鳖是以食动物性饵料为主的杂食性水生动物,对饲料的要求与其它水产动物有显著不同,人工养鳖要想获得高效益,就必须针对鳖对营养的需要,广辟饲料来源,并实行科学投喂。 1.鳖对饲料的营养要求 鳖的生长发育需要适当的蛋白质、脂肪、碳水化合物、维生素和无机盐。据湖南省水产研究所的实验,在最适宜生长发育的水温条件下,幼鳖饲料中蛋白质的适宜量为47％～49％。成鳖为43％～45％。这表明,鳖对饲料蛋白质的要求较高,饲料中蛋白质含量低,鳖将会出现食欲不振、生长缓慢、发育不良等现象,甚至发生疾病。脂肪是能量的重要来源,在配制鳖饲料时,添加3％～5％的油脂,能提高幼鳖和成鳖的生长速度和饲料的利用率。植物性饲料用量较少,但 Soft-shelled turtle food-based omnivorous aquatic animals, the requirements of feed and other aquatic animals are significantly different artificial turtle in order to obtain high efficiency, we must address the needs of turtles nutrition, broaden feed sources, And the implementation of scientific feeding. 1. turtle nutrition requirements for feed The growth and development of turtle need appropriate protein, fat, carbohydrates, vitamins and inorganic salts. According to the Hunan Provincial Institute of Fisheries experiments, optimum temperature in the growth and development conditions, juvenile turtle feed protein in an appropriate amount of 47% to 49%. Into turtle as 43% ~ 45%. This shows that turtle higher requirements for feed protein, feed protein content is low, turtle will appear loss of appetite, slow growth, poor growth and other phenomena, and even diseases. Fat is an important source of energy. Adding 3% -5% of fat to the preparation of soft-shelled turtle feed can increase the growth rate and feed utilization of the soft-shelled turtle and the soft-shelled turtle. Plant feed consumption less, however
