Effect of emulsifier supplementation on broiler chickens performance / Efeito da suplementação do emulsificante sobre o desempenho de frangos de corte

ABSTRACT

Strategies such as supplementation ingredients that maximize the feed digestion and absorption are indicated for improving broilers performance. The aim of this study was to determine birds performance fed with supplemented diets containing commercial emulsifier-based glycerol monostearate. Three hundred eighty four male broiler chicks (Cobb 500) with a day-old were distributed in a completely randomized design with 6 treatments and 8 replicates with 8 birds each. The treatments were CP positive control without energy reduction; CPE positive control without energy reduction + 120 g MT Emulsifier; CN100 CP with dietary reduction of 100 kcal kg ME; CN50 CP with dietary reduction of 50 kcal kg ME; CNE100 CN100 + 120 g MT of Emulsifier; and CNE50 CN50 + 120 g MT of Emulsifier. The birds were housed in cage for 21 days with water and food ad libitum. Performance parameters (feed intake, body weight gain and feed conversion) were measured. Data were analyzed using the Tukey test at 5% significance. When reduced 100 kcal kg ME in the diet without emulsifier there was a worsening of performance, however, with the use of emulsifier, broilers performance remained similar to the positive control diet. A reduction of 50 kcal kg of ME did not affect the measured parameters (Table 1).
