One hundred twenty-seven suckling calves were allotted to one of
three treatments:
(1) Control group - not implanted
(2) Implanted (Ralgro) once during sucking period
(3) Implanted (Ralgro) twice during sucking period - at average
age of 44 days and 70 days later
Using one Ralgro implant improved the weight at weaning by 8.4 pounds,
while re-implanting, thus utilizing two implants during the suckling
phase, resulted in an extra 43.0 pounds.
