摘要:
在基础饲料中添加0.08 g/kg黄霉素为对照组饲料,添加15 g/kg中草药Ⅰ、20 g/kg中草药Ⅱ、0.2 g/kg合生素、0.6 g/kg复合酶作为试验组饲料,用上述5种饲料在水泥池中饲养日本沼虾40 d.测定日本沼虾胃、肝胰脏中的胃蛋白酶、类胰蛋白酶、淀粉酶及肠道中的蛋白酶和增重率.结果表明,试验组添加剂对胃、肝胰腺消化酶(胃蛋白酶、类胰蛋白酶)及增重率有显著性影响(P<0.05),但对肠蛋白酶、肝胰腺淀粉酶无显著影响(P>0.05);除合生素组中胃组织的胃蛋白酶、中草药Ⅱ组的胃组织类胰蛋白酶、胃淀粉酶要稍低于黄霉素组相应酶的活力外, 其余所测定的各消化酶活性及相对增重率都要高于黄霉素组相应结果. 中草药Ⅰ 、中草药Ⅱ 、复合酶和合生素组的增重率较黄霉素组分别提高13.10%、16.53%、22.07%和32.22%, 表明试验组的饲料养分消化利用更为充分.
Abstract:
Flavom yc in as feed additivew as m axed w ith basal feedstuff to form con tro l g roup feedstuff and the added level w as 0.08 g /kg. Four k inds o f feed add itive, wh ich we re Ch inese herba lmed ic ine Ⅰ , Ch inese he rbalm edicine Ⅱ , synb iotics and com pound enzym es, w erem ax ed w ith basa l feedstuff separate ly to form tria l group feedstu ffs. The added leve ls of them w ere 15 g /kg、20 g /kg、0.2 g /kg and 0.6 g /kg respective ly. The experim entalM acrobrach ium N ipponense ind iv idua ls w ere cu ltured in concrete tank for 40 d feeded w ith the five kinds of feedstuffs. Then, the activ ities of am y lase, tryptase and peps in in the stom ach and the hepatopancreas, as w e ll as the activ ity of intestine protease, and the re la tive w e ight ga in rate we re investigated. One-w ay ANOVA show n tha t feed additives o f trial g roups had sign ifican t effects on the ac tiv ities o f digestive enzym es in the stom ach and the hepatopancreas ( pepsin, tryptase) and on the re lative w e ight ga in rate( P < 0.05) , how ever, no significant differencesw ere found in ac tiv ities o f the intestine pro tease, as w ell as the hepatopancreas am y lase(P > 0. 05). The exper iment shown that the re lative w e ight ga in rate and m ost o f the d igestive enzym es activ ity item s of flavomy cin group w ere sign ificantly low er than that ones o f o ther g roups respective ly, ex cept pepsin in stomach of com pound enzym es group, as w e ll as tryptase and am y lase in stom ach o f Ch inese herbal m ed icine Ⅱ g roup. The re lative w e ight ga in rates o f Ch inese herba l m ed ic ine Ⅰ, Chinese herbal m edic ine Ⅱ, com pound enzym es and synbiotics g roup w ere h igher than that one of flavom yc in group by 13.10%, 16.53%, 22. 07% and 32.22% respectiv ely. So it was conc luded that the feedstuffes o f the four groups can be d igested and absorbed m ore efficien tly than the feedstuff o f flavom ycin g roup.
