The objective of the current study was to evaluate the effects of a commercial prebiotic (Bio-Mos®) feed additive as a growth promoter on growth performance and some growth-related hormones of Japanesequail. A total number of 480 one day old Japanese quail chicks were randomly allocated into 4 equal groups. Group 1(control group) fed on the basal diet that did not supplemented with prebiotic, group 2 fed on basal diet with 0.5 gm Bio Mos/kg diet, group 3 fed on basal diet with 1gm Bio Mos /kg diet and group 4 fed on basal diet with 2 gm Bio Mos /kg diet.To evaluate growth parameters, 30 birds from each group were weighed weekly for eight successive weeks. Feed consumption per group was measured weekly for calculating feed conversion ratio. Blood samples were collected weekly from six birds from each group, and then plasma was separated for evaluation of insulin concentrations. At the end of the experiment, The results of the current study revealed that, addition of Bio Mos to Japanese quail ration resulted in improvement of growth parameters (Body weight, weight gain, RGR) when compared with control group. Plasma insulin concentrations in treated groups showed significant differences when compared with control group. |
