Thanks for the follow!
Great question and I wish there was an easy answer to, "at what age would you recommend for butchering?". The quick answer is, it depends.
Let me explain. First, it's more of a weight instead of age. For instance, the ones pictured were an average of 61 lbs and 130 days old. For my family, we believe the best taste and texture of the meat comes with meat kids, between 60-65 lbs. Now, if you are selling to the market, it's important to know the market trends and what weight ranges the buyers are looking for at what time of the year. Some weights will bring the best prices depending on the season.
In my experience, those wanting goat kids for the Easter holiday, will prefer a 40-45lb kid so they may be roughly 65 to 70 days old. For our community that celebrates Cinco-de-Mayo, they are typically are looking for a 50-55lb kid, so at that point, closer to the 90 day old range. We have had a couple customers that have purchased from us that celebrate Eid al-Adha in the fall and they told me they prefer a 70-75 kid so that would put them at around 8 or 9 months old.
So really there is no right or wrong age to when to butcher. It really is just a preference. Hopefully this has helped answer your question though. One last thing to know, different goat breeds gain weight at different rates. We raise Kiko goats, so all the weight/age figures are based on weights that I'm familiar with off the farm.
