PERFORMANCE OF BROILER CHICKS FED THE PALM KERNEL MEAL DIET SUPPLEMENTED WITH DIFFERENT ENZYME PRODUCTS

Abstract

An experiment using amino acid supplemented palm kernel meal (PKM) at a
level of 30 % with or without enzymes compared with an amino acid supplemented
corn-soy (CS) diet with or without enzymes was conducted to provide basic information about the effect of enzymes and high level inclusion of PKM on the perfonnance of broiler chickens. A total of 56-day-old chicks were used in a completely randomised factorial design experiment with two different diets (PKM and CS) and five enzyme treatments (nil, Gamanase, Hemicell mannanase, Allzyme SSF and combination of Allzyme SSF and Gamanase). The birds were fed ad libitum for three weeks. Water was available at all times. Analysis of variance indicated that there was no significant difference between amino acid supplemented 30% PKM with the enzyme combination and the amino acid supplemented corn-soy diets in body weight, feed intake or feed conversion ratio. Interactions between diet and enzymes were found in body weight and feed intake There was a greater body weight of birds fed the Gamanase supplemented PKM diet than of birds fed the combined enzyme supplemented com-soy diet. The feed intake of birds fed the Gamanase supplemented PKM diet was significantly higher than the feed intake of birds fed the Gamanase supplemented corn-soy diet.
