This work was carried out to evaluate the physical characteristics of the digesta throughout the gastrointestinal tract and to exam the conception of critical particle size that escape from the reticulum-rumen (RR), in the dairy bull calves fed diets with different concentrate levels. Thirty two dairy bull calves, one half straightbred Holstein and half crossbreed Holstein-Zebu, slaughtered with average six months of age and 190 kg LW, after fasting for 16 hours. The diets fed libitum were constituted of coast-cross […]
