SYNOVEX^® ONE FEEDLOT

Give feedlot steers and heifers up to 200 days of increased weight gain and improved feed efficiency.

Administering SYNOVEX^® ONE FEEDLOT to feedlot steers and heifers is proven to boost gain and enhance feed efficiency for up to 200 days, delivering an exceptional return on investment. Compared with nonimplanted feeder cattle:

Steers implanted with SYNOVEX ONE FEEDLOT saw a 15.4% improvement in average daily gain (ADG) and gained 3.45 lb./day.¹
Feed efficiency in steers improved by 9.8%.¹
Heifers implanted with SYNOVEX ONE FEEDLOT had a 12% increase in ADG, gained 3.09 lb./day and improved feed efficiency by 7%.¹
Research has shown SYNOVEX ONE FEEDLOT delivers ADG consistent with the performance of Revalor^®-XS.²
SYNOVEX ONE FEEDLOT is convenient — it does not require refrigeration before use and is administered with the same SX10 Precision Applicator used with all SYNOVEX formulations. The SX10 applicator features a one-of-a-kind retractable needle for consistent, accurate placement of the implant.

Key Features and Benefits
Proven Efficacy in Feedlot Steers

SYNOVEX ONE FEEDLOT has undergone several trials to demonstrate its long-active efficacy in feedlot steers. Steers implanted see:

Consistent daily weight gain¹— ADG over 161- and 200-day feeding periods was comparable for steers administered SYNOVEX ONE FEEDLOT, REVALOR-XS and SYNOVEX PLUS^®.

Demonstrated feed efficiency¹ — Gain efficiency (G:F) and feed efficiency (F:G) over 161- and 200-day feeding periods was similar for steers administered SYNOVEX ONE FEEDLOT, REVALOR-XS and SYNOVEX PLUS.³

An extended-duration formulation tailored to feedlot steers and heifers

Delivers the proven 10:1 ratio of TBA:E2 (200 mg of testosterone, 28 mg of estradiol benzoate equivalent to 20 mg of E2) with a patented polymer barrier that extends the formulation payout up to 200 days³

Administration With the SX10 Precision Applicator

SYNOVEX ONE FEEDLOT is easy to administer with the SX10 Precision Applicator, which features a one-of-a-kind retractable needle for consistent, accurate placement of the implant.^† The SX10 is used for all SYNOVEX implants — no need for multiple applicators for different implant potencies. The retractable needle prevents crushed, bunched or dropped implants, helping producers get the most from their implant investment.

To administer SYNOVEX ONE FEEDLOT with the SX10 applicator, follow the instructions included with the applicator for loading the implant clip, cocking the applicator, disinfecting and cleaning, replacing the needle, and removing the implant clip.

English and Spanish training videos are conveniently available online to help educate feedlot employees on implanting techniques, sanitation and use of the SX10 applicator.

^†All SYNOVEX formulations are compatible with both the SX10 and metal revolver applicators.

Implant Quality (IQ) Program
The Implant Quality (IQ) program from Zoetis helps you get the most out of your SYNOVEX ONE FEEDLOT implant. It provides:

Establishment of implanting goals

Development of a customized quality assurance (QA) program to fit the operation’s goals

Training of crew members in correct sanitation and implanting techniques

Monitoring and analysis of results

The program includes several useful tools:

Sanitation gear, including a disinfecting tray, sponge and ear brush, to help clean the ear prior to implanting

Service reports to assess implanting techniques of the processing crew and to check animals for implant retention three to four weeks later (available in paper or electronic formats)

Certificates of completion for all members of the processing crew

Ask your local Zoetis representative how to get started with the IQ program.
