九种交配组合鳢血液生理生化指标的比较分析

Comparative study on the blood physiological and biochemical indexes of snakehead with nine mating groups

对来源于乌鳢(Channa argus)、斑鳢(C.maculate)及杂交鳢作为亲鱼彼此之间的交配繁殖得到的九种组合鳢的血液部分生理生化指标做了比较分析。其中G1—G9分别代表斑鳢(♀)×斑鳢(♂)、斑鳢(♀)×乌鳢(♂)、斑鳢(♀)×杂交鳢(♂)、乌鳢(♀)×斑鳢(♂)、乌鳢(♀)×乌鳢(♂)、乌鳢(♀)×杂交鳢(♂)、杂交鳢(♀)×斑鳢(♂)、杂交鳢(♀)×乌鳢(♂)、杂交鳢(♀)×杂交鳢(♂)。结果显示:从血液生理指标来看,红细胞计数(RBC)结果为G2>G4>G1>G5>G8>G9>G7>G6>G3,白细胞计数(WBC)结果为G2>G4>G5>G6>G1>G9>G3>G7>G8,血栓细胞计数(PLT)结果为G2>G1>G4>G5>G8>G9>G7>G6>G3,血细胞压积(HCT)的结果为G2>G1>G4>G5>G8>G9>G7>G3>G6,血红蛋白(HGB)的结果为G2>G1>G4>G5>G8>G9>G6>G7>G3,平均红细胞蛋白含量(MCH)的结果为G4>G5>G2>G1>G6>G8>G9>G7>G3,平均红细胞蛋白浓度(MCHC)的结果为G4>G5>G2>G1>G6>G8>G3>G9>G7,红细胞平均体积(MCV)和红细胞分布宽度(RDW-CV)无显著差异。从血液生化指标来看,总蛋白(TP)的大小为G5>G4>G2>G1>G6>G3>G7>G8>G9,谷草转氨酶(AST)的大小为G2>G4>G1>G5>G3>G6>G7>G8>G9,甘油三酯(TG)的大小为G5>G1>G2>G4>G3>G6>G7>G8>G9,胆固醇(CHOL)和谷丙转氨酶(ALT)无显著差异。综合分析九种交配组合鳢的血液生理及生化指标可以看出,G2(斑鳢(♀)×乌鳢(♂))和G4(乌鳢(♀)×斑鳢(♂))相对于其他的组合有明显的"杂种优势"。

The blood physiological and biochemical indexes of nine groups snakehead which came from mating with each other of Channa argus, C.maculate and hybrid snakehead, were determined and comparative studied. GI-G9 represented C. maculate （♀）×C.maculate （♂）, C. maculate （♀）×C.argus （♂）, C.maculate （♀）×hybrid snakehead （♂）, C. argus（♀）×C.maculate（♂）, C.argus（♀）×C.argus（♂）, C.argus（♀）×hybrid snakehead（♂）, hybrid snakehead（♀）× C.Maculate （♂） , hybrid snakehead（♀）× C.argus （♂） and hybrid snakehead （♀）×hybrid snakehead（♂）. Results from blood physiological indexes were as follows, RBC was G2 〉 G1 〉 G4 〉 G5 〉 G8 〉 G9 〉 G7 〉G6〉G3, WBCwasG2〉G4〉G5〉G6〉GI〉G9〉 G3〉G7〉G8, PLTwasG2〉G1〉G4〉G5〉G8〉G9〉G7〉G6 〉G3, HCTwasG2〉GI 〉G4〉G5〉 G8〉G9〉G7〉G3〉G6, HGBwasG2〉G1〉G4〉G5〉G8〉G9〉G6〉G7〉 G3, MCHwasG4〉G5〉G2〉G1〉G6〉G8〉G9〉G7〉G3, MCHCwasG4〉G5〉G2〉G1〉G6〉G8〉G3〉 G9〉 G7, MCV and RDW-CV had no difference. Results from the blood biochemical indexes were as follows, TP was G5 〉G4〉G2〉G1〉G6〉G3〉G7〉G8〉G9, ASTwasG2〉G4〉G1〉G5〉G3〉G6〉G7〉G8〉G9, TGwas G5〉G1〉G2〉G4〉G3〉 G6 〉 G7〉 G8 〉G9, CHOL and ALT had no difference. Comprehensive analysis of the blood physiological and biochemical indexes of snakehead with nine mating groups indicated that the G2（C.maculate （♀）×C. argus （♂）） and G4（C.argus（♀）×C.maculate（♂）） had the ＂heterosis＂ comparing to the other groups.
