骨粉是鱼混合饲料的重要成分。过去,一般都将骨粉作添加剂直接添加到鱼饲料中,但近年来的研究证明,骨粉经酸化后作饲料添加剂养鱼,不仅制作方便,成本较低,而且喂鱼的效果好。 对骨粉进行酸化的方法是:在100克骨粉中,加入25毫升浓度为99％的冰醋酸,经充分拌匀,反应即为酸化骨粉。这种酸化骨粉,每公斤含游离磷酸盐138.8克;而普通骨粉,每公斤仅含游离磷盐2.8克。由于骨粉酸化后游离磷酸盐提高了48.5倍。所以能促进鱼的生
Bone meal is an important component of fish mixed feed. In the past, bone meal was generally added as an additive directly to fish feed. However, studies in recent years have proved that it is not only easy to manufacture and lower in cost but also good for fish feeding due to the acidification of bone meal for fish feed additives. The method of acidification of bone meal is: add 100 ml of bone meal to 25 ml of glacial acetic acid at a concentration of 99%. After sufficient mixing, the reaction is acidified bone meal. This acidified bone meal, containing 138.8 grams of free phosphate per kilogram; and ordinary bone meal, containing only 2.8 grams of free phosphate per kilogram. Free phosphate increased 48.5-fold due to bone meal acidification. So can promote the fish’s life
