| ABSTRACT This study was conducted using Analytic Hierarchy Process (AHP) in order to rank broiler breeding farms in Zanjan province, Iran, regarding buildings, installations, and equipment to determine their effects on production factors. Data on 108 farms were collected using designed forms. This data was analyzed based on the effectiveness of each parameter in the production and management category according to experts’ opinion. The results indicated that ventilation systems (fans, inlets, and damper) as well as wall and roof insulation in poultry houses, constituted 66% of the technology coefficient. The stocking density increased through improvement of the mechanization coefficient. Most of these farms used longitudinal or tunnel ventilation and a... |

| ABSTRACT We hypothesized that the supplementation of vitamin C (Vit. C) and coenzyme Q10 (CoQ10) alone or in combination could reduce the negative effects of cold stress in broilers. Four hundred male chicks were exposed for 24 h to cold stress (15 ºC) starting from 15d of age, while a positive control group (PC, 100 birds) was kept under normal temperature condition. The experimental groups under cold stress (four treatments in 5 replicates of 20 birds) were: negative control (NC, basal diet), Vit. C (basal diet + 300 mg/kg Vit. C), CoQ10 (basal diet + 40 mg/kg CoQ10) and Vit. C plus CoQ10 (basal diet + Vit. C+ CoQ10at above mentioned doses). Vit. C or CoQ10 supplementation were restored (p<0.01) performance and lowered (p<0.01) ascites mortality.... |
