Leizhou goats are famous for their delicious meat but have inferior growth performance. There is little information on rumen-protected fat (RPF) from the Leizhou goat. Hence, we observed the effects of RPF on growth, fecal short-chain fatty acids, and bacteria community with respect to Leizhou goats. Twelve goats (13.34 ± 0.024 kg) were selected and assigned randomly to one of two treatments: (1) a control diet (CON) and (2) 2.4% RPF with a control diet (RPF). The final body weight and average daily gain (ADG) were greater (<i>p</i> < 0.05), and the dry matter intake (DMI): ADG was lower (<i>p</i> < 0.05) in the RPF group than in the CON group. There were no differences in DMI between the CON and RPF groups. The concentrations of total short-chain fatty acids, acetate, propionate, and butyrate were lower (<i>p</i> < 0.05) in the RPF group than in the CON group. The relative abundances of <i>Ruminococcus</i>, <i>Rikenellaceae_RC9_gut_group</i>, <i>Treponema</i>, <i>norank_f__norank_o__RF39</i>, <i>Eubacterium_siraeum_group</i>, and <i>Ruminococcus_torques_group</i> were lower (<i>p</i> < 0.05) in the RPF group than in the CON group. The relative abundances of <i>Bacteroides</i>, <i>norank_f__norank_o__Clostridia_UCG-014</i>, <i>norank_f__Eubacterium_coprostanoligenes_group</i>, <i>Eubacterium_ruminantium_group</i>, <i>norank_f__Oscillospirale-UCG-010</i>, <i>Oscillospiraceae_UCG-002</i>, and <i>Family_XIII_AD3011_group</i> were greater (<i>p</i> < 0.05) in the RPF group than in the CON group. It was concluded that RPF could improve the goats’ growth performance by regulating their fecal bacteria communities.
