Figure 1

Experimental design showing four pre-weaning creep diet groups and eight post-weaning diet groups together with sow-reared control pigs. Creep feed was initiated 1 week prior to weaning and consisted of pelleted Phase 1 diets. Post-weaning diets consisted of either control basal diet (see Table 1) with additions of either 1% L-GLN (in all feed Phases 1–3) or 0.88% AminoGut in Phases 1 and 2 and 0.66% in Phase 3. Pigs were weighted at birth, weaning, (some at 1 wk post-weaning), 3 wk and 6 wk post-weaning. Selected pigs were euthanized (n = 7/trt) at 1 wk post-weaning for intestinal health measurements. Various treatment abbreviations are also summarized.
