| Abstract | ||
| An experiment was conducted for a period of 9 wks. to investigate the effect of adding some antioxidants to diet contain fatty acids on growth performance, some physiological and hematological parameters as well as evaluating the carcass characteristics of Silver Montazah male chicks. For this purpose 315 five-weeks old Silver Montazah (SM) males were used up to 14 wks. of age. All chicks were randomly divided into seven equal groups (45 chicks, each) with three replicates (15 chicks each). Chicks were wing banded and individually weighed, with nearly similar average initial live body weight of all groups. The 1st group was fed the basal diet that containedLinoleic acid (n-6) and Linolenic acid (n-3) at the ratio of 4:1, respectively and served as control. The 2nd and 3rd groups were fed the basal control diet supplemented with 125 and 250g Butylated Hydroxy Toluene/Ton diet, respectively. The 4th and 5th groups were fed the basal control diet supplemented with 100 and 200g vit. E /Ton diet, respectively. The 6th and 7th groups were fed the basal control diet supplemented with 5 and 10kg citric acid /Ton diet, respectively. Results indicated that dietary antioxidants supplementation especially citric acid at the two studied levels and vit. E (200 g/Ton) significantly (P≤0.01) increased live body weight at 9 and 14 wks. of age, body weight gain during the periods of 5-9 and 5-14 wks. of age, and improved feed conversion ratio during the periods of 5-9 and 5-14 wks of age compared to the control group. Moreover, significant increases were obtained for red blood cells (RBC’s) and plasma total protein and globulin concentrations for groups fed diet supplemented with antioxidants compared with the control group. Conversely, significant lower heterophils/ lymphocytes ratio and plasma concentration of total lipid, cholesterol and triglycerides were associated with supplemental antioxidants. Relative weights of liver and spleen of SM males were increased with antioxidants supplementation. In conclusion, for attaining the goal of economic improvement of meat production from local strain of chicken (SM) in Egypt. Dietary supplemental of antioxidants to feed containing fatty acids is practical application especially by 5 and 10kg citric acid and 200g vit. E /Ton diet to SM male chicks, could promoted the growth performance and had beneficial effects on some physiological and hematological parameters, as well as adjusted the carcass characteristics and immune status. | ||
