Abstract

The aim of this experiment was to study the persistence in time of bacterial and methanogenic archaeal communities that establish in the rumen of lambs fed two different diets at weaning. Twenty ewes with single lambs were used in two phases. In phase I, 10 lambs had access only to grass hay (H group). The other 10 lambs had free access to concentrate and grass hay (C group). After 20 weeks, five lambs from each group were slaughtered and rumen samples were kept for analysis. In phase II, the remaining lambs were grouped together and fed grass plus concentrate for 4 months and then slaughtered, and rumen samples were collected for analysis. Terminal restriction fragment length polymorphism analysis showed a different bacterial and methanogen population established in the rumen of H and C lambs in phase I. These differences disappeared for methanogens after both groups were fed the same diet for 4 months; however, the total bacterial community remained different for the H and C samples. Our results suggest that some of the differences in the microbial populations that establish in animals fed different diets at weaning persist in the long term, which provides the possibility of programming the microbial populations in the adult animal.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
