The aim of the study was to evaluate the effects of fibre source (cassava residue, CR and sweet potato vines, SPV), particle size (1mm and 3mm screen size) and multi-enzyme supplementation (mixture of α-amylase, β-glucanase, cellulase and protease) on growth performance and the coefficient of total tract apparent digestibility (CTTAD) in weaning and growing pigs (Landrace×Yorkshire). The experimental diets were based on maize, fish meal, full fat soybean, soybean meal, soybean oil and CR or SPV. The dietary levels of CR and SPV were 200 and 350g/kg (as fed) in the post-weaning and growing period, respectively. The experiment was arranged…
