Abstract: The aim of this study was to determine the effects of dietary Broken Rice (BR) and Cassava Chips (CC) on growth, nutrient digestibility and nitrogen retention in growing Kadon pigs in a parallel design. There were 4 measurement periods over the entire experiment lasting 56 days. Slaughter and meat characteristics were determined at the end of the experiment. For the entire experimental period there was no significant diet effect on Average Daily Gain (ADG), but ADG on the CC diet was on average 12% lower. In the pigs fed the BR diet the digestibilities of Dry Matter (DM), Organic Matter (OM), Crude Protein (CP), crude fat (EE, ethereal extract) and carbohydrates (NFE, nitrogen-free extract) were all higher. The higher digestibility of OM in the pigs fed on the BR diet was associated with a higher digestibility of gross energy in the diet. The higher digestibility CP in the pigs fed the BR diet was reflected by a smaller fecal Nitrogen (N) output, but N retention in the 2 groups of pigs was similar. This study shows that the carbohydrates in BR are more easily digested than those in CC. The higher amount of protein and the higher digestible carbohydrate content of BR, in combination with the actual prices and availability of BR and CC, will determine which carbohydrate source will be used in pig production, including on small-holder farms.
