Effect of different oil sources on growth performance, carcass characteristics and blood metabolites of broilers was studied using 160 male Ross broiler chickens in a completely randomized design with 4 treatments, 4 replicates and 10 birds each. Treatments included: 1) basal diet plus soybean oil, 2) basal diet plus sunflower oil, 3) basal diet plus canola oil and 4) basal diet plus sesame oil. Effect of different oil sources on feed intake was not significant in different periods. In grower, finisher and whole periods, sesame and canola oil fed birds showed better weight gain and feed conversion ratio compared to other oil sources. The food cost was significantly higher for diets including sesame oil compared to others and birds fed sesame oil had lower profit than canola and soybean oil fed birds (P<0.05). The relative weight of carcass, breast and thigh was higher in broiler fed with sesame and canola oil (P<0.05). The blood cholesterol decreased significantly in sesame oil treatment (P<0.05). Considering the lower price and higher profit of canola oil containing diets compared to sesame oil and also better performance of birds fed sesame and canola oil, we would recommend using canola oil in broiler diets.

Abstract
This study was carried out to examine the effect of supplementation of canola and fish oils (5% fish oil, 3% fish oil + 2% canola oil, 2% fish oil + 3% canola oil and 5% canola oil) and Satureja khuzistanica essential oils (SkEO) (0 and 400 mg/kg), into a basal diet on productive performance, meat cholesterol, ...

This study was carried out to examine the effect of supplementation of canola and fish oils (5% fish oil, 3% fish oil + 2% canola oil, 2% fish oil + 3% canola oil and 5% canola oil) and Satureja khuzistanica essential oils (SkEO) (0 and 400 mg/kg), into a basal diet on productive performance, meat cholesterol, lipid stability and certain blood lipid components in broiler chickens raised under normal and heat stress conditions during day 22 to 42 of age. The experiment was conducted in a 4×2×2 factorial expriment using 640 one-day-old Ross 308 chicks in a completely randomised blocks design with 5 replicates of 8 birds in each replication. Oil source significantly decreased FCR, serum LDL and cholesterol content in thigh and breast muscles at day 42 of age. Inclusion of 400 mg/kg SkEO in diet significantly increased daily weight gain and decreased cholesterol content and TBARS concentration in thigh and breast muscles in heat stressed chicks. Heat stress condition significantly decreased FCR and increased TBARS as well as cholesterol content in breast muscle and serum cholesterol concentration during day 22 to 42 of age. It was concluded that supplementation of 400 mg/kg SkEO and canola oil into diet could have a positive effect on productive performance and reduce the meat and serum cholesterol concentration in broiler chicken.

An experiment was conducted to determine of the effects of vitamin E and C supplementation in diet based on different source of oils on performance and serum parameters of broilers. A total of 320 broiler chicks (Strain Ross 308) used in a 2×2×2 factorial arrangement in the form of completely randomized design with eight treatments, four replicates and 10 chicks in each replicate. Experimental factors included: two different oil sources (soybean and canola), two levels of vitamin E (zero and 200 mg/kg), and two levels of vitamin C (0 and 1000 mg/kg). Oil sources and vitamin E and C had no effect on performance of broilers. Supplementation of vitamin E or C increased serum total cholesterol and HDL (P<0.05). Source of oil had no significant effect on glucose and total serum cholesterol. Broilers fed diet containing canola oil had higher HDL and lower serum malondialdehyde than those fed diets with soybean oil (P<0.01). Supplementation of vitamin C to the diets containing canola oil decreased serum triglyceride compared with diets include soybean oil and vitamin C (P<0.05). Supplementation of vitamin E decreased serum malondialdehyde and increased activity of glutathione peroxidase (P<0.05). Results of this study indicate that dietary supplementation of canola oil, vitamin C or E to broiler diet increased serum HDL and vitamin E decreased oxidation of serum lipids by improving antioxidant system.
