W.  aPlant fragments in the feces of bighorns as indicators of food babits.h[electronic resource]  c1973  aAbstract: Plant fragment compositions in the rumens and pellets formed in colons of bighorn sheep (Ovis canadensis) were determined by microscopic technique for four bighorn sheep collected in the winter, 1971. Paired t-tests were used to compare frequencies of occurrence of corresponding plant fragments identified in rumens and the colons. No statistically significant differences were noted, indicating that if plant fragments in the rumens and plant fragments in the colons came from the same plant population, the relative number of plant fragments of each kind of plant remains similar in passing through the digestive process. It is suggested that digestion reduces the mean weight of fragments rather than eliminating the whole fragment for the kinds of plants commonly found in the diets of bighorn sheep. The microscopic analysis of fecal samples from bighorn sheep is a very useful index to food habits.  aRuminant nutrition  aSheep feeding  aDieta  aNutrição Animal  aOvino  aRúmen  aAnálise fecal  aFecal analysis1 aHANSEN, R.
