Amino acid digestibility of five samples of canola meal fed to ileal-cannulated grower pigs

An abstract of a study by Le Thanh et al evaluating the standardized ileal digestibility (SID) of CP and AA in 5 Brassica napus canola meal (CM) samples from 5 Western Canadian crushing plants is presented. On DM basis, the soybean meal (SBM) and 5 CM samples contained 51 and 39-45% CP; 7 and 24-27%...

Description
Summary:An abstract of a study by Le Thanh et al evaluating the standardized ileal digestibility (SID) of CP and AA in 5 Brassica napus canola meal (CM) samples from 5 Western Canadian crushing plants is presented. On DM basis, the soybean meal (SBM) and 5 CM samples contained 51 and 39-45% CP; 7 and 24-27% NDF; and 4.70 and 4.73-4.82 Mcal/kg GE, respectively. The SID of Lys, other indispensable AA (except His), dispensable AA (except Glu) was greater (P < 0.05) for SBM than for the 5 CM samples. Among the 5 CM samples, the SID of Lys ranged from 75 to 80% (P < 0.05), of Thr from 70 to 76% (P < 0.05), and of Met from 82 to 86% (P < 0.05). In conclusion, the SID of most AA was lower in CM than in SBM likely due to the greater fiber content in CM. The SID of AA differed among the 5 CM samples, but could not be associated to changes in chemical composition. The range in quality of CM is sufficient to warrant establishment of rapid quality evaluation measurements to predict AA quality of CM.
