manure to grow algae and probiotics

Dear All
	I received a request for information from Keith Wyatt in Chile 
(his email address is kwyatt@uec.inta.uchile.cl)  
	A) He is interested in using manures to grow algae using nutrients 
in animal manures and then using it as either a feed supplement or fish feed.
	B) he is also interested in the general opinion about the use of
probiotics as a feed supplement for chicken, cattle and hogs. Does it work?
What does the data indicated?

	Please answer Keith directly (kwyatt@uec.inta.uchile.cl)
