Young cows need extra nutrition during breeding season
First and second calf heifers are still growing as well as lactating during the breeding season. These heifers will need about the same total amount of energy as a mature cow, but they eat about 15-20% less feed. So these young cows need 4 to 5 lbs of corn, corn gluten or barley daily to meet their extra energy needs and breed back quickly. (JBH)

Stocker cattle benefit from reimplanting and ionophores
Stocker cattle will gain an extra 20 to 25 lbs if reimplanted 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 overmature grasses or have limited grazing available. (JBH)
