This study was done to investigate the effect of pomegranate peel extract on growth performance, blood biochemical indices, intestinal morphology and meat quality of broiler fed diet-contained soybean oil. 120 male broilers were used in the form of a completely randomized design with 3 treatments, 4 repetitions and 10 chicks. Experimental diets were three levels of zero, 300 and 600 mg/kg of pomegranate peel extract (PPE). Pomegranate peel extract had no effect on performance traits including feed intake, body weight and feed conversion ratio at starter and finisher phases, but in the grower period, the levels of 300 and 600 PPE reduced feed intake (from 928 to 777 g) and feed conversion ratio (from 1.77 to 1.31; P <0.05) compare to control. The breast percentage increased from 19.78 in control to 21.95 at the level of 600 PPE and the percentage of abdominal fat decreased from 1.93 in control to 1.27 at the level of 600 PPE (P <0.05). The PPE at levels of 600 reduced concentration of cholesterol (183.68 to 137.15 mg/dl) and LDL (95.63 to 32.93 mg/dl) and the enzyme activity of aspartate dehydrogenase (263.8 to 204.28) compare to control. The villus height (from 1026.88 to 1155.12) and the villus height to crypt depth ratio (5.04 to 5.6) were higher at the 600 PPE compared to the control. The concentration of Malondialdehyde in meat decreased at 15 and 30 days after slaughter with an increase in PPE compared to control.

The aim of this study was conducted to evaluate the effects of processed pomegranate pulp with Hydroxide Calcium on performance egg quality and cholesterol, blood biochemical parameters and antioxidant status of laying hens in peak production of laying hens. A total 200 Hy-Line W-36 at peak production with 32 weeks. The dietary treatments were included the levels of 0, 4, 7 and 10 % of processed pomegranate pulp with Hydroxide Calcium. The performance data including egg percentage, feed intake, egg mass, and FCR were weekly recorded. The results were revealed that processed pomegranate pulp with Hydroxide Calcium(PPP) improved the egg percentage, feed intake, egg mass, and FCR. The egg quality parameters did not affected by dietary treatments with exception that Haugh unit increased in birds received the processed pomegranate pulp. The eggshell parameters involved eggshell weight and specific gravity had no affected by dietary treatments. The eggshell thickness and eggshell resistance was increased when hens fed diets contained PPP. The PPP diets decreased the egg cholesterol and blood cholesterol. The concentration of malondialdehyde decreased with enhancement of the levels PPP in diets. It is concluded that addition of pomegranate pulp with Hydroxide Calcium may be improved the performance, egg quality, and antioxidant status and cholesterol of laying hens.

This experiment was carried out to study the effect of oxidized soybean oil (OSO) against antioxidative ability of Pomegranate seeds (PS) on body antioxidant status and oxidative stress complications in periparturient Saanen goats. Blood total antioxidant capacity (TAC), Malondialdehyde (MDA) concentration, C-reactive protein (CRP), rheumatoid factor (RF) & enzyme activities were investigated three weeks pre and post-partum, through a completely randomized design with repeated measurements. Dietary treatments (T) included base diet and 4% fresh soybean oil (FSO) (T1), 4% OSO (T2), 4% OSO and 8% milled PS (T3)(DM basis). Three days after parturition similar diet was fed to all groups, to evaluation of durability of treatment effect. The blood enzyme activities of alkaline phosphatase (ALP), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT) & lactate dehydrogenase (LDH), CRP, RF, MDA and TAC had ascending pattern in T2 vs. T1 and descending trend in T3 vs. T2. The ascending pattern in CRP, ALT, MDA and ALP and the descending trend in RF, TAS, CRP and ALP were significant statistically. Also two weeks after feeding similar diet, all parameters except CK, RF, TAC & MDA changed likewise previous pattern. Generally, the possible roles of lipid peroxidation derivatives of OSO led to progressive oxidative stress complications and reduced Blood TAC vs. FSO. Nevertheless, PS antioxidative components had beneficial effects on blood TAC and lowering role on oxidative stress signs.
