1 - Effect of different levels of selenium and vitamin E on blood biochemical parameters in the Japanese quail

Also, controversial reports exist for the effect of vitamin E and selenium on avian performance. This study was designed to investigate the effect of different levels of selenium (0, 0.2 and 0.4 mg/kg) and vitamin E (0, 150 and 300 mg/kg) in the diet of the Japanese quail. Birds received mesh diet from the start of the study, then selenium and vitamin E were added on day 17. At the end of the study, after food deprivation for 6 hours, Japanese quail (1 male and 1 female) were selected and blood samples collected for biochemical investigations and determination of glucose, albumin, total protein, cholesterol, triglyceride, HDL and LDL levels. There was significant decrease in cholesterol, glucose, and triglyceride levels and significant decrease in albumin and total protein levels on day 35 (p<0.05). Effect of vitamin E and selenium was not significant on serum LDL level but, administration of vitamin E significantly increased serum HDL levels (p<0.05). These results suggest that co-administration of selenium and vitamin E could have positive effects on blood biochemical parameters in the Japanese quail. Manuscript profile -

4 - The Effects of Replacement Vitamin E with Dietary Grape Pomace in Diets Containing Oil or Beef Tallow on Growth Performance, Blood Characteristics, Oxidative Status, and Gut Morphology of Broiler Chickens

Four MoreTo investigate the effects of replacement vitamin E with dietary grape pomace in the diets containing oil or beef tallow on growth performance, blood chara­cteristics, oxidative status, and gut morphology of broiler chickens, the present study was carried out. Four hundred and fifty-one-day-old broiler chickens were used in a completely randomized design with six treatments and five replicates. Experimental treatments were as follows; 1- control oil (CO, basal diet containing 3.5 percent soy oil) with 200 mg/kg vitamin E, 2-contraol tallow (CT, basal diet containing 3.5 percent tallow) with vitamin E, 3- CO with 9 percent grape pomace (GP), 4- CT with 9 % GP, 5- CO with 9 percent GP and vitamin E,6- CT with 9 % GP, and vitamin E. The results of this experiment showed that in the whole period, the birds fed diets containing soy oil, GP and vitamin E had the highest body weight gain and production index and the lowest feed conversion ratio compared to the others. The blood concentration of glucose, cholesterol, triglycerides, and high-density lipoproteins were reduced when GB was used in diets. Blood superoxide dismutase and glutathione peroxidase concentrations were increased, and malondialdehyde concentration was decreased when GP was used in broiler diets. In the duodenum part of the small intestine, villus height, crypt depth, villus height to crypt depth ratio, and muscularis thickness were increased when GP was used in broiler diets. To conclude, the result of this experiment suggests that although the GP has strong antioxidant properties, the simultaneous using vitamin E has a better effect on broiler growth performance.
