Uso de butirato de sódio protegido em rações de frangos de corte

Abstract

The experiment was done by Poultry Section of the Center of Agricultural Science, Biological and Environmental of Federal University in Bahia’s Reconcav, in the city Cruz das Almas, State of the Bahia, to study the use of sodium butyrate in dietary of male chick (COBB), by animal since parameters: weight gain, feed intake, feed: gain ratio and feasibility. Were utilized 1488 chicks, with 6 treatments the 8 repetitions and 31 chicks per experimental unit. The experimental delineation was completely by chance. The six tested treatments had been: a basal diet of maize and soy without additives - Negative Control (NC), basal diet with enramicina - Positive Control (PC), NC + sodium butyrate source A; NC + sodium butyrate source B; PC + sodium butyrate source B. There was no statistically significant difference for any of the parameters evaluated, regardless of the source of sodium butyrate, with or without antibiotic growth promoter, allowing to conclude that the use of this organic acid can replace antibiotic growth promoter under similar management, ambience and health challenge.
