Effects of zeranol on skeletal growth of cull cows and heifers (a note)

  • Author(s) / Creator(s)
  • Thirty-two cull cows aged from 1 to 13 yr were allocated to five age groups and fed individually for 82 days, then slaughtered. Half of the cows within each group were implanted with 36 mg of zeranol. Zeranol had no significant effect on average daily gain, feed efficiency or backfat thickness, but caused a decrease in radio-ulna mass (P = 0.10) and length (P = 0.03). Rate of bone growth at the distal end of the radio-ulna decreased with increasing age to 0 at 4–5 yr.
