摘  要:
为了研究不同强度光照对母鸡大脑内γ-氨基丁酸(GABA)分布的影响,试验采用免疫组化的方法,用0(黑暗环境下)、10 lx、20 lx、30 lx不同强度的光照对120日龄母鸡进行光照刺激,检测GABA在大脑中的表达。结果表明:大脑中有大量GABA免疫反应阳性神经元,主要见于新纹状体(N)、上纹状体腹侧(HV)、上纹状体附属部(HA)。在10 lx、20 lx光照条件下,GABA在大脑中的表达量比在0和30 lx光照条件下少,由于GABA是抑制性神经递质,表明在10~20 lx的光照条件下能提高蛋鸡生产性能。

摘  要:
To study the effect of different intensity of light on the distribution of γ- aminobutyric acid( GABA) in hen cerebrum,an immunohistochemical method was applied to detect the expression of GABA in the cerebrum after using a light stimulation with different intensity of 0,10 lx,20 lx,30 lx on 120- day- old hens. The results showed that there were a large number of GABA immunoreactive positive neurons in the cerebrum,which were mainly present in the neostriatum( N),hyperstriatum ventrale( HV),and the hyperstriatum accessorium( HA). GABA expression levels under light conditions of 10 lx and 20 lx were lower than those under light conditions of 0 and 30 lx because GABA was an inhibitory neurotransmitter. The result indicates that the productive performance of laying hens can be improved under light conditions of 10 lx and 20 lx.
