دراسة بعض الخصائص الطبيعية لصوف أغنام البربري الليبية في منطقة وادي زمزم

Abstract

This study was conducted on local Barbary sheep raised in wadiZamzam region in the northern part of Libya, their ages ranged from 3 to 5 years, in order to study the effect of both the herd factor on the greace fleece weight and the factor of different body positions, thigh,shoulder, med-side and neck, on some physical wool traits, fiber diameter, stable and fiber length, during the shearing season April 2010.

The study results showed the herd factor had an insignificant effect on grease fleece weight, however, the different body positions  had significant differences in the studied samples, where the shoulder was significantly superior in the fiber diameter trail_ the finest fiber_ at a rate of 28.77 ± 8.07 μm ,and the thigh in the stable length trait of 9.61 ± 2.63 cm rate and the thigh and med-side  in the fiber length trait of 9.03 ± 2.51, 8.91 ± 2.80cm rate, respectively.  The general average of the traits under study was (1.50 ± 0.62 kg), (29.44 ± 8.45 μm) (8.73 ± 2.45 cm), and (08.70 ± 2.61 cm)   to the grease fleece weight ,  the fiber diameter, the stable and fiber length, respectively,

Accordingly, it is turned out that the quality of the wool traits under study differs  according to the different  body positions.
