Determinants of quality in soybean meal and its relationship to feed performance

Neoh S. B., . (2003) Determinants of quality in soybean meal and its relationship to feed performance. [Proceedings Paper]

The quality of soybean meal is usually determined by measuring its protein crude fibre and moisture content. Urease activity and KOH Protein Solubility KOHPS is used to determine whether the soybean meal is optimally processed. Recently Protein Dispersibility Index PDI was suggested as a better indicator for optimum processing. In vitro/vivo digestibility has been recommended as an indicator of amino acid availability. However recent studies has shown that the actual performance of various soybean meals in non-ruminant feeding can vary substantially despite having similar proximate analysis urease activity KOHPS and digestibility. Other studies on various feedstuffs has also shown that available nutrients especially certain amino acids such as lysine and cystine can be much lower than indicated by digestible nutrients. The challenge therefore is to find analysis methods that can accurately predict the actual performance of the soybean meal in animal feeding.

Abstract

The quality of soybean meal is usually determined by measuring its protein crude fibre and moisture content. Urease activity and KOH Protein Solubility KOHPS is used to determine whether the soybean meal is optimally processed. Recently Protein Dispersibility Index PDI was suggested as a better indicator for optimum processing. In vitro/vivo digestibility has been recommended as an indicator of amino acid availability. However recent studies has shown that the actual performance of various soybean meals in non-ruminant feeding can vary substantially despite having similar proximate analysis urease activity KOHPS and digestibility. Other studies on various feedstuffs has also shown that available nutrients especially certain amino acids such as lysine and cystine can be much lower than indicated by digestible nutrients. The challenge therefore is to find analysis methods that can accurately predict the actual performance of the soybean meal in animal feeding.
