During the first 10 weeks of age, goats (N = 36) received a daily and oral inoculation with autoclaved rumen fluid (AUT), rumen fluid from adult animals fed forage (RFF), or fed concentrate diets (RFC) or without inoculation (CTL). Means within a raw with different superscript differ (p < 0.05). Only families (f) with an average abundance higher than 0.01% and p-values <0.1 are shown.
