Abstract：The objective of this experiment was to study the effects of diets with two fiber levels on growth performance, apparent digestibility of nutrients and colonic volatile fatty acid contents and microorganism numbers in 16 to 23 kg Tianjin black pigs. Tianjin black pigs with the similar health status and genetic background, an average weight of (16.18±0.35) kg were selected in this study and providing two dietary fiber levels of 9.7% and 15.3%. In Exp.1, twenty-four black pigs were randomly assigned into 2 groups, and each group had six replicates with two pigs per replicate. This experiment lasted for 28 days. The objective of this experiment was to study the effects of diets with two fiber levels on growth performance, colonic volatile fatty acid contents and microorganism numbers. In Exp.2, six pigs were assigned into one of 3×2 Latin squares to determine the nutrient digestibility of nutrients using total feces collection method. Experimental period lasted for 12 days, consisting of a 7-day preliminary period and a 5-day collection of feces and urine period. The objective of this experiment was to study the effects of diets with two fiber levels on nutrient digestibility of nutrients. The results showed that compared with the 9.7% fiber group, increasing the dietary fiber level to 15.3% significantly reduced the average daily weight gain of black pigs (P<0.05), significantly reduced the apparent digestibility of crude protein, digestible energy, arginine, valine and cysteine (P<0.05), and increased the feed to gain ratio and the colonic acetic acid content (P<0.05). In conclusion, the effect of diet with 9.7% fiber level on growth performance and apparent digestibility of nutrients is better than that of diet with 15.3% fiber level for 16 to 23 kg Tianjin black pigs.
