Abstract

Four Nellore steers cannulated with average weight of 400 ± 12 kg were utilized in a Latin square design, to evaluate the effect of substitution levels of corn by citrus pulp on rumen fermentation. The treatments consisted of substitution levels: (0, 40, 60 and 80%, in the dry matter). The pH, volatile fatty acid and ciliate protozoa of the rumen content were evaluated. The addition of citrus pulp to the diets decreased the pH of rumen liquid (p < 0.01) linearly, the quadratic effect of the total volatile fatty acid, of prop ionic acid, butyric acid and the total ciliate protozoa number (p = 0.03; p =0.01; p = 0.02; e p < 0.01, respectively). There was linear increase of the acetate: propionate ratio (p = 0.07). The substitution of corn by citrus pulp improved rumen environment to 60% level
