For fall calving cows, the calving season is in full swing. Check cows frequently. Identify calves and commercial males should be castrated and implanted.
Obtain yearling measurements (weight, hip height, scrotal circumference) on replacement animals—especially for registered ones. The largest measurements for weight, height and pelvic areas aren’t what you are looking for. In most cases, you are more concerned with minimums, like eliminating heifers with very small pelvic areas so that you minimize their likelihood of calving difficulty.
