Aspects physio-pathologiques de la thiamine (vitamine B1) chez les ruminants

open access: yesINRAE Productions Animales, 1994
Cette revue envisage d’abord la production microbienne, l’absorption et l’utilisation métabolique de la thiamine chez le ruminant sain ainsi que les effets d’une synthèse insuffisante de thiamine sur l’activité microbienne du rumen.

Quantitative analysis of ruminal methanogenic microbial populations in beef cattle divergent in phenotypic residual feed intake (RFI) offered contrasting diets [PDF]

open access: yes, 2014
peer-reviewedBackground Methane (CH4) emissions in cattle are an undesirable end product of rumen methanogenic fermentative activity as they are associated not only with negative environmental impacts but also with reduced host feed ...

Efecto de la zeolita nanoestructurada con ácido lipoico sobre los parámetros productivos y rendimiento de la canal en el pollo de engorda

open access: yesRevista Mexicana de Ciencias Pecuarias, 2018
Los antioxidantes se emplean rutinariamente como aditivos alimenticios en la producción de pollos de engorda. Entre ellos destaca el ácido alfa lipoico (AAL), ya que su adición en la dieta (40 mg kg-1) mejora la ganancia de peso y la conversión ...

Motility of the reticulum and rumen of sheep given juice-extracted pasture [PDF]

open access: yes, 1982
1. Sheep were fed on different diets of juice-extracted herbage to determine what effect juice-extraction had on reticulo-rumen motility. 2. The frequency of A and B sequences of contraction of the reticulo-rumen were recorded during eating, rumination ...

Measurement of methane emission from sheep by the sulphur hexafluoride tracer technique and by the calorimetric chamber: failure and success

open access: yesAnimal, 2008
The aim of this study was to evaluate the sulphur hexafluoride (SF6) tracer technique for methane (CH4) emission measurement in sheep. Ten cryptorchid Romney sheep were involved in two indoor trials (T1 and T2), where daily CH4 emissions were ...

Cold Orthogonal Translation: A Psychrophilic Pyrrolysyl‐tRNA Synthetase Boosts Genetic Code Expansion in E. coli

open access: yesAdvanced Science, EarlyView.
ABSTRACT Orthogonal translation systems (OTSs) enable site‐specific incorporation of non‐canonical amino acids (ncAAs) and are central to genetic code expansion. Current engineering strategies typically rely on hyperstable aminoacyl tRNA synthetase (aaRS) scaffolds to tolerate destabilizing mutations required for substrate diversification.
