Dairy calf performance is important for productivity later in life. Prebiotics have been
shown to improve performance measures such as average daily gain, feed intake, and
digestibility. Volatile fatty acid production may increase nutrient digestibility and subsequently
increase feed efficiency. In a study conducted with calves fed mannan oligosaccharides, no
differences in volatile fatty acid production were observed (Hill et al., 2009) and no differences
were seen in dogs supplemented with fructooligosaccharides or
