¹Formate recovered from manufactured feed presented as a percentage of feed.

²Amasil NA recovered from manufactured feed presented as a percentage of feed.

³Percentage of recovered of Amasil NA from manufactured feed supplemented with Amasil NA. Percentage was based on recovered vs. what was supplemented in diet (0.25 or 0.5%).
