Alternative ingredients to reduce feed costs

Some Ingredient can reduce feed cost like corn DDGS , Cassava meal, Copra Meal and Palm Kernel Meal especially in South East Asia, But we have to concern with ANF and some NSP content in the Ingredient. So the best way if we also use some Feed Enzyme like Phytase and NSP Enzyme (Beta mannanase, Xilanase and Glucanase etc)

I am very interested in this topic. A few years ago and until now we are still trying to find alternative feed ingredients, there is a good one maggot is produced by bioconversion of palm kernel meal. Maggot good for freshwater fish such as catfish, tilapia, Channa micropeltes, etc. but I have not tried it for marine fish. I use a maggot of black soldier fly larvae (Hermetia illuscens), not the maggot of Musca domestica or Calliphora sp. Trims Ediwaman Jambi Freshwater Aquaculture Development Centre
