Some kind of local raw materials used as feed water. To find a simple, cheap, and has a sufficient volume, including waste by-product of producing tofu (soy milk. Or soy milk) layer of cotton seed meal, the cassava leaf beef in rubber.Find that and have the potential to be the raw material source of vegetable protein. Essential amino acids in protein but low especially methionine (Methionine) and toxins using in fresh or raw will toxins than the use in dry conditionsMeat meal, meat and bone meal, blood meal, feather meal have protein. A study and accepted as a feed material, especially in animal feed, bok. But the use of aquatic animals also reported relatively limited 2 protein from both sources.Methionine using limitation if used in high volume, and continuously for a long time, and will affect the growth decreased. The essential amino acid in the raw dishes.Raw material, and there are plenty of enough types. Fish waste from processing factory and the market. Even some of the production of industrial a fish meal or protein concentrate (protein hydrolyses).As far the fish meal Cement paste by various methods such as biological raw materials which are easy to find and locally, such as cassava or pineapple peel and chemical method.There is an essential amino acid, intact, despite the problems in collecting, transport and food value is high variance,
.Apple snails and insects, some species such as ascetic protein similar to fish meal, but limitations have remember falling in some seasons and only in the area of the Mekong River.And need further study. Although alternative raw materials mainly have limitations on the use of essential amino acids and in low quantity.
