چکیده مقاله :

This study was conducted to investigate the hair production and fleece characteristics of hair goats in Fars province. The material of the study included a total data of 84 hair goats, which were between kids and adult in male and female goats, respectively. The overall average for fleece weight, fiber length, staple lengths, washing yield, hair fiber diameter, of fiber diameter, breaking force, tenacity and elongation were 293.3±20.5 g, 5.5±0.3cm, 8.0±0.5cm, 73.8±0.5%, 81.0±1.9 um, 20.3±0.5%, 7.8±0.4kgf, 9.5±0.4 gf/tex and 3.5±0.2%, respectively. It was found that the effect of sex on the hair traits except fleece weight was not statistically significant (P>0.01), whereas the difference between males and females on the fleece weight was significant. Fleece weights in males and females were 331.7±29.8 and 237.4±25.7 g, respectively. However, significant difference (P<0.01) was found in fleece weight, hair length, hair diameter and tenacity between two age groups except for washing yield, coefficient of variation CV of hair diameter and hair elongation. Adult goats had more fleece weight, fiber diameter, fiber lengths, staple length, breaking force and breaking tenacity than those of kids.
