My 4mo old Nigerian Dwarf wether is believed to have urinary calculi. 6 days ago, he and our other goat knocked over a 5 gallon bucket of chicken scratch feed that consists of mostly cracked corn and we assume he had himself a feast. The morning we discovered this, he showed symptoms which I incorrectly assumed to be bloat. He was given baking soda as well as Milk of Magnesia, vegetable oil and frequent rumen massages along with a few throat massages, yet symptoms did not stop. Unfortunately the vet was closed for the weekend, but he was brought in today. They tubed him and said very few gas escaped causing them to believe he was not bloated, however, they did give him mineral oil in case he had froth. Next they did a sonogram and told me his bladder is full and they believe he has urinary calculi and they're gonna cut of the tip of his penis.. I HOPE this procedure works, because if it does not, he is going to die since I can not pay $1300 for the other sugery. I want to prevent this from ever occuring ever again and do not want my second goat to have this. I read online about it and know about ammonium chloride and phosphorous/calcium ratio, but am confused.. The feed I have them on now is Blue Seal Meat Goat Grow and Finish, a medicated feed with decoquinate an ammonium chloride.. Apparently it was not so effective in preventing urinary calculi, BUT I have sweet coarse 14 mixed in with it.. They also have been getting on a regular basis, Manna Pro Goat Treat.... Have free choice baking soda and they get hay and browse.. The goats free range with ducks and chickens, so it's common for these mischievous little boys to get into the duck pens and chicken coops and eat layer pellets and duck food, as well as the scratch feed mentioned.. I do not know the mineral content of my well water. The goats also get goat mineral mixed into their feed every couple of days as well as a dose of probios a couple times per week. They have available to them free choice mineral and salt blocks, however, I do not know if they ever lick them. They get treats occasionally such as raisins, cheerios, watermelon, etc... I always offer leafy green veggies/herbs but they never accept it. The inflicted goat is 4mos old.. the other is 5 mos old... Can I take them off the medicated feed and feed them something else? The ducks also get into the goats barn and eat their food and it's not good for ducks to get medicated feed. What other feeds have ammonium chloride, if any? If I have to mix it in, how much do I use and how often, for prevention, and is it dangerous for ducks or chickens to ingest it? What brand of feed would be best for my goats if not the one I'm using now? I wonder also, is there such a thing as a multispecies feed? The goats, ducks and chickens all free range in the same area.. all the goat barn, chicken coops and duck pens are all open and they all eat each others food, except the chicks feed which is removed due to it being medicated..... Is it possible to feed all my animals the same feed and have them all getting their nutrition requirements? I thought about perhaps only feeding them in the evening when they're shut in for the night, but this makes me concerned about them not having exercise after eating, or them getting fat, etc and thought perhaps they need food available during the day when they're active.. I suppose I'm gonna have to do that. The other thing is my hay.. I do not know the nutritional value of it, nor the specifics.. One bale lasts quite awhile, so one I've had for bit has become brownish.. How long can hay be stored and how long does it remain safe for them to eat as long as it's dry and is not moldy.. I don't smell mold, so does this mean it's ok? This bale contains mixed plants and I see weeds, etc,... The bale I bought recently is bright and green, I gave them some of this before the urinary calculi and after, so, can this also be part of the problem? I bought it from a horse farm, but did not ask what kind it is, but perhaps alfafa or timothy is my guess... Horses get alfafa though, right? Could it be this hay that's the culprit here? Sorry for the ramble and assorted questions, but I'm in sad and desperate mood today hoping my little goat don't die and consequently believe I mismanaged and need to make changes.
