I don't make my own goat feed, but I do add supplements.
First, they get free-choice goat minerals, bicarbonate soda, zinpro 4-plex, kelp, and yeast culture. Along with a sulfur block.
I feed them Blue Seal dairy goat with black sunflower seeds, shredded beet pulp, steamed flaked barley, whole oats, alfalfa pellets, and flax seed.
I have seen better conditions and more production since I have done this management. They also are much more immune to worms also.
6 parts whole oats
2 parts calf manna
2 parts BOSS
1 part Beet pulp
mix well...use one part mix to 3 part alflalfa pellets...
our scoops are 3 pound plastic coffee cans..but your scoop can be anything used in this measuring system...
most our girls get 2-3 coffee can fulls...larger gals and more milk might get more while those who do less milk or smaller gals get less....
