Drugs have been widely adopted in animal production. However, drug residues and bacterial resistance are a worldwide issue, and thus the most important organizations (FAO, USDA, EU, and EFSA) have limited or banned the use of some drugs and the use of antibiotics as growth promoters. Natural products such as medicinal herbs are unlikely to cause bacterial resistance and have no chemical residues. With these advantages, medicinal herbs have long been used to treat animal diseases and improve animal performance. In recent years, there has been an increasing interest in the study of medicinal herbs. S. baicalensis is a herb with a high medicinal value. The main active compounds are baicalin and baicalein. They may act as antipyretic, analgesic, anti-inflammatory, antiallergenic, antimicrobial, and antitumor agents. They also possess characteristics of being safe, purely natural, and not prone to drug resistance. S. baicalensis and its extracts can effectively promote the production performance of livestock and treat many animal diseases, such as mastitis. In this review, we summarize the active compounds, biological functions, and applications of S. baicalensis in the production of livestock and provide a guideline for the application of natural medicines in the production and treatment of diseases.

This study presents a systematic review and meta-analysis of studies on tick-borne encephalitis virus (TBEV) prevalence in ticks and human hosts in China, published between 2000 and 2023. Extensive searches were conducted on four databases—PubMed, CNKI, VIP, and Wan Fang. The findings indicated overall pooled prevalence estimates of TBEV infection in ticks and humans of 5.8% and 9.0%, respectively. The prevalence of TBEV in ticks was 4.8% (95%CI, 4.5–7.1%) during 2000–2010 and increased to 6.3% (95%CI, 4.7–7.8%) during 2011–2023, and was mainly distributed in Jilin (13.4%; 95%CI, 8.3–18.4%) and Inner Mongolia (4.5%; 95%CI, 1.8–7.1%). The prevalence of TBEV was higher in Dermacentor silvarum than in other tick species (8.1%; 95%CI, 3.2–12.9%). The seroprevalence of TBEV in humans increased from 4.7% (95%CI, 2.9–6.4%) during 2000–2010 to 17.6% (95%CI, 11.3–23.8%) during 2011–2023. Simultaneously, the analysis results of the population characteristics showed that females, forestry workers, military personnel, and farmers were found to be susceptible, and the highest seroprevalence was noted among homemakers and unemployed individuals. There were certain differences in the seroprevalence among populations in different provinces, especially in Xinjiang and Heilongjiang. This study can provide a reference for a more comprehensive and in-depth investigation of ticks and humans infected with TBEV in China.
