摘要
以鱼粉、豆粕和玉米蛋白粉为待测原料,分别与暗纹东方鲀基础饲料配制成3种试验饲料,其中含有70%的基础饲料和30%待测原料,研究暗纹东方鲀对3种蛋白质原料的消化率;用豆粕、玉米蛋白粉替代部分鱼粉配制基础饲料,分别在基础饲料中添加0.050%和0.075%的酶制剂,研究酶制剂对暗纹东方鲀配合饲料表观消化率的影响。实验结果表明:暗纹东方鲀对鱼粉、豆粕和玉米蛋白粉蛋白质和干物质的消化率都较高,蛋白质的消化率分别为93.40%、91.83%和94.97%;干物质的消化率分别为88.13%、85.73%和89.25%。饲料中添加酶制剂能显著提高暗纹东方鲀蛋白质和干物质的消化率,但0.050%和0.075%的实验组之间没有显著性差异,可通过添加0.050%的复合酶制剂来提高暗纹东方鲀对饲料的利用率。研究亮点:研究暗纹东方鲀对鱼粉、豆粕及玉米蛋白粉3种蛋白原料的消化率,并结合肉食性鱼类的消化生理研究酶制剂对消化率的影响,为开发暗纹东方鲀低鱼粉饲料提供重要的基础数据,是开展渔业生态、低碳研究的一个关键步骤,有前瞻性和创新性。
Apparent digestibility coefficients（ADC） of three selected feed ingredients fishmeal,soybean meal and corn gluten meal of Takifugu obscurus were measured.A basal diet was formulated to contain 45.52% crude protein,and three kinds of test diets were formulated by combining the basal diet and each of the tested ingredients at a ratio of 70∶30.Chromicoxide was added at 0.5% in the basal diet and test diets as inert-marker.A basal diet was formulated to contain 45.40% crude protein,two experiments diets were prepared by adding 0.050% and 0.075 % multi-enzyme,respectively,the apparent digestibility of above three diets were measured.The results showed that the protein apparent digestibility of fish meal,soybean meal and corn gluten meal were higher,93.40%,91.83% and 94.97%,respectively.Feed dry matter apparent digestibility of fish meal,soybean meal and corn gluten were 88.13%,85.73% and 89.25%,respectively.Multi-enzyme supplemented could significantly improve the apparent digestibility of protein and dry matter of Takifugu obscurus.However,apparent digestibility has no significant difference between the 0.050% and 0.075% experimental groups.
