EFFECT OF MULTI-ENZYME SUPPLEMENTATION ON ENERGY CONCENTRATION, NUTRIENT AND FIBER DIGESTIBILITIES AND GROWTH PERFORMANCE OF NURSERY PIGS FED DIETS WITH CASSAVA MEAL

Abstract

Two experiments were conducted to determine the effect of multi-enzyme supplementation on energy concentration, nutrient and fiber digestibilities and growth performance of nursery pigs fed diets with cassava meal (CM). In Exp. 1, 20 barrows (initial BW=8.23 ± 0.70 kg, PIC L337×C24) were randomly allotted to 1 of 4 dietary treatments with 5 replicates per treatment. Dietary treatments were a basal diet, 60% basal diet + 40% CM with no enzyme or supplemented with either 60 mg/kg of a multi-enzyme containing endo-1,4-ß-xylanase and endo-1,3(4)-ß-glucanase or 110 mg/kg of a multi-enzyme containing endo-1,4-ß-xylanase, endo-1,3(4)-ß-glucanase, and a 6-phytase. In Exp. 2, 378 pigs (initially weighing 6.6 ± 1.7 kg; PIC L337×C24) were randomly allotted to 1 of 3 dietary treatments using a randomized complete block design. Dietary treatments were a control diet and a corn-soy diet with 20% CM with and without 200 mg/kg of a multi-enzyme containing endo-1,4-ß-xylanase and endo-1,3(4)-ß-glucanase. Each treatment had 6 replications with 21 pigs per replicate. Results of the two experiments showed that multi-enzyme supplementation did not improve the ME of CM, digestibility of nutrients and dietary fiber and growth performance of nursery pigs. Therefore, the multi-enzymes used in this study do not affect the feeding value of diets containing CM.
