Understanding Pregnancy Diagnosis in Beef Cattle

examples of ultrasound imagesBecause 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.

nsion Calendar 2002-September-Campuswide Engagement--Cattle, cow, agriculture, poppies, flowers, spring. Photo by Eric ZamoraIt is estimated that in Florida alone the cost of infertility of beef cows exceeds $86 million annually. Infertility occurs when cows become pregnant but fail to calve, become pregnant late in the breeding season and fall out of the annual production cycle or fail to become pregnant during the breeding season. The latter two causes of infertility are a direct result of the length of the post-partum interval. This 4-page fact sheet was written by Kalyn Bischoff, Vitor Mercadante, and G. Cliff Lamb, and published by the UF Department of Animal Science, March 2012.

AN208 What is the Economic Impact of Infertility in Beef Cattle?

AN208, a 3-page fact sheet by G. Cliff Lamb, Carl Dahlen, and Mary Maddox, describes the problem of infertility, how cattle producers can calculate the impact on their own operations, factors that contribute to infertility, and total cost to Florida beef producers. Includes references. Published by the UF Department of Animal Sciences, August 2008.
