[QUOTE="Ebenezer, post: 1309143, member: 24565"] The OWT developed prior to the MCE EPD so the old wives were not just gossips but were basing off of experiences. I totally agree with Dun that stacking CED is fine if the other EPDs do not dwindle. Also prior to CEM EPDs the term "curve bender" was a rage or fad term. Small calves and great growth. One such was an ABS bull called Pfred. He lived up to the deal and had daughters that matured into the 1700s and sons that sold like hotcakes to commercial cattlemen. The sons were great as terminal sires but the daughters were too big. Where the rub comes in on calving ease bulls are the low growth bulls. Nothing wrong with average growth but if you stack low growth bulls long enough just to have calving ease your cattle herd will diminish into something less than you want them to be. It seems to suck the sap out of them. One thing that EPDs and the sire summaries were good to study was the relative number of bulls from given prefixes (herd) and you could see that the XXX bulls were great CED sires and the great majority carried proven negative numbers on CEM. Red flag for me if the majority of the breeding from that source was pretty consistently negative. From experience, I prefer a proven bull with +CED and +BW. The shape of the calves is superior even if they weigh a little more. And they will grow at a decent rate. [/QUOTE]
