The supplementation of Gly to a low-CP C-SBM diet
along with l-Lys, l-Thr, l-Trp, dl-Met, l-Val, and l-
Ile resulted in growth performance similar to that of
pigs fed an 18% CP PC diet. The individual supplementation
of Glu or Arg did not elicit the same response.
This response indicates that the response obtained
with Gly supplementation was not as a result
of Gly providing N. The mechanism of action whereby
Gly restores growth performance in a low-CP C-SBM
diet is presently not known.
