STUDY OF THE EFFECT OF BODY WEIGHT AND PHYSIOLOGICAL STATUS ON WOOL YEILD AND TRAITUS FOR THE EARLY MATING OF AWASSI EWES

Abstract

This study was conducted at Animal Resources Department at College of Agriculture and Forestry –Mosul University, on 54 Awassi female lambs aged 3-4 months, they were mated early by 8-9 months, and lambing began by 13-14 months for Knowledge the influences of body weight & Physiological status on wool yield & traits . Samples of wool were taken at 1.5 year of age . The results revealed significant effect (p≤0.05) for the three weight classes on all wool traits studies. The physiological status of ewes effect significant (p≤0.05) greasy fleece weight (GFW),clean fleece weight (CFW) & fiber length (FL). There was a significant effect(p≤0.05) for suckling status on(GFW) , (CFW) & (FL) . There were a highly significant (p≤0.01) correlation between (GFW) & both of (CFW) and fiber diameter (FD) 0.945 & 0.194 respectively ,significant correlation (p≤0.05) between (GFW) & clean wool percentage (CW) 0.115 . There were a highly significant (p≤0.01) correlation between (CFW) & both of (CW) & (FD) 0.309 and 0.191 respectively , and a highly significant correlation between (CW) & both of staple length (SL) & (FL) 0.241 & 0.208 respectively , with a highly significant correlation (p≤0.01) between (SL) & (FL) 0.939 , & between (FL) &(FD) 0.860 .
