I keep a small farm in which I raise chickens and pigs (less than 200 of each) in Kenya, East Africa. I have access to the following raw materials: - soya - fish meal - wheat germ - corn germ - lots of wheat and corn husks (vitamin supplements are available but very expensive) - Lots of green vegetables How can I make my own feed, without having to be very precise (weights etc) as the labour available is not very literate.
