摘要
为研究控制光周期对绒山羊绒毛生长相关激素的影响,从短光照试验和对照组绒山羊中选择2周岁6对双胞胎绒山羊母羊,采集血液样品利用酶联免疫法进行激素含量测定,利用SAS9.0软件进行显著性检验和相关性分析。结果发现:一天24h当中,绒山羊进入棚圈后褪黑激素MLT(melatonin,mLT)和IGF-1含量显著增加,PRL含量显著减少,EGF和GH含量在2组中差异不显著;一年当中,进入光控棚圈后6月份绒山羊血液中的MLT(P<0.05)、IGF-1和EGF(P>0.05)含量均增加,PRL含量显著降低;9月份试验组绒山羊MLT、IGF-1和GH含量高于对照组(P<0.05),PRL含量依然低于对照组(P>0.05)。在相关性分析中,试验组和对照组PRL与其他激素之间的相关系数为负数;与对照组相比短光照明显增加了MLT与PRL、EGF,PRL与IGF-1、EGF、GH,IGF-1与EGF、GH,EGF与GH之间的相互作用(P>0.05),减弱了MLT与IGF-1、GH之间的相互作用。结果表明,短光照通过增强各激素间的协同或拮抗作用而提前诱发绒毛生长。
To investigate the effect of short photoperiod on hormones that related to hair growth in Inner Mongolia(Arbas type)Cashmere goat,six pairs of 2-year-old twins ewes were selected from the short photoperiod and control group.The blood samples were collected and content of hormones were determined by enzyme-linked immunoassay.SAS9.0 software was adopted to conduct significant test and correlation analysis.The results showed that the content of MLT and IGF-1 was significantly increased,the content of PRL was significantly decreased,and the content of EGF and GH was not significant different between the two groups under short photoperiod in a day.In a year,the content of MLT(P<0.05),IGF-1 and EGF(P>0.05)was increased,and the content of PRL(P<0.05)was significantly decreased under short photoperiod in June.The content of MLT,IGF-1 and GH was significantly higher(P<0.05),and the content of PRL was lower in the experimental group than in the control group,in September.The correlation between PRL and other hormones in both groups was negative.Compared with the control group,interactions between MLT and PRL/EGF,between PRL and IGF-1/EGF/GH,between IGF-1 and EGF/GH,between EGF and GH(P>0.05)were increased,and interactions between MLT and IGF-1/GH were decreased under short photoperiod.In conclusion,the short photoperiod might enhance hair growth by synergistic and antagonistic effect of hormones that related to hair growth.
