Nelson Ruiz (Nelson Ruiz Nutrition LLC)   A set of 24 solvent extracted commercial soybean meal (CSBM) samples, which corresponded to the same lots of CSBM used in the field, were evaluated. The CSBM were from different origins (Argentina, Bolivia, Paraguay, Trinidad & Tobago, U.S.). The objective herein was to evaluate the relationship between KOH protein solubility (KOHPS, a measur ...

George Entz Precision nutrition and return on investment go hand in hand. If synthetic amino acids are too expensive to be added, it means that least-cost formulation is not taken them when they are offered in the formula, and consequently they are not contributing to decrease formulation cost. But precise nutrition is for the optimization of formulation that should be reflected in performance. M ...

Laura Popovich Yes, working with the AOCS (2020) method FFSB (as well as mechanically extracted soybean meal and solvent extracted soybean meal [SBM]) should be ideally lower than 5 TUI/mg, maximum 5.5 TUI/mg or expressed in mg/g using the same AOCS (2020) method maximum 3.5 mg/g. However, working with the European ISO 14902:2001, maximum 2.5 - 3.0 mg/g. These maxima are for inclusion levels of FF ...

Hello Dr. Cowieson, Do you mind commenting on the following assertion in a different Engormix forum? "Trypsin and chymotrypsin inhibitors will also inhibit the activity of trypsin-like proteases, such as serine proteases, see Morita (1996) Journal of Biochemistry, 119(4), 711–718. In that respect, you will probably fare better with aspartic proteases, which are resistant to trypsin (Kunitz) and ...

George Entz Soybean meal (SBM) is the predominant supplier of digestible amino acids in commercial poultry diets. I don´t know how predominant is SBM where you are or where you visit flocks. But if SBM is from 20% on in the formula of broiler feeds it is likely that you will see rapid feed passage in the excreta of any flock of broilers. SBM, to the best of my knowledge, continues to be at a ...
