Under the AR1 structure, the time effect was highly significant (F(6, 108) = 314.26, p < 0.001), confirming the expected progressive weight gain over the experimental period.

At the phylum level, the relative abundance of Bacteroidota in the L-cit group exhibited a numerical increase of 14.02%, whereas Proteobacteria decreased by 57.63%; although these changes did not reach statistical significance ( p > 0.05), they are consistent with the directional succession of the rumen microbiota during maturation.
The feed-to-gain ratio (F:G) of the L-cit group was reduced by 9.38% relative to the CON group, although this difference also failed to reach statistical significance ( p = 0.087). 3.2.
