# Progress of Machine Vision Technologies in Intelligent Dairy Farming
## 5 Conclusions
### The Advantages of Machine Vision in Precision and Large-Scale Breeding of Cows  
(1) Reduce farming costs  
With the expansion of dairy farming scale, the traditional artificial management mode requires a large amount of breeding and management personnel. More personnel investment means an increase in breeding costs. Although sensor technology can achieve the rapid detection of cow behavior and replace manual operations, it is still expensive for each cow to wear corresponding sensors, considering their cost and maintenance costs. The machine vision technology represented by image and video information processing requires only a few camera devices to be deployed at the farm, which is not only low-cost, but also simple to maintain, so it can save a lot of labor costs and maintenance costs for the large-scale breeding of dairy cows. At the same time, machine vision can use a single visual device to recognize multiple behaviors of cows, which can also save a lot of costs compared to sensor technology.  
(2) Improve breeding efficiency  
Traditional farming methods exhibit such phenomena as forage waste, artificial errors, and delays in diseases and production management. These factors can prevent breeding personnel from timely obtaining the status of dairy cows, causing a decline in farming efficiency and resource utilization. Through the daily behavior monitoring method of machine vision, an abnormal status of dairy cows during the breeding process can be detected as early as possible, and measures can be taken in a timely manner to avoid further losses. Precision farming based on machine vision will greatly improve the efficiency of dairy farming and be an important direction for the development of dairy farming in the future.  
Improve animal welfare  
The detection of cow health and diseases through artificial and sensor methods can cause stress reactions in cows. These methods are not conducive to the welfare of dairy farming. The contactless approach of machine vision has no impact on the daily activities of dairy cows, thereby improving their welfare. In addition, machine vision monitoring of the daily behavior of dairy cows can also provide reference data for the welfare-oriented breeding of dairy cows.  
Provide data support for precise breeding of cows  
Through machine vision technology, the identity, behavior, diseases, and other information of cows can be digitized. These data are the foundation for the construction of a digital information platform for dairy farming. The establishment of a digital platform can provide decision-making support for intelligent and precise dairy farming.  
From the research results described in this article, it can be seen that current machine vision has achieved outstanding research results in cow behavior recognition, disease diagnosis, and other aspects. Machine vision technology is gradually becoming one of the important auxiliary means for precision dairy farming. However, in the process of practical application and promotion of this technology, further research and mining are needed in the following aspects.
