摘要
[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(P<0.05);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(P>0.05)。[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。
[Objective] To evaluate the application effect of a cashmere production improvement technology by photoperiod control in different local varieties of Mongolian colored cashmere goats. [Methods] Seven local varieties of colored cashmere goats were selected from five provinces of Mongolia. Goats of the same variety from the same region were assigned to experimental group and control group. The experimental groups were reared according to a patent technology of cashmere production improvement. The thickness, yield and fineness of cashmere of goats in experimental group and control group for each variety were determined and statistically assessed. [Results] From 2015 to 2017, for all of the seven selected local varieties of Mongolian colored cashmere goats, the experimental groups showed significantly higher cashmere thickness and yield compared to the control groups （P〈 0.05）; in 2017, for the three tested varieties, no significant differences in cashmere fineness between experimental groups and control groups were found （P〉0.05）. [Conclusion] The technology evaluated in this study has a significant cashmere production improvement effect on Mongolian colored （Red and black） cashmere goats, furthermore, it has no affect on their cashmere fineness.
