【摘要】 分别进行了二个试验以考察饲喂蚕豆对不同规格草鱼生长性能,肌肉成分和肠道蛋白酶活性的影响。试验Ⅰ以配合饲料,浸泡蚕豆或发芽蚕豆饲喂平均体重(535±50)g草鱼77 d;试验Ⅱ以配合饲料、发芽蚕豆饲喂平均体重(84.5±3.5)g草鱼68 d。结果表明,在两个试验中,与摄食配合饲料的草鱼相比,摄食浸泡蚕豆或发芽蚕豆均极显著降低了草鱼增重率(P<0.01),提高了饲料系数(P<0.01);鱼体肌肉粗脂肪含量极显著降低,胶原蛋白含量上升(P<0.01);前肠道蛋白酶活力极显著下降(P<0.01)。研究表明,投饲蚕豆可改变草鱼肌肉成分,但对草鱼生长性能和肠道蛋白酶活力有显著抑制作用。更多还原

【Abstract】 Two experiments were performed to study the effects of feeding broad bean on growth,muscle composition and pre-intestine protease activity of different sizes of grass carp.In Exp.Ⅰ,grass carp with body weight of(535±50) g was fed with formulated diet,immersed or sprouted broad bean for 77 days.In Exp.Ⅱ,grass carp with body weight of(84.5±3.5) g was fed with formulated diet or sprouted broad bean for 68 days.In both trials,fish fed with immersed broad bean or sprouted broad bean had lower growth rate,muscular fat content,pre-intestine protease activity(P<0.01) and higher FCR,muscle collagen content(P<0.01) than that of fish fed with formulated diet.Results above showed that flesh quality of grass carp could be changed,but growth performance and intestine protease activity decreased by feeding broad bean.更多还原
