ABSTRACT
The study aimed at determining the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of essential amino acids (EAAs) in paddy rice, broken rice and rice bran fed to growing pigs. A total sixteen barrows of 35 kg were randomly allocated into one of 4 dietary treatments namely NFD (animals fed nitrogen-free diet), and paddy rice, broken rice and rice bran, used chromic oxide as an indicator. Pigs were fed for 14 days and on day 14th, all animal were killed to collect the ileal digesta for chemical and amino acid analyses. Results show that total basal ileal endogenous loss of EAAs is 1.22 g/kg dry matter intake; the average AID and SID values of EAAs in broken rice are highest (81.72% and 83.57%, respectively), and lowest in paddy rice (72.69% and 74.85%, respectively). The values of AID and SID of most essential amino acids are higher in broken rice than in paddy rice and rice bran. In conclusion, the broken rice, rice bran and paddy rice contained readily digestible essential amino acid and SID values are very high.
