Abstract
The invention discloses a parent scylla paramamosain compound feed and a preparation method thereof. The compound feed is characterized by containing the following components in parts by weight: 30-35 parts of fish meal, 20-25 parts of sleeve-fish meat meal, 5-10 parts of krill meal, 3-5 parts of clam worm meal, 15-20 parts of bean pulp, 2-3 parts of fish oil, 3-5 parts of soybean lecithin, 15-20 parts of flour, 0.5-1 part of cholesterol, 0.5-1.0 part of vitamin mixture and 0.5-1.0 part of mineral mixture. The preparation method comprises the following steps of: mixing the components; quenching and tempering the mixture under a certain steam pressure and at a certain humidity and temperature; and curing the quenched and tempered mixture at a certain temperature under a certain pressure for a certain period of time, and extruding the mixture into a feed with the particle size between 3 millimeters and 4 millimeters to obtain the parent scylla paramamosain compound feed. The feed has the advantages of meeting the requirements on overwintering cultivation and nutrition needed in a gonadotropin development period of parent scylla paramamosain, remarkably increasing the egg laying amount and the fertilized egg hatching rate of parent scylla paramamosain, enhancing the resistance of the parent scylla paramamosain to pathogenic microorganisms, and lowering the emission of nitrogen and phosphorus.
