Evaluation of N-15 and purine bases as microbial markers to estimate ruminal bacterial nitrogen outflow in dairy cows
(Elsevier B.V., 2019-12-01)
The present study aimed to evaluate N-15 and purine bases (PB) as markers for ruminal bacterial nitrogen (N) outflow in dairy cows. Additionally, the effects of calcium salts of fatty acids (CSFA) in diets with different ...
An improved microbial synthesis of purine nucleosides
(Springer, 2000-07)
E. coli BL21 synthesized purine nucleosides from pyrimidine ones. A 94% yield of adenosine from uridine was reached within 1 h.
Avaliação de marcadores internos para estimativa de fluxo de digesta e proteína microbiana no duodeno de ruminantes
(Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em Zootecnia, 2014-02-26)
The aim of this study was to evaluate the use of internal markers to estimate duodenal flow of digesta and duodenal microbial protein synthesis in cattle and sheep. Data and samples of in vivo digestibility trials, eight ...
Métodos em nutrição de ruminantes: uso de índices fecais para estimar consumo e estimativa da síntese proteica microbiana ruminal
(Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em Zootecnia, 2009-02-13)
This study was carried out to evaluate methods in ruminant nutrition: use of fecal index to estimate intake and use of purine or purine derivatives to estimate rumen microbial protein synthesis. Data from three digestibility ...

Replacing maize with low tannin sorghum grains: lamb growth performance, microbial protein synthesis and enteric methane production
(Csiro Publishing, 2021-05-11)
Context. Sorghum (Sorghum bicolor (L.) Moench) grain with low tannin content may be suitable as an alternative to maize (Zea mays L.) grain in ruminant diets in terms of input costs and drought tolerance, and effects on ...
