Effect of heat damage and assay methodology on digestibility and bioavailability of amino acids in cottonseed and soybean meals

Experiments were conducted to evaluate the effect of assay methodology and heat damage on amino acid (AA) bioavailability for chick growth. Performance of chicks fed corn-cottonseed meal (CSM) diets formulated on a total AA basis was inferior to performance of chicks fed a corn-soybean meal (SBM) diet. Further evaluation showed that the true digestibilities of AA in CSM were lower than those in SBM. Consequently, growth performance of chicks fed up to 20% CSM on a digestible AA basis was found to be equivalent to that of chicks fed the corn-SBM diet. However, dietary levels of 30 or 40% CSM depressed performance even on a digestible AA basis.
