Abstract

Abstract Background The use of synthetic compounds as growth promoters in animal production, is now limited or even banned by health agencies globally due to human safety concerns. In feedlot cattle, when using high grain diets, it is necessary to supplement the diet with compounds capable of modulating the rumen in order to reduce the incidence of acidosis and improve growth. In this context, natural substances have become promising substitutes. The objective of this study was to evaluate the effects of a natural additive blend (NA) on animal performance, the rumen microbiome and ingestive behavior in 40 young bulls.Results The initial and final average body weight was similar (P > 0.05) for all diets, although average daily gain increased linearly (P < 0.01) when NA was fed. However, feed efficiency improved linearly (P < 0.05) by including NA in the diet. Principal volatile fatty acid: acetic, butyric, isovaleric and valeric decreased linearly (P < 0.02) following NA addition. Similarly, NA addition linearly decreased (P < 0.02) the acetate/propionate ratio. The propionate and isobutyric acid concentrations showed a positive quadratic effect (P < 0.05). Furthermore, NA addition reduced ammonia concentrations (P < 0.001) and ruminal pH was not affected (P > 0.05) by the diets. The rumen microbiome was significantly different between beef cattle fed the different treatments (P < 0.05), with a reduction in the archaea, and within the Clostridium, Robinsoniella, Acidaminococcus, Acetitomaculum, Succinimonas and Weissella (P < 0.05) seen when NA was fed. The functional capacity of the rumen microbiome was affected following NA supplementation. Overall, we observed Aldehyde oxidase/xanthine dehydrogenase, molybdopterin binding; RecG, N-terminal antiparallel four helix bundle; Transposase, ISC1217; Restriction endonuclease, type II, XamI; Acyl-protein synthetase, LuxE; ABC-2 transporter; which could be related to the natural additives mechanism of action.Conclusions Animal performance was improved in a dose-dependent manner by natural additive addition to the diet of bulls. These beneficial effects are correlated to changes in the rumen microbiome. Our findings suggest that the natural additive blend used in this study could be used as an alternative natural substitute to synthetic antibiotics for animal production.

  • Dietary changes are a major factor influencing the dynamics of rumen microbial populations and resultant metabolic shifts leading to significant changes in ruminant production.

    “Dietary changes have been reported as a major factor that influences the dynamics of rumen microbial populations and resultant metabolic shifts leading to significant changes in ruminant production (142, 143).”

    The Rumen bacterial diversity and abundance and Animal performance sections (pages not provided) report changes in rumen microbes, fermentation measures, daily gain, and feed efficiency after natural additives were added to young bulls’ diets. The Conclusions link improved performance to microbiome modulation, but the paper does not establish that dietary changes generally are a major factor across ruminants. (LLM, conf=0.85)

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.
