Merck Animal Health has expanded its cattle implant range in the US after receiving marketing authorization for Revalor-XR.

The product is now approved for over-the-counter sale. Revalor-XR (trenbolone acetate and estradiol) is an extended-release and delayed-release subcutaneous implant for beef steers and heifers fed in confinement for slaughter.

The product is indicated for increased rate of weight gain and improved feed efficiency during 70-200 days after implantation.

Implants are small pellets containing a growth stimulant that is slowly released over a period of time. One Revalor-XR implant (10 pellets) contains 200mg of trenbolone acetate and 20mg of estradiol. Each pellet contains 20mg trenbolone acetate and 2mg estradiol in a polymer coating.

Merck's implant range also features seven other Revalor products containing trenbolone acetate and estradiol.

Other brands of cattle implants include: Zoetis' Synovex; Elanco's Encore and Compudose; and Merck's Ralgro.
