    Abstract: Wild plants play a pivotal role in people’s daily lives, providing numerous necessities such as food, medicine, and living tools for survival. Zada County, located in the southwestern part of Ngari Prefecture (མངའ་རི, mngav-ri) , Xizang Autonomous Region of China, bordering India, serves as an important gateway for China’s access to South Asia. This region used to engage in prosperous and lively border trade. Characterized by a plateau sub-frigid arid climate, characterized by low annual average temperature, low oxygen concentration, cold winters, and cool summers. The Zang People here has amassed rich traditional knowledge on the utilization of wild plants in adapting to harsh environments. To comprehensively and systematically investigate, document, and study the traditional knowledge of the Zang People in Zada County on the utilization of wild plants, an ethnobotanical investigation methods were adopted. The research involved interviews with 173 informants, recording 3 639 utilization reports (URs), and conducting quantitative analyses using UV, CV, and CII metrics. The results were as follows: (1) The Zang People in Zada County possesses extensive traditional knowledge on the utilization of wild plants, employing 119 species belonging to 40 families and 83 genera. (2) The utilization categories of wild plants in this area are diverse, with 8 utilization categories, and multiple plants possessing two or more uses simultaneously. (3) The most significant plants in people’s lives are Carum carvi (UV=1.220), Artemisia stracheyi (UV=0.919), Rheum acuminatum (UV=0.890), Cupressus sp. (UV=0.769), and Urtica dioica (UV=0.757). Theses plants are intimately connected to the lives of the local Zang People and are deeply loved by them. (4) The intricate and diverse plateau environment significantly influences the utilization of wild plants in this region. This research not only comprehensively and systematically documents the utilization knowledge and characteristics of wild plants in Zada County, but also provides evidence for the further exploration and rational utilization of local plant resources, contributing to the sustainable development of the region. At the same time, it also helps to promote the inheritance and promotion of traditional knowledge, contributing to the prosperity of local culture. In addition, this research has positive implications for biodiversity conservation, helping to raise public awareness and protection consciousness towards biodiversity, and promoting the balance and harmonious development of the ecosystem.

    Abstract:本试验旨在研究丁酸梭菌对肉鸡腿肌脂肪代谢的影响。试验选用1日龄爱拔益加肉公鸡192只,随机分为2个组,每个组6个重复,每个重复16只鸡。对照组饲喂基础饲粮,试验组饲喂在基础饲粮中添加1×109 CFU/kg丁酸梭菌的饲粮,试验期为42 d。结果表明,与对照组相比:1)饲粮中添加丁酸梭菌显著增加了21日龄肉鸡腿肌肌内脂肪含量(P0.05)。2)饲粮中添加丁酸梭菌显著降低了21日龄肉鸡腿肌激素敏感脂肪酶活性(P<0.05),显著提高了21日龄肉鸡腿肌脂蛋白脂酶活性(P<0.05),且有增加42日龄肉鸡腿肌脂蛋白脂酶活性的趋势(0.05展开 -->

  • 八角和杜仲叶提取物对断奶仔猪生长性能、血清酶活性及肝脏肿瘤坏死因子-α分布和表达的影响

    Abstract:本试验旨在研究饲粮中添加八角和杜仲叶提取物对断奶仔猪生长性能、血清酶活性及肝脏肿瘤坏死因子-α(TNF-α)分布和表达的影响。采用单因子试验设计,选择健康的“杜×长×大”断奶仔猪48头,随机分为4个组,每组3个重复,每个重复4头猪。对照组饲喂基础饲粮,试验组在基础饲粮的基础上分别添加八角提取物(500 mg/kg)、杜仲叶提取物(250 mg/kg)和金霉素(50 mg/kg)。预试期7 d,正试期42 d。结果表明:与对照组相比,饲粮中添加八角提取物、杜仲叶提取物和金霉素显著提高了断奶仔猪平均日增重(P<0.05),饲粮中添加八角和杜仲叶提取物显著降低了血清谷丙转氨酶、碱性磷酸酶活性和肝脏TNF-α mRNA相对表达量(P<0.05)。TNF-α免疫阳性结果主要见于肝脏的肝小叶间及肝血窦。由此可见,在饲粮中添加八角、杜仲叶提取物可提高断奶仔猪生长性能,并具有抵抗肝脏炎症反应及氧化应激的能力。

  • 八角及其精油和残渣对肉仔鸡生长性能、肠道发育和养分消化率的影响

    Abstract:本试验旨在研究八角、精油及残渣对肉鸡生长性能、肠道发育和养分消化率的影响。采用单因素完全随机试验设计,将1日龄爱拔益加肉仔鸡384只,随机分为4组,每组12个重复,每个重复8只。对照组肉仔鸡饲喂玉米-豆粕型基础饲粮,试验组肉仔鸡分别饲喂在基础饲粮的基础上添加5 000 mg/kg八角粉(八角组)、200 mg/kg八角精油(精油组)和5 000 mg/kg八角残渣(残渣组)的饲粮。八角组和精油组饲粮中反式茴香脑含量为0.204 g/kg,对照组和残渣组饲粮中反式茴香脑含量低于0.005 g/kg。试验期21 d。结果表明:1)八角组和精油组肉仔鸡平均日增重和平均日采食量显著高于对照组(P0.05)。与对照组和残渣组相比,饲粮中添加八角和八角精油显著提高了肉仔鸡21日龄体重(P<0.05)。2)与对照组和残渣组相比,八角组和精油组肉仔鸡空肠的相对长度显著提高(P<0.05),同时精油组小肠的相对重量显著提高(P<0.05);此外,八角组和精油组肉仔鸡空肠的相对重量显著高于对照组(P<0.05)。3)与对照组和残渣组相比,饲粮中添加八角和八角精油显著提高了十二指肠和空肠的绒毛高度(P<0.05)。4)精油组粗蛋白质的表观和真实消化率及表观和真实代谢能均显著高于其余各组(P<0.05)。由此可见,饲粮中添加5 g/kg八角或0.2 g/kg八角精油均可改善肉仔鸡生长性能、肠道发育,并提高肉仔鸡对养分的消化利用,而添加5 g/kg八角残渣没有此作用效果。
