The invention discloses a compound premix for orange-spotted
grouper. The compound premix is composed of compound vitamins and compound minerals. The per
kilogram of compound vitamins contains 7000IU of VA, 2500 IU of VD3, 7.8g of VE, 1.0 mg of VK3, 0.08g of VB1, 0.04g of VB2, 0.08g of VB6, 6.1g of
calcium pantothenate, 6.25g of
nicotinamide, 0.02g of
folic acid, 6.2g of coated VC, 3.80g of
inositol and the balance of wheat middling. Per
kilogram of compound minerals includes 220g of Na2HPO4, 80g of KCl, 14g of MgSO4, 43.7g of
amino acid chelated iron (12%), 2.0g of
zinc amino acid chelate (10%), 2.4g of amino acids chelated
copper (10%), 0.10g of KI, 0.20g of CoCl2, 3.6g of
amino acid chelated
manganese (8%) and the balance of a light
calcium carbonate powder. The compound premix provided by the invention is added with amino acid chelated iron,
zinc,
copper,
manganese and coated VC to
gain better usage effect. The product can increase the output of orange-spotted
grouper in unit water in the factory farming mode by more than 20%, decreases feed coefficient to below 1.3, and greatly improves feed efficiency.
