摘要： 在基础饲料中分别添加０％ 、０ .２％ 、０ .３％ 和０ .４％ 艾佐迈(azomite) ,饲养平均体质量为(６４.２０ ±１.６８) g 的草鱼( Ctenopharyngodon idella) ８ 周,研究其对草鱼生长性能、肠道消化酶活性和血清非特异性免疫的影响.结果表明:饲料中添加艾佐迈可在不同程度上改善草鱼生长性能,其中添加０.２％ 艾佐迈使增质量率提高１６.６５％ ( P＝ ０.０８) ,饲料系数降低１２.９０％ ( P＜ ０.０５) ;添加０.２％ 和０.４％ 艾佐迈可显著提高草鱼的肥满度( P＜ ０.０５) ;艾佐迈对草鱼肌肉水分、灰分、粗脂肪和粗蛋白含量均无影响( P＞ ０.０５ ) ;添加０.２％ ～ ０.４％ 艾佐迈可在不同程度上提高草鱼前肠蛋白酶、淀粉酶和脂肪酶活性及血清超氧化物歧化酶(superoxide dismutase , SOD)和碱性磷酸酶(alkaline phosphatase , AKP) 活性,其中０.２％ 艾佐迈添加组可显著提高血清SOD 活性( P ＜ ０.０５ ) ;饲料中添加０.２％ 、０.３％ 艾佐迈对草鱼肝胰脏谷草转氨酶(glutamic‐oxalacetic transaminase , GOT) 和谷丙转氨酶(glutamic‐pyruvic transaminase , GPT) 活性无影响( P＞ ０.０５) ,但添加０.４％ 艾佐迈组显著降低了肝胰脏GOT 、GPT 活性.上述结果表明:饲料中添加艾佐迈可提高草鱼的生长性能和血清非特异性免疫力;草鱼饲料中艾佐迈添加量建议为０.２％ .
Abstract: An experiment was conducted to investigate the effect of azomite supplementation on growth performance , intestinal digestive enzyme activities and serum nonspecific immune of grass carp ( Ctenopharyngodon idella) . Four diets adding respectively ０％ (control group) , ０.２％ , ０.３％ , ０.４％ azomite were fed to grass carp with initial body mass of ( ６４.２０ ± １.６８ ) g for ８ weeks . The results showed that growth performance of grass carp was increased in different degrees by supplemental azomite in diets , in which mass gain rate was increased by １６.６５％ ( P ＝ ０.０８ ) and feed conversion rate ( FCR) was decreased by １２.９０％ ( P ＜ ０.０５ ) by supplementation of ０.２％ azomite in diet , compared with control group . Condition factors ( CF ) of fish fed with diet adding ０.２％ , ０.４％ azomite were significantly higher than control fish ( P ＜ ０.０５ ) . There was no significant difference in the contents of muscle moisture , ash , crude fat and crude protein among treatments ( P＞ ０.０５) . Activities of protease , lipase , amylase in intestine and superoxide dismutase (SOD) , alkaline phosphatase (AKP) in serum of
fish were enhanced in different degrees ( P＞ ０.０５) by addition of ０.２％-０.４％ azomite in diet . Fish fed with diet adding ０.２％ azomite had a significantly higher SOD activity than control fish ( P ＜ ０.０５ ) .Hepatopancreas glutamic‐oxalacetic transaminase ( GOT ) and glutamic‐pyruvic transaminase ( GPT ) activities were not affected by ０.２％ , ０.３％ azomite addition , but significantly decreased by ０.４％ azomite addition . The results above show that the addition of azomite can improve the growth performance and serum nonspecific immune function . The proper dose of azomite in grass carp diet is suggested to be ０.２％ .
