title: Sequence of amino acid limitation in triticale.
abstract: Nitrogen balance experiments were conducted on growing rats to study the sequence of limitation of amino acids in triticale protein. All essential amino acids were added to a triticale-based diet to adjust their total dietary levels to 110% of the requirement. From this complete supplement, individual amino acids were successively removed and nitrogen balance (NB) and biological value of protein (BV) were measured. Based on the extent of response to removal of amino acids, the sequence of limitation was estimated to be lysine, threonine, methionine and valine. The removal of histidine, isoleucine or tryptophan had no effect on NB or BV.
