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 ( < 0.05), and the dry matter intake (DMI): ADG was lower ( < 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 ( < 0.05) in the RPF group than in the CON group. The relative abundances of , , , , , and were lower ( < 0.05) in the RPF group than in the CON group. The relative abundances of , , , , , , and were greater ( < 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.
雷州山羊以其肉质鲜美而闻名，但生长性能较差。关于雷州山羊瘤胃保护性脂肪（RPF）的信息很少。因此，我们观察了RPF对雷州山羊生长、粪便短链脂肪酸和细菌群落的影响。选择12只山羊（体重13.34±0.024千克），随机分配到两种处理之一：（1）对照日粮（CON）和（2）添加2.4%RPF的对照日粮（RPF）。RPF组的终末体重和平均日增重（ADG）更高（P<0.05），干物质采食量（DMI）：ADG低于CON组（P<0.05）。CON组和RPF组之间的DMI没有差异。RPF组中总短链脂肪酸、乙酸、丙酸和丁酸的浓度低于CON组（P<0.05）。RPF组中[具体菌种1]、[具体菌种2]、[具体菌种3]、[具体菌种4]、[具体菌种5]和[具体菌种6]的相对丰度低于CON组（P<0.05）。RPF组中[具体菌种7]、[具体菌种8]、[具体菌种9]、[具体菌种10]、[具体菌种11]、[具体菌种12]和[具体菌种13]的相对丰度高于CON组（P<0.05）。得出的结论是，RPF可以通过调节山羊粪便细菌群落来提高其生长性能。
