Abstract
A 150-day field study was conducted to evaluate single vs. reimplant strategies for stocker heifers grazing irrigated smooth bromegrass . Three hundred forty-three previously nonimplanted British crossbred heifers averaging 494 lb were assigned to one of seven treatments:
- no implant-control (NC),
- Revalor-G® (REVG),
- Ralgro® (RAL),
- Synovex-H® (SYNH),
- REVG/REVG,
- RAL/RAL, and
- SYNH/SYNH. Reimplanting (Treatments 5, 6 , and 7) was done on day 75 of the trial. In the first 75 days, all implants increased (P<.05) average daily gain (ADG) compared to NC. For the last 75 days (days 75 through 150), heifers implanted with REVG, REVG/REVG, RAL/RAL, and SYNH gained faster (P<.05) than NC or those implanted with RAL, and SYNH/SYNH. No significant differences occur red among the latter three treatments. Over the entire trial, there was no advantage to reimplanting heifers with REVG or RAL. SYNH/ SYNH heifers gained less (P<.05) than their single -implanted counterparts.
