Summary
Flank spaying of intact yearling heifers has been a routine procedure for ranchers for several years. Most recently a new technique called rumen autografting has created a lot of interest with ranchers. The technique involves implanting or grafting a small piece of ovarian tissue into the outside lining of the rumen wall. A trial was initiated on May 14, 1986, to compare summer grazing performance of intact flank spayed and rumen autografted heifers with and without a growth implant. The 231 crossbred heifers were randomly allotted to the trial and grazed together for 99 days as one herd. The results indicate the greatest increase in growth rate (19 lb additional) was due to the implant effect. Autografted heifers tended to gain slightly more than their counterparts. but the difference was not significant. This work supports other research which indicates that the benefits of rumen autografting are not substantiated.
