Abstract

Determination of the pH and total titratable acidity from rumen liquor was carried out in Australian Merino and Corriedale sheep fed on pasture, in two seasons of the year (winter and summer), in Botucatu City, São Paulo, Brazil. Ruminal samples were collected using a standard tube, from 103 sheep during the winter period (50 Corriedale and 53 Australian Merino) and from 107 sheep in the summer (52 Corriedale and 55 Australian Merino). The results obtained for pH and total titratable acidity in Australian Merino sheep in winter and summer were, respectively 6,69 ± 0,20 and 6,75 ± 0,23, and 26,27 ± 5,02 and 29,24 ± 6.24 units. The results observed in these tests for Corriedale sheep in winter and summer were, respectively, 6,70 ± 0,21 and 6,84 ±0,28, and 27,26 ± 4,82 and 30,40 ± 5,11 units.
