I have 2 nubian 2 lamanchas 2 alpines and the rest are sannan. We got them as bottle babies and we raised them on corn and hay. We didnt know they needed vaccines untill now so we are going to get that done soon.
I'd first get the fecal done to verify any parasites. We are diagnosing on the internet and not physically looking at your goats.
If the fecal shows coccidia, then get Sulmet or DiMethox. I would drench each goat individually to make sure they get the proper dosage. 1cc per 5 lbs day 1 and 1cc per 10 lbs days 2-5. Depending on how bad the coccidia is, I would do it again in 2 weeks.
They do get alfalfa on top of the siliage. There is a guy around here that milks goats and all he feeds them is siliage and hayliage. When they were babies a few of them had coccidioses we gave them dimethox for a while but we would only put a cap full in thier water?
Goats need to have roughage in the form of browse during the growing season as well as good quality hay..mixed grass, alfalfa, timothy/clover when the growing season is done. Alfalfa pellets help with added nutrition.
Giving only corn doesn't do much for them as far as balanced nutrition... if it's not been crimped, cracked or steamed they can't process it.
As far as the treatment you did with the DiMethox, adding it to water and not giving it according to weight in individual doses usually does no good to rid the one with the infection.
Feeding that many goats to add weight and condition can be over whelming, I'd start the ones needing it most on a 16% goat feed and add in dry beet pulp shreds.
I would consider switching to ALL free choice alfalfa, a good loose goat mineral like Sweet Licks Meat Maker, and grain. A 16-18% protein mix should be good. They should get at least 1 lb per 100 lbs of body weight, but if they need more weight, you could bump up to 1.5 lbs or 2 lbs. Ground flax seed and safflower oil also help. You can supplement with something like Calf Manna. It is high protein and great for weight gain. Same with the grain. Start with 1/2 lb per 100 lbs of body weight, and if they aren't showing improvment after 2-3 weeks, bump up their ration. Have a fecal run for worms and cocci, because those can really run a goat into the ground... Is anyone have loose poop? Are eyelids and gums nice bright pink or red?
The only thing I have avalible to feed them is corn (grinded), corn siliage, hayliage, soybean meal, alfalfa mixed with grass hay, and minerals and salt,. Could anyone tell me how if all these things I should be feeding them morning and night? Any help/advice is as appreciated
