去势对公鸡血常规及血液性激素水平的影响

为研究去势对公鸡激素及其血常规指标的影响,采用日本SYSMEX-XS-800i血细胞分析仪和γ-911全自动放免计数仪,测定白来航公鸡和寿光公鸡在早期(9周龄)和晚期(17周龄)去势前后血常规指标和血液激素含量,比较各参数种间、种内差异。结果表明:白来航公鸡和寿光公鸡中,不论是在早期(9周龄)还是晚期(17周龄)去势条件下,外周血红细胞计数、血红蛋白、红细胞压积和红细胞平均血红蛋白浓度均是对照组极显著高于去势组(P<0.01);在早期去势条件下,2个品种公鸡血清中雌激素(E2)含量,去势组均显著高于对照组(P<0.05);无论在早期还是晚期去势条件下,2个品种公鸡血清中雄激素(T)的含量,对照组均极显著高于去势组(P<0.01);对比同周龄去势的白来航公鸡和寿光公鸡,除雄激素在早期(9周龄)去势阶段的对照和去势组,以及晚期(17周龄)去势阶段的对照组中,白来航公鸡显著高于寿光公鸡(P<0.05)外,其他各项指标不存在显著差异。上述结果表明,阉割会引起公鸡血常规参数和激素含量常值的改变,从而可能影响公鸡个体表型上的改变。

Effects of castration on blood routine tests results and hormone levels in roosters

The purpose of this study was to investigate the effects of castration on blood routine tests results and hormone level in white Leghorn and Shouguang roosters using the SYSMEX-XS-800i hematology analyzer and r-911 automatic RIA counter.roosters.The results show that,castration significantly decreases peripheral red blood cell count,hemoglobin,testosterone (T) concentrations,hematocrit and mean corpuscular hemoglobin concentration for both white Leghorn roosters or Shouguang roosters regardless castration at 9 wks (early) or 17 wks (late,P<0.01).On the other hand,serum estrogen (E₂) concentrations were significantly higher (P<0.05) in the early castrated roosters,compared with control groups in both species..These results indicate that castration will changed the results ofblood routine tests and hormone level in white Leghorn and Shouguang roosters,which may affect the phenotypes of the castrated roosters.
