花草茶渣（HTR）是一种可重复利用的资源，具有较高的营养价值和生物活性物质含量，可用作饲料添加剂。在本研究中，HTR 通过乳酸菌发酵，然后饲喂总共 90 头荷斯坦小母牛，分为 CN、LC 和 HC 组。补充剂改善了呼吸频率和直肠温度的生理指标，增加了免疫球蛋白和抗氧化能力相关参数的浓度，并降低了热应激相关参数和血清激素的浓度。小母牛的身高显着增加，而发酵的 HTR 则刺激了它们的能量代谢率。我们还研究了每组8头荷斯坦小母牛的粪便微生物群落组成，并与测试参数进行相关分析。我们发现该细菌与小母牛的能量利用率、生长性能、血清生化指标和粪便 SCFA 水平等特征密切相关。根据我们的研究结果，5% 发酵 HTR 替代玉米青贮饲料可能有利于小母牛在热应激下的特性。
Herbal tea residue (HTR) is a reusable resource with high nutritional value and bioactive substances content, which can be used as a feed additive. In the present study, HTRs were fermented by lactic acid bacteria, and then fed to a total of 90 Holstein heifers, termed as CN, LC, and HC groups. The supplementation improved physiological indices of respiratory frequency and rectal temperature, increased the concentrations of immunoglobulins and antioxidant capacity-related parameters, and reduced the concentrations of heat stress-related parameters and serum hormones. The heifers’ body height increased considerably, while their energy metabolism rates were stimulated in response to fermented HTRs. We also studied the fecal microbial community composition of 8 Holstein heifers in each group, and employed correlation analysis with tested parameters. We found that the bacteria were closely related to characteristics including the energy utilization rate, growth performance, serum biochemical indexes, and fecal SCFA levels of the heifers. Based on our findings, the 5% fermented HTRs replaced corn silage might be advantageous for the heifers’ characteristics under heat stress.
