中文摘要:
      应用正交设计法(L9(34))配制九种试验饲料,对稚鳖配合饲料中蛋白质、脂肪、无机盐和总能的需要量作饲养试验。对增重率、饲料系数、日生长率、蛋白质效率等项指标进行综合分析。结果表明,在本试验条件下,影响生长的主要因素是蛋白质和总能。较优饲料的总能为320~340千卡/百克饲料,蛋白质为46.6%,脂肪为3~5%,无机盐为2~3%,总糖为21~28%。每百克稚鳖日需蛋白质0.648克,总能4.5~4.7千卡,脂肪 0.042~0.070克,糖 0.32~0.43克,无机盐2~3%,纤维素 20~22%。稚鳖饲料的最适能量蛋白比(C/P值)在7.0~7.55之间。
英文摘要:
      Feeding experiments were conducted to determine the daily requi-rement of protein, fat, mineral and general energy for juvenile turtle. The L9(34)table of orthogonal design method was employed to formulate nine diet combinatios.The experiments were conducted in 65 x 50 x 50cm aquaria under the following con-ditions,(1) water depth 20cm, water volume 65 l. (2) water flaw maintained at 2 .1-3.0 l/hr. (3) water temperature averaged 28 ±20℃, and (4) dissolved oxygen 0.12-1.94 mg/l,pH6.9---7.1 and NH4+-N 0.1---1.8 mg/l. The weight gain rate,feed conversion and protein efficiency ratio (PER) were used as the index to eva-luate the feeding effect. The results indicate that under the circumstances of the experiments the protein and general energy are major elements that affect the growth of the juvenile turtle. The optimum general energy of the most satisfactory diet is 320-340 kcal/100g feeds, pxotein 46.6%,fat 3--5%, mineral 2-3%, rar-bohydrate 21--28%. 100g juvenile turtle need 0.648g protein, 4.5-4.7kcal gene-ral energy,0.042---0.070g fat, 0.32--0.43g carbohydrate,mineral 2--3%and fiber 20----22%. The optimum calorie-protein ratio (c/p value) in formulated diet for ju-venile turtle is 7.00---7 . 55.
