Stocker cattle benefit from re-implanting and ionophores
Stocker cattle will gain an extra 20 to 25 lbs if re-implanted in mid summer. Producers should use the same implant as previously given or another implant for that weight and sex of cattle. Ionophores can also benefit grazing stockers. Products like GainPro® or Rumensin® are approved for grazing cattle and can result in increased gain of 10 to 15%. Remember that response to implants and especially ionophores require abundant good quality pasture. Results with these products after July may be disappointing if you are grazing over-mature grasses or have limited grazing available.
