Title: Effect of Ralgro on Nursing Calves
Author: Dunn, Barry H.
Description: In 1976 and 1977 nursing steer and heifer calves were implanted with 36 mgs or Ralgro when they weighed approximately 138 Ibs. Average daily gains were calculated for the summer grazing period and weaning weights were adjusted for age and sex of calf and age of dam. Implanted calves gained 6.8% faster during the growing season and were 22.2 lbs heavier at weaning than nonimplantcd calves. Implanting heifer calves did not appear to have any effect on yearling breeding perfomance or in the number of heifers requiring assistance during their rust calving.
