摘  要:
以健康的初始体质量(50.66±0.26)g草鱼(Ctenopharyngodon idellus)为试验对象,在室内[(19±3)℃]单循环控温养殖系统中进行6周饲养试验,以鱼粉为对照组,β-伴大豆球蛋白的添加量为40 mg/g,大豆球蛋白的添加量为60 mg/g,配制成3种等氮(粗蛋白质量分数为30%)、等能(15.6 MJ/kg)的半精制饲料,探讨大豆主要抗原蛋白对草鱼肌肉主要营养成分的影响。结果表明:大豆主要抗原蛋白使草鱼肌肉中粗蛋白含量极显著下降(P<0.01),对肌肉中水分、粗脂肪、粗灰分、氨基酸总量、必需氨基酸总量和鲜味氨基酸总量影响不显著(P>0.05)。可见,在本试验条件下,草鱼配合饲料蛋白水平为30%时,在其配合饲料中分别添加β-伴大豆球蛋白(40 mg/g)和大豆球蛋白(60 mg/g)显著影响了草鱼肌肉中粗蛋白的含量。

摘  要:
A growth trial was conducted on Ctenopharyngodon idellus with the initial weight(50.66±0.26)g for 6 weeks at controlled temperature(19±3)℃ in single recirculating system.The fish were fed with three isonitrogenous(30%) and isoenergetic(15.6 MJ/kg)diets formulated with purified β-conglycinin 40 mg/g diet and glycinin 60 mg/g diet,respectively to investigate the effects of main soybean antigens on nutritional components in muscle of Ctenopharyngodon idellus.The results indicated that crude protein content in muscle of Ctenopharyngondon idellus fed with β-conglycinin or glycinin significantly declined(P<0.01).Glycinin or β-conglycinin had no significant effects on the contents of water,fat,ash content,and contents of total amino acids,total essential amino acids and total flavor amino acids in muscle(P>0.05).Therefore,soybean antigens had significant effects on the nutritional components in muscle of Ctenopharyngodon idelluswhen the protein content was 30% in the trial and the content of β-conglycinin or glycinin was over 40 mg/g or 60 mg/g in the juvenile fish diets,respectively.
