The experiment was designed as a 3 × 3 × 2 factorial arrangement of treatments, including (i) pomegranate peel (zero, 4%, and 8 percent), (ii) oxidized soybean oil (zero, 2%, and 4 percent), and (iii) alpha-tocopherol (zero and 200 mg/kg). Supplementation of 8% pomegranate peel in diets significantly decreased the growth performance of broiler chickens. The supplementation of 4% oxidized oil in diets significantly reduced body weight gain and Feed intake whole experimental period (p < 0.05). The results showed that supplementation of 4% pomegranate peel in the diet was associated with low aspartate transaminase (AST), alanine transaminase, and malondialdehyde (MDA). However, 4% pomegranate peel increased the total antioxidant capacity (TAC) and superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities. The supplemental 4% oxidized oil increased the serum AST, alanine aminotransferase (ALT), and MDA concentrations. TAC, SOD, and Catalase (CAT) activities were affected by 4% oxidized oil and alpha-tocopherol. The use of oxidized oil and vitamin E decreased MDA concentration. The serum glucose and globulin concentrations were significantly lower in the 8% pomegranate peel. The results showed that supplementation with 4% pomegranate peel in diets reduced serum low-density lipoprotein (LDL). The inclusion of 4% oxidized oil in diets reduced serum glucose and increased the blood lipid concentration such as triglyceride, cholesterol and LDL. Vitamin E supplementation reduced the serum cholesterol and LDL concentrations. The use of 8% pomegranate peel reduced red blood cell (RBC), hemoglobin, and packed cell value (PCV). The results indicated that supplementation with 8% pomegranate peel and 4% oxidized oil in diets decreased the immunoglobulin concentration in broilers. In addition, it was found that the inclusion of 4% pomegranate peel in diets resulted in higher IgG, IgM and total immunoglobulin. Pomegranate peel supplementation significantly decreased meat MDA concentration. Supplementation of 4% oxidized oil increased MDA of meat (p < 0.05). Vitamin E supplementation (200 mg/kg) significantly decreased MDA of meat (p < 0.05). Consequently, the results of this experiment showed that supplementation with 4% pomegranate peel had beneficial effects on broiler chickens. It was also found that feeding 2% oxidized oil in diets had no adverse effect on broilers.

C URRENT study was performed to investigate the effects of added different levels of common salt in the water on carcass characteristics and litter moisture of Japanese quail. Six hundred one-day old Japanese quail chicks(8.61±0.21 grams) divided to six treatments and five replicates of 20 birds per experimental units, based on completely randomized design for 42 days. All treatments fed the same diets and only the amount of sodium chloride in the water was different. Control treatment consumed conventional drinking water containing 233 ppm total dissolved solids (TDS) and other treatments consumed water supplemented with 1.32, 2.80, 3.80, 5.56 and 7.12 grams of NaCl per liter which were equal to 1233, 2233, 3233, 4233 and 5233 ppm for other experimental groups, respectively. At the end of experiment, four chicks from each replicate slaughtered and then carcass traits measured. The results showed that pre-slaughter weight, carcass and breast yield as well asdry matter content of thighs, breast, and ash content of breast,were significantly affected by water salinity. Higher amounts of TDS in drinking water often resulted in lower pre-slaughter weight and carcass and breast yield; but greater dry matter content of thighs and ash content of thighs and breast observed in tested Japanese quails. Litter moisture content also significantly increased by increasing TDS levels in drinking water. Inconclusion, in order to maintain carcass characteristics and litter qualityof quailsat the safe range, amount of TDS in drinking water should not be more than 2233 ppm.

Agricultural residues can be used as alternative feed sources in industrial chicken production. The impacts of different levels of pomegranate peel and waste cooking oil as an agricultural residue on broilers' nutrition were investigated. Results showed that the replacement of 8% pomegranate peel in diets decreased the growth performance of broilers. Supplementing 8% pomegranate peel in diets reduced apparent nutrient digestibility. The highest level of waste oil inclusion in broiler diets indicated negative impacts on apparent zmetabolizable energy and crude fat apparent nutrients digestibility. Broilers fed the diet containing 4% pomegranate peel had a higher Lactobacillus population. The results showed that the Lactobacillus population was lower in broilers fed 8% pomegranate peel powder and 4% waste oil in diets. The inclusion of 8% pomegranate peel powder in diets showed lower villus height and crypt depth in the duodenum, jejunum, and ileum. The inclusion of 4% pomegranate peel decreased the peroxide value (PV) of meat. Dietary inclusion of 4% waste oil raised the PV of meat. Alpha-tocopherol supplementation decreased the PV of meat. Finally, the results provide information that 4% of pomegranate peel and 4% waste oil could be used as an alternative feed ingredient in broiler diets without adverse effects.
