近年来随着振兴上海,开发浦东和城市人民生活水平的提高,牛奶的需要量在不断增加。为此不断研究增加奶牛和提高产奶率,已成为畜牧生产和卫生部门“增产、灭蚊”的重要课题和当务之急。奶牛增多,蚊虫密度就会明显增加,这似乎是一对矛盾,但如何在奶牛场既保膘增加产奶率,又灭蚊防病,确系奶牛场新的要求和任务,并在此基础上再不断扩大经济效益和社会效益,建设祖国、造福人类。通过实验研究表明:上海市长江农场第一奶牛场,已取得灭蚊、保膘、增加产奶率一举三得的理想效果,兹将结果摘要简报如下:
In recent years, with the revitalization of Shanghai and the improvement of living standards in Pudong and urban areas, the demand for milk is constantly increasing. To continue to study increasing dairy cows and raising milk production rates has become an important issue and top priority of the livestock production and health departments for “increasing production and eliminating mosquitoes.” The increase in the number of cows will result in a marked increase in mosquito density. This seems to be a contradiction. However, how to increase the milk production rate in dairy farms and eliminate mosquito and prevent disease are indeed the new requirements and tasks of the dairy farms. We should continue to expand economic and social benefits, build the motherland and benefit the people. The experimental study shows that the first dairy farm in Shanghai Changjiang Farm has achieved the desired results of mosquito control and protection, and increased milk production rate. The summary of the results is as follows:
