Abstract

This research aims to evaluate the effects of inclusion levels of alcoholic extract of Baccharis dracunculifolia in broiler diets on performance and health of the birds. Will be used 936 broiler chicks, male, Cobb breed, distributed in a completely randomized design with six treatments and six replicates of 26 birds per experimental plot. The treatments will be employed: control diet (CD) without inclusion of performance enhancer antibiotic (PEA) and B. dracunculifolia, CD + 0.10% extract of B. dracunculifolia, CD + 0.20% extract of B. dracunculifolia, CD + 0.30% extract of B. dracunculifolia, CD + 0.40% extract of B. dracunculifolia, CD + PEA. Diets will be formulated based on corn and soybean meal, according to the recommendations of Rostagno et al. (2011) in four phases: pre-starter, starter, grower and finisher. The performance variables analyzed will be weight gain, feed intake, feed efficiency, viability and productive efficiency index; as health parameter for the broilers will be analyzed the antibody titer against Newcastle disease; as morphometric or histomorphometric parameters will be analyzed the relative weight of organs, intestinal histomorphometry and histomorphometry of cloacal bursa; moreover, will be evaluated the turnover rate of carbon in the intestinal mucosa and blood as an indication of development and tissue renewal.
