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.
