Trial 1 assessed the palatability of diets containing (<jats:italic>a<\/jats:italic>) 5 g chromic oxide\/kg, (<jats:italic>b<\/jats:italic>) 1 and (<jats:italic>c<\/jats:italic>) 5 g titanium dioxide\/kg at two levels of feeding. The results indicated that there were slight problems in terms of period of feed consumption associated with diets (<jats:italic>a<\/jats:italic>) and (<jats:italic>c<\/jats:italic>), but that these effects were transitory and disappeared following acclimatization, although higher levels of feeding may compound the problem. Trial 2 estimated N balance, faecal apparent digestibility of amino acids as determined by both total collection and ratio of markers, ileal apparent digestibility of amino acids and recovery of markers using diets containing (<jats:italic>a<\/jats:italic>) 1 and (<jats:italic>b<\/jats:italic>) 5 g Cr<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>\/kg, (<jats:italic>c<\/jats:italic>) 1 and (<jats:italic>d<\/jats:italic>) 5 g TiO<jats:sub>2<\/jats:sub>\/kg. An additional assessment of acid-insoluble lignin present within the diet was also undertaken. Cr<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub> was associated with the lowest recovery, whilst calculations based on TiO<jats:sub>2<\/jats:sub> gave lower standard errors. Trial 3 examined diurnal variation in digesta sampling and its effect on faecal apparent digestibility of N and amino acids. There were no evident effects. In general, it was concluded that the most appropriate marker to use in studies of this nature was TiO<jats:sub>2<\/jats:sub> at a rate of 1 g\/kg.<\/jats:p>","DOI":"10.1079\/bjn19920129","type":"journal-article","created":{"date-parts":[[2005,9,15]],"date-time":"2005-09-15T01:16:17Z","timestamp":1126746977000},"page":"729-739","source":"Crossref","is-referenced-by-count":123,"title":["Evaluation of inert markers for the determination of ileal and faecal apparent digestibility values in the pig"],"prefix":"10.1017","volume":"68","author":[{"given":"S.","family":"Jagger","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Wiseman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
