Coprophagy in iron-deficient rats: II. 2 novel methods of prevention

Abstract

2 novel methods of coprophagy prevention were used in iron-deficient rats to measure their effect on haemoglobin regeneration during the feeding of ferrous sulphate or several soya proteins. Neck collars produced considerable weight loss and depression in food intake compared to aluminium anal cups which were tolerated well. Both methods of coprophagy prevention reduced iron availability from a range of soya proteins and ferrous sulphate and it is suggested that the practice of coprophagy in iron-deficient and possibly iron-replete rats may overestimate iron (and possibly other mineral) absorption (retention) studies. © 1984, Royal Society of Medicine Press.
