Abstract

The aim of this work was to study the colonisation of the rumen by the three main microbial groups over the first 4 weeks of life and to assess to what extent the type of feeding management (natural with the mother, NAT, or artificial with milk replacer, ART) exerts an effect. Thirty pregnant goats carrying two fetuses were selected. At birth, one kid was taken immediately away from the doe and fed milk replacer (ART), while the other kid remained with the mother (NAT). Groups of four kids (from ART and NAT experimental groups) were slaughtered at 1, 3, 5, 7, 14, 21 and 28 days of life, resulting in seven sampling times. On the sampling day, after slaughtering, the rumen was weighed full and empty and the content sampled and pH measured. Aliquots of rumen digesta were immediately frozen for DNA and volatile fatty acid (VFA) analyses. The weight of the rumen was higher in NAT kids from Day 21 onward, while no difference was observed for rumen content volume. The three microbial groups (bacteria, archaea and protozoa) were detected from Day 1 in both experimental groups. The concentration of bacteria was higher in the rumen of NAT kids on Days 3, 5, 7 and 14 and of protozoa from Day 3 onward. This was reflected in greater VFA concentrations and lower pH in the rumen of NAT kids from Day 3. Our results confirmed substantial microbial colonisation from the first day of life in the undeveloped rumen. The feeding management (natural vs artificial) before weaning had an effect on microbial colonisation and rumen fermentation and, therefore, it should be considered when designing nutritional intervention strategies in early life.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Artificially reared calves have a near absence of protozoa in the rumen, as protozoa can only be inoculated in the rumen by direct contact with the dam or other mature animals through saliva.

    “Another distinctive feature between natural and artificial rearing systems is the near absence of protozoa in the rumen of artificially reared calves, as protozoa can only be inoculated in the rumen by direct contact with the dam or other mature animals through saliva (Abecia et al., 2014).”
  • Application of bromochloromethane (BCM) to young goat kids modified archaeal colonization of the rumen, and was linked to a reduction in methane emission of around 50%, with the effects persisting for 3 months after weaning.

    “It has been shown that application of bromochloromethane (BCM) to young goat kids modified archaeal colonization of the rumen, and was linked to a reduction in methane emission of around 50%, with the effects persisting for 3 months after weaning (Abecia et al., 2013, 2014).”

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.
