This research was carried out to evaluate the effect of sunflower seed meal fermented with Aspergillus niger and Saccharomyces cerevisiae on performance, nutrient digestibility, immune response, some blood parameters in 200 male Ross 308 broiler chicks in a completely randomized design. with five treatments. Experimental treatments were: 1- Diet containing sunflower seed meal fermented by Aspergillus niger 2- Diet containing sunflower seed meal fermented by Saccharomyces cerevisiae 3- Diet containing sunflower seed meal fermented by both Aspergillus niger and Aspergillus niger 4- Diet containing sunflower seed meal without processing 5-Control diet based on corn and soybean meal. Feed intake in control and treatment 1 were higher than the other treatments in starter and finisher periods of the experiment (P<0.05). Daily Feed intake in control group was higher than the other treatments in whole period of the experiment (P<0.05). Daily weight gain in control and treatment 1 were higher than the other group in starter and grower periods of the experiment (P<0.05). Feed conversion ratio in treatment 1 was better in finisher phase. In whole period of the experiment, feed conversion ratio in control and treatment 1 was better than the other treatments (P<0.05). Dry matter, crude protein, crude fat digestibility in the control group was higher than the other treatments (P<0.05). In conclusion, inclusion of sunflower seed meal fermented with Aspergillus niger, in broiler diet showed similar feed conversion ratio in compared to control group in whole period of the experiment and also lowered abdominal fat percentage.

This study was conducted to determine the effects of Propolis on growth performance, carcass characteristics and some blood parameters in broiler chickens in response to heat stress condition. A total of 160 one day-old male broiler chicks (Ross 308) were randomly divided into four treatment groups in a completely randomized design with four replicates of 10 birds each. The experimental treatments including: 1) control (basal diet), 2) the basal diet with Neomycin (200 g/ton), 3) 150 mg/kg Propolis, 4) 200 mg/kg Propolis in diet. Birds submitted to heat stress (32±2ºC from 10.00 AM to 6.00 PM) from 15 to 42 d of age. The results showed that, average mortality was lower in Propolis groups than in the control group (p < 0.05). None of the feed intake data was influenced by treatments during different periods. Birds receiving diet supplemented with 200 mg/kg Propolis had a significantly (p < 0.05) higher body weight compared to the control group at the finisher feeding phase and whole period. In the finisher phase and whole period, the lowest (p < 0.05) fed conversion ratio (FCR) was observed in chickens fed 200 mg/kg Propolis. Cholesterol and LDL level were lower in chickens fed diet with Propolis compared to control (p < 0.05). In conclusion, the addition of Propolis at a rate of 200 mg/kg to the diet could reduce the negative effects of heat stress in broiler chickens.

The purpose of this study was to evaluate the effect of Zilpaterol hydrochloride on the growth performance, carcass quality and blood parameters with128 male quails at 26 days of age were divided into four treatments which each treatment consists of four replicates of 8 birds. The birds received daily 0, 0.2, 0.225, or 0.25 mg/kg of live weight d−1zilpaterol. After three days of withdrawing zilpaterol, two birds were slaughtered for carcass evaluation. Results showed that zilpaterol hydrochloride supplementation improved feed conversion ratio (FCR) (P<0.5), but no effect on feed intake and weight gain. Also, zilpaterol hydrochloride increased the glucose and triglyceride concentration of plasma in comparison to treatment control (P<0.5). However, zilpaterol had no effect on carcass chemical composition (crude protein, fat, cholesterol). Furthermore, carcass weight and percentage of leg, breast, liver and abdominal fat was not affected in the treatment which were feeding zilpaterolhydrochloride. It can be concluded that Zilpaterol hydrochloride improved the FCR in Japanese Quails
