EFFECTS OF FEEDING GRADED LEVELS OF PALM KERNEL MEAL (PKM) IN BROILER CHICKEN DIETS SUPPLEMENTED WITH MAXIGRAIN® ENZYME.

Abstract:

A study was conducted to evaluate the effects of feeding graded levels of PKM in broiler chicken diets supplemented with or without Maxigrain® enzyme on the performance of broiler chickens. The first study is on nutrient retention, where eighty one (81) day old chicks of the Arbor Acres strain were randomly allotted to nine (9) isonitrogeneous dietary treatments with three replicates and three birds each in metallic cages. The PKM was included at 0, 10, 20, 30, and 40% levels while PKM treated with Maxigrain® was included at 10, 20, 30, and 40% levels. Results show that there was significant (P<0.001) differences in protein, fat, NFE and metabolizable energy retention in birds fed the control and Maxigrain® treated diets than those on diets without Maxigrain®. The second study was conducted to evaluate the effects of PKM in broiler diets treated with or without Maxigrain®. Four hundred and five (405) day old chicks of the Arbor Acres strain were randomly allotted to nine (9) isonitrogeneous dietary treatments where PKM was treated with Maxigrain® prior to its inclusion in the diets. The PKM was included in the diets as in the first study on nutrient retention. The results indicated that Maxigrain® treatment of PKM improved the utilization of PKM, improved feed: gain ratio and reduced the cost of production. The effects of PKM treated with or without Maxigrain® on broiler performance did not show any superiority over the control diet. The inclusion of PKM even at 40% with or without Maxigrain® attained a final weight above 1.5kg at 8 weeks. Therefore, PKM inclusion at 10, 20, 30, and 40% levels did not have any deleterious effect on broiler performance and health. The dressed weight (g), abdominal fat, pancreas and spleen were significantly (P<0.001) different across the dietary treatments. The percentage neck, breast and the intestines were also significantly (P<0.05) different across diets but no clear trends were established. The third study was conducted to evaluate the effects of PKM in broiler diets supplemented with or without Maxigrain®. Four hundred and five (405) day old chicks of the Arbor Acres broiler strain were randomly allotted to nine isonitrogeneous diets. The Maxigrain® was added to the already formulated diets at 0.01% to four of the nine diets. The PKM was included in the diets at the same levels as in the first study on nutrient retention. The results indicate that supplementation of PKM with or without Maxigrain® on broiler performance shows that the inclusion of PKM up to 20% with Maxigrain® was superior to the control diet and it is therefore recommended for optimum performance of broiler chickens.
