Analysis of the rumen bacterial diversity of goats during shift from forage to concentrate diet.
Three different culture-independent methods used in this study show that high proportion of concentrate in goat diet does not induce any serious disturbance of their rumen ecosystem and indicate the good adaptive response of caprine ruminal bacteria to incorporation of corn into the diet. Expand
Rumen development and blood metabolites of Criollo kids under two different rearing systems
The alternative rearing system improves the physical and metabolic development of the rumen and promotes the transition of kids from pre-ruminant to ruminant and in dry periods with shortage of forage, this system should be used. Expand
Growth and economic performance of kid production under different rearing systems and slaughter ages in arid areas of Argentina
It would be advisable to raise the kids naturally with goat milk and increase the age of slaugther, as long as consumers accept these older animals without decreasing the selling price of meat. Expand
Seasonal changes in feed intake, diet digestibility and diet composition by lactating and non‐lactating goats browsing in a semi‐arid rangeland of Argentina
The paper was presented at the 87th Congress of the Consejo Nacional de Investigaciones Cientificas y Tecnicas - Mendoza with a focus on Argentina, where it was the first time the paper had been presented at this level. Expand
Isolation of Pseudobutyrivibrio ruminis and Pseudobutyrivibrio xylanivorans from rumen of Creole goats fed native forage diet
The identification of bacterial strains involved in the rumen fermentation helps to explain the ability of these animals to digest fiber plant cell wall contained in native forage species. Expand

The results indicate that the virulent strain not only occupies two different kinds of compartments but also alters the endocytic pathway of the cell it parasitizes, unlike what has been reported for non-professional phagocytes, like HeLa cell. Expand
Selective behavior of Creole goats in response to the functional heterogeneity of native forage species in the central Monte desert, Argentina
Grazing goats showed differences in the patterns of diet selec- tion related to changes in forage availability, and goats selected supplementary food mixtures (mixed diet) and tannins were not considered dissuasive but, rather, were maintained below a certain threshold. Expand
Degradation and utilization of hemicellulose from species forage by Pseudobutyrivibrio ruminis and Pseudobutyrivibrio xylanivorans.
Identification of GH10 xylanases in strains 2 and Mz5 of Pseudobutyrivibrio xylanivorans
Identifying xylanase-encoding genes and activity of these enzymes are a step toward understanding possible functional role of P. xylanivorans in the rumen ecosystem and contribute to providing an improved choice of enzymes for improving fiber digestion in ruminant animals, agricultural biomass utilization for biofuel production, and other industries.

Pseudobutyrivibrio xylanivorans adhesion to epithelial cells.
The results indicate that a multiplicity of infection of 200 CFU/cell allows the highest bacteria to cell binding ratio, with a lower percentage of auto-agglutination events. Expand
