Jang, Y. D. and Kim, Y. Y. 2013. Short Communication: Energy values and apparent total tract digestibility coefficients of copra meal and palm kernel meal fed to growing pigs. Can. J. Anim. Sci. 93: 517–521. To determine energy values and coefficients of apparent total tract digestibility (CATTD) of copra meal (CM) and palm kernel meal (PKM), 24 growing pigs were fed a corn–soybean meal basal diet and the basal diet replaced by 300 g kg−1 of either CM or PKM. Copra meal had higher CATTD of gross energy (12%), dry matter (DM; 13%), neutral detergent fiber (16%), acid detergent fiber (23%), and crude fiber (79%; P<0.05) than PKM. Copra meal had a slightly higher digestible energy (DE) value than PKM (14.08 vs. 13.01 MJ kg−1 DM; P=0.067), but metabolizable energy (ME; 13.33 vs. 12.83 MJ kg−1 DM), net energy (7.97 vs. 7.36 MJ kg−1 DM), and ME:DE ratio did not differ between CM and PKM. Therefore, compared with PKM, CM can be a better source of dietary energy in swine diets as evidenced by higher CATTD of energy and fiber components.

Abstract There is a lack of nutrition information on local feeds protein in Indonesia, especially to determine protein fraction of dairy feed. The objective of this study was to determine rumen degradable protein (RDP) of local feeds in dairy cattle using in sacco method. The local feeds are copra meal, palm kernel meal, coffee husk, tofu waste, soy-sauce waste, brewer waste, and habbatussauda waste. Two ruminal fistulated male Frisian Holstein were used to determine rumen degradable protein using in sacco method. The parameters observed include the estimated kinetic parameters, effective degradability (ED), and RDP. The parameters were evaluated with analysis of variance using SAS University software. The result showed that tofu waste and habbatussauda waste had high potential rapid degradation of CP following by brewer waste, palm kernel waste, soy-sauce waste, copra meal, and coffee husk. Habbatussauda waste had higher RDP followed by brewer waste, tofu waste, copra meal, palm kernel meal, soy-sauce waste, and coffee husk. There was a positive correlation between RDP and crude protein content, and a negative correlation between RDP and crude fiber. It is concluded that local feeds have various characteristics of quality feed protein, which is shown by rumen degradable protein and rumen undegradable protein.
