Implants will run from about .95c/dose on Synovex, on up to almost $8.00/dose on Revalor XS. The thing to remember when using an implant, is to start with Low Levels and work your way up, Granted, you can get better gain/growth, using a hotter implant, but you tend to burn the animal up to quickly, and they stall. Worse yet, if you don't keep them through finishing, a feedlot like ours, spends the higher $ for that terminal/ or last 110-130 day implant and get no results. Also, the reduces the grade on a lot of the animals.
If you would like a simple implant program try this,
550# or less-Ralgro
550-750# Synovex S or H
750# and up (depends a little on what the cattle look like, or how hard you are pushing them, but
Synovex Choice or Plus (when available) makes a nice finishing implant.
Yes, Implant guns are free, and so are the nice Implant trays for disinfecting the needle if you know where to go.
Currently there is a nationwide shortage on implants, and all but the Ralgro, Revalor XS, Revalor 200, Compudose and Encore are almost impossible to find. Looks like the shortage may last through the fall and into early spring.
