The chemical treatment consisted of treating half of the wheat straw with 60 kg sodium hydroxide/t and the other with 60 kg sulphuric acid/t, and then mixing the two to give "Celephos". The digestibility coefficient of organic matter was 68.0 and 41.7 for "Celephos" and untreated straw, respectively. For a long term feeding trial, two mixtures were formulated (a) including 23 per T2 - Animal Feed Science and Technology ER -
