在实验室内对植物蛋白浓缩物替代PK-C型开口饵料中的鱼粉进行了研究。另外,在生产条件下研究了以不同工艺生产的鱼粉做成的PK-C型配合饵料的投喂效果。后者是出于饲料工厂因某些原料质量差或者短缺,难以使配合饵料各种成份的含量保持恒定。 PK-C型开口饵料的组成:微生物合成制品50％、鱼粉35％、酪酸钠6％、小麦粉5％、饲料酵母1.5％、植物油1.5％、ПФ-IB型多 Plant protein concentrates were used in the laboratory to replace fishmeal in PK-C open-mouth feedstuffs. In addition, under the conditions of production, the feeding effect of PK-C type bait with fishmeal produced by different processes was studied. The latter is out of the feed mill due to poor quality or shortage of some raw materials, it is difficult to keep the content of various ingredients with the feed remain constant. Composition of PK-C type open bait: 50% of microbial synthetic products, 35% of fish meal, 6% of sodium butyrate, 5% of wheat flour, 1.5% of feed yeast, 1.5% of vegetable oil,
