Manufacturer: Intervet/Merck Animal Health

(trenbolone acetate and estradiol)

NADA # 140-992, Approved by FDA

For Steers and Heifers Fed In Confinement For Slaughter

Description

Revalor®-200 (trenbolone acetate, CAS Registry Number 10161-34-9, and estradiol, CAS Registry Number 50-28-2) is an implant containing 200 mg of trenbolone acetate and 20 mg estradiol. Each implant consists of 10 small yellow pellets. Ten implants are provided in a cartridge.

Manufactured by a non-sterilizing process.

Restricted Drug (California) - use only as directed.

Revalor-200 Indications For Use

This product contains trenbolone acetate and estradiol in a slow-release delivery system which increases rate of weight gain and improves feed efficiency in steers and heifers fed in confinement for slaughter.

Do not use in veal calves. Effectiveness and animal safety in veal calves have not been established.

Note

Revalor®-200 is not better for increased average daily gain or improved feed efficiency than Revalor®-H (140 mg trenbolone acetate/14 mg estradiol) in heifers fed in confinement for slaughter.

Studies have demonstrated that the administration of Revalor®-200 can result in decreased marbling scores when compared to non-implanted steers and heifers.

Dosage

One implant containing 200 mg trenbolone acetate and 20 mg estradiol is administered to each animal. The 10 pellets which make up the dosage of Revalor®-200 are contained in one division of the multiple dose cartridge. Ten doses are in each cartridge. The cartridge is designed to be used with a special implant gun.

Route Of Administration

The implant is placed under the skin on the posterior aspect of the ear by means of a special implanter available from Intervet Inc.

With the animal suitably restrained, the skin on the outer surface of the ear should be cleaned. The implant is then administered by the method shown in the diagram below.

Site Of Implantation

After appropriately restraining the animal to allow access to the ear, cleanse the skin at the implant needle puncture site. It is subcutaneous between the skin and cartilage on the back side of the ear and below the midline of the ear. The implant must not be placed closer to the head than the edge of the cartilage ring farthest from the head. The location of insertion of the needle is a point toward the tip of the ear and at least a needle length away from the intended deposition site. Care should be taken to avoid injuring the major blood vessels or cartilage of the ear.

METHOD OF USE

1. Do not remove the cap of the cartridge containing the implants.

2. Place the cartridge (D) (with the capped end to the front) into slot at the top of the implanter magazine (marked A on the diagram).

3. Gently push the cartridge into the slot until it clicks into place.

4. The implanter is then ready for use.

5. Take the ear of the animal firmly with the free hand (in the manner shown in Fig. 1). Then insert the needle into the subcutaneous tissue at the point indicated (in Fig. 2).

6. After inserting the needle to its full extent, squeeze the trigger (E) gradually. Allow the pellets of the implant to be deposited in a single row.

7. Withdraw the implanter. This will advance the cartridge one groove in the magazine and the next implant is now ready for use.

8. When all the implants have been administered, the cartridge will fall out of the bottom of the magazine and may be replaced by a new one.

9. To change the needle, loosen the needle locking nut (labeled F in Fig. 3) and replace the needle. Tighten the nut finger tight and the implanter is ready for use.
