In this research, the effect of zinc and selenium synthesized from nano-mineralized probiotics was investigated on yield characteristics, egg quality characteristics, antioxidant status, and immune response of laying hens. A number of 576 high-line laying hens at the peak of production (from 25 to 37 weeks of age in three four-week periods) were used as a completely randomized design with a 3x3 factorial experiment with eight replications and eight birds per replication. Experimental treatments are 1. The control diet (without selenium and zinc), 2. Control diet + selenium chelate, 3. Control diet + zinc chelate, 4. Control diet + zinc synthesized from probiotics, 5. Control diet + selenium synthesized from probiotics, 6. Control diet + zinc chelate + selenium chelate, 7. Diet Control + zinc chelate + selenium synthesized from probiotic, 8. Control diet + zinc synthesized from probiotic + selenium chelate, 9. Control diet + zinc synthesized from probiotic + selenium synthesized from probiotic. The results showed that using zinc and selenium synthesized from probiotics increased production percentage, average egg weight, and improved feed conversion ratio (P<0.05). The serum concentration of cholesterol, triglyceride and malondialdehyde in chickens receiving probiotic zinc and selenium was the lowest. The serum HDL concentration and total antioxidant index were the highest compared to other treatments (P<0.05). In general conclusion, zinc and selenium synthesized from nano-mineralized probiotics have a better performance in laying hens.

In the present study, the effects of peppermint essential oil (PEO) and artifier in low energy diets on production index, feed cost, blood biochemical parameters and shelf life of meat of broiler chickens was investigated. A total of 240 male Ross broiler were used in a completely randomized design with 2×2 factorial method and compared with the control treatment (5 treatments) and 4 replications. Experimental treatments were include 1. control treatment and treatments containing low energy diets (150 kcal / kg less than the control diet) supplemented with 2. without additives 3. 150 ppm PEO 4. 300 ppm artifiers and 5. 150 ppm PEO + 300 ppm artifiers. The results showed that among broiler chickens fed low energy diets, the use of PEO + artifier in the diet increased body weight, production index (P=0.11) and decreased feed price (P<0.05) in the whole period. No difference was observed between birds fed control diet and birds fed low energy diet containing PEO + artifier in body weight, production index, survival percentage and feed price. Also, birds fed low energy diets containing PEO + artifier had lower serum cholesterol, low-density lipoproteins, triglyceride and meat malondialdehyde, and greater total antioxidant capacity, as compared to control diet. Finally, it can be concluded that the simultaneous use of 150 ppm PEO and 300 ppm artifier in low energy diets of broiler chickens compared to the control diet had the same performance and feed cost and improved blood biochemistry parameters and meat shelf life.

This study was done to investigate the effect of pomegranate peel extract on growth performance, blood biochemical indices, intestinal morphology and meat quality of broiler fed diet-contained soybean oil. 120 male broilers were used in the form of a completely randomized design with 3 treatments, 4 repetitions and 10 chicks. Experimental diets were three levels of zero, 300 and 600 mg/kg of pomegranate peel extract (PPE). Pomegranate peel extract had no effect on performance traits including feed intake, body weight and feed conversion ratio at starter and finisher phases, but in the grower period, the levels of 300 and 600 PPE reduced feed intake (from 928 to 777 g) and feed conversion ratio (from 1.77 to 1.31; P <0.05) compare to control. The breast percentage increased from 19.78 in control to 21.95 at the level of 600 PPE and the percentage of abdominal fat decreased from 1.93 in control to 1.27 at the level of 600 PPE (P <0.05). The PPE at levels of 600 reduced concentration of cholesterol (183.68 to 137.15 mg/dl) and LDL (95.63 to 32.93 mg/dl) and the enzyme activity of aspartate dehydrogenase (263.8 to 204.28) compare to control. The villus height (from 1026.88 to 1155.12) and the villus height to crypt depth ratio (5.04 to 5.6) were higher at the 600 PPE compared to the control. The concentration of Malondialdehyde in meat decreased at 15 and 30 days after slaughter with an increase in PPE compared to control.

To determine the effects of olive pulp(OP) on growth performance, nutrient digestibility, blood indices and intestinal morphology in Japanese quail, A total of 352 days-old quail were allocated to four treatments with four replicates (22 birds each). Excreta were quantitatively collected during 18-21 days of age for measurement digestibility of nutrient. The dietary treatments were included control (0%) and the levels of four, eight and 12 percent OP. At 35 days old, from each replicate, two quails were randomly selected and slaughtered. The dietary treatments did not influence weight gain, feed intake, and FCR. The OP did not influence the relative weight of carcass, breast, thigh, heart, and spleen, but the highest relative weight of liver and gizzard were observed in 12 percent OP (p < 0.05). The ileum villus height was higher in birds fed OP as compared to control(p < 0.05). Crude protein and crude fat digestibility in chickens fed 12% OP and was increased compared to control (p < 0.05). Ash and phosphorous digestibility increased in chickens received 8% OP compare to control (p < 0.05). The olive pulp decreased the plasma MDA concentration as compared to control (p < 0.05), however, treatments had no significant effects on other blood indices. The lowest enzyme activity of AST was observed in the control and the highest enzyme activity of GPx and SOD were observed in 12% OP (p < 0.05). The results were indicated that the inclusion of olive pulp up to 12% had no detrimental effects on growth performance and blood lipid profile but significantly decreased plasma malondialdehyde (p < 0.05).

In order to evaluate the effect of alkaline hydrolyzed feather meal on performance and lipid oxidation of meat and egg of laying quails, 64 adult quails at 40 day of age were used. Forty eight female and 16 male quails were randomly used in three to one proportion in separate cages in a completely randomized design with 4 treatments and 4 replicates of 4 birds in each. The experimental treatments consisted of control (containing soybean meal as major protein source), and treatments containing 3%, 6% and 9% alkaline hydrolyzed feather meal, respectively. During the experimental period, egg weight, feed conversion ratio, egg mass, feed intake and egg production percentage were measured. At the end of experimental period (82 days of age), two birds per cage were selected, slaughtered and the malondialdehyde content in fresh and stored meat and egg samples were determined. The results of this experiment showed that no significant difference was observed in feed conversion ratio, egg mass, feed intake and egg production percentage (P>0.05). The weight of egg in treatments containing 3 and 9 alkaline hydrolyzed feather meal was significantly (p < 0.05) decreased when compared with control and treatment containing 6% alkaline hydrolyzed feather meal in whole experimental period. The malondialdehyde content of meat and egg of laying quails was significantly (p < 0.05) decreased in groups fed alkaline hydrolyzed feather meal when compared to control treatment. The results of this study showed that the use of alkaline

In order to investigate the effects of different levels of iron nano-oxide(INO) on performance, egg quality parameters and the antioxidant status of laying hens, 96 Bovens layer hens at the production peak(28 weeks) were used. The experiment done for 8 weeks in a completely randomized design with 3 treatments, 4 replicates and 8 birds in each replicate. Hens were fed with experimental diets containing 0, 50 and 100 mg iron nanooxide/kg of diet. The performance indices included egg production, egg weight, egg mass, feed intake and feed conversion ratio were daily recorded. The qualitative parameters included yolk color index, egg shape, yolk height index, Haugh unit, Eggshell thickness, eggshell strength, Specific gravity and relative weight of albumen, yolk and eggshell were determined at the end of each period(28 days). At the end of experiment, two birds per replicate were bleed and the blood biochemical parameters were studied.The results were revealed that the iron nano-oxide had no effect on performance indices. Total protein and enzyme activity of alanine aminotransferase were not affected by dietary INO.Dietary supplementation of INO decreased the serum concentration of cholesterol, triglyceride, and LDL, and increased serum concentration of HDL, iron, zinc. The antibody titer against Newcastle disease were increased with increasing the levels of dietary INO. The yolk and serum concentration of MDA was increased by the addition of iron nanoparticles. Therefore, the addition of iron oxide supplementation can improve performance indices, some qualitative characteristics of egg and immune response and decrease serum lipid in laying hens.

This experiment was conducted to evaluate the effects of different levels of licorice essential oil on growth performance, meat quality and oxidative stability of meat by using 625 d-old Aryan broiler chicks in a completely randomized design with 5 treatments, 5 replicates and 25 birds per each. Dietary treatments included a control group which received no additive (basal diet) and two graded levels of licorice essential oil (100 and 200 mg/Kg) added to the control basal diet, and a basal diet including an antibiotic (Avilamycin, 150 mg/kg feed). Dietary treatments were iso-caloric and iso- nitrogenous. The results showed that the birds fed on diets containing 200 mg kg licorice essential oil had more daily gain, feed intake and feed conversion ratio compared to other treatments (P<0.05). The highest and lowest of concentration of malondialdehyde (MDA) after 150 min incubation for inducing oxidation, were belonged to the birds fed diets containing 400 mg/Kg licorice essential oil and control diet, respectively (P<0.05). Dietary treatment had no effects on water holding capacity (WHC) of thigh meat. In conclusion, dietary supplementation with 200 mg/Kg of licorice essential oil improves growth performance and increase oxidative stability of meat in broiler chicks.

This experiment was conducted to evaluate effect of hempseed on performance, immune response and plasma antioxidative activity and lipid profile in broiler chicks. A total of 250 one-day male broiler chicks (Ross 308 strain) were randomly divided into five treatments with five replicates (10 birds per cage). The treatments were: 1) Control diet (H0, no hempseed); 2) the diet contain 5% hempseed (H5); the diet contain 10% hempseed (H10); the diet contain 15% hempseed (H15) and the diet contain 20% hempseed (H20). Data were analyzed using of the PROC GLM of SAS 9.1 software and means were compared using of tukey test. The results of this study indicated that inclusion of hempseed up to 10% into diet significantly (P<0.05) decreased feed intake, body weight but had no significant effect on feed conversion ratio. Also, use of hempseed up to 5% into diet significantly (P<0.05) decreased plasma Malondialdehyde (MDA) content (P<0.05), but had no significant effect on humoral immune response. Plasma total cholesterol, triglyceride and HDL concentrations were not significantly altered. But plasma LDL concentration significantly (P<0.05) decreased in hempseed supplemented groups in compared with control group. In conclusion, although use of hempseed up to 5% into diet improved plasma antioxidative activity, but due to decrease performance, use of it up to 10% into diet was not recommended.
