I have had so many phone calls in the past few weeks that I just wanted to make a few comments about calving ease bulls and breeding decisions. Most of the people that I have had the opportunity to talk to about calving ease bulls are looking for the ultimate bull to use on their show heifer. Besides wanting a live calf on the ground and a live cow to feed it next spring they want one that stands a chance a being their next show prospect. I can respect that. With the kind of money that most folks have invested I think that is the least we can wish for.
What most people are asking is if a proven calving ease bull will guarantee them an easy birth. The first question I always ask is how the female is bred. Many are happy to say that she is out of a popular calving ease bull and so should be an easy calver too. In most cases, however, when I ask more questions I usually find out that their heifer has some monstrous clubby genetics on the bottom of their pedigree. What that tells me is that their heifer has a 50% chance of being incredibly HARD calving and/or throwing a monster. So with that in mind, I point out to them that no matter what proven calving ease bull they use they still have a pretty good chance of having a larger calf.
Now, let's talk about calving ease bulls. I have talked to a lot of people that went out a bought a new yearling "heifer bull" this spring. I particularly love that term. A YEARLING HEIFER BULL! Now in my book nothing is a heifer bull if it has no progeny on the ground to justify calling it such. If you truly want to rest a little easier you buy a bull that has at least one set of calves on the ground with proven birthweights that point towards it actually being a calving ease bull. In my book there is just too much risk involved in turning out an unproven bull with my heifers. You not only have no proof on the bull side but if your females have any genetics in the top or bottom of their pedigree that lends to large calves chances are your vet is gonna love you next spring.
Proven Calving Ease Bulls: Are they 100% a sure thing? NO WAY! I have a cow that will throw a 110 - 140 lb calf every year without fail. I have never assisted a birth but she makes monsters. If I bred her to a proven calving ease bull with an aveage BW of 75 pounds does that mean that she will have a small calf? NO! That means that I probably have a 50% chance of having the smallest calf she has ever raised. I would guess in the 90+/- range but have never used a calving ease bull on her. I have had a lot of reports on a bull that we are promoting and people are thrilled with the birthweights. For the most part the calves are averaging in the upper 70's out of mature cows and heifers. There have been a few in the low 90's. Does this worry me? No. You have to factor in the ENTIRE picture. Cow pedigree (top and BOTTOM), female body condition and frame size, if female was a recip, environment and numerous other factors have to be measured in.
I have used a club calf sire extensively that has never had a calf born on our farm over 90 lbs. In fact, most are in the upper 70's and low 80's. Would I use him on heifers? NO WAY! I have pulled more of those calves than any other sire group. Big heads and square shoulders completely eliminate him from the calving ease category. He's not being promoted that way so I am not complaining. I simply want to point out that light birth weights do not make a calving ease sire either, even if he is proving to keep the calves under 90 pounds.
So, my advice is...
Know and understand your female's ENTIRE pedigree...not just who her sire is.
Don't use a "new" bull that claims he is a calving ease sire...especially if his mother isn't remotely calving ease oriented.
When you buy a bull to use on your heifers study BOTH sides of the pedigree and spend the money on a proven bull!
Go look at calves and/or the real bull before you make your breeding decisions.
At the very least, pick up your phone and talk to the bull owner. In most cases they won't steer you wrong and they will help you make wise decisions.
