Heifer bull means he will throw a smaller calf, for starters. CED is calving ease direct... the higher the number, the MORE LIKELY he will throw a calf that will be smaller, and "easier to calve"... BW is birth weight so a minus means it should be lighter weight than the average calves from a less CED.... in other words, the calves again should be a little smaller. The WW is weaning weight, and YW is yearling weight.... they are decent for an easy calving bull of that high a CED...
Yes, in plain english his calves SHOULD be smaller at birth, the heifers should have very little trouble having them... they will not grow like gangbusters, but should grow decent but will not mash any scales at weaning... the RADG is residual average daily growth (I think that is it) and will not be very fast growing...
BUT you want smaller calves so you are not pulling them... you want the heifers to "spit them out" and the calves to get up and get to nursing without any traumatic birthing problems. If these are your own heifers, part of the calf's growth will come from the milking ability of the heifers themselves....if the dams of the heifers are good milkers, then they will hopefully milk good and the calves will grow better.
If the bull is decent to look at, and you want an easy calving heifer bull, then is not a bad bull to buy. If he were close to me I would go look at him... our 2 easy calving bulls are 10 yrs old now... weigh 1800-2000 lbs maybe and we are still using them... they are easy gentle breeders and have not had an injured heifer from either one.... But how much longer are they going to be "good and fertile" ?
We don't keep alot of heifers out of first calf heifers.... unless they raise a real nice one... then we know that they have milked good, and the calves often catch up by the time they are ready to calve themselves and we have to look back to see who they are out of.
We want a CE bull so that the heifers can spit them out and they get up and go about being a momma.... traumatic calving sometimes makes a heifer just not want to be a momma, or worse... paralyses her and then what have you got.
