The objectives of this study were to investigate the variation of nutrient composition in oilseed meals and to develop prediction equations for amino acid concentrations. Energy and nutrient contents were determined in a total of 1,401 feed ingredient samples including 184 copra expellers and 356 copra meal samples produced in 2 countries (Indonesia and Philippines), 31 corn distillers dried grains with solubles samples produced in 2 countries (China and USA), 567 palm kernel expellers and 85 palm kernel meal samples produced in 2 countries (Indonesia and Malaysia), and 178 soybean meal samples produced in 4 countries (Argentina, China, India, and USA). Data were analyzed using the MIXED procedure of SAS (SAS Inst. Inc., Cary, NC, USA). The regression procedure of SAS was used to generate the prediction equation for the lysine concentration using the CP concentration as an independent variable. The GE concentrations in soybean meal produced in Argentina were greater (4,400 vs. 4,128 kcal/kg; P < 0.05) compared with that in China. The CP (46.2 vs. 45.2%) and methionine (0.65 vs. 0.55%) concentrations in soybean meal produced in USA were greater ( P < 0.05) compared with that in China. For corn distillers dried grains with solubles, the GE concentration was greater ( P < 0.05; 4,753 vs. 4,564 kcal/kg), but the CP (26.5 vs. 28.8%) and Ca (0.03 vs. 0.08%) concentrations were less ( P < 0.05) in USA compared with China. The CP concentration in copra meal produced in Malaysia was greater (16.0 vs. 15.1%; P < 0.05) than that produced in Indonesia. The CP (15.8 vs. 14.9%) and lysine (0.35 vs. 0.32%) concentrations of palm kernel expellers produced in Malaysia were greater ( P < 0.05) compared with that produced in Indonesia. The CP (16.0 vs. 15.1%) and P (0.62 vs. 0.57) concentrations of palm kernel meal were also greater in Malaysia compared with Indonesia. The prediction equations for amino acid concentrations (% as‐is basis) in the oilseed meals are: lysine = −1.07 + 0.079 × CP (root mean square error = 0.264, R 2 = 0.925, and P < 0.001); methionine = 0.047 + 0.012 × CP (root mean square error = 0.125, R 2 = 0.574, and P < 0.001); cysteine = −0.068 + 0.017 × CP (root mean square error = 0.147, R 2 = 0.654, and P < 0.001); threonine = −0.303 + 0.044 × CP (root mean square error = 0.110, R 2 = 0.957, and P < 0.001). In conclusion, energy and nutrient compositions vary in the oilseed meals depending on the producing countries. The crude protein concentration can be a good independent variable for estimating lysine and threonine concentrations in oilseed meals.
