The objective of this work was to evaluate the ruminal disappearance and nitrogen intestinal digestibility of 18 concentrate feedstuffs and four grasses, using an in vitro inhibitor with HCL-pepsin-pancreatin solutions and the three-step method. The disappearance of nitrogen compounds of feedstuffs was determined at 0 and 2 hours using 1.875 mg of N incubated on each three vessels. One of the vessels was submitted to intestinal digestion. On the second method, approximately 5 g of samples were incubated, during 16 […]
