title: Effect of dietary fibre and caecectomy on the excretion of endogenous amino acids from adult cockerels.
abstract: 1. Eight diets based on maize starch and sucrose were prepared, containing ground maize husks or semi-purified wood cellulose, with 30, 60, 90 or 120 g fibre source/kg diet dry matter (DM). 2. The diets were precision-fed to 12 caecectomised and 12 intact adult male domestic fowls. The quantities of amino acids and faecal N excreted over the 48 h following each feeding were measured. 3. Diet had no influence on the quantities of endogenous amino acids or endogenous faecal N excreted. 4. A proportion of the amino acids and N of the maize husks and of endogenous origin appeared to be degraded or retained in the caeca of intact birds.
