The aim of this study was to investigate the effect of emulsifier in diet with with energy reduction on performance, carcass characteristics and some of blood traits of broilers. A total of 540 one-day-old chicks of Ross 308 strain in a 3×3 factorial arrangement with three levels of emulsifier (0, 250 and 500 mg / kg) and three levels of dietary energy (requirement, and 45 and 90 kcal/Kg, 60 and 105 kcal/kg and 75 and 120 kcal/kg less than requirement for the starter, grower and finisher diets, respectively) in a completely randomized design with 9 treatments, 4 replications and 15 birds per replication were used. In total rearing period, feed intake increased by decreasing the dietary energy (P<0.05). Birds fed diets supplemented by emulsifier had higher weight gain and lower feed conversion ratio (P<0.05). The relative weights of the liver, ceca, and abdominal fat were not affected by different levels of dietary energy. The emulsifier × diet interaction had no significant effect on cholesterol, High-density lipoprotein (HDL), Low-density lipoprotein (LDL), cholesterol: HDL, Alanine aminotransferase (ALT) and alkaline Phosphatase. Adding emulsifier to normal diets or diets with more energy deficiency increased blood triglyceride concentration (P<0.05). Supplementing diets with mild energy deficiency by emulsifier increased serum Aspartate aminotransferase (AST) (P<0.05). According to the results, the use of 250 gr/t emulsifier in low energy diets improved the performance of broiler chickens.

The effects of feeding fermented cottonseed meal on performance, egg quality characteristics, gastrointestinal microbial population, and blood serum parameters were studied in a completely randomized design with nine treatments, six replicates, and 12 birds per replication using 648 Hy-Line W-36 laying hens. Raw cottonseed meal was fermented with a liquid mixed culture containing Lactobacillus plantarum, Bacillus subtilis, and Saccharomyces cerevisiae with a ratio of one to 1.2. The experimental treatments included replacing 7.5, 15, 22.5, and 30 percent of the raw or fermented cottonseed meal with soybean meal in the diet. After seven days of fermentation, free gossypol content of cottonseed meal was reduced from 985 to 107 mg/kg (P<0.05). The use of different levels of fermented cottonseed meal in the diet increased egg production percentage and egg mass and decreased feed conversion ratio compared to raw cottonseed meal (P <0.05). The eggshell strength in hens fed diets containing fermented cottonseed meal was higher than control birds and chickens receiving diets containing raw cottonseed (P <0.05). Feeding the diets containing different levels of fermented cottonseed meal significantly increased lactic acid bacteria population in crop and cecal of laying hens (P <0.05). Blood cholesterol concentration was lower in birds receiving diets containing fermented cottonseed meal than in other birds (P <0.05). The results of this research showed that replacing fermented cotton meal up to 30% with soybean meal in the diet of laying hens improves the parameters of eggshell quality, microbial flora in the gastrointestinal tract, and blood cholesterol of laying hens without negatively affecting performance.

This experiment was conducted to study the effect of different dietary n-6: n-3 fatty acid (FA) ratio on performance, egg quality, some blood and reproductive parameters of Japanese quails breeder. A total of 720 Japanese quails (Coturnix coturnix japonica) were used in a completely randomized design with five treatments, six replicates and 24 birds (16 females and eight males) in each replicate. Dietary treatments were control (n- 6: n-3 FA ratio were 13:1) and different n-6: n-3 FA ratios (1:1, 3:1, 6:1 and 9:1). The results showed that, quails fed diet with n-6: n-3 FA ratio of 1:1 had the highest feed intake in comparison with the others (P <0.05). Egg mass of quail was increased significantly when their diets containing n-6: n-3 FA ratio of 6:1, in comparison with 9:1 and control (P <0.05). The birds fed diets containing n-6: n-3 FA ratio of 1:1 and 6:1 had higher eggs Haugh unit rather than control (P <0.05). Feeding quails with diets containing n-6: n-3 FA ratio of 1:1 to 9:1 reduced serum triglyceride concentration compared to the control group. Blood cholesterol concentration of birds that fed diets containing n-6: n-3 FA ratio of 1:1 and 6:1 was lower than control and blood glucose was the highest in the birds that fed diets containing n-6: n-3 FA ratio of 1:1 (P <0.05). The results of this experiment showed that the use of dietary n-6: n-3 FA ratio of 6:1 in breeder quail diets can improves production performance.

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.

Present study was designed to investigate the effect of Artichoke (Cynara Scolymus) extract on performance and some blood and anti-oxidantparameters of Sanjabi lambs. Eighteen Sanjabi lambs were randomly allocated to three experimental treatments with six replicates in each individualcage for 75 days. The experimental treatments were: 1) control group including basal diet without Artichoke extract, 2) basal diet plus 5 ml ofartichoke extract, and 3) basal diet plus 10 ml of artichoke extract per kilogram dry matter. The blood samples were collected from jugular vein oflambs before feeding at morning monthly. The concentration of glucose, cholesterol, total protein, urea, albumin, and the activity of glutathioneperoxidase, superoxide dismutase, alkaline phosphatase, alanine aminotransferase enzymes and malondialdehyde were measured. The results of thisexperiment showed that artichoke extract had no significant effect on lambs' performance and growth parameters, but significantly decreased bloodconcentration of cholesterol, triglyceride and malondialdehyde index at the level of 10 ml extract per Kg/DM of diet. The urea and cholesterolconcentrations affected by time and at days 40 of experiment, the amount of this parameters was lower than other times. In general, it can beconcluded that artichoke extract at the level of 10 ml extract had no significant effect on average daily gain and growth performance of lambs butimproved some blood parameters.

This study was conducted to investigate the effect of different level of garlic powder on the performance, egg quality traits and blood parameters in commercial laying hens. A total of one hundred and twenty eight 58-wk-old Lohmann lite (LSL) hens were allotted into 4 dietary treatment groups replicated 4 times with 8 hens per replicate in a completely randomized design. Experimental diets included of control diet (no supplemented garlic powder) and 3 levels of garlic powder, (1, 2 and 3% of diet). Laying performance traits and egg quality parameters were recorded by replicate at 61 and 63 wk-old. Blood and egg yolk parameters were measured at the end of the trial. Results indicated that egg production percent, egg mass, feed intakeand feed conversion rate were not affected by experimental treatments. However, egg weight was increased by 3% garlic powder compared with the control diet (P<0.05). Haugh unit of eggs increased by 4.25 units, at 3% garlic powder over the control diet (P<0.05). Garlic powder supplementation of laying hen diets at 3% level lead to decreases in serum and egg yolk cholesterol (P<0.05). Blood parameters including high density lipoproteins, triglycerideand liver aspartate aminotransferase and alanine aminotransferase were not affected by treatments. In conclusion, dietary supplementation of garlic powder improved egg weight and albumen quality of eggs and has also lowering effect on cholesterol content of egg yolk.

In order to evaluation the effect of Nigella Sativa supplementation on performance, immune response and some of blood parameters, a total of 192 one day old Ross 308 broilers were used in a completely randomize design with four treatments, four replicates and 12 observations in each replicate. Treatments included the increasing levels of zero (control), 0.4, 0.8 and 1.2 percent Nigella sativa. In grower and whole period of experiment, the weight of birds received 0.4 and 0.8 percent of Nigella sativa was higher than control group birds (P<0.05). The supplementation of Nigella sativa in diet has not effect on feed intake and feed conversion ratio in starter, grower and total rearing periods. The weights of bursa and thymus in birds received 0.4 and 0.8 percent of Nigella sativa werehigher than control group birds (P<0.05). The weight of liver in birds belong to 0.4 percent of Nigella sativawas higher than control group (P<0.05). Addition of Nigella sativa in dietreduced the glucose, triglyceride, cholesterol, LDL and increased the HDL in blood serum. The use of Nigella sativa in dietary of birds caused the higher total white blood cells and lower heterophil: lymphocyte ratio. The birds which received 0.4 and 0.8 percent of Nigella sativa had the higher total antioxidant capacity than control group in blood plasma. In conclusion, the use of Nigella sativa up to 0.8 percent in diet, in addition to improvement the performance, increased the immune system activity and total antioxidant capacity in Ross 308 broiler chickens.

This study was conducted to investigate the effects of different levels of soybean lecithin on performance and blood lipids of broiler chicks. A total of 180 one day old Ross 308 broiler chicks were used in a completely randomized design with nine treatments (diets with 0, 0.2, 0.4, 0.6, 0.8, 1, 1.2, 1.4 and 1.6 percent of soybean lecithin) and four replicates for 47 days-rearing period. In order to evaluate the biochemical factors of blood including cholesterol, triglyceride, high density lipoprotein and low density lipoprotein, blood sampling from chickens were taken in day 41. The traits of weight gain, feed intake and feed conversion ratio were evaluated at the end of each period. The results showed that different levels of soybean lecithin had no significant effect on weight gain, feed intake and feed conversion ratio traits during each period. Increasing in the level of lecithin, decreased the concentration of cholesterol, triglyceride and low density lipoprotein and increased the high density lipoprotein concentration in blood plasma (P<0.05). In conclusion, dietary inclusion lecithin up to 1.6 percent, have no any effect on broiler performance, but could reduce cholesterol, triglyceride, and low density lipoprotein and increase high density lipoprotein in blood’s plasma.

This study was carried out to investigate the effect ofadministration of Satureja khuzistanica essential oil (SkEO) in drinking water on performance, lipid oxidation, activity of antioxidative enzymes and cholesterol content of thigh meat using 720 one-day-old Ross 308 broiler chicks. The SkEO was added into drinking water at zero (control-), 200, 300, 400 and 500 mg/L along with a treatment consisting polysorbate-80 (control+) at 500 mg/L. Inclusion of SkEO in drinking water significantly decreased water intake and improved production efficiency index of the birds during days one to 42 of age (P<0.05). The concentration of thiobarbitoric acid reactive substances in thigh meat was significantly decreased by SkEO-treated water (P<0.05). Addition of SkEO into drinking water significantly decreased superoxide dismutase as well as glutathione peroxidase activity in raw thigh meat of the birds (P<0.05). Catalase activity was not influenced by SkEO-added water (P>0.05). Lipid content and cholesterol level in thigh meat was significantly decreased in the birds received 500 and 200 to 400 mg/L SkEO through drinking, respectively (P<0.05). It could be concluded that administration of Satureja khuzistanica essential oils into drinking water at minimum 200 mg/L promoted meat lipid stability. Cholesterol levels of thigh meat decreased by SkEO at 200 to 500 mg/L.
