Soybean meals of similar proximate analysis have been shown to perform differently in broiler feeding trials. The question is whether the differences can be attributed to higher available amino acids (AA) or higher metabolizable energy (ME) or both.
Three dehulled soybean meals from different origins were used to conduct a broiler chick feeding trial under either low AA or low ME conditions. The results showed that broiler chicks fed the AA deficient diet had significantly better feed conversion ratio than broiler chicks fed the energy deficient diet.
On soybean meal origins, chicks fed the diet using a commercial Malaysian dehulled soybean meal1 had significant higher body weight gain than chicks given diets containing commercial US dehulled soybean meal or commercial Argentinean dehulled soybean meal. No diet by soybean meal origin interactions were detected. This suggests that both available AA and ME content of soybean meals tested were important and contributed to better bird performance.
