Abstract:

The aim of this study was toinvestigate the effect of pomegranate peel extract (PPE) on the growthperformance, carcass characteristics, blood indices, intestinal morphology andmeat stability of broiler chickens. A total of 120 one-day-old Ross 308chicks were used in this study in a completely randomized design with threetreatments each replicated four times. The experimental treatments included were:0, 300 and 600 mg PPE/kg. Allstarter rations had four percentages of canola oil and grower and finisherdiets had six percentages of canola oil. The results showed that the PPE had nosignificant effect on performance of broiler chicks, including feed intake,body weight and feed conversion ratio. Pomegranate peel extracts (600 mgPPE/kg) increased the relative weight of bursa of fabricus (0.22 vs.0.11%) and decreased abdominal fat (0.92 vs. 1.93%) as compared tocontrol. The 600 PPE diet had lower concentration of serum cholesterol (147.95 vs.155.78 mg/dL), and LDL (44.45 vs. 53.36 mg/dL) than control diet (P<0.05). Compared to control group, thelevel of 600 PPE reduced the activity of lactatedehydrogenase (1111 vs. 2182 μL) and aspartate aminotransferase (210 vs.239 u/L). The stability of the meat during storage (0.85 vs. 0.99 ng/g) increasedin birds fed diets contained PPE as compared with control group. The birdsreceived PPE had higher jejunal villus height (1245 vs. 1027 μm) and thecrypt depth to the villus height (6.74 vs. 5.05) compared to the control.It is concluded that PPE supplementation at the level of 600 mg/kg of diet improvedmeat stability and morphology of jejunum and reduced the blood cholesterol ofbroiler chickens.
