Urine and faeces production, water intake and body condition were investiga
ted in 19 pregnant gilts fed a concentrated (CONC: 2 kg d(-1), 2.2% CF) or
high-fibre diet (HF: 3.6 kg d(-1), 20.4% CF). Gilts fed HF drank less (P <
0.05) than CONC, but urine excretion did not differ significantly. More fae
ces were excreted by HF than CONC (P < 0.001), with similar dry matter cont
ents. Total daily manure production, body weight and backfat thickness were
similar among treatments.
