Acute reduction in serum progesterone concentrations after feed intake in dairy cows
(2003-09-15)
This study tested the hypothesis that high feed consumption will acutely decrease circulating progesterone concentrations. In the first experiment, a Latin Square design was used to test whether feeding pattern would alter ...
Transfer coefficient measurements of uranium to the organs of Wistar rats, as a function of the uranium content in the food
(Elsevier B.V., 2001-06-01)
Groups of animals (Wistar rats) were fed with rations doped with uranyl nitrate at concentrations ranging from 0.5 to 100 ppm. The uranium content in the ashes of the organs was measured by the neutron-fission track counting ...
Atividade comparada da cefepima, cefpiroma e amicacina em amostras bacterianas hospitalares
(1999-01-01)
The objective of this study was to evaluate the in vitro activity of cefepime, cefpirome and amikacin against the most prevalent nosocomial bacteria. Initially a prospective study was designed to compare the bacterial ...
Digestibilidade da Matéria Seca, Proteína Bruta e Energia Bruta da Silagem de Milho associada ao Concentrado, por meio de ensaios in vivo e in vitro
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 1997-05-01)
A study was made to compare dry matter, crude protein and gross energy digestibility of corn silage, associated to concentrate, through in vitro and in vivo digestion techniques. A completely randomized design was used, ...
Effect of cationic micelles on the decomposition of alpha-aminophenyl cephalosporins
(Elsevier B.V., 2010-09-01)
The intramolecular rates of degradation of a-aminophenyl cephalopsorins were determined with and without hexadecyltrimethylammonium bromide (CTAB). Micellar-derived spectral shifts were used to measure the bind of the ionic ...

Influence of intraruminal infusion of propionic acid and forage to concentrate levels on intake, digestibility and rumen characteristics in young bulls
(Revista Brasileira de Zootecnia, 2017)
Sistemas de Alimentação com Livre Escolha e Semi Livre Escolha para Poedeiras
(Revista Sociedade Brasileira Zootecnia, 1997-03-01)
This research was carried out to verify the ability of laying hens to select food in order to meet their requirements for protein and energy. Ninety-six Hy-Line White laying hens, 45 weeks old, were allotted to a randomized ...
