This paper analyzes the effects of feed and feeding on milk production of dairy cows. It is demonstrated that feed affects the growth, development, reproduction, lactation and health of dairy cows. Based on our analysis results, some measures to avoid risks of milk production are proposed with respect to feed management, reasonable dairy formulation, scientific feeding and reasonable enhancement of lactation milk production.

Some environmental factors affect the milk yield, development and reproduction of dairy cows. In order to increase the economic benefits of milk production and reduce potential risks, it is necessary to find and avoid environmental risk factors. This paper analyzes the effects of drinking water temperature, humidity, light and noise on milk production. Controlling drinking water temperature, temperature of maternal milk for calves, cowshed temperature and humidity and other environmental sanitation conditions, regulating light illumination time and avoiding noise are helpful to increase milk yield, disease resistance, feed utilization rate, reproductive performance. In conclusion, regulation of environmental conditions can reduce risks in milk production, increase the milk production performance of cows, and enhance the economic benefits of milk farmers.

Integration of dairy industry plays an important role in promoting its development and modernization. At present, the poor foundation and low level of dairy industry are severely hindering its rapid and healthy development. This paper highlights the necessity of dairy industry integration across central China. Moreover, we put forward suggestions on improving dairy industry integration by constant modifications of the production mode, strengthened regulation and oversight of the industry, improved scientific dairy farming, intensified understanding of dairy industry integration, establishment of dairy farmers’ organizations and formation of a contractual mode for raw milk purchase.

Nowadays, the dairy industry has gradually developed into large-scale production from the traditional mode. With expanding farming scale, construction of dairy farms in high temperature and high humidity areas is becoming increasingly important. The infrastructure conditions directly affect the milk quality and economical benefit of breeding and reproduction of cows. This paper analyzes the design of dairy farms based on site selection, building construction, ventilation, cooling and epidemic prevention, aiming to alleviate, to some extent, the negative impact on cow breeding of high temperature and high humidity so as to improve the breeding benefit.
