Allzyme SSF supplementation improves the utilization of sweet potato (ipomoea batatas) vine meal by growing pigs

Abstract

The effects of Allzyme SSF supplementation of sweet potato vine meal (SPVM) on the performance of growing pigs were investigated. A control diet based on fish meal and full-fat soybean as protein sources and diets containing 150 and 300 g/kg of SPVM with and without SSF were fed each to pigs in five replicates pens in a completely randomized design for a period of 84 days. There was no treatment effect (P >.05) on dry matter intake. The highest body weight gain was recorded on the SSF- supplemented SPVM groups (P .05), but per cent ham was markedly reduced on the control compared with the enzymesupplemented SPVM diets (P.05). Allzyme supplementation significantly reduced digesta weight in the large intestine (P
