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 ...

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

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

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.
