Postgraduate volunteer service group of the School of Animal Science since 2012，In-depth visits to Chengyuan Shenglong Farm and Shahe Chunshan Dairy Farm in one session、Pinggu Shun Sunshine Dairy Farm、Fangshan Sanliyuan Animal Husbandry Co., Ltd.、Miyun Huazhan Dairy Farm and Kangyuan Dairy Farm、Fangshan District Zhongjia Yongan Technology Co., Ltd.、Jiuxian Cattle Farm, Changping District、Beijing Nankou Mancang Breeding and Breeding bet365 online sports bettingProfessional Cooperative and other major dairy breeding factories in Beijing，Learn more about the incidence of common diseases such as endometritis in dairy cows through on-site interviews with the relevant persons in charge of the farms and on-site inspections，Collect blood samples and bacterial flora, etc.，Distinguish the main pathogenic bacteria of endometritis in dairy cows in Beijing。Screen precision antibiotic drugs based on research and experimental results，Three new prescription drugs to be developed to treat chronic endometritis，Distributed to various cattle farms for free and conducted demonstration applications，Meanwhile，The "Dairy Cow Disease Prevention and Control Manual" was also given to the cattle farm for free to enhance the disease prevention and control capabilities of the cattle farm。
Collect blood samples from cows to help screen for infectious diseases in cattle farms
The animal science graduate student volunteer team received a report from the veterinarian at Shun Yangguang Farm in Pinggu District, Beijing，Cattle farms need to collect blood samples from all cows。The graduate student volunteer team is organized by the instructors Ni Hemin and Wang Xiangguo，Quickly organize people to go to Pinggu Shun Yangguang Farm，With the assistance of cattle farm workers，Successfully collected blood samples from 270 cows，The sample was centrifuged and the upper serum was extracted and sent to the monitoring station for inspection。After this blood collection，On the one hand, the graduate student volunteer team strengthened their understanding of blood collection technology and teamwork skills，On the other hand, it can respond as quickly as possible after receiving the report，Demonstrates the high mobility of the volunteer team。This emergency situation has enabled the volunteer team to achieve greater improvement in practice，It also greatly bet365 online sports bettingenhances the team’s collaboration capabilities。
They are “emergency doctors” who deliver babies to cows with dystocia
After receiving requests from the graduate student volunteer service team for difficult conditions such as dystocia and unexplained cases of cows lying on the ground in cattle farms around Beijing，Run quickly to the dairy farm，Discovered after inspection，Uterine torsion in cows。The condition was relieved by rolling，Pull out the calf using post-uterine exploration，Continuously tap the calf’s chest to restore breathing，Finally, mother and child are safe。
After this work to solve the problem of dystocia in dairy cows，The graduate student volunteer team has a better understanding of dystocia in dairy cows。Adopted timely and correct measures for emergency situations，Successfully resolved the condition。This emergency situation has enabled the graduate student volunteer team to achieve greater improvement in practice，It also greatly improved the team’s collaboration ability and cohesion。
Actively carry out training on cattle feeding management and disease prevention and treatment
The graduate student volunteer team actively participates in various cattle feeding management and disease prevention training。With the development of beef cattle industry，All regions have introduced Angus beef cattle directly from abroad，The incidence of beef cattle diseases is generally high in large-scale Angus beef cattle farms、Problems such as complex disease types。The graduate student volunteer team mainly conducts training on the causes of disease in six aspects of feeding and management，Ordinary cattle farmers have a more comprehensive understanding of the modern Angus cattle farm management model and disease prevention and treatment。
Technology supports dairy cow breeding and demonstrates live egg collection technology
To fully tap the breeding potential of well-bred cattle，Mass production of high-quality embryos，Reduce the cost of producing high-quality embryos，Also capable of egg-nuclear transplantation、Provide necessary materials for bet365 online sports betting appfurther research such as gene introduction，The team also conducted live egg collection from Holstein cows。Collecting eggs from well-bred dairy cows through live egg collection，A total of 12 oocytes were obtained through demonstration，After fertilization and culture, 8 fertilized eggs developed well。
"Responsive to all requests、Answer all your questions、Go there if necessary、Whenever there is difficulty, always help” is the principle of the graduate team of the School of Animal Science，They did it。They are guided by the actual needs of the cattle farm、Carry out "nanny" service，Use veterinary expertise，Serving grassroots dairy farms，Truely “write the paper on the front line of breeding”。
