MGA®

(melengestrol acetate) Medicated Feed Additive

United StatesUnited States

Time Tested and Industry Trusted

The stress of estrus can minimize intake, increase aggressive behavior and make heifers vulnerable to injury, affecting carcass quality. MGA is the go-to feed additive for suppressing heat in feedlot heifers, resulting in improved feed efficiency, increased weight gain and improved quality grade.*

THE MGA ADVANTAGE

  • Suppresses estrus to reduce energy loss, improves feed conversion and weight gain and maximizes overall profitability in heifers of any breed.
  • Suppresses heat cycles, decreasing riding/mounting (bulling) behavior and improving overall animal well‑being.
  • Reduces dark cutters and improves meat quality, delivering more uniform high-value carcasses.

INDICATIONS

  • For increased rate of weight gain, improved feed efficiency and suppression of estrus (heat) in growing beef heifers fed in confinement for slaughter.
  • For suppression of estrus (heat) in replacement beef and dairy heifers.

Beef and dairy

HOW IT WORKS

The production-efficiency benefits of MGA include the suppression of the adverse effects associated with recurrent estrous activity (mounting of heifers in heat and reduced feed intake during the estrus event). As an orally active synthetic form of progesterone (progestogen), MGA suppresses ovulation by suppressing the luteinizing hormone (LH) pulse frequency. Additionally, the large follicles that develop from this action can release increased levels of the growth hormone and estradiol, leading to improved feed conversion rates and average daily gains.
