Production process of soft granulated feed containing astaxanthin crude products for pseudosciaena crocea

The invention provides a production process of soft granulated feed containing astaxanthin crude products for pseudosciaena crocea. The method comprises the following steps: S1, preparing the following raw materials in percentage by weight: 15-17% of fish meal, 2-4% of lecithin powder; 10-12% of hydrolyzed fish protein powder, 2-4% of phagostimulant, 3-5% of beta-glucan powder, 6-8% of carrot powder, 2-4% of carrageenan powder, 4-6% of spirulina powder, 9-11% of vital gluten, 5-7% of scallop powder, 6-8% of somatotropin reagent, 16-20% of haematococcus pluvialis powder and 4-10% of astaxanthincrude product solution. The prepared soft granular feed for the large yellow croakers is high in food intake rate and complete in nutrition, the growth speed of the large yellow croakers can be increased, and the breeding survival rate is high. 本发明提出了添加虾青素粗制品的大黄鱼软颗粒饲料生产工艺，包括以下步骤：S1：准备以下重量百分比的原料：鱼粉15-17%、卵磷脂粉2-4%、水解鱼肉蛋白粉10-12%、诱食剂2-4%、β－葡聚糖粉3-5%、胡萝卜粉6-8%、卡拉胶粉末2-4%、螺旋藻粉4-6%、谷朊粉9-11%、扇贝粉5-7%、促生长素试剂6-8%、雨生红球藻粉16-20%和虾青素粗制品溶液
