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.
