摘　　要：通过在日粮中添加亚硒酸钠,研究不同水平无机硒对公鸡睾丸组织细胞结构的影响。选取80只体重接近、健康无疾病的海兰白成年公鸡,随机分成4组,每组20只鸡。对照组饲以基础日粮;硒处理组分别在基础日粮中添加0.5、1和2 mg/kg的亚硒酸钠。H-E染色的结果表明:0.5 mg/kg组公鸡睾丸发育最好,各级生精细胞数量最多;1 mg/kg组睾丸各级生精细胞较多,但细胞间存在明显间隙,成熟精子较少;而2 mg/kg组睾丸组织结构已经发生一定程度的损伤,各级精细胞数量都较少。试验说明,日粮添加适宜浓度的硒可促进公鸡睾丸的发育,而较高的硒添加量会使睾丸发育不良。The objective of this study was to investigate the effect of different standard sodium selenite added in diet on the testis cell structure in cocks. The result showed： The testis microscopic structure of cocks in the 0. 5 mg/kg group was better than those in other groups, and the testis cell structure in the 2 mg/kg group was the worst. This study indicated that suitable Se concentration added in diet could promote the testis development of cock, but the higher Se concentration make testis dysplasia.
