摘要
通过H/L值的比较,对不同品种鸡的抗应激能力进行评价。随机抽取如皋鸡、文昌鸡以及安卡鸡各80只,分别检测了41、56、71和89日龄的异嗜性粒细胞(H)、淋巴细胞(L)及H/L值。结果表明:(1)在41、56日龄时,如皋鸡与文昌鸡、安卡鸡相比H、L及H/L值呈极显著差异(P<0.01);89日龄的H/L值在文昌鸡和安卡鸡之间呈极显著差异(P<0.01)。(2)如皋鸡在41日龄和71日龄间H、L及H/L值呈极显著差异(P<0.01),其余差异均不显著。文昌鸡H、L及H/L值在各日龄间变化较大,41和71日龄间呈显著差异(P<0.05),41和89日龄、56和71日龄以及56和89日龄间呈极显著差异(P<0.01)。安卡鸡各值只在56和89日龄间呈显著差异(P<0.05),其余差异均不显著。研究初步表明家禽的抗应激能力存在品种间差异,如皋鸡的抗应激能力优于安卡鸡,文昌鸡晚期表现出较好的抗应激能力,随着日龄的增加,品种之间的抗应激能力差异会减小。
The present study evaluated the stress resistance in different chicken breeds by H/L ratio. Random sampling of 80 chickens was taken from population of Rugao Chicken （RG）, Wenchang Chicken （WC）, and Anka Chicken （AK）, respectively. The value of Hetero- phil （H）, Lymphocyte （L） and Heterophil/Lymphocyte （H/L） at 41, 56, 71 and 89 days of age was detected. The results showed that there were extremely significant differences （P〈0. 01 ） in the H, L and H/L ratio between RG and WC, as the same as RG and AK at 41 and 56 days of age, meanwhile, the same difference in H/L ratio between WC and AK were found at 89 days of age. In the same population, the H, L and H/L ratio of RG had extremely significant differences （P〈0. 01 ） between 41 and 89 days of age. The corresponding value of WC varied significantly among different days of age, which indicated that the values presented significant differences （P〈0. 01 ） between 41 and 89, as well as between 56 and 71 or 89 days of age, and significant differences （P〈0.05） between 41 and 71 days of age. AK only showed significant difference （P〈0.05） between 56 and 89 days of age. The results demonstrated that there were differences in resistance to stress between different chicken breeds. RG chickens had better resistance to stress than AK chickens, and WC chicken ranked third. The difference of resistance to stress between different breeds might be reduced with age.
