| Abstract | ||
| The objective of this study was to determine the optimal dietary chelate of zinc and manganese on the growth performance, blood profile and carcass characteristic. A total number of 1050 unsexed quail chicks aged 7 days and averaged 23.7g body weight were divided randomly into five groups (210 birds each), each group was subdivided into three replicates, each with 70 birds. Birds were kept under the same administrative, healthy and environmental conditions The five treatment groups were fed as follows: The 1st group of birds was fed basal diet and served as control (T1), birds of the 2nd and 3rd groups were fed the same basal diet supplemented with 100 mg zinc tryptophan chelate (T2) and 100 mg zinc proteinate chelate (T3). While birds from the 4th and 5th groups were fed the same diets of control diet supplemented with 100 mg manganese tryptophan chelate (T4) and100 mg manganese proteinate chelate (T5). Feed and water were provided ad libitum throughout the experimental period. The trial lasted 5 weeks. The results indicated that body weight gain and feed conversion coefficient were influenced by supplemental levels of zinc and manganese proteinate chelates, the hemoglobin concentration, packed cell volume and white blood cell were significantly higher in groups T3 and T5. Total cholesterol level, LDL-cholestrol and glucose decreased in T3and T5 treatment ( Zn and Mn proteinate chelate). However, HDL-cholestrol level, Albumin, AST, ALT, ALP and calcium were significantly increase with chelated minerals treatments. The effect of treatment on the carcass traits and relative weight of the lymphoid organs were significantly increased. It is concluded that supplementing diets of Japanese quail with Mn and Zn chelate especially with protein had great influence on performance, blood profile and carcass characteristics as well as improved the immune response | ||
