In recent years，The yield of dairy cows in Beijing has increased steadily，But subject to resource environment、Policy、Affected by high costs and other factors，The number of dairy farms continues to decrease。Beijing has basically formed the Beijing area and Shunyi has been formed、Tongzhou、The dairy industry belt in southern Beijing, dominated by Daxing and Fangshan and other districts (counties) and Yanqing、The dairy industry belt in northern Beijing, dominated by districts (counties) such as Miyun and Huairou，Ensuring the quality, safety and stable supply of milk in Beijing。The destination of this event is Beijing Dingsheng Yujiu Animal Husbandry Co., Ltd. (one event)，The field was built in 2004，An area of about 230 acres，800 acres of which are used for waste disposal and planting，About 2,000 heads in stock，Daily milk production is about 26 tons。Since 2005，Persist in doing DHI testing every month，But cannot effectively utilize DHI data，Currently there is low milk production in the pasture、The problem of high incidence of mastitis。

Introduced，Students learned，1946 cows came to the ranch，938 lactating cows，In order to meet environmental protection requirements，The pasture transferred 800 acres of land for manure disposal and planting feed crops。“The report of the 19th CPC National Congress proposed the implementation of the rural revitalization strategy，Our school actively responded to the call，So on the one hand, our practice this time is to visit and learn，Let students be exposed to production practice；On the other hand, I also hope that through field inspections and visits to the ranch，Combining our expertise，Provide some rational suggestions for the ranch”。Professor Guo from the rural revitalization team of Beijing Agricultural College stated the purpose of the trip。
Field inspection and on-site communication
Subsequently，All members of the practice group put on protective clothing，Enter the ranch。Visited the dairy barns in turn bet365 online gamesunder the leadership of farm director Wang、Feed workshop、Manure treatment workshop、Milking sheds and other locations。
Walking on the road inside the venue，Basically no mosquitoes or flies can be seen，Can’t smell shit。Director Wang introduced: “The cattle farm uses dry and wet separation technology to process manure，The separated solid can be used as livestock bed after fermentation、Sports Ground Mat，Eco-friendly and comfortable，The liquid part can be used as fertilizer for surrounding farmland，Fully realized the utilization of manure resources”。The dairy farm has a good relationship with local villagers，On the one hand, it has solved some farmers’ employment problems，On the other hand, it provides organic fertilizer to farmers，Basically achieved mutual benefit,Made certain contributions to rural revitalization。Currently according to Beijing city policy，The cow playground has also been adjusted，Reduced environmental pollution and carbon dioxide emissions。
While learning about the advantages of ranching，The practice group also discovered some shortcomings，Some old-fashioned management methods are still adopted in the pasture，Unreasonable grouping of cattle，There is no reasonable grouping according to the three milk production levels of low, medium and high，Can cause low-yielding cattle to become overweight、Waste of feed increases cost。And the genetic basis of dairy cows is very different，Individual inconsistent，Will cause management difficulties。
By getting up close and personal with the various joints of the ranch，The practice group gained an in-depth understanding of the advantages and disadvantages of the ranch，Especially the methods of dry and wet separation of manure and fermentation of solid manure made everyone feel deeply，Benefited a lot。
Scientific analysis and expansion ideas
In response to the feedback received from the ranch before the start of this event，The practice group provided targeted feedback to the ranch on the problems found on site。Through multiple communications between members of the practice group and the ranch data clerk，Get the cattle information of this ranch、DHI detection data、Cow breeding events and other information，By collection、Analyze bet365 online sports betting appDHI data to help the ranch solve its own problems，Improve the economic benefits of pasture。Based on the current status of pasture feed ingredients and rations，Proposed a reasonable diet formula，Recommended precise feeding for different groups of cows。Use the dairy farm intelligent management system developed by our team，Analyze the production performance of dairy cows on this ranch，Generate analysis report。Shared analysis results with ranch technicians，Point out the shortcomings of pasture，Based on the ranch’s own conditions，Provide opinions for the development of the ranch。In addition, by establishing a mastitis prediction model，Early warning of cows with high risk of mastitis in dairy cows，Discover early、Prevent and treat as early as possible，Improving milk quality and safety。
