| 摘要: |
| 通过投喂添加β-胡萝卜素质量比分别为50,100 mg/kg的实验饲料,饲养中华绒螯蟹(Eriocheir sinensis)60 d,探讨了对中华绒螯蟹卵巢发育及免疫学指标的影响。结果表明,β-胡萝卜素能够明显增加中华绒螯蟹的质量,提高养殖成活率;极显著提高中华绒螯蟹血细胞 吞噬百分率(P<0.01);显著或极显著降低血清超氧化物歧化酶活力(P<0.05或P<0.01);极显著增加卵巢中总类胡萝卜素 的含量(P<0.01);显著增加肝胰腺中总类胡萝卜素的含量(P<0.05);较明显增加中华绒螯蟹卵巢指数和卵母细胞直径,但对于肝胰腺 指数、卵巢和肝胰腺蛋白质影响较小。 |

| The effect of β-carotene on ovary development and immunological parameters of Eriocheir sinensis |

| Abstract: |
| The study was conducted to determine the effects of β-carotene on ovary and immunological parameters of Eriocheir sinensis after a 60-day feeding trial. The experimental dietary levels of β-carotene were 50, 100 mg/kg. The result showed that β-carotene could increase weight of E. sinensis obviously， raise the survival rate, improve significantly the phagocytic percentage of blood cells of E. sinensis(P<0.01), decline significantly superoxide dismutase(SOD) activities in serum(P<0.05or P<0.01), increase significantly total carotenoids in ovary(P<0.01), increase significantly total carotenoids in hepatopancrea(P<0.05), increase ovary index and oocyte diameter more obviously. But it had less influence on hepatopancrea index, ovary and hepatopancrea protein. |
