【摘要】 以Ｃｒ２Ｏ３为指示剂，采用间接测定法测定了０～４月龄稚鳖对所研制的３种稚鳖配合饲料中３种主要营养物质的消化率，并对３种稚鳖料及其主要营养物质的消化率进行了比较。结果表明：０～４月齿稚鳖对３种配合饲料中蛋白质、脂肪和碳水化合物的消化率平均值分别为：８６．６１％，８０．７４％，６４．９４％。１号料消化率最低，营养价值最低，而３号料消化率最大，营养价值最高。３号料最利于稚鳖消化和吸收，最适于甲鱼的生长。更多还原

【Abstract】 Using Cr 2O 3 as an indicator and the indirect method, the digestibility of the main nutrition: protein, lipid and carbohydrates of formula feed is calculated. Comparde all of the digestibility. The results shows that the average digestibility of protein, lipid, and carbohydrates of formula feed developed for 0～4 months turtle is: 86.61%, 80.74%, 64.94%. The comparision of these results indicates that the digestibility and the nutritional value of formula feed NO 1 are least, on the contrary, those of formula feed NO 3 are biggest. So feed No 3 is mostly fit for the young turtles digesting, absorbing, and growing.更多还原
