| We studied the effects of including in the diet a mono component serine protease (PRO; RONOZYME ® ProAct, DSM Nutritional Products, Basel, Switzerland) on apparent ileal digestibility (AID) of DM, CP and AA of soybean meals (SBM) of USA (n=3), Brazil (n=3) and Argentina (n=3) origin, in 22 d - ol d broilers. The 6 experimental treatments formed a 3 x 2 factorial with 3 SBM origins (USA, BRA and ARG) and 2 levels of PRO (0 and 200 mg/kg to give 0 and 15,000 PROT units/kg feed). Three different batches of each SBM were nested within each of the 3 SBM origins. Each of the 6 trea t- ments were replicated 24 times (8 times per batch). The experimental unit was a cage with 8 broilers. Birds were fed a commercial corn - soybean meal diet from 1 to 18 d of age followed by the experimental diets that consisted of a mixture of 42.6% SBM and 57.4% of a nitrogen free diet for 4 d. The supplementation with PRO improved the AID of all the AA (ranging from 0.5 to 1.6 percentage units) but the differences were not significant. The AID of DM, CP and Lys was 1.5%, 1.1% and 1.0% higher in bird fed PRO than in birds fed the un - supplemented diets (P > 0.10). In general, the AID of DM, CP and AA was higher for the USA meals than for the South America meals but the differences were not signif i- cant. In addition, the AMEn of the d iets increased by 1.1% as an average, with PRO inclusion (P < 0.001). In summary, the inclusion of RONOZYME® ProAct increased numerically the AID of all the AA of the SBM and the DM of the diets but the differences were not significant. | |
