Abstract

The European Union has prohibited the use of antibiotics in diets for broiler and, to suit the demands of this market without affecting the production, should seek for new alternatives. Thus, the use of mushrooms that may be similar to antibiotic action becomes an alternative. There are few works that aim to study the effects of mushroom of the species Pleurotus ostreatus and Agaricus blazei as growth promoters additives for broilers. Therefore, will be conducted an experiment in which will be used 900 male broiler chicks of line Cobb, distributed in a completely randomized design with six treatments and five replications. The treatments will consist of: T1 - negative control - basal diet (RB) without anticoccidial and antibiotic (not challenged birds); T2 - negative control - RB without anticoccidial and antibiotic (challenged birds); T3 - Positive Control - RB with inclusion of anticoccidial and antibiotic (challenged birds); T4 - RB with inclusion of 0.2% of mushroom Agaricus blazei (challenged birds); T5 - RB with inclusion of 0.2% of mushroom Pleurotus ostreatus (challenged birds). It will be obtained data on growth performance and intestinal morphology of broilers. The statistical analysis of the data will be made by the method of analysis of variance (ANOVA), with the aid of the GLM procedure of the SAS program (2012). In order to check for significant differences between the averages of the treatments will be used the Tukey test at 5% probability level.
