Understanding Pregnancy Diagnosis in Beef Cattle: AN314/AN314, 11/2014

Because 55 to 70 percent of the input costs associated with a beef cattle operation are related to nutrition, culling open (non-pregnant) cows after the breeding season can save as much as $200 per head that can be diverted to the purchase or development of replacement females, sire selection, increased nutritional management, and other management-related costs. Pregnancy diagnosis can be performed simply during vaccination or at the time of weaning. There are three practical methods: rectal palpation, transrectal ultrasonography, or blood test.
