摘 要:
The following soybean meal samples were collected for analyzing:11 dehulled soybean meals from America,Brazil and China;57 regular soybean meals from thirteen provinces or cities in China and their soybeans from America,Brazil,Argentina and China.The results showed that,on the average,there were significant differences in crude protein and Ile,Lys,Met,Phe and essential amino acids(P<0.01),Leu,Thr and Val(P<0.05).The compositions of crude protein and Lysine(standardized DM 88%) were 46.72% and 3.08%,respectively;and were higher 1.64% and 0.09% than that of regular soybean meals(P<0.01),respectively.The prediction equations for indispensable amino acids were established from crude protein contents in soybean meal by linear regression.The regression coefficients of Lys,Thr,Trp,Met+Cys and Arg were 0.722,0.732,0.682,0.752 and 0.761(P<0.01),respectively.There were small deferences between the predicated and determined values of Lys,Thr and Arg,and those percentages of the difference(DIFF%)were 0.95%,0.30% and-2.19%,respectively.The result indicatd that the prediction equations of Lys,Thr and Arg established in this experiment were suitable to predict Lys,Thr and Arg values in soybean meal.
