摘要
本研究将母鸡躯体固定后，使鸡头侧、尾侧、右侧、左侧分别朝向人工磁场Ｎ极方向下饲养：（１）除头侧向Ｎ极组外，其它朝向对原条起始位置有显著和极显著的影响；（２）原条起始位置随Ｎ极移动而移动，起始于Ｎ极处的原条显著高于Ｓ极处的原条．
In this study,the hens head,right flanks,letf flanks and tails,were directed to North pole on the artificial magnetic field separately.Then,the birds were fed,fertiliaed by AI and in egg_production under the above condition.The origin of chicken embryonic shield was also observed.The results showed as following:1) The origin of chickens embryonic shield in all those experimental groups was influenced markedly or very markedly,except for that of the hens head group,2) The origin of shield moved with the direction of North pole.The origin with N pole was significantly higher than that with S pole.
