...Viral Diarrhea Virus) in yaks in Hongyuan, Sichuan province, a cold climate and high altitude area of China. Totally, 516 yak serum samples were randomly got during 2012 to 2014. BVDV was found highly prevalent among the adult yaks (51.1%; 95% CI: 46.5-55.6) and calves (60.5%; 95% CI: 43.4-76.0), respectively. The prevalence of BVDV infection in 2012 to 2014 was 45.3% (95% CI: 38.6%-52.1%); 56.0% (95% CI: 49.7-62.2) and 60.5...

...ations. In addition, the yaks exhibit some diversity based on the number of unique haplotypes within each population; however, they have not heavily and significantly diverged because all the populations share the most high-frequency haplotypes. Therefore, this study not only shows that the different ecotype populations of the Naqu yak carry high genetic diversity but also indicates that frequent genetic material exchanges have led to smaller differences in ge...

...ntarget animals, such as yaks, Tibetan sheep, dogs, vultures, and birds, is also tested. Results show that the toxin is encoded by a type D botulinum neurotoxin gene. The DNA and amino acid sequences of the full neurotoxin gene comprise 3831 base pairs and 1276 amino acid residues, respectively. The nucleic acid and protein sequences of the toxin exhibits 99% homology with those of a known type D botulinum neurotoxin gene, and the composition of the functional...

...rbivores: Tibetan sheep, yaks, and horses, and three kinds of wild herbivores: Tibetan antelopes, Tibetan wild assess, and blue sheep.All the kinds of large herbivores in the aerial images are detected and located using deep learning model of the MASK R-convolutional neural network (CNN), and the average recall, correct, and leakage are 89%, 98.4%, and 10.8%, respectively. Furthermore, the contour vector of the herbivores is obtained by extracting the mask gen...

...i>) infection in Tibetan yaks was investigated using an ELISA assay. The results showed that the 305/849 (35.92%) studied animals were sero-positive for F. hepatica with the further distribution of 24.20% (38/157), 38.02% (92/242) and 38.89% (175/450) from Bayi, Mainling, and Gongbo’gyamda areas, respectively. The seroprevalence of F. hepatica increased from 20.75% to 48.8% with age of yaks, with the...

... respiratory distress in yaks, and it can further result in reproductive diseases and late-term abortions. In this article, we conducted a systematic meta-analysis aimed at exploring BHV-1 prevalence in yaks of the Chinese Qinghai-Tibetan Plateau (QTP). To complete this analysis, we identified all relevant articles on this topic in both English and Chinese literature databases published through March 20, 2020. Studies were n...

... study, 10 female Gannan yaks with an average body weight of 234.9±10.5 kg were selected for research purpose (natural grazing) in Gannan Pastoral Area of Gansu Province. The forage, rumen fluid and milk samples were collected during green-up time, flowering time and withering time of forage to determine nutrient composition of forage, fermentation parameters of rumen fluid, and CLA in milk fat. The correlation analysis was studied in order to find out ...

...or milk fat synthesis in yaks are still unclear. This study examined the regulatory mechanism of milk fat synthesis in yak mammary epithelial cells (YMECs) by investigating the role of Ribosomal protein L8 (RPL8) in the mTORC1-SREBP1 signaling pathways. The results showed that over-expression or inhibition of RPL8 had a significant effect on triglyceride (TG) secretion, which also affected the sterol regulatory element-binding protein 1 (SREBP1) pathway. Simil...
