The next week will be busy at the Dickinson Research Extension Center. The cows have been turned out on cool-season grass and the yearlings need to be worked.
The yearling steers are vaccinated and have been turned out for summer grazing or sent to the feedlot. The center typically sends half the yearling steers to grass and the other half directly to the feedlot.
The yearling heifers also need to be processed, the replacements sorted off and the remaining heifers spayed and sent to grass. Replacements basically are preselected because the breed type is monitored and fit into the center’s crossbreeding program.
Historically, the center would prefer to mate a different breed of bull to a crossbred cow. The industry calls that crossbreeding, and the center looks to achieve maximum hybrid vigor in the cow and the calf by utilizing different breed types in the sires that are used.
Those heifers that are not in the replacement program are vaccinated, spayed and sent to grass along with the steers. Last year was the first year the center spayed heifers and the heifers did well. By the time the heifers were harvested, 71.6 percent of the heifers graded upper choice or prime, with 97.5 percent of the heifers having a yield grade of 3 or lower.
The center had zero death losses, and the average daily gain in the feedlot was 3.56 pounds per day, with a 6.27 dry-matter feed conversion.
After feedlot costs, the heifers returned to the ranch, on average, $1,454 per head. The heifers did well, and producers should not hesitate to contact their local veterinarian to explore the concept of spaying extra heifers. The challenge of running open heifers on grass with all the neighborhood bulls possibly getting loose is frustrating.
Because the heifers are spayed, the heifers are more content and focus on grazing and gaining weight. Last year’s heifers gained about 2 pounds a day on grass, and the expectation would be similar for this year. There certainly is a good feeling when the winter pens or paddocks are empty and the cattle are on grass.
There is that subtle thought and peace of mind once the stock are unloaded and settle into their grazing routine. However, don’t dream too long because this is a good time to reflect on last year’s calving season.
Just how many of those calves did you turn out to pasture? Not to bring up the tough times, but not long ago, the cows were calving, the temperature was cold and the mud was deep. Experience would say that you do not want to ask managers how calving went because the response would be less than objective as they reflect on the bone-chilling cold and not getting enough sleep.
