Dong's Sanyuan Qinghe Dairy Cattle Breeding Center is mainly engaged in dairy farming. 200 1 dong is the manager of the newly established sanyuanhe beijiao branch. In the process of dairy farming, Dong led the staff to widely popularize and apply the digital management system of dairy production represented by measurement to measure the production performance of dairy cows. All adult cows are tested for DNI virus every month. Digital management methods such as CMT measurement, cow body condition score, backup cow body size and weight evaluation system, SCC and TBC measurement, DHI report, etc. provide the basis for scientific decision-making. At the same time, a labor competition with the theme of "cultivating high-yield cows, producing high-quality milk and pursuing high efficiency" was launched, and the cattle farm affiliated to Beijiao Branch launched a labor competition of "improving calf survival rate", and the calf survival rate was 100 within one month. Sanniu Farm changed the disinfection of medicinal bath cups to spraying medicinal bath liquid with watering can before milking, which reduced the probability of cross infection, greatly reduced the incidence of subclinical mastitis and greatly improved the quality of milk. The price of milk increased from per kilogram 1.83 yuan to more than 2 yuan. In 2004, economic and technological innovation projects were carried out, and rationalization suggestions were made 15, and 9 projects were implemented, resulting in benefits of 1.2 million yuan, and 3 technical innovation projects were tackled, resulting in benefits of 60,000 yuan. Six items were added in two sections, and the efficiency was 6.5438+0.4 million yuan.

Sanniu Farm in the northern suburb was built in 1958, with outdated infrastructure, poor cowshed conditions and low production level. In order to change this backward situation, Beijiao Branch decided to transform it into the first dairy farm in Beijing that combines old and new technologies. Dong took the lead in formulating the reconstruction plan of Sanniu Farm, dismantled the water tower and technical room, and built a feeding passage between two rows of cowhouses, which enabled the advanced TMR feeding technology to be implemented smoothly. Five milking equipment imitating arbitrage valves were installed, which changed the milking conditions and greatly improved the milk quality. The incidence of breast diseases decreased from 33% before the reform to 5%. According to statistics, the daily output of three adult cows has exceeded 27 kg, the milk quality has been greatly improved, the per capita income of workers has increased steadily, and the enthusiasm of cadres and workers has been high.

In 2005, Dong directed the production technology department to carry out a series of training on standardization of dairy production technology in combination with the implementation of standardization. Combined with the popularization of new technology and new technology, the training of cow grouping, TMR ration matching technology and TMR machinery use and maintenance was carried out, which improved the theoretical level and professional skills of technicians and employees, increased the average number of cows to 265,438 0.7, and further improved the labor productivity; The production level has been greatly improved, and the daily milk production of adult dairy cows has exceeded 9 tons, a record high. The production level and comprehensive score of Beijiao Branch ranked first in the dairy cow system of the group company. Under the leadership of Dong, the economic benefits of the enterprise have been continuously improved, and the daily output of adult dairy cows has increased from 20.93 kg per year to 24.83 kg in 2005. The annual output increased from 7639 kg of 200/kloc-0 to 9062 kg in 2005, with an increase of 1423 kg, with an increase of 18.6%. The quality of milk has also been greatly improved: in 2005, the average number of somatic cells in milk was 390,000 /ml, and the number of microorganisms was1.20,000 /ml, which was the best level in Beijing dairy cow system; Labor productivity has been greatly improved; The average number of cattle raised increased from 12.7 and 5438+0 in 2006 to 210.7 in 2005; The per capita income of employees increased from 2001.1.000 yuan to 25,000 yuan in 2005, an increase of 2.3 times.

At the beginning of 2006, Sanyuan Lvhe carried out organizational reform, and three branches in northern suburb, western suburb and south exit merged to form a three-branch company, with Dong as the manager of the three-branch company.
