Correlation coefficients between various characteristics of weaned piglets fed a control diet or diets adjusted to a total ergot alkaloid content of 16.8 mg/kg diet (Ergot 5-high; Ergot 15-high) (week 3 of experiment, n = 24). Liver function was tested by the 13C-ketoisocaproate breath test.

Abbreviations: LW = live weight, LWG = LW gain, GGT = γ-glutamyl transferase, ASAT = aspartat-aminotransferase, ALAT = alanine-aminotransferase, GLDH = glutamat-dehydrogenase, tmax (min) = time at the maximum 13C-exhalation, DOBmax (‰) = maximum delta over baseline value, t0.5 (min) = time when the half of the applied 13C is exhaled, cPDR30, 60, 120, 180 (%) = cumulative percent recovery of the applied 13C-dose after 30, 60 or 120 min. Bold printed correlation coefficients are significantly different from zero (p < 0.05).
