EPD is expected progeny difference.
Not GUARANTEED PROGENY DIFFERENCE,
Exactly! And the cow puts 50% of those genes in there too.
Dad's old Red Angus bull "always" throws nice small calves, you can count on heifers weighing 70-75 lbs and bulls weighting 75-80 lbs. EXCEPT for this one old cow, that old cow always has a calf that's in excess of 100 lbs-- since the bull throws nice uniform calves with all the other cows, the only conclusion is that the COW has a big influence on the size of the calf.
We AI'd Dad's some of mature cows last year to the Red Angus bull Monu, his BW EPD was .6 and his CED was +6. I was warned not to use him on heifers, but I had 1 Red Angus cross heifer, well grown, and 6 months older than most heifers being bred for the first time. The heifer was 21 months, weighed 1000 lbs, and wasn't fat when bred, so I took a chance on using him, knowing that there would be someone around when it came time for her to calve. She calved Feb 27 (4 days past her "due date"), TINY little heifer calf that was up, on it's feet, and nursing in minutes. Mature cows are calving now and the calves are TINY and very alert and lively.
This year the bull's BW EPD is .2, but his CED is +1.
Still waiting on the old cow that always has "monster" calves, it'll be interesting to see what she has with this bull.
