Abstract
Many hog farmers are now suffering from high pig mortality rates due to various wasting diseases and increased breeding costs, etc. It is therefore necessary for hog farms to implement systematic and scientific pig production technology to increase productivity and produce high quality pork in order to solve these problems. In this study, we describe such a technology by suggesting a ubiquitous hog farm system which applies WSN (Wireless Sensor Network) technology to the pig industry. We suggest that a WSN and CCTV (Closed-circuit television) should be installed on hog farms to collect environmental and image information which shall then help producers not only in monitoring the hog farm via the Web from outside the farm, but also facilitate the control of hog farm facilities in remote locations. In addition, facilities can be automatically controlled based on breeding environment parameters which are already set up and a SMS notice service to notify of deviations shall provide users with convenience. Hog farmers may increase production and improve pork quality through this ubiquitous hog farm system and prepare a database with information collected from environmental factors and the hog farm control devices, which is expected to provide information needed to design and implement suitable control strategies for hog farm operation.
Highlights
The Korean pig industry has been forced to compete directly with those in developed countries due increased feed prices and FTA treaties, etc. [1], and further is suffering from high pig mortality rates caused by various wasting diseases and high production costs due to price increases for feed, other materials and energy [2]
The proposed ubiquitous hog farm system shall be classified to three stages following Figure 2, and each class is composed of the physical layer which consists of environmental sensors, RFID, CCTV and other control facilities of the hog farm, and the application layer which consists of interfaces that support monitoring of the hog farm and the controlling service of the pig breeding environment, and of the middle layer which supports the communication between the physical layer and the application layer, and stores the information collected from the hog farm in a database, provides monitoring and controlling services while maintaining the optimal status of the pig breeding environment
Alien 2850 BAP Dev Kit was used to monitor pigs’ histories and the RFID used in the proposed ubiquitous hog farm system and its specifications are shown in Figure 12 and Table 3
Summary
The Korean pig industry has been forced to compete directly with those in developed countries due increased feed prices and FTA treaties, etc. [1], and further is suffering from high pig mortality rates caused by various wasting diseases and high production costs due to price increases for feed, other materials and energy [2]. Pig breeding environment information and external environmental information are collected through a wireless sensor network formed with sensors installed in the hog farm, and visual information about the hog farm is collected and monitored through CCTV. Hog farm facilities could be automatically controlled based on some breeding environment value which is already set up and SMS notice service shall be provided to users when dangerous situation occur, while RFID technology enables users to collect each pig's identification and individual information for their efficient history management. It is necessary to analyze the environmental features of the hog farm and each individual animal’s behavioral characteristics in a specific environment in order to develop the ubiquitous hog farm system as proposed in the study. This chapter shall list some items which an ubiquitous hog farm system must have by examining relations between each environmental aspect and the individuals’ behavioral characteristics
