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.

This study was to investigate the effect of Portulaca oleracea L. extract(POE) on performance, carcass characteristics, immune response, blood indices and intestinal morphology in broilers under heat stress. 200 Ross 308 single-day-old chicks were used in a completely randomized design with 5 treatments, 4 replications and 10 chicks. Experimental groups were: negative control (no heat stress), four groups under heat stress (positive control), 250, 500 and 750mg of POE per kg diet. Results showed that using POE increased feed intake and body weight compared to the control (P <0.05). Chicks fed POE had lower feed conversion ratio than positive control group (P<0.05). Addition of POE to broiler diet had no effect on relative weight of carcass components including breast, thigh, spleen, bile, pancreas and abdominal fat. The POE reduced the relative weight of heart and liver compared to the positive control and the relative weight of bursa was higher in the chicks fed the POE (P<0.05). The POE increased total antibody titer against sheep red blood cells. Using the POE in broiler diet had no effect on plasma concentration albumin and protein, but the lowest concentration of cholesterol, triglyceride, LDL and highest HDL were observed broilers fed 750 POE. The activity of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase enzymes decreased during heat stress compared to negative control. POE increased villus height and absorption area compared to control(P<0.05). It is concluded that using POE reduced plasma concentration of cholesterol, LDL, and plasma MDA in broilers under heat stress.

To determine the effects of olive pulp(OP) on growth performance, nutrient digestibility, blood indices and intestinal morphology in Japanese quail, A total of 352 days-old quail were allocated to four treatments with four replicates (22 birds each). Excreta were quantitatively collected during 18-21 days of age for measurement digestibility of nutrient. The dietary treatments were included control (0%) and the levels of four, eight and 12 percent OP. At 35 days old, from each replicate, two quails were randomly selected and slaughtered. The dietary treatments did not influence weight gain, feed intake, and FCR. The OP did not influence the relative weight of carcass, breast, thigh, heart, and spleen, but the highest relative weight of liver and gizzard were observed in 12 percent OP (p < 0.05). The ileum villus height was higher in birds fed OP as compared to control(p < 0.05). Crude protein and crude fat digestibility in chickens fed 12% OP and was increased compared to control (p < 0.05). Ash and phosphorous digestibility increased in chickens received 8% OP compare to control (p < 0.05). The olive pulp decreased the plasma MDA concentration as compared to control (p < 0.05), however, treatments had no significant effects on other blood indices. The lowest enzyme activity of AST was observed in the control and the highest enzyme activity of GPx and SOD were observed in 12% OP (p < 0.05). The results were indicated that the inclusion of olive pulp up to 12% had no detrimental effects on growth performance and blood lipid profile but significantly decreased plasma malondialdehyde (p < 0.05).
