Abstract

A completely randomized trial was conducted in order to evaluate the hydrogen ion concentration (pH), total titratable acidity and methylene blue reduction time test in rumen fluid of cross bred and raced goats, grazing on grasslands and rangelands of semi arid regions of Brazil, during rainy and dry season of the year. A 2³ factorial arrangement was used to analyse the experiment (two types of bread, pasture and season). Significant effects were obtained for type of pasture on total titratable acidity. The pH was influenced by season and type of pasture. The microbial activity, mensured through methylene blue reduction time, was more intensive on rainy season and rangelands than dry season and grasslands, respectively. In the interpretation of the results of these tests for goats, should be considered mainly the season and type of pasture, without despising the breed.
