Abstract
The effect of melatonin and bromocryptine on body weight, fibre shedding and cashmere traits was investigated by using 24 Raeini female goats (2-3 years old) in four experimental groups: control (C); melatonin (MI) implant (18 mg at first and repeated after 40 days), bromocryptine (B) injection, (0.5 ...

The effect of melatonin and bromocryptine on body weight, fibre shedding and cashmere traits was investigated by using 24 Raeini female goats (2-3 years old) in four experimental groups: control (C); melatonin (MI) implant (18 mg at first and repeated after 40 days), bromocryptine (B) injection, (0.5 mg/kg BW per three days) melatonin and bromocryptine implant and injection (MIB). All goats were maintained under natural photoperiodic conditioned of short day photoperiod (8 h light and 18 h dark), for two months. Fibre was harvested by using wooden combs and each goat was combed four times at two week intervals, from 23th February to 8th March. Combed fibers were 23.3, 15.7, 17.0 and 21.3 percent for MI, B and MIB treated and C groups. Cashmere fiber diameter (CFD) for MI group (21.4 um) was higher than the other C, B and MIB groups 20.2, 19.9 and 19.8 um (P<0.01). The CV of CFD was significant and higher in C group compared with the other groups (P<0.05). These results suggest that melatonin and bromocryptine improve uniformity of cashmere diameter in Raeini female goats.

To study the fleece characteristics of native goats in Sistan and Balouchestan province, fiber sample was taken from 270 females between one to three years old from Khash, Saravan and Iranshahr cities. The differences between age groups for all fleece parameters except fleece weight were not significant. The fleece weight of two and three years old goats were 263.4 (± 7.7) and 315 (± 7.8) gr, respectively and were more than the fleece weight of yearling goats 323 (± 7.7) gr. The results of cashmere in Khash goats was highest (26.3 ± 1%), and the goats of Iran-shahr had the finest cashmere of (12.5± 0.3 micron).

To study of environmental effects (sex and age) on fleece traits of dromedary camel in Sistan and Balouchestan province, 48 male and female which rose in five cities (Zahedan, Zabol, Khash, Iran-shahr and Ghabahar) belonging to three age groups (<2, 2-6 and >7 years) were measured.

To study of environmental effects (sex and age) on fleece traits of dromedary camel in Sistan and Balouchestan province, 48 male and female which rose in five cities (Zahedan, Zabol, Khash, Iran-shahr and Ghabahar) belonging to three age groups (<2, 2-6 and >7 years) were measured. Results indicated that there was not significantly different between sexes and age groups for all of fleece parameters, expect staple length of hump was effect by sex and also rump staple length and scoured yield were effect by age groups (P< 0.05). The means of shoulder, flank, rump, hump and overall four spots staple lengths were 4 (± 1.6), 2.6 (± 1.2), 2.6 (± 1.4), 4.4 (± 1.9) and 3.5 (± 0.13) cm. The means of inner coat, fiber diameter and coefficient of variation of fiber diameter, and scoured yield were 82 (± 1.07)%, 36.7 (± 1) micron, 38.8 (± 0.9)% and 74.3 (± 0.09)% res. The ranges varied of these characters were from 58.3 to 94%, 16.8 to 39.2 micron, 26.1 to 61% and 61.2 to 84.5%, respectively.
