Abstract

The fiber diameter is one of the most important characteristics to aggregate value to wool production. Wishing to determine the effect of ovarian ablation on the wool characteristics, twenty four puberal Ideal ewe lambs were randomly distributed in two experimental groups. The group 1 (n=12) was submitted to surgical castration while the group 2 (control) was left intact. The wool thickness was measured one year latter in both groups. Nine castrated and four intact ewe lambs had the wool diameter lesser than 25 mm (P<0.05). Also, the mean wool diameter was significantly different (P<0.05) between castrated (24.1 ± 0.22 mm) and control (25.5 ± 0.49 mm) groups. It was concluded that the ovariectomy affect the wool structure in most of puberal ewes reducing the fiber diameter and consequently increasing the wool quality.
