Effect Of Pomegranate And Orange Oils Supplementing As Antioxidant On Productive And Physiological Performance Of Aged Developed Chickens

This study was conducted to investigate the effects of dietary Pomegranate oil and Orange oil supplementation on egg production traits, semen quality and blood constituents of Golden Montazah (Egyptian local developed strain) laying hens. A total number of 270 laying hens + 27 cock, 52 weeks old were randomly taken to be similar inbodyweights(1440.70 ±2.23), which were randomly divided into nine experimental groups, (30 hens + 3 cocks in each). Each group was contained three replicates (10 hens+1 cock in each). The first group was fed the basal diet as control group (without any supplementation), the second and third groups were fed the basal diet and supplemented with Pomegranate seed oil (PO) levels (150 or 300 ml /kg diet), the fourth and five groups were supplemented with Orange oil (OO) levels (150 or 300 ml /kg diet), the six group was supplemented with (150 ml PO +150 OO /kg diet), the seven group was supplemented with (150 ml PO +300 OO /kg diet), the eat group was supplemented with (300 ml PO +150 OO /kg diet) and the seven group was supplemented with (300 ml PO +300 OO /kg diet), respectively, during the experimental periods lasted three months from 52 to 64 weeks of age. The obtained results showed that supplementing with either pomegranate or orange oil levels or mixtures improved significantly (P<0.01) in body weight change (BWC, %); egg production (EP, %); egg mass (EM, g) and feed conversion ratio (FCR) as g feed /g eggs when compared to hens control group, during period 52 at 64 weeks of age. Semen ejaculate volume, sperm motility (% ) and sperm-cell concentration (X 109/ml) of quails treated with supplemented of PO or OO and their mixtures significantly (P<0.01) increased compared with the other treatment groups, while dead spermatozoa (%), sperm abnormalities (%) and acrosomal damage (%) of layer treated with PO or OO and their mixtures significantly (P<0.01) decreased compared with the control group. Concerning the effect of supplementation either pomegranate or orange oil levels or mixtures in layer diets caused to increase significantly (P<0.01) in serum albumen, globulin, total antioxidant capacity, GPX, SOD, testosterone and decreased serum cholesterol compared to control group. Conclusively, supplemented layer diets with Pomegranate oil or Orange oil at level of 300 ml/ kg diet was more effective for improving productive performance traits, biochemical, immunological blood parameters and Semen quality of Golden Montazah laying hens.
