The effects of different sources of copper supplementation on growth performance, some blood biochemical and immune parameters, microbial population of small intestine and meat quality were investigated with using of 240 male broiler chicks in a completely randomized design with 5 treatments and 4 replicates from 1 to 42 days. Treatments consisted of control treatment (basal diet without copper supplement) and four diets containing 16 mg/kg of copper-glycine, copper-sulfate, copper-nanochelate and copper nano-glycinec. The results showed that the use of different sources of copper had no effect on growth performance, some blood biochemical parameters and percentage of heterophil, lymphocyte, white blood cell, antibody titer against Newcastle disease, cholesterol, triglycerides and water holding capacity and pH of meat of broilers. Gastrointestinal relative weight in birds fed with diet containing copper-glycine was lower than the birds receiving copper-nanochelate (P<0.05). The total microbial population of ileum in birds fed diets without copper and copper-sulfate was higher than birds receiving diet containing copper-glycine (P<0.01). Meat malondialdehyde concentration of birds fed with diets containing copper-glycine and copper nano-glycine after 6 day of storage at refrigerator was lower than other birds (P<0.01). According to the results, the use of 16 mg/kg of copper from organic, mineral and nano sources in the diet has no effect on growth performance, immune system and ileal microbiota in broilers, but the use of copper-glycine and copper nano-glycine supplements in the diet reduces the oxidation of meat.

The effect of garden thyme essential oil (TEO) and rapeseed oil (RO) on performance, immune traits and intestinal morphology using 432 one-day-old Ross 308 male broiler as a (3x3) factorial experiment in a completely randomized design including different levels of TEO (0, 300 and 500 ppm) and RO (1, 3 and 5 percentage) were evaluated with 9 treatments and 4 replicates. Throughout the rearing period, broiler chickens receiving 3% gained more weight than 1% of RO and chickens receiving 300 ppm gained more weight than those without TEO (P˂0.05). The use of 3% RO + 300 ppm TEO increased the thigh percentage compared to 1% RO. At 1 and 5 percentage levels of RO, with increasing levels of TEO in the diet, blood cholesterol and LDL concentrations decreased and blood HDL increased (P<0.01). Levels of 3% and 5% of RO + 300 and 500 ppm of TEO in broiler chicken diets increased lymphocyte percentage and antibody titer against Newcastle disease and decreased heterophil percentage and heterophil to lymphocyte ratio of blood (P<0.05). Broiler chickens receiving diet containing TEO had the highest ratio of villi height to crypt depth (P<0.01). Based on the results, the level of 3% rapeseed oil + 300 ppm thyme essential oil in the diet of broiler chickens can be used to improve performance, immunity and biochemical traits of blood.

The effects of different sources of selenium supplementation and rosemary essential oil on growth performance, microflora population and intestinal morphology in broiler chicken with using of 480 male broiler chicks in a factorial arrangement (2x5) with 10 treatments and 4 replicates were investigated. Two experimental factors consisted of different sources of selenium (level of 0.3 mg/kg of diet from selenomethionine, nanoselenomethionine, selenitsodium, nano selenium bonza and without selenium) and rosemary essential oil (0 and 300 mg/kg of diet). Results showed that broilers received diet of without Se and rosemary essential oil had lower weight gain and feed intake.Broilers received diet of nano selenium bonza with rosemary essential oil had lower feed conversion ratio as compared to the other broilers (P<0.05). Broilers fed on diets of nanoselenomethionine with rosemary essential oil and nano selenium bonza with rosemary essential oil were increased villus height in jejunum (P<0.05). The crypt depth of intestinal in birds which received nanoselenium was more than the birds that consumed other sources of selenium in the diet (P<0.05). Crypt diameter nano selenium bonza with rosemary essential oil treatment was higher as compared to other treatments (P<0.01). Selenomethionine and nanoselenomethionine alone and in combination with rosemary essential oil treatments had high lactobacillus population and lactobacillus population to total microbial population ratio of ileum as compared to without Se and rosemary essential oil treatment (P<0.05). Based on the results, inclusion nanoselenium (0.3 mg/kg) supplement with rosemary essential oil (300 mg/kg) into the diet of broiler chicken can improve performance, gut morphology and microflora.

This study aimed to evaluate the effect of L-arginine on qualitative characteristics and fatty acid profile of Ross 308 aged broiler breeder roosters’ sperm. Twelve breeder roosters at age of 52 week were used in a completely randomized design with three treatments and four replicates in each treatment for eight consecutive weeks. Experimental groups were consisting diets with levels of 0.52 (Ross recommendation 308), 0.68 and 0.83 present of arginine amino acids. Semen collection was performed every 14 days and in weeks 54, 56, 58 and 60 were tested. At the end of the trial, fatty acid profile of sperm was also evaluated. On week 56, semen volume in roosters with 0.68 present arginine was higher than other treatments (P<0.05). On week 60, levels of 0.52 and 0.68 percent arginine in semen volume, percentage of total and progressive motility were higher than the level of 0.83 percent of arginine (P<0.05). On week 58, the percentage of abnormal sperm were lower in 0.68 and 0.83 percent arginine treatment compared to 0.52 percent arginine (P<0.05). Semen concentration, sperm plasma membrane functionality and sperm fatty acid profile were not affected by treatments used in this study. It can be concluded that 0.68 percent of arginine (30% higher than recommendation) of diet improve some qualitative sperm parameters in aged broiler breeder roosters.

This study was carried out toinvestigate the effect ofmannan-oligosaccharide prebioticonperformance,egg quality, immune response, intestine ileum microflora and nutrient digestibility in laying hens fed various levels of crude protein. A total of 150 Hy-Line W-36 layinghens were assigned to a 2×3 factorial arrangement of treatments. Experimental diets consisted of 3 levels of crude protein (recommended level for strain, 90 and 95% of recommended level) and 2 levels of mannan-oligosaccharides (0 and 0.1% of diet). Reduction of crude protein to 10% of basal diet resulted in decrease of egg weight, egg production, egg mass and feed conversion ratio (P<0.01). Supplementation of mannan-oligosaccharide into the diet improved egg production and egg mass (P<0.05). Newcastle antibody titer, primary and second antibody response against sheep red blood cell increased by supplementation of mannan-oligosaccharides (P<0.05). Reduction of crude protein to 5% reduced blood serum triglycerides concentration (P<0.05). Reduction of crude protein to 5 and 10 % of diet caused increases in digestibility coefficients of organic matter and Reduction of crude protein to 10 % caused decline of crude fat digestibility (P<0.05). Dietary supplementation mannan-oligosaccharides increased crude fat digestibility and decreased ileal E. coli count (P<0.05). So, supplementation of mannan-oligosaccharide at levels of 0.1% of diet improved immune parameters and intestinal ileum microflora. Similarly, crude protein at levels of 15.68% of diet did not reduced performance parameters of layinghens from age 47 to 57 weeks.

This study was carried out to investigate the effects of Humulus lupulus essential oils as an alternative to antibiotic and antioxidant on productive performance, lipids stability of meat and ileum microbial population in broiler chickens during days 1 to 42 of age. A total of 625 day-old Arian broiler chicks were used in a completely randomized design with five treatments (200 and 400 mg/kg Humulus lupulusessential oils, 100 mg/kg antibiotic avilamycin, 150 mg/kg protexin probiotic and control) and five replicates of 25 birds each. Broilers that were fed dietary Humulus lupulus oil at level of 400 mg/kg and antibiotic revealed higher feed intake than broilers fed dietary Humulus lupulusoil at level of 200 mg/kg (P<0.05). Dietary Humulus lupulus oil at level of 200 mg/kg and probiotic had best production index compared with Humulus lupulus oil at level of 400 mg/kg treatment (P<0.05). The Humulus lupulus oils (200 and 400 mg/kg) treatments showed lower thigh muscles malondialdehyde concentration compared with antibiotic and probiotic treatments as well as control group (P<0.01). Broilers were fed dietary 400 mg/kg Humulus lupulus oil had highest lactobacillus count of the ileum compared with other treatments (P<0.05). Dietary Humulus lupulus oil at level of 200 mg/kg improved broiler productive performance, however improvement of ileum microbial population and meat quality were observed when 400 mg/kg dietary Humulus lupulus oil was applied.

Effects of chromium nano particles (NanoCr) on performance and meat quality of Japanese quail under physiological stress was determined by using 360 birds in a completely randomized design with six treatments, four replicates and 15 birds per each, during 17- 35 d of age. The tratments were negative control (non-stressed), and five groups under physiological stress which fed on diets supplemented with different levels of NanoCr (0, 200, 400, 800 and 1200 µgkg-1). Dexamethasone (0.6 mgkg-1 BW) was added to diet for induction of physiological stress. Physiological stress reduced feed intake and growth, whereas increased feed conversion ratio (FCR) and thigh and breast muscles malondialdehyde (MDA) concentration (P<0.05). Stressed birds were fed on diets containing increased levels of NanoCr linearly improved weight gain (P< 0.02), and decreaced FCR (P< 0.05), MDA levels in breast (P< 0.04), and thigh muscles (P< 0.006). The results showed that supplementation of diet with NanoCr can alleviate the negative effects of physiological stress on performance and meat quality of quails.

This experiment was conducted to evaluate the effects of different levels of Artemisia Sieberi oil (zero, 100, 200 and 300 mg/kg) and antibiotic on performance and blood parameters in broiler chicken. 200 day-old broiler chickens (Ross 308) were allocated to five treatments, four replications with a completely randomized design. In total period, broilers were fed dietary Artemisia Sieberi oil at level of 300 mg/kg had higher weight gain than other experimental treatments (P<0.05). Control treatment had worse feed conversion ratio compared with broilers were fed dietary Artemisia Sieberi oil at levels of 100 and 300 mg/kg (P<0.05). The level of 100 mg/kg of dietary Artemisia Sieberi oil significantly increased the white blood cell value compared with other treatments (P<0.05). Red blood cell value significantly increased at levels of 100 and 300 mg/kg of dietary Artemisia Sieberi oils compared with other treatments (P<0.05). In this study, dietary Artemisia Sieberi oil at levels of 300 mg/kg improve broiler performance and can be considered as an alternative to antibiotic growth promoter.
