Ok, I'm trying to figure out my milk profits (just an estimate to give me an idea), so I have some questions for people with large breed milk goats.. Say I have a Nubian, and at her peak, she milks a gallon a day. How long is the AVERAGE lactation? Not how much your specific doe gives, I want the average length. Given upon the average lactation, how many total gallons would that goat give for her laction? That includes when she tapers off until dry.. I know it is different for each doe though.. We dry our does off when they start giving about a cup a day. I had it all figured out at one point, but now I'm questioning my estimate..
