Twenty 5 barrows (initial BW = 8.81 kg ± 1.52 kg) were used to determine the apparent (AID) and standardized (SID) ileal AA digestibilities in rice polished and broken (RB) with or without multi-carbohydrase (Carb) and phytase (Phy) enzyme supplementation. Pigs were allotted in a completely randomized design to 5 treatments with 5 replicates. The experimental diets consisted of RB as the sole source of protein without enzymes, with Carb, Phy or Carb+Phy and a low-protein diet (5% casein) used to quantify endogenous AA losses. All diets contained chromic oxide (0.3%) as indigestible marker. Pigs were given their daily feed allowance at a rate of 4.5% of BW determined at the beginning of each experimental period. Animals were slaughtered at d 43 and ileal contents collected. The data were analyzed using the GLM (SAS Inst. Inc., Cary, NC), and means were compared by Tukey’s test. The phytase, singly or in combination with multi-carbohydrase, improved AID and SID (P < 0.05) of histidine, leucine and lysine of polished and broken rice, while singly carbohydrase improved only AID and SID (P < 0.05) of histidine. Coefficients of AID and SID of AA in RB (without enzymes) were, respectively: Arg, 0.662 and 0.841; His, 0.626 and 0.769; Ile, 0.596 and 0.792; Leu, 0.700 and 0.790; Lys, 0.663 and 0.775; Met, 0.710 and 0.808; Phe, 0.721 and 0.843; Thr, 0.492 and 0.650; Val, 0.630 and 0.811; Ala, 0.509 and 0.613; Asp, 0.618 and 0.735; Glu, 0.667 and 0.778; Pro, 0.623 and 0.853; Ser, 0.404 and 0.716; Tyr, 0.744 and 0.865. In general, these results were lower than those in NRC (2012). Underestimated digestibility coefficients may be related to animal ages in the present study, since most of the studies in literature were obtained from pigs with higher weights. The phytase, singly or combined with carbohydrase, improves the digestibility of His, Leu and Lys in rice polished and broken.
