以初始平均体重为(7.01±0.05) g的青鱼为研究对象,配制5种等氮等能的试验饲料,以含40%豆粕的饲料作为豆粕对照饲料,含41%棉籽粕的饲料作为高棉籽粕饲料,并在高棉籽粕饲料中分别用0.342%的晶体赖氨酸(有效含量79%)、0.115%的七水硫酸亚铁以及0.342%的晶体赖氨酸+0.115%的七水硫酸亚铁等量替代面粉,以研究高棉籽粕饲料中补充赖氨酸和铁对青鱼幼鱼生长、免疫力及组织中游离棉酚含量的影响。每组设3个重复,每个重复30尾,试验期为8周。结果表明:与豆粕对照组相比,高棉籽粕组青鱼的特定生长率、血液红细胞数量以及血清补体4含量和总超氧化物歧化酶、溶菌酶活力均显著降低(P

An 8-week feeding trial was conducted to evaluate the effects of high cottonseed meal diet supple-mented with lysine and iron on growth, immunity and tissue free gossypol content of juvenile black carp [ ini-tial average body weight of (7.01±0.05) g]. Five iso-nitrogenous and iso-energetic experimental diets were formulated, one diet contained 40% soybean meal ( SBM) as the SBM control diet, one diet contained 41%cottonseed meal ( CSM) as high CSM diet, and the other 3 diets supplemented with 0.342% crystalline lysine (effective content was 79...
