摘要：This experiment was aimed to identify characteristics and comparative merits of Iranian sheep wool breeds. Fiber characteristics of 75 male and 137 female of 1, 2, 3 and 4 yr of age belonging to Afshari, Zandi, Mehrabani, Lori, and Baluchi sheep breeds were studied. Samples of fiber were taken from the left midside of sheep and analyzed using standard objective measurements for staple length (SL), mean fiber diameter (MFD), coefficient of variation of fiber diameter (FDCV), inner coat fiber ICF, outer coat fiber (OCF), kemp fiber (KF) and yield (Y). A general linear model including sex and age as fixed effects and breed as random effect was used to analyze the data. The mean (and s.e) for SL, MFD, FDCV, ICF, OCF, KF and Y were 110.8±0.1 mm, 36.9±0.5 µm, 50.2%±0.8%, 84.2%±0.6%, 9.8%±0.4%, 5.9%±0.4% and 69.3%±0.7% respectively. MFD of 22% of all wool samples was between 22-30 µm. MFD of a further 36% and 42% of wool samples was between 31-37 µm and coarser than 37 µm. SL of 12% of wool samples was shorter than 100 mm and 38% of samples between 100-120 mm and 50% of samples were longer than 120 mm. There is substantial scope to improve the quality of fiber produced by Iranian sheep breeds through genetic selection.
其他摘要：Penelitian ini bertujuan untuk mengidentifikasi karakteristik dan membandingkan keunggulan domba tipe wool Iran. Karakteristik serat dari 75 ekor jantan dan 137 betina umur 1, 2, 3, dan 4 tahun bangsa domba Afshari, Zandi, Mehrabani, Lori, dan Baluchi diamati pada penelitian ini. Sampel serat diperoleh dari sisi tengah kiri domba dan dianalisa menggunakan pengukuran secara objektif untuk panjang serabut (SL), diameter serat tengah (MFD), koefisien keragaman diameter serat (FDCV), serat lapisan dalam (ICF), serat lapisan luar (OCF), serat kemp (KF), dan perolehan serat (Y). Nilai tengah (dan standar error) untuk SL, MFD, FDCV, ICF, OCF, KF, dan Y secara berurutan adalah 110,8±0,1 mm, 36,9±0,5 µm; 50,2%±0,8%; 84,2%±0,6%; 9,8%±0,4%; 5,9%±0,4%; dan 69,3%±0,7%. MFD 22% dari seluruh sampel wol adalah 22-30 µm. MFD 36% dari sampel wol adalah antara 31–37 µm dan 42% lebih dari 37 µm. SL dari 12% sampel wol lebih pendek dari 100 mm, 38% sampel antara 100-120 mm, dan 50% sampel lebih panjang dari 120 mm. Karakteristik tersebut merupakan lingkup penting untuk meningkatkan kualitas serat yang dihasilkan bangsa-bangsa domba Iran melalui seleksi genetik.
