ABSTRACT

An experiment was conducted to investigate the effect of the addition of an appetite stimulant based on thaumatin in sorghum + soybean and sorghum + soybean + canola meal diets on broiler chicken productive parameters over a 49-day period. A 2 × 2 × 2 factorial arrangement was established, one factor was season of the year (hot April-May and cold December-January), another factor was the diet (sorghum + soybean and sorghum + soybean + canola meal) and the last factor was the presence or absence of the appetite stimulant (500 g/ton). At 49 days the results showed that the addition of the appetite stimulant increased weight gain (P ‹ 0.002) and feed consumption (P ‹ 0.000). An effect of the factor season of the year was observed on feed conversion (P ‹ 0.001). The data obtained showed that the addition of an appetite stimulant increased feed consumption (4.4%), which, in turn, contributed to an increase in weight gain (3.1%). This information demonstrates the potential of the appetite stimulant thaumatin to improve broiler chicken productivity.
