开发固氮生物的绿萍Azolla良种为渔用饲料新资源。其营养价值特点,属于植物蛋白质饲料,氨基酸成份全面,中量、微量元素丰富,热量蛋白质比值(C/P)较低,可消化利用性高,适口性好,缺点是水分含量高及单位重量体积大。其合理利用须与其他干饲料适量配合饲用,关键在于预先测算来调配饲料的营养平衡。对罗非鱼、团头鲂、草鱼等饲养结果,鱼净增产49.4—117.6％,饲料利用效率提高63.1—74.2％,增强鱼的体质和有好的屠宰品质。
Development of nitrogen-fixing biological plants Azolla good new species for the fishing feed. Its nutritive value belongs to the plant protein feed. The amino acid composition is comprehensive, middle and trace element rich, the caloric value of protein (C / P) is low, the digestibility and digestibility is high, the palatability is good, the disadvantages are high moisture content and unit weight Big size. The rational use of dry feed with other appropriate amount of feed, the key is pre-calculated to adjust the nutritional balance of feed. For tilapia, bream, grass carp and other breeding results, net fish yield 49.4-117.6%, feed utilization efficiency increased 63.1-74.2%, enhance the fish’s body and have a good slaughter quality.
