The effects of different fibre sources in pig diets on growth performance, ammonia (NH3 ), hydrogen sulphide (H2 S), greenhouse gas (GHG) emissions and slurry characteristics was studied on 20 crossbred pigs [Duroc x F1 (Landrace x Yorkshire)]. The experimental diets included one low-fibre (LF) diet without maize distiller’s dried grains with solubles (DDGS), brewer’s grain (BG) and coconut cake (CC) and 3 high-fibre (HF) diets with maize DDGS or BG or CC. The experiment was conducted according to a completely randomized design with 5 replications and lasted 62 days. In the growing period and the overall, pigs fed diets LF and HF-DDGS had higher average daily gain (ADG) compared to pigs fed diets HF-BG and HF-CC (P 0.05), while N and P excretions (g/head/day) were greater for diet HF-CC than for diet LF (P 0.05). In both periods, CH4 emission was lower in diet LF than in diet HF-BG and HF-CC (P 0.05), while NH3 emission was higher for pigs fed diet LF than pigs fed HF-BG and HF-CC (P 0.05). The H2 S emission was not affected by diets in both periods. In conclusion, different fibre sources in pig diets may be a practical method to alter growth performance, slurry characteristics and NH3 , GHG emissions.
