Contessa had a single her first year just like her mother did. Chicory has gone on to have triplets the last two years. I'll admit that I back off the grain just a few weeks before I breed the doelings to drop their nutrition level a little in order to encourage a single kid. All my does go on to have after the first year, twins or triplets. A few even twin the first year but I'd rather they didn't. Both yearlings this year had singles.
Looking at the shiny healthy coat, you'd have to admit nutritionally, kidding didn't hurt Contessa one bit. So if you were to ask me why I kid at one year of age. I'd have to say because of my feed program which includes a vitamin and mineral supplement, and a copper supplement three times a year, I don't see a difference in waiting the extra year to gain more growth.
Also I don't want to wait another year with a disc bulging every other one down my back along with being over fifty years of age, I'd much rather wrangle a one year old doe onto the milking stand her first few weeks of training than a hefty two year old.
I gain financially as I have a kid to sell in the first year and I have milk. I also suspect that my does milk more when they are two years of age than a doe who didn't not kid their first year.
If my goats were raised exclusively on pasture, I'd most likely wait until they were one and a half years of age to breed, depending on their size. Then again, I wouldn't have the amount of money invested in them like I do in my situation.
So dairy goat owners, are you one of those who waits until their dairy goats are one and a half for breeding or are you in the same corral as I am? If so why? You might just change my mind.
