The objective of this work was to evaluate the effects of different chemical forms of nitrogenous compounds (protein and non-protein) and carbohydrates (starch and soluble fiber) on intake, digestibility, and ruminal synthesis of microbial protein in cattle supplemented during rainy season. It was used five crossbred Holstein × Zebu steers, with average initial body weight of 211 ± 35 kg and fistulated in the rumen and abomasum. The treatments were: control (only pasture), and supplements based on corn + soybean […]
