光控增绒技术在彩色绒山羊中的应用效果研究

[目的]评价光控增绒技术在蒙古国不同彩色绒山羊品种上的应用效果。[方法]从蒙古国5个省选取7个彩色绒山羊品种,将选自相同地区、相同品种的绒山羊分为试验组和对照组,利用绒山羊光控增绒专利技术(一种绒山羊增绒的饲养方法)对试验组绒山羊进行处理,测定并比较各品种试验组和对照组绒山羊的绒厚度、绒产量、绒细度等指标。[结果]2015—2017年测定的7个品种试验组羊只的绒厚度与产绒量均显著高于对照组(P0.05);2017年测定的3个品种试验组羊只的绒细度与对照组相比无显著差异(P0.05)。[结论]光控增绒技术适用于蒙古国彩色绒山羊(红山羊和黑山羊品种)生产,该技术在不改变绒细度的前提下增绒效果显著。
