Abstract

In order to compare economics of soybean meals (SBMS) imported from Brazil and the U.S., a feeding trial was conducted with 480 commercial broiler chicks (Abor Acres strain) for 38 days. The Brazilian SBM was brownish in color and the protein solubility in 0.2 % KOH solution was 63. 4 %. The U.S. SBM, on the other hand, was a dehulled SBM, and uniform in color (light yellow) and particle size. The protein solubility value of the latter was 76.6 %. Two dietary protein levels (19 % and 21 %) were used for each source of SBM (2x2 factorial). Chicks fed diets containing the U.S. SBM grew significantly faster (P<0.05) and utilized feed more efficiently than chicks fed diets containing Brazilian SBM. Chicks fed diets containing 21 % CP showed better growth performance and profitability than those fed the 19 % CP diets. The price of the U.S. SBM was higher but the feed cost per unit gain was lower than the Brazilian SBM. Results suggest that there are over-cooked SBMs being traded on the Korean rnarket, and attention should be given to not only the price but also the quality of SBMs.
