STUDY OF THE BIOLOGICAL EFFECT OF SUBSTITUTION SOYABEAN MEAL WITH Lupinus albus ON SOME BIOCHEMICAL PARAMETERS IN AWASSI LAMBS FROM WEANING TO PUBERTY

Abstract

This study was carried out at the farm of the Animal Resources Dept. / College of Agriculture / University of Tikrit during the period from 15/2/2017 to 15/6/2017. Twelve Awassi lambs at the age of 4-5 months of age with an average weight of 24.65±2.49 kg, were distributed into 3 groups (4 lamb/group) to study the effect of replacement of soybean with Lupinus albus at levels of 0, 6 and 12% for the T1 (control),T2 and T3 respectively and its effect on some biochemical indicators including cholesterol ,HDL, LDL, total protein, albumin, globulin, AST, ALT, glucose and calcium Ca+2 concentrations for four age periods, 4-5, 5-6, 6-7 and 7-8 month for first, second, third and fourth periods respectively. The results showed significant decrease (P<0.01) in cholesterol level in T2 during the second period, while the third group showed a significant increase (P<0.01) in HDL at the first period and significant decrease (P<0.01) in LDL at the second and third periods. The level of globulin was increased significantly (P<0.01) in T2 at the second period and significant increased (P<0.01) in AST and ALT for T3 at first and second periods while serum glucose was significantly increase in T3 at the third period and Ca+2 levels was significantly increased (p<0.01) at the same period.
