Effect Biological lupine Albus on some wool physiological traits of Awassi Lambs

Back Ground: The study was conducted in the field of animal production - College of Agriculture / University of Tikrit for the period from 15/2/2017 to 15/5/2017. Objective: to study the effect of replacing the seeds of white Lupinus albus  as a protein source instead of soybean meal and its effect on some characteristics of wool: (softness  , elongation, tensile strength, raw weight and clean weight) at the age of (4 and 6) months, respectively, for the mentioned characteristics, and the quality of wool fibers is the basis of characteristics and defects, as the fiber diameter is the main determinant of quality. Materials and Methods: The experiment was conducted by raising twelve Awassi lambs, 4 months old, with an average starting weight of 24.65 ± 2.49 kg. The lambs were distributed among 3 treatments (4 lambs/treatment). At levels (0, 6 and 12%) for the first treatment (control), the second and the third, respectively. Results: After completing the experiment using white lupine seeds, the results indicated that there were no significant differences between the studied traits (softness, tensile strength, raw weight and clean weight) at the age of (4 and 6) months, respectively, except for the second treatment (6% lupine), which was significantly superior (0.05).  > P) In terms of elongation at the age of 6 months (65.25 ± 1.92) compared to the first and second treatments (0 and 12) % lupine, respectively. Conclusion: I used a balanced diet in its content of energy and protein and added a protein source (white lupine seeds) instead of soy beans and did not occur any negative changes that affected the qualities of wool, and this means the positive use of it in feeding ruminan
