I'm sure you'll get plenty of opionions on this one, but if you are having calving difficulties, you might try putting a LH bull on your heifers.
What kind of cattle operation do you have now?
Just curious, but where are the cattle located? Are they young cattle, heifers, older cattle etc?
Also is it a registered herd or a commercial herd? That would have a lot to do with price if you do decide to buy any.
The ranch I am working for is starting a herd of registered Longhorns. This is my first time to deal with them, and I have learned that most people either love'em or hate'em! There doesn't seem to be much inbetween. As for me, I can see that they have there place, but they are not for everyone.
