Although the dairy production industry in China is developing very rapidly, many problems still exist. At present, the development of the dairy cattle breeding from extensive scattered breeding to standardized and large-scale breeding is realized to a certain extent in China, but the fine and scientific management in the breeding process is still at a lower level. The monitoring and identifying means for the key physiological indexes of the dairy cows are limited, and the economic benefit and market competitiveness of the dairy industry in China are restricted to a certain extent. The realization of the modernization and the intellectualization of the dairy cow breeding production is an important guarantee for further promoting the upgrading of the animal husbandry industry in China and the international competitiveness of the dairy industry in China. In dairy cow breeding, bovine rumenic acidosis is a common disease affecting the health of dairy cows, and particularly, rumen acidosis in a subclinical state is difficult to find in an early stage. In severe cases, the cow may die.
Detecting changes of environmental factors such as pH value and temperature value of rumen of cow is an important measure for preventing rumen acidosis. However, the traditional cow rumen pH monitoring method has the following disadvantages: (1) the rumen content of the dairy cow needs to be taken out and then detected; (2) the rumen content of the dairy cow is easily polluted in the process of taking out the rumen content, so that the measurement result is inaccurate; (3) the operation process is complex, time and labor are consumed, and the requirement of real-time monitoring cannot be met.
