It resulted in an accurate feeding dry matter difference between the actual feeding diet and the calculated diet. These differences cause changes in the actual feeding ingredients of dairy cows, which affect rumen fermentation stability and nutrient available to cows. Leading to the fluctuations in milk production and milk composition. This project will be based on the need for precise TMR preparation on-site, and find a method to quickly assess the quality of raw materials on site as a basis for fine-tuning the formula. The application of online milk volume and milk component monitoring is commonly used to evaluate the production performance and milk quality changes. We will integrate the characteristics of its continuous data to monitor the stability of TMR ingredients and animal health, with automatic milking robot and milk quality real-time online. The two systems will be applied to obtain the milk production and milk composition data for each milking, to evaluate the effect of feeding accurate TMR and improve the value of monitoring information.乳牛飼糧線上監控乳品質dairy cattle dieton-line monitormilk quility
