Spot urine collection: A valid alternative to total urine collection for metabolomic studies in dairy cattle [PDF]

open access: yesJournal of Dairy Science, 2022
Urine is a highly suitable biological matrix for metabolomics studies. Total collection for 24-h periods is the gold standard as it ensures the presence of all metabolites excreted throughout the day. However, in animal studies, it presents limitations related to animal welfare and also due to alterations of the metabolome originating from the use of ...

Collective Asymmetric Total Synthesis of Cylindricines

open access: yesOrganic Letters, 2023
Collective asymmetric total synthesis of marine tricyclic alkaloids, cylindricines A–H, and the proposed structures of cylindricine I and J, was achieved in a concise manner from a single common spirocyclic pyrrolidine intermediate. A tandem chemoselective oxidation/intramolecular aza-Michael addition/epimerization was exploited to complete the ...

Sources of acid insoluble ash as marker of corn digestibility in broilers

open access: yesSemina: Ciências Agrárias, 2022
The objective was to evaluate three sources of acid insoluble ash (AIA) (celite, kaolin, and sand), as indicators, to determine the apparent metabolizable energy of corn on a natural matter (AME) basis, dry matter digestibility coefficient (DMDC), and ...

Collective total syntheses of cytochalasans and merocytochalasans

open access: yesTetrahedron Chem, 2022
Cytochalasans are an important class of fungal metabolites displaying remarkable structural diversity and significant biological activity. Historically, considerable effort has been devoted toward the synthesis of cytochalasans. Comparably, merocytochalasans, an array of more complicated molecules biosynthetically derived from cytochalasans and ...

Digestibilidade e balanço de nitrogênio de rações com diferentes teores de proteína degradável no rúmen e milho moído como fonte de amido em ovinos Digestibility and nitrogen balance of sheep diets containing different levels of ruminal degradable protein and ground corn

open access: yesRevista Brasileira de Zootecnia, 2006
O objetivo neste trabalho foi avaliar a digestibilidade aparente de rações com diferentes teores de proteína degradável no rúmen (PDR) e fonte de amido de baixa degradabilidade ruminal (milho moído) em ovinos.

Creatinine excretion and relationship with body weight of Nellore cattle

open access: yesRevista Brasileira de Zootecnia, 2012
The objective of this study was to estimate the urinary creatinine excretion by the shrunk body weight (SBW). In experiment I, 32 Nellore bulls with initial body weight of 259±24.9 kg and 14±1 months-old were used.

Energetic and nutrient metabolizability values of corn obtained with nutritional corrections for broilers

open access: yesRevista Brasileira de Zootecnia, 2012
The experiment was carried out to evaluate the influence of nutritional correction on the partial diet replacement or pure-food methodology to determine the energy values (apparent metabolizable energy - AME and nitrogen-correct apparent metabolizable ...
