PPRM- I do about the same thing on picking replacements....Thats where the little pocket book comes in handy-- start from when the calf is born keeping notes on BW- calving ease- cows udder- cows milk supply- cows disposition- build- any faults I notice...Keep adding to it thru the summer and compare back to bloodline history and by fall its pretty easy just to make out a list of the tag numbers you want to keep for replacements...

Sure wish I would have kept more the last couple of years now- some of these old gals are dragging out calving.....
