Sažetak
Twenty - four male lamb of Afshari sheep (mean live weight 35±1.21 kg, 10 month of age) were used to study the effect of different levels of dried pistachio epicarp (0, 12, 22 and 32 %) on wool characteristics. The staple length on shoulder (STS), flank (STF), back (STB) and rump (STR), true wool fiber (TW), medullated fiber (MF), kemp fiber (KF) percentage, mean wool fiber diameter (MD) and its coefficient variation (CVMD), breaking load (BL), wool tenacity (WT) and extension (E) were measured. These data were analyzed by one- way ANOVA using SAS software package. The total means of STS, STB, STF, STR, TW, MF, KF, MD, CVMD, BL, WT and E of wool were 6.06 ± 0.26, 6.60 ± 0.19, 6.23 ± 0.18 and 5.64 ± 0.18 cm, 63.74 ± 2.2, 12.36 ± 1.9 and 23.87 ± 2.1 %, 36.37 ± 0.85 mu, 46.7 ± 1.99 %, 7.06 ± 0.3 kgf, 3.2 ± 0.17 gf/tex and 33.59 ± 1.4 % respectively. Although there were no significant differences among treatments, the results showed that feeding lambs pistachio epicarp up to 32.5 percentage of total dry matter intake did not affect wool characteristics.
