Cassava in Broiler diets

I´ve read with great interest your article about Cassava Products in Diets for Broiler Chickens. It was a great work. Thousands of farmers have gone out of business in Nigeria as a result of high cost of production triggered by shortage of grains, most importantly maize. I´ve lost over two thousands birds as a result of my worker trying to cut corners in my absence. My business eventually collapsed. I am very curious about this development. My question is, can maize be substituted with cassava in layer birds? If possible, can the substitution affect their layerbility? I know for sure this development is not new. In nigeria for example, we got a renowned successful farmer feeding cassava to his birds. What i am not sure of is if the layer stock are included.

Good days, sir, very interesting please give the chat table of the use of cassava and every other ingredient for broiler and turkeys feeds composition by kg. Thanks.
