在饲料中分别添加w/10-3为0,0.5,1.0,1.5,2.0维生素C(VC)。在饲喂胡子鲶Claris fuscus的第12、24、36和52天后,分别测定血液中自细胞吞噬活性、血清蛋白质质量浓度;在第24天,测定血液中淋巴细胞活性;在第12天和第52天,测定血清抗蛋白酶物质比活性;在第24天和第52天,测定血清VC质量浓度。结果表明,在饲料添加VC不能提高胡子鲶白细胞的吞噬指数(PI);对吞噬能力(PC)有影响;对淋巴细胞活性有明显的增强功能;血清抗蛋白酶物质比活性基本不受VC的影响;对血清蛋白质质量浓度有明显的提高作用;而对血清中VC质量浓度却有明显的降低作用。
In the feed were added w / 10-3 0,0.5,1.0,1.5,2.0 vitamin C (VC). Blood autophagic phagocytosis activity and serum protein concentration were measured respectively on days 12, 24, 36 and 52 after feeding on Claris fuscus, and on day 24, lymphocyte activity in blood was measured; on day 12 and day After 52 days, the serum anti-protease substance specific activity was measured. On the 24th and 52nd days, the serum VC concentration was measured. The results showed that dietary VC could not increase phagocytic index (PI) of leucocytes in white catfish, influence on phagocytosis (PC), enhance the activity of lymphocytes, and the activity of serum antiprotease was not affected by VC ; Serum protein concentration has a significant role in the increase; while the serum concentration of VC but significantly reduced.
