Abstract

Iran is one of the major producers of cashmere fibre in the world. Considerable amount of cashmere fibre is lost as a result of seasonal shedding. Cashmere and hair of the Iranian Raeini cashmere goat grows in a distinctly seasonal pattern. Zare et al. 1999 in a study using thirthy four female and male RAEINI GOATs of 1 to 4 years old kept in a breeding station in Kerman province indicated that 30 percent of secondary follicles stopped producing fibre during mid-winter. However the extent of fibre loss in commercial Cashmere producing flocks in not known. The present experiment was conducted to determine the extent of Cashmere shedding and some fibre and follicle characteristics of RAEINI GOATs run in four different commercial flocks in Kerman province, south of Iran (29017' S). All goats were grazed on pastures throughout the year and were supplemented with hay and barley during the winter. Follicle activity and fibre characteristics of ninety six male and female goats of one to four years old (12 goats in each group) were measured. At the peak of fibre shedding season in mid-winter, skin samples were taken from the right midside region of each goat using a 1 cm diameter trephine. The samples were placed in individual cassettes and dehydrated through a series of graded ethanols and cleared in histoclear using a tissue processor. Processed skin samples were blocked in paraffin and sectioned transverse to the follicles at 8mm using a base sledge microtome. To determine the SIP ratio, 400 follicles from at least 1015 randomly selected follicle groups were counted. The percentage of active and inactive follicles was determined from the cross section of skin samples as described by Nixon (1993).To measure fibre diameter, about 15 of wool was take from the midside region of each goat and washed. The mean fibre diameter of the washed samples was measured using microprojectina. Analysis of variance was performed using the SAS computer package and the means and standard errors of the means were generated with this program. Duncan's new multiple range test was then used to compare the characteristics between groups. The average percentage of inactive secondary follicles of 1 to 4 years old male and female goats was respectively 23.44±3.50, 26.22±2.90, 24.22±3.30, 25.34±4.41, 27.35±3.65, 24.12±2.80, 26.14±3.28 and 25.61±3.43. The SIP ratio of 1 to 4 years old male and female goats was respectively 14.12±1.40, 12.45±1.70, 13.95±2.03, 12.83±1.51, 12.52±1.72, 11.98±2.1 0, 12.64±1.40 and 13.43±1.56. There were no significant difference in the average percentage of inactive follicles and SIP ratio of groups. However significant difference was found in the average fibre diameter of groups. One year old male and female goats had the lowest fibre diameter. The average fibre diameter of 1 to 4 years old male and female goats was respectively 20.85±1.21.22±1.70, 21.30±2.41, 21.45±2.12, 20.95±1.30, 21.42±1.90, 21.35±2.43 and 21.80±2.51 mm.
