Abstract

Ileal and total tract digestibility of low and high-fibre diets (100 and 200 g/kg neutral detergent fiber), with or without enzyme supplementation (mixture of cellulase, -glucanase, -amylase and protease) was determined in piglets of two breeds weaned at 30 days of age. The breeds were local (pure-breed Mong Cai, MC) and exotic (Landrace x Yorkshire, LY). The experimental diets were based on maize meal, soybean meal, fish meal, cassava residue meal, and rice bran. Cassava residue meal and rice bran were the main fibrous feeds in the high-fibre diet. The experiment was arranged according to a 2 x 2 x 2 factorial, completely randomized design with 4 replications, and lasted for 30 days. The coefficient of ileal apparent digestibility (CIAD) was measured by analyzing ileal digesta collected from piglets killed at 60 days of age. The coefficient of total tract apparent digestibility (CTTAD) was measured by analyzing faecal samples collected for 5 consecutive days immediately before the experiment finished. The CIAD and CTTAD of organic matter, crude protein, crude fibre, neutral detergent fiber, acid detergent fiber and amino acids in the high-fibre diet were lower than in the low-fibre diet (P<0.01). The CIAD of nutrients and amino acids was similar (P>0.05) between MC and LY, while the CTTAD of nutrients was higher for the MC than for LY (P<0.05). Enzyme supplementation of the high-fibre diet improved daily gain and the digestibility of all dietary components at the ileum and in the total tract (P<0.05), but there was no effect of enzyme supplementation of the low-fibre diet (P>0.05)
