The objective of this paper was evaluate ammonia concentration, pH of ruminal liquid and microbial synthesis efficiency in diets with different energetic sources: corn (CO), corn/cassava hulls (CC), cassava root (CR) and cassava by-product flour (CB). Four Holstein steers (270 kg) were used, in a 4 X 4 Latin Square design. The marker utilized for determination of duodenal and fecal flow was the acid insoluble ash. There was not effect in the ruminal pH of the experimental diets, however smaller […]

The starch solubility in bicarbonate-phosphate buffer (SSB) and the ruminal degradability of starch from some feed by the in situ technique, using three Holstein cows, were evaluated in this study. The feeds were ground through a 2-mm screen for the concentrate and a 5-mm screen for forage and incubated using nylon bag (53mm). The starch concentration in corn, sorghum, cassava scraping, wheat bran, triticale, corn silage, sorghum silage, soybean meal, cottonseed meal and citrus pulp were: 79.3, 83.4, 91.4, 49.1, […]
