with 27 steers on grass. Seventeen of those were neutered bulls. Following the summer on grass, all 27 head were shipped to the feedlot in late October. READ MORE
