70 something year old vet we consult said flies play into the equation on tetanus.   We’ve gone to banding them as feeders.  We sell most of our feeders so they’re going through the chute anyway.  Wrong or wrong I’m under the belief that they gain a bit better as bulls so might as well capitalize on that a bit till a month or so before they leave as big feeders.  If one or two get a bit big on us and get the bullish look we finish them and they leave as freezer beef.
