摘要
本试验分二期研究了环境温度对鸡直肠温度、冠温和血浆睾酮水平的影响。结果表明,鸡直肠温度和冠温与环境温度均呈正相关变化,但冠温变化幅度和个体变异明显大于直肠温度,说明冠温对环境变化比较敏感,而置肠温度在一定环境温度条件下,则能保持相对稳定。血浆睾酮水平在5~9℃低温下极显著升高(P<0.01)。
80 broiler breeding cocks were used in tho present studies to examine the effect of ambient temperature (Ta) on rectal and comb temperature and plrisma testosterone level.The results showed that rectal and comb temperature (Tr and Tc) were correlative to ambient temperature,but the changing range and individual deviation of Tc were significantly greater than those of Tr,which indicated that Tc was comparatively sensitive to Ta and Tr could be relatively stable.Plasma testosterone level increased very significantly at low Ta (P<0.01).
