I have 4 does that I plan to breed in the next month or two and one buck. I have recently started feeding a mixture of dumor goat feed, alfalfa pellets, beet pulp shreds, and whole oats. I buy the 50 lb bags of each and dump it in a big tub and mix. I have a 5 quart feed scoop. How much per goat should I feed? Also should I add anything to the mixture?
