In order to evaluate the effect of different levels of corn gluten feed on performance, immune responses, intestinal morphology and some blood serum biochemical parameters of broiler chickens, an experiment was conducted using 500 male Ross 308 broiler chickens in a completely randomized design with four treatments, five replicates and 25 birds per replication. The experimental treatments included levels of zero (control), 2.5, 5 and 7.5 percent corn gluten feed in the diet which fed to broilers from 15 to 42 days of age. The results showed that dietary inclusion of corn gluten feed up to 7.5 percent had no significant effect on average weight gain, feed intake and feed conversion ratiocompared to control treatment. Also, jejunal morphological indices and blood biochemical parameters including triglyceride, cholesterol, albumin, phosphorus and alkaline phosphatase concentrations, livability, European broiler index and feed cost per kg of weight gain were not affected by dietary treatments. Antibody titer in response to sheep red blood cell (SRBC) injection was higher in treatment containing 2.5 percent corn gluten feed comparing to other treatments (P<0.05). Based on the obtained results, corn gluten feed can be included in grower and finisher diets of broilers (15 to 42 days of age) up to level of 7.5 percent without any adverse effect on performance.

Two experiments were conducted to determine the AME content of garlic powder and to investigate its effect as well as vitamin E and Loxidan (as a commercial antioxidant) supplemented in the diet, on growth performance, carcass analysis and meat oxidative stability. In the first experiment, the AME was determined in Leghorn roosters fed diets containing 5, 10, 15 and 20% of garlic powder, whose value appeared to be 2370, 2300, 2090 and 2065 kcal/kg, respectively. In the second experiment, a 2×2×2 factorial arrangement including two levels of garlic powder (0 and 2 percent), two levels of vitamin E (0 and 200 mg/kg), and two levels of Loxidan (0 and 200 mg/kg) were employed in four replicates and twelve broiler chicks in each. According to results, growth performance, the ratio of eviscerated carcass, breast, thigh and abdominal fat to live weight were not affected by garlic powder, vitamin E and antioxidant as they were applied individually. However, applying garlic powder along with Loxidan resulted in better daily weight gain (P<0.05). Moreover, using vitamin E along with Loxidan in diets led to meat oxidative stability (P<0.05). The findings of this study indicate that dietary individual supplementation of garlic powder in diet has no effect on growth performance, while using vitamin E and Loxidan may improve some characteristics such as meat oxidative stability.

The present study was carried out to evaluate the effects of vegetable fat sources and additives on performance and morphological parameters of the small intestine of Arain broiler chickens. Birds were randomly used in a 2×3 factorial arrangement of dietary treatments included two fat sources (canola or pumpkin seed) and three additives (without additive, 0.1 g/kg probiotic and 0.15 g/kg virginamycin) with four pen replicates and 20 birds per each. The growth performance and productive traits, with using of neither additives nor fat sources or fat sources × additives were unaffected. However, probiotic was significantly decreased crypt depth and increased villi height to crypt depth ratio in jejunum and ileum (P<0.01). Likewise, the highest of villi height and villi height to crypt depth ratio in jejunum and ileum especially was obtained with combination of pumpkin seed oil and probiotic (P<0.05). Crypt depth, villi thickness and surface area was higher in duodenum of broilers were fed with pumpkin seed oil (P<0.05).Thus, probiotic bactocell can be used in diets contain linoleic-oleic (pumpkin seed oil) and linolenic (canola oil) fat groups without negative effect on performance and productive traits.

This experiment was conducted to determine the effect of vitamin C (VC) and coenzyme Q10 (CoQ10) onimmunity response of broilers in cold stress condition using 500 male chicks in a completely randomizeddesign with 5 treatments and five replicates. Treatments were: positive control (PC, normal conditionsgrowth without antioxidants), negative control (NC, cold stress without antioxidants), cold stress + VC(300 mg/kg diet), cold stress + CoQ10 (40 mg/kg diet) and cold stress + VC + CoQ10 at above mentioneddoses. To induce cold stress, from day 15 until end, temperature fixed at 15oC. Vaccine titers, humeraland cellular immune response and relative immune organs weight were studied. Results showed that coldstress decreased relative spleen weight but there was no significant difference between treatments.Relative weight of bursa was increased in cold stress condition (P<0.01) and using antioxidant especiallyCoQ10 decreased it (P<0.05). Lymphocyte percent decreased in cold stress (P<0.05). Improved cellmediatedimmune response to subcutaneous injection of phytohemagglutinin and proliferation of Tlymphocyte in vitro were observed (P<0.05). In conclusion, use of antioxidants VC and CoQ10 in the coldstress condition improved immune system activity and decreased mortality
