Efficacy of Wheat Based vs. Corn Based Diet Formulated Based on Digestible Amino Acid Method on Performances, Carcass Traits, Blood Parameters, Immunity Response, Jejunum Histomorphology, Cecal Microflora and Excreta Moisture in Broiler Chickens

A study was conducted to evaluate efficacy of wheat based vs. corn based diets on growth performance, carcass traits, blood parameters, jejunum morphological development, immunity, cecal microflora and excreta moisture in broiler chicks fed according to digestible essential amino acid profile. One hundred forty day old Ross 308 male broiler chicks randomly distributed into ten separated floor pens based on a completely randomised design. Each treatment consisted of five replicates with fourteen birds each. Body weight ( BW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), immunity and excreta moisture were determined at different periods of ages. At the day 44, five birds of each group were sacrificed to evaluated carcass traits, jejunum histomorphology and cecal microflora. Blood parameters, mortality rate (MR) and European production efficiency factor (EPEF) were measured and determined at day 42 of age, respectively. The results of this study showed that BW, BWG, FI, FCR, MR and EPEF were not significantly different between two groups on the day 42 of age, but BW, BWG and FI were significantly higher (P 0.05) between two groups except for abdominal fat (AF) percentage which was significantly higher (P 0.05). Humeral immunity response, Newcastle titer, jejunum histo morphology, cecal microflora and excreta moisture were not significantly different (P>0.05) between two groups. In conclusion, wheat based diet is as efficient as corn based diet when diets are formulated based on digestible amino acids method.
