sheep in the number of peaks and Shannon index values (Table 2). Moreover, although the donor sheep received the same
diet, there were differences among them in most of the fermentation parameters and microbial population measured in
the rumen fluids, which indicates the strong effect of donor animal. Differences in the fermentation parameters can be
explained by differences in the microbial populations and/or in their fermentative activities (Yánez-Ruiz ˜ et al., 2016), which
have been associated to va
