“I think that's a big advantage if you don't have a lot of land,” the farmer said. “You can produce a tremendous amount of feed in a very, very small area with a very little amount of water.”
However, UC Cooperative Extension alfalfa specialist Dan Putnam noted in the story that the system may not pencil out.
"If you really apply a little bit of economics to it and animal nutrition to it, it doesn't appear quite as promising as one might think," Putnam said.
There is no question that animals find the sprouted barely delicious. Online videos show cattle and horses "gobbling up sprouted grain like a vegetarian at a salad bar," Putnam wrote in a 2013 blog post that asked Does hydroponic forage production make sense? Things are not always as they seem. Animal ration calculations are based on dry matter since water is provided separately.
"A feed with 90 percent water (such as sprouted grain) has considerably less 'feed value' than something with only 5 percent water (such as the grain itself), on a pound for pound basis," Putnam's blog post says.
Feeding sheep sprouted barley makes sense to Mario Daccarett, the owner of the Golden Valley Farm. He said cheese made from his sheep's creamy milk is sold in places like Whole Foods.
"They have our cheese there and they tell me that our Golden Ewe cheese is the best for grilled cheese sandwich ever, and they have over 500 different varieties of cheese there," Daccarett said.
The farmer feeds his sheep one part oats and hay and one part sprouted barley.
“You do the math and you say, 'Well, yeah, it might not work,' but once we started doing it we found out that sheep tend to eat less, more nutrition, more enzymes,” Daccarett said. “So they become more efficient.”
