Effect of using different levels of flaxseed on physiological performance in Awassi Turkish ewes


This study was conducted at the sheep farm, College of Agriculture, University of Baghdad, Department of Animal Resource, from 11/6/2014 – 23/12/20014. To investigate the effect of using different levels of dietary flaxseed on physiological performance of Awassi Turkish ewes. Thirty Turkish Awassi ewes, weighting 30-59 kg live weight and 2-2.5 years old, were randomly and equally divided into 3 groups (10 ewes each). The first group was considered T1 as control group (without flaxseed %), the 2nd group (T2) was supplemented 2% flaxseed, and the 3rd group (T3) was supplemented with 4% flaxseed. Blood sample were collection in one day monthly through experiment. Results indicated significant (P<0.01) increased of glucose concentration in T3 (136.98 mg/dl) compared with T2 and T1 group, 130.65, 114.84 mg/ dl respectively. Supplemented 4% flaxseed for dietary ewes significant increased (P < 0.01) in cholesterol concentration (117.87 mg/ dl), compared with T2 and control group (111.27, 83.68 mg/ dl) respectively. There was a highly significant (P< 0.05) in progesterone concentration in T2 and T3 group 4.17, 3.95 ng/dl respectively. Compared with T1 3.57 ng/dl. There was no significant effect of flaxseed on triglycerides concentration it was 19.67, 17.85 mg/ ml respectively compared with T1 17.88 mg/ ml. There was no significant effects of supplemented flaxseed on total protein concentration among groups T2 and T3, 4.62, 4.66 gm/ dl respectively, compared with control group (4.33 gm/ dl). There was no significant effect of flaxseed on AST enzyme among groups T2 and T3 387.18, 370.68 U/L respectively, compared with T1 4.28.41 U/L. there was significant decreased (P<0.05) in ALT enzyme in T3 and T2 group, 18.56, 20.73 U/L respectively, compared with T1 group, 20.27 U/L. There was no significant effect of flaxseed on PCV percentage in T3 and T2 group, 30.78, 33.04% respectively, compared with T1, 31.22%. Added flaxseed in dietary ewes showed a highly (P<0.05) increased in hemoglobin concentration for T2 and T3 group (10.58, 10.10 gm/ dl) respectively, compared with T1 group (10.02 gm/ dl).
