This is the time of year when many folks are choosing their replacement heifers. These tips from Nebraska Extension Beef Educator Aaron Berger and his colleagues at the University of Nebraska-Lincoln (UNL) will help you make good choices. First, get rid of heifers whose mothers were troublesome. Send on heifers that are: • from cows that had difficulty calving • from mothers that had difficulty nursing their calves • exceptionally small at weaning • from cows that are nervous or have an attitude problem Getting rid of these heifers will reduce calving and herding problems and keep you safer. Next, look at birth dates and the age of the cow. Heifers born early in the calving season are more likely to be breed back successfully because they are more mature when breeding season arrives. Rick Funston and his colleagues looked at the “Effect of Calving Period on Heifer Progeny," and found that heifers born in the first 21 days of the calving season had an average pregnancy rate of 90% as yearlings. That dropped to 86% for heifers in the second 21-day period, and was down to 78% for heifers born in the third 21-day period. This success rate continued in the second breeding season with rates of 93%, 90% and 84% respectively base on the same time periods. UNL researchers also found that heifer calves born to cows that were three-years-old or older
