He－Ne激光提高蛋鸡产蛋率影响的研究

The effects of He-Ne laser irradiation on improving laying ability of hens

以输出功率为１３毫瓦的８４－２型兽用Ｈｅ－Ｎｅ激光治疗机扫描照射蛋鸡的内眼角和鸡冠部．每只鸡辐射１０秒钟，连续照射１０天，观察５周。结果表明，Ｈｅ－Ｎｅ激光对提高蛋鸡产蛋率，增加平均蛋重，减少破蛋率和软壳蛋率均有明显效果，可以在养鸡生产中作较大批量的观察。

Model 84-2 Veterinery He-Ne laser therapy apparatus was used for scanning the spots of internalcanthus and crown of the hens for 10 seconds lasted for 10 days with the power of 3 mw.The later 5 weeks'observation showed that He-Ne laser irradiation had significant effects in improving egg production arid average egg weight.and could also decrease broken-egg rate and soft-shelled egg rate. More experiments in this field should bemade in poultry production.
