Sequencing of calf diarrhea virus macrogenes
With the rapid development of animal husbandry, the scale of the global cattle industry is also gradually expanding, the incidence of various types of calf disease is on the rise, resulting in a large number of calf deaths, affecting the growth and development of healed calves and breeding cattle replacement, not only restricting the healthy development of cattle industry, but also a serious threat to public health and safety.Its calf diarrhea is one of the important diseases affecting the healthy growth of calves, accounting for about 80% of the incidence of newborn calves.The causes of calf diarrhea are very complex, mainly including the feeding environment, bacteria, viruses and parasites, etc. By analyzing the number of clinical cases, it can be seen that, compared with poor feeding management caused by calf diarrhea, pathogens caused by infectious calf diarrhea cases accounted for more than 70% of the cases.We collected samples of calf diarrhea from different regions and randomly mixed them to detect viral pathogens of calf diarrhea using viral macro gene sequencing.
