[Chemical composition of feces from bovines, sheep and goats feeding from Sahelo-Sudanese natural or farming fields: its use for estimating the nutritive value of their diet].

The chemical composition of grazing cattle, sheep and goat feces is described according to animal species, type of range (natural pasture or fields after crops) and season in a sub-Sahelian environment. Nutritive value (organic matter digestibility and digestible crude protein) of forages can be estimated from some chemical fecal criteria.
