Abstract

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
