I thought of you today Anita. I had the great joy of delivering goats today and wound up at a farm that uses a homegrown fodder system.
He simply uses 3.5 gallon buckets and fills them up 1/4th of the way up with wheat, oats, milo (he is in north Texas) black oil sunflower seeds and barley (he orders his from Azure Standard since they are organic). He is to far to get organic grains from central Texas which would make this much cheaper for him. He gets his oats and wheat at his local feed store. The longer he has done this the more and more whole oats and barley he adds to the mix, after talking with me today he is going to ditch the BOSS, it is not increasing his fat at all in the limited amounts he is feeding.
After soaking for 12 hours (he does rinse his grain really well before he starts and he also adds rock salt to the soaking water (worrying about mold). He then dumps this into, 3.5 gallon buckets with holes (about straw size) in the bottom and sides of the bucket. As he does chores twice a day he runs water through the buckets and dumps them from one bucket to a clean bucket (this keeps air in all the grain and it also separates the mats. He puts one pound into each bucket because it how much he feeds to his 8 milkers. Although the soaking bucket needs to have a lid on it, these sprouting buckets did not have lids and were not in the dark.
So 24 hours soaking, 24 hours sprouting, then he dumps them into steam table plastic trays from Sams, we use them for sausage making. Once again with holes in the bottom of them. He soaks them twice a day at chores, and feeds them on day 7. So the seeds he is soaking today will be fed in 7 days. These sit in cafeteria trays that not just catch the water to keep it from dripping but keeps water for the roots to find if they are drying out between soakings.
He isn't going to do an automatic watering system because he has to milk twice a day, he only feeds the sprouted grains to milkers twice a day, so he won't have to do the sprouts if they aren't in milk...kind of logical
The milkers get only alfalfa pellets on the milkstand and he feeds 1 tray (about 1 pound of sprouted grain) in the morning and 1 bucket in the evening worth of the sprouts to all 8 goats. So that is 2 pounds of grain for everyone in two feedings. His feeders are like mine in fact he saw mine from facebook.
He doesn't put minerals in the sprouts he feeds a loose mineral instead. He does feed grass hay in the winter like I do and his goats do have some browse although he is much more heat stressed than me here, more like what I looked like last year.
He does all of the soaking and sprouting in his laundry room, he has all the sprouting trays on a table on his deck near the waterhose.
His does are beautiful, very well fed, very good flesh and being there at chores, very good milkers, they are LaManchas.
You have to control airflow, lack of air causes mold. He has had a fan running on his sprouts most of the summer. He has no problems with sprouting since he does it in the house, with the winter, but you are so much colder, all he does is put black plastic over his trays if he is going to get a frost and we have a whole handful of freezes.
He likes using the steam table trays, although he calls them chubs, because he can easily lift them and take them out to feed, letting most of the water drip out before he breaks it up and feeds it.
The guy he learned this from uses a mixer and mixes hay into his sprout mats, and feeds it like this.
In the feeder it looked like long grass that was dug up and thrown in the feeders, but looking closely it is all filled with grain at the bottom in the mat. While we stood there, they devoured what he put out, nothing left.
I was so impressed with this! Especially because there was little expense in the setup, and if you hate doing it, use it for starting plants for your garden or greenhouse
