[0041] The present invention provides a kind of preparation method of above-mentioned compound feed, it comprises the following steps:
[0042] (1) Mix the fish meal, corn gluten meal, peeled soybean meal, peanut meal, flour, shrimp shell powder, premix, cellulose, antioxidant, yeast hydrolyzate, fatty substance, calcium source and amino acid, and then crushed, then sieved;
[0043] (2) Conditioning, granulating and aging the undersize material obtained in the step (1) to obtain a compound feed.
[0044] In a preferred embodiment of the present invention, in step (1), the above components are mixed and then pulverized on a pulverizer, and the pulverized particle size is 80-100 mesh.
[0045] In a preferred embodiment of the present invention, in step (1), the pulverized mixture is sieved, and the sieve is 80-100 mesh. The screen is a stainless steel screen, which is commonly used in the feed industry.
[0046] In a preferred embodiment of the present invention, in step (2),...
Embodiment 1
[0056] A kind of yeast hydrolyzate replaces the Penaeus vannamei compound feed of fish meal, by mass percentage, consists of the following raw materials:
[0057] Fish meal 22.5%, corn gluten meal 5.5%, peeled soybean meal 20.05%, peanut meal 6.5%, shrimp shell powder 3%, flour 26%, phospholipid 2%, fish oil 2.10%, soybean oil 2%, multidimensional 0.5%, multimineral 2 %, VC 0.03%, choline chloride 0.03%, calcium dihydrogen phosphate 2.8%, cellulose 1.89%, methionine 0.05%, ethoxyquinoline 0.05%, yeast hydrolyzate 3%.
