Traditionally goats are indeed important in Iran especially for milk and fibers. This country has nearly 5000000 cashmere producing goat, which produce approximately 1500 metric ton of raw cashmere. So research on environmental factors which have effect on cashmere production, is very vital to economy of the country. Raeini breed is the most productive Cashmere goat in Iran. However, There are no detailed descriptions of the effects of nutrition on cashmere characteristics in Raeini goat. There is some debate on the effects of nutrition on cashmere growth. In some studies cashmere growth does not respond to increased feed intake above maintenance. While some reviewers have concluded that nutrition does influence cashmere growth (McGregor, 1998). The objective of this study was to describe the effects of feeding level on the cashmere growth of Raeini female goats at two different ages.
