Abstract
In this study we have developed an automatic monitoring system based on wireless communication networks in both dairy and pig farms to replace traditional manual data collection of the environmental conditions and manual controls of fans and water control valves in livestock farms to solve the man-power shortage problem for livestock farming. Firstly, sensors for detecting temperature, humidity, illumination, wind speed and the control circuit and communication system were installed. The monitoring programs were subsequently designed to transmit the data back to the user interface display of the office through RFU-400 wireless communication modules, and the data collected from the farm environment have been stored in a database for data analysis. Finally, the fans and water spray valves have been automatically activated duly to improve the temperature and humidity of the livestock farms. We analyzed the data collected from the sensors with regard to the lactation yields for dairy cows, and suggested optimized environmental parameters for dairy cows to increase their appetite and lactation yield, or increase the feed conversion rate of the pigs. We expect the process and results of this study can result in helpful reference to livestock farming, and help to achieve the best economic benefits in raising cattle, pigs and so forth.
Highlights
Nowadays since the birth rate of Taiwan keeps on declining and the population aging rate keeps on increasing, the labor force is gradually shrinking
In August, the hot and humid season, the values of temperature-humidity index (THI) would mostly fall within the range of moderate heat stress, and it was showed in Figure 11 that the average lactation yield per dairy cow was 20.8167 L/day, which was significantly 4.0935 L/day lower compared to the average lactation yield per dairy cow in March
) and the temperature-humidity and the apparent temperature is the final value of THI, is the initial value of THI, is a given value of the initial lactation yield per dairy cow, is the final value of apparent temperature index (AT), is the initial value of AT, mm is the slope of line of the initial lactation yield per dairy cow, m THI is the slope of THI line, m AT is the slope of AT line
Summary
Nowadays since the birth rate of Taiwan keeps on declining and the population aging rate keeps on increasing, the labor force is gradually shrinking . The development of wireless communication technology contributes to the applications in a range of fields such as everyday life, agriculture [2,3,4], livestock farming, traditional industries, vehicle [5], transportation [6], medical care [7], and military defense It makes hard things easy and reduce time consumption. With the growth and development of industrial automation and wireless communication technology, applications of the automatic monitoring and control on the livestock farming and agriculture have become much more comprehensive and versatile. This study has applied radio frequency (RF) technology for remote wireless data transmission and remote control for monitoring the environment parameters of livestock farms.
