摘要:

光控增绒即利用增绒专用棚圈控制光照强弱与时间长短,刺激产绒动物松果体增加褪黑激素的分泌,进而使绒山羊在非产绒季节产绒的技术。本试验通过对内蒙古阿尔巴斯型绒山羊进行光控增绒处理,研究非产绒季节光控增绒技术对绒山羊产绒性能的影响。将66只2周岁母羊随机分为控制光照增绒试验组和自然光照放牧对照组,每组33只,每月按时称量体重并采集绒毛混合样,分析试验期间绒伸直长度、细度、产绒量等产绒性状及体重的变化。试验结果表明,经光控增绒之后对照组和试验组羊绒平均细度无明显差异(P>0.05);试验期间对照组山羊羊绒伸直长度为3.20 cm,试验组为7.85 cm,两组间差异显著(P<0.05);试验组山羊平均产绒量比对照组高56.5%~68.2%,差异极显著(P<0.01);光控增绒前后,两组绒山羊体重差异均不显著(P>0.05)。综合试验结果,非生绒期通过光控增绒可促进羊绒生长,显著提高了个体产绒量;绒纤维长度增加,但绒细度没有明显变化。

Abstract:

The technology of increasing cashmere by light control in which special housing was used to control light intensity and the length of time,was to stimulate the pineal gland to increase the secretion of melatonin,which make goat producing cashmere in the non-cashmere producing seasons.The influence of light control on the production performance of cashmere goats was studied in Inner Mongolia Arbas cashmere goats in the non-producing seasons.66 ewes aged 2-year old were randomly divided into the artificial lighting control group (experimental group) and the nature light group (control group),with 33 goats per group.All the goats were weighted and the cashmere samples were collected every month,and the straighted length,fineness,yield of cashmere and body weight changes were analysized.The results showed that the average of fineness of the cashmere in two groups had no significant difference (P>0.05);The length of cashmere in control and experimental groups were 3.20 and 7.85 cm respectively during the experiment period,which had significant difference (P<0.05);The average yield of cashmere in the experimental group was increased by 56.5%~68.2% comparing with control group (P<0.01).The body weights of control and the experimental groups had no significant difference (P>0.05).In conclusion,the cashmere production was promoted by light control during the non-cashmere producing seasons,the individual yield of cashmere increased,the length of cashmere increased,but the fineness of cashmere had no significant change.

Key words: increasing cashmere by light control; Inner Mongolian Arbas cashmere goat; non-cashmere producing season; cashmere production performance
