[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] The research aimed to evaluate the application effects of light-weight increasing cashmere technology in different colored cashmere goat breeds in Mongolia. [Method] Seven colored cashmere goats were selected from 5 provinces of Mongolia. The cashmere goats were divided into experimental group and control group from the same area and the same variety. The cashmere goats’ Increasing velvet feeding method) to deal with the test group of cashmere goats, measuring and comparing the cashmere thickness, cashmere yield, fineness and other indicators of the cashmere goats in each test group and control group. [Result] The cashmere thickness and cashmere yield of the sheep in the seven varieties tested in 2015-2017 were significantly higher than those in the control group (P <0.05). The velvet fineness Compared with the control group, there was no significant difference (P> 0.05). [Conclusion] The light-control and increasing-velvet technology is suitable for the production of Mongolian colored cashmere goats (red goat and black goat breeds). The technology has the obvious effect of increasing velvet without changing the fineness of the velvet.
