I have 6 Nigerian Dwarfs: 4 currently dry does, one who should be preggers and due in November, and a whether. I really wish I had a way to feed them separately, but I don't, so I feed with the pregnant one in mind.
This is what they're currently getting:
3 quarts 12 % all stock. I CANNOT find 12% goat feed, in any of the stores here.

But I read in my book Storey's Guide to Raising Dairy Goats that pregnant ones are not supposed to get more than 12% feed until right before kidding so the babies don't get too large. I would rather have goat pellets, but I definitely don't want the babies to be too big! When she gets closer, I'm going to switch back to the 16% feed they normally get.
The brand of 16% goat pellet I get them is Dumor- is this a good brand, or should I look for a different one?
1.5 Quarts Alfalfa Pellets. Is this enough for them? Or should the alfalfa - grain ratio be different? Sorry I can't remember what brand the alfalfa is....
They also get Bermuda hay, Sweetlix minerals, and baking soda free choice.
This is the guaranteed analysis for the mineral:
Calcium (Min) .............................. 14.00%
Calcium (Max) ............................. 16.80%
Phosphorus (Min) ...................... 8.00%
Salt (Min) ...................................... 10.00%
Salt (Max) ..................................... 12.00%
Magnesium (Min) ....................... 1.50%
Potassium (Min) ......................... 1.50%
Sulfur (Min) .................................. 1.50%
Iron (Min) ...................................... 1.25%
Manganese (Min) ....................... 1.25%
Zinc (Min) ..................................... 1.25%
Cobalt (Min) ................................. 240 ppm
Copper (Min) ............................... 1,750 ppm
Copper (Max) ............................... 1,810 ppm
Iodine (Min) .................................. 450 ppm
Selenium (Min) ........................... 50 ppm
Vitamin A (Min) ............................ 300,000 IU/lb.
Vitamin D-3 (Min) ........................ 50,000 IU/lb.
Vitamin E (Min) ............................ 400 IU/lb.
They are also in an area that still has some browse. They've eaten most of the "good stuff" (or what they seem to think is the good stuff, haha) down, but there is still tons of grass and such out there.
Sorry this has gotten so long. I want to do everything right and the feeding is the part that confuses me the most.

No matter how much I read about it, I'm always confused about which brand is better, how much each goat should get, etc.
So, I would really appreciate it if the more experienced people out there could tell me how good my feeding plan is, or what I need to change? They're all in good condition, not too fat as far as I can tell, nor too skinny (based on feeling spine, chest, and above the rump, not stomach size.)
Thanks everyone! SO SORRY this is so long!
