* Ctrl, control calves receiving autoclaved rumen fluid; Inoc, calves receiving fresh rumen fluid. standard error of mean. calculated using F-test. ♣ Treatment effect: inoculated with autoclaved rumen fluid (Ctrl) or fresh rumen fluid (Inoc). calculated based on the two groups of Inoc calves (Inoc-A and Inoc-B). † Each group of calves received rumen fluid from only one of four donor cows throughout the experiment. Only the sequence data of the donors for the included calves were presented.
