Phylogenetic position of the saola (Pseudoryx nghetinhensis) inferred from cytogenetic analysis of eleven species of Bovidae.

Previous morphological and molecular analyses failed to resolve the phylogenetic position of the critically endangered saola (Pseudoryx nghetinhensis) with respect to its placement in Bovina (cattle, bison, and yak) or Bubalina (Asian and African buffaloes). In the present study, G- and C-banding, Ag-staining and FISH with 28S and telomeric probes was undertaken for 17 bovid species. An analysis of these data allowed us to identify 49 structural rearrangements that included autosomes, gonosomes and 17 different NOR sites.

[Dietary preferences of domestic ruminants (cattle, sheep, goats) grazing on natural Sahelian and Sudano-Sahelian ranges. IV. Attempted description of the diet by micro-histological analyses of samples collected by shepherds, esophageal boluses and feces from cattle and sheep].

A research program to study tropical pastures used by domestic livestock was implemented in Senegal. During field studies, numerous information was collected together with many samples with three main aims: pasture composition, diet composition and relationship between each other. The so-called method of epiderms, more often used in temperate areas, was chosen for analyzing and comparing the botanical composition of 105 samples, e.
