Abstract: In this paper,data from 2003 to 2011 production performance records of Inner Mongolia White Cashmere goats were used to analysis and discuss the relationship between cashmere yield and weight after fleecing (WT). Excel and SAS were used to organize data in the study. Cashmere yield decreased in 2004,2008,2009,2011 years,but WT increased. As the growthof the age, the cashmere yield gradually increased before the fourth years old, and declined but there were a few still increasing phenomenon of varying degrees after the fourth years old,WT showed an increasing trend. Ignoring year's environmental factors the cashmere yield and WT had a same trend as the growth of the age before the fourth years old, but with the increasing of cashmere yield, the increasing of WT presented decrescent trend.Otherwise, with the increasing of WT, the added of cashmere yield slowdown. While the cashmere yield increased whereas WT decreased, and cashmere yield decreased but the fleece weight increased in the same wool production season. This research showed that there were some competition between the cashmere yield and WT grew together at the same time at the post-growing period.

Key words: Inner Mongolia white cashmere goats; cashmere yield; weight after fleecing
