It was evaluated in this study the effect of the type of the diet on duodenal flow of long-chain fatty acids in steers. The tested diets were the following: conventional (feedlot diet composed of 60% corn silage and 40% of concentrate); winter forage silage – rye grass (Lolium multiflorum, Lam); or tropical forage silage – association of millet (Pennisetum americanum, Leeke + alexander grass, Brachiaria plantaginea). Six Charolais × Nellore crossbred steers with cannulas in duodenum were used in a […]

It was aimed to compare the internal markers, indigestible neutral detergent (NDFi) and acid fiber (ADFi), and ADFi with oxide chromic to esteem the dry matter fecal production and nutrients digestibility of diets of bovine, in two outlines of collections (2 or 6 days). For the comparison among internal markers, 32 Nelore growing bulls, with 240 kg, were maintained under feedlot, receiving diets with different concentrate levels (20, 40, 60 and 80%). For the comparison among internal and external marker, […]
