The objective of this trial was to investigate the intestinal digestion of neutral detergent fiber (NDF) using different markers and the effect of sampling collection period (daytime vs. diurnal) on nutrient digestion. Four crossbred Holstein x Zebu heifers fitted with ruminal and ileal cannulas were used in this trial. Animals were housed in individual pens and fed ad libitum bermudagrass hay plus 1 kg of concentrate (27% CP). The experiment lasted 60 days with seven days for diet adaptation and […]
