Tally Time: Get More Value from Pregnancy Diagnosis
We just finished preg checking some replacement heifers from a project conducted earlier this spring. The heifers were all artificially inseminated (AI) at a single fixed-time. Natural service sires were turned in 10 days after AI and removed 20 days later. This short breeding season was used for a number of reasons but most importantly so that there would be no late calving replacement females.
