Effect of Vitamin C, Red Pepper and Oak Leaves on Physiological and Productive Performance of Quail
ABSTRACT: The current study was conducted on the animal production college of agriculture and forestry-University of Duhok, in order to investigate the effect of ration supplementation with vitamin C, red pepper (RP) and oak leaves (OL) on some physiological, reproductive and productive parameters of quail. Four hundred eighty quail birds (7 days) were divided into four groups with three replicates / group (40 birds/replicate, the groups were treated from the age of 7 days till the age of 49 days as follows: T1 (control): Reread on standard ration, T2: Reread on standard ration supplemented with vitamin C(300mg /kg ration). T3: Reread on standard ration supplemented with red pepper crush (5g/kg ration). T4: Reread on standard ration supplemented with oak leaves crush (10g/kg ration).The results of the current study revealed the following: Significant increase in live body weight (LBW) and body weight gain (BWG) of treatment as compared with control, significant decrease in feed consumption (FC) in vit. C group as compared with control, a significant improvement feed conversion ratio (FCR) in OL group as compared with control and in RP and vit. C groups as compared with OL group, a significant decrease in carcass weight of RP group as compared with control and OL groups and in heart relative weight as compared with vit. C group. Significant increase in mean egg weight, hen day (HD) % and egg mass/hen in OL group as compared with control and in as compared with other treatments. Significant increase in serum total protein (TP) and globulin in OL group as compared with vit. C group and a significant decrease in serum albumin in RP group as compared with control of male quail and a significant decrease in serum TP, globulin, albumin and TG in all groups as compared with control of female quail, a significant decrease in Cholesterol in OL group compared with control and in glucose as compared with RP and vit. C groups. Significant improvement in Lymphocyt (L)%, Heterophil (H)% and stress index in OL group of female quail and in L% and in H% in vit. C group of male quail significant improvement in yolk index in OL group and in shell membrane thickness in control group.
