The ideal market weight for a wether, goat, is 65-80#, also the time that the animal is most expensive, target $1.25 per pound....This weight can be reached not long after weaning with not too much extra concentrate feed....So the value in goats is getting the animal as close to your target weight as can , limited by your breeding schedule and the condition of your doe, then weaning and finishing your wethers with the least input for the most profit.....Meaning the animal is the most valuable when it is at the desired markt weight and condition...that would be when you indicate you would buy them, just weaned...thats where producers make all the money, selling weaned wether kids for market. After they have reached this stage they decrease dramatically in efficiency as well as market price...I raise boer goats by 100 days all my kids are gone to market, except show prospects and replacement stock, there is no added value in keeping them longer....I owuld say if you want to appreciate a value you would have to have does that have kids for your family then feed them olut to whatever weight you like...Instead of taking a "big hit" when you try to buy them just weaned...jmo...I have a few left if you'd like to try some and are close to Indiana...for referrence I sold a wether kid yesterday that was just 90 days old, he was in the 55-60# range, just weaned and started on feed.
