Popis:	In two separate conventional metabolism trials, each involving eight 13 kg liveweight pigs given a barley-based diet, mean faecal recoveries (±SD) of chromic oxide added to the diet and naturally occurring acid-insoluble ash of 85.3 (±6.19) and 98.2 (±4.03) % respectively, were obtained. Total faeces collection gave significantly (P 0.05) in nutrient digestibility for total collection compared with acid-insoluble ash. There were only very small differences in nutrient digestibilities calculated by reference to the concentration of each respective marker in aliquots of the total faeces excreted and composite 6-day grab samples of faeces. Based on the correlation between organic matter digestibility determined by reference to the chromium content of cumulatively bulked daily grab samples of faeces, it was dee...
