Impact of lemongrass and galangal as feed additives on performance of lactating Barki goats
Open accessAbstract
Background: The current study was carried out to investigate addition of lemongrass or galangal to diet and its effect of productive performance of lactating Barki goats.Materials and Methods: Thirty lactating Barki goats were divided into three groups (10 animals per each treatment), first group was fed control diet without additives, consist of Egyptian clover hay, corn silage and concentrate feed mixture (10:30:60% on DM basis, respectively) (Control); second group was fed control diet plus 4 g of lemongrass kgG 1 DM and the third group was fed control diet plus 4 g galangal kgG 1 DM.Results: The results showed that adding galangal increased propionate concentrations (p<0.05)compared with control (41.13, 37.75 and 39.46 mM for galangal, control and lemongrass, respectively); while, there were no differences (p>0.05) between treatments in acetate and butyrate concentrations.Ammonia concentration was higher (p<0.05) in lemongrass compared with other treatments (21.49, 15.92 and 15.91 mM for lemongrass, control and galangal, respectively).Milk yield were significantly increased (p<0.05) by adding lemongrass or galangal to the diets (825 and 771 g dayG 1 for lemongrass and galangal) compared with control (652 g dayG 1 ).Also, milk lactose content was significantly increased (p<0.05) in lemongrass compared with control (44, 40 and 39 g kgG 1 for lemongrass, control and galangal, respectively).Conclusion: It could be concluded that adding lemongrass or galangal the diet could enhance the performance of lactating Barki goat.

Most chemical additives either are noxious to host animals or present a temporary impact on methanogenesis.
“However, most chemical additives either are noxious to host animals or present a temporary impact on methanogenesis (24, 25).”
From Phytogenic Additives Can Modulate Rumen Microbiome to Mediate Fermentation Kinetics and Methanogenesis Through Exploiting Diet–Microbe Interaction (2020) · cites this paper as [25]
The Introduction (page not available) discusses concern about antibiotic residues in meat and milk, not harm to host animals from most chemical additives. The Discussion (page not available) mentions methanogenesis but does not say that chemical additives have only a temporary effect on it. Searches for additive toxicity and temporary effects found no passage supporting the claim. (LLM, conf=0.76)

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.
