Abstract: Sixty growing pigs (Landrace × Jiaxing black) were used to study the effects of exogenous enzymes (including β -glucanase,xylanase and cellulase) supplemented to paddy-based diets on pig growth performance and digestion. With the supplementation of enzymes, average daily gain of pig was increased by 8.78%(P＜0.05), feed gain radio was decreased by 9.42%(P＜0.05), feed apparent digestibilities of crude protein, crude fat and crude fiber were increased by 17.32% (P＜0.01), 16.04% (P＜0.05) and 108.57%(P＜0.01),the viscosity of jejunum, and ileum contents were reduced by 7.08%(P＜0.01) and 6.78%(P＜0.01), numbers of E. coli in feaces and diarrhoea morbidity were decreased by 81.29%(P＜0.01 ) and 37.00%(P＜0.05), and the activities of protelytic enzyme and α-amylase in duodenal contents were enhanced by 99.07% (P＜0.05) and 18.38%(P＜0.05), respectively.
