An improved multi-element measurement of mineral absorption in the piglet utilizing the fecal monitoring technique

The fecal monitoring technique for measuring the absorption of Zn, Mn, Se, and Fe was studied in eight male piglets (mean±SEM birthweight (bw)=1695±50 g) using high resolution gamma spectrometry. Four d old piglets were fed a complete liquid milk diet for five d prior to the orogastric administration of an isotope dose (75Se,54Mn,59Fe, and65Zn) equilibrated with the liquid milk diet.51CrCl3 was used as a fecal marker but was found to be …
