Maximize performance for extended grazing or feeding periods. Encore® (estradiol) implants are sustained-release estrogen cattle implants that are an ideal fit for lightweight steer calves and long-fed Holstein steer programs. Encore offers a long-acting, convenient implant option.

  • Sustained growth and weight gain: Encore improves weight gain and feed efficiency with no impact on quality grade, even if calves are exposed to heat stress during the early growth stages.1
  • Long lasting: Encore lasts the entire feeding period up to 400 days.
  • Improved efficiency: Because only one implant is required, fewer times through the chute means less potential injury, lower labor costs, less disturbance of normal feeding behavior and lower stress.1

Packaging Sizes: Each box contains 100 doses.
Dosage: Administer one dose in the ear subcutaneously according to label directions.
