本文对木瓜蛋白酶在对虾饲料生产过程中的活性变化及在养殖中的应用效果进行了初步研究。研究表明：木瓜蛋白酶在饲料生产加工中，损失较大，只保留了原有活力的３１％。在饲料保存及海水中稳定性相当好，仍保持原有活力的９０％以上。在对虾养殖中显示了一定的促生长效果，可提高产量５％。说明在对虾饲料中添加木瓜蛋白酶具有一定的效果 In this paper, papain activity in the production of shrimp feed changes in the breeding and application of a preliminary study. Studies have shown that: papain in the feed production and processing, the loss of large, retaining only 31% of the original vitality. In feed preservation and seawater stability is quite good, still maintain the original vitality of more than 90%. In shrimp farming showed some growth-promoting effect, can increase the yield of 5%. Description of shrimp feed added papain has a certain effect
