I've seen guys that dock them and they don't have a decent fly program...............personally I find it barbaric to dock them as heifers and before they are in the milking string where you SHOULD have some fly control.
I always said that there were 3 degrees of swatting in my barn.............the first was "mildly annoying" and I could live with that. The second was PITA, and tho it was borderline, I could mostly live with that too. The 3rd was "downright vicious" and that's when they got docked. I told the SU if he didn't like it, HE could milk them. We did find that those with docked tails acquired the nasty habit of slinging their silage over their backs at the bunk. Did yours?
When is the sale? Soon, if I remember correctly. Will you have an auction on the farm or take them to an auction barn? Doing anything special to "pretty them up?" We had a guy come in a week before and clip, then the day before to wash them all. It was the best $1500.00 we spent in sale prep. It paid for itself several times over. We just did that to the milking cows, not to any of the young stock and bred heifers. They were all pretty clean. Our sale was Oct. 1st, 2010.
