Abstract

The experiments were conducted to determine AMINO ACIDs digestibility of SOYBEAN MEAL, using two bioassays as collecting ILEUM content and collecting FECAL in male broiler chickens. The experiments were conducted (with 100 birds) at 21 and 42 days of age, using metabolical cages, as a CRD with 4 replications (2 birds per each replicated). AMINO ACID digestibility was determined using titanium oxide as a marker. The birds were killed on day 42 and the contents of the ILEUM were collected to determine AMINO ACID digestibility. The results of experiments indicated that industrial procedure had effects on the SOYBEAN MEAL digestibility. Mean values of apparent and true digestibility of SOYBEAN MEAL for FECAL assay were 78.57 and 79.57 percent and for ILEUM bioassay 71.39 and 72.28 percent respectively. The results have shown that AMINO ACID digestibility of SOYBEAN MEAL was approximately 10.08 percent higher for excreta collection bioassay compared to ILEUM assay. The result of data confirms that systeine, aspartic acid and glutamic acid digestibility were higher than other AMINO ACIDs such as isoleucine and valine of SOYBEAN MEALs for two ages (21 and 42 days) or both bioassays respectively.
