SYNOVEX^® ONE GRASS

Gain weight and operational flexibility from 200 days of uninterrupted growth.

Administering SYNOVEX^® ONE GRASS to stocker steers and heifers is proven to increase gain and help stretch out performance when forage is still available for grazing beyond 140 days, which provides marketing flexibility not available with shorter-duration implants. In research studies, stocker calves implanted with SYNOVEX ONE GRASS saw the following performance improvements:

Steers receiving SYNOVEX ONE GRASS implant had a 17.2% improvement in gain over nonimplanted steers.¹
Heifers receiving SYNOVEX ONE GRASS achieved an 11.3% increase in average daily gain.¹

SYNOVEX ONE GRASS 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 features a one-of-a-kind retractable needle for consistent, accurate placement of the implant.

Administration With the SX10 Precision Applicator

SYNOVEX ONE GRASS 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 SX10 features a retractable needle to prevent crushed, bunched or dropped implants, helping you get the most from your implant investment.

To administer SYNOVEX ONE GRASS 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 GRASS 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.
