This study was conducted to investigate the hair production and fleece characteristics of hairy goats according to the sex and age of animals. The material of the study consisted one total data of 73 hair goats, which were between more than one year-old and one year-old Lori goats from both sexes (26 males and 47 females). The overall fleece weight, fiber length, lock length, washing yield, hair fiber diameter, coefficient of variation f diameter, breaking load, tenacity and elongation were 429 ± 23.7 g, 6.2 ± 0.3 cm, 8.9 ± 0.4 cm, 73.9 ± 0.6%, 82.6 ± 1.8 micron, 24.3 ± 0.8%, 7.6 ± 0.3kgf, 10.2 ± 0.4 gf/Tex and 14.0 ± 1.0%, respectively. It was found that age and sex had a significant effect on fleece weight and lock length. Furthermore, fiber length, fiber diameter and coefficient of variation of fiber diameter were affected by age of Lori goats. Adults showed a tendency to present higher fiber tenacity (10.3±0.6 gf/tex) and lower fiber elongation (12.4±1.4%).
