控光增绒技术在辽宁绒山羊中应用效果观察

摘要

2010～2012年，辽宁省畜牧科学研究院先后在本院科技示范场、凤城市绒山羊养殖户，开展了辽宁绒山羊控光增绒试验，设置了不同控光时间的试验组以及相应的对照组，以期验证该项技术在辽宁地区和辽宁绒山羊生产中的应用效果。试验结果表明，该项技术对辽宁绒山羊增绒效果不明显，达不到一年两次剪绒、提高产绒量的目的，建议谨慎将该项技术应用于辽宁地区辽宁绒山羊生产中。%Two series of experiments on light control for cashmere production tech-nology were carried out in technology demonstration farm and Fengcheng cashmere farm during 2010 to 2012. The animals were divided into four groups according to the time of light control for and another control group, the result showed that no sig-nificant positive effects on cashmere production. Consequently, the promotion and application of the light control technology in Liaoning Cashmere Goat should be cau-tious.
