“…Start-and stop-time of drinking was noted, along with the number of the pig and the nipple from which it was drinking. All other behaviours close to the nipple drinkers (in the range of the RFID antenna as determined in Maselyne et al, 2014a) were also noted. Observations were spread over 2 days (1 and 3 October 2013 -test-day 1 and 2), resulting in 6 h of observation for each nipple, or 24 h in total.…”

“…When only one tag was registered, it was likely that the pig was with only one ear in range of the antenna, and thus not drinking, but instead playing near the nipple, lying down in front of the nipple or passing by the nipple. However, it is possible that actual drinking visits contain registrations of only one tag of the pig when the orientation of the ear is such that the tag is not in range of the antenna (Maselyne et al, 2014a) or when an ear tag is lost. The minimum duration criterion mainly reduced the number of false RFID visits.…”

“…Registrations would be different whether one or two tags per pig would be available, since registrations are influenced by movement of the tag and tag orientation towards the antenna (Maselyne et al, 2014a). No great difference in the performance of the RFID system was observed when using one or two tags per pig in terms of the absolute values of the drinking variables (Table 1) or in the measurement performance (Table 2).…”

“…Each pig was fitted with two HF RFID tags (IN Tag 300 I-Code SLI; HID Global Corporation, Austin, TX, USA) at the time of introduction in the pen, one in each ear. For more information on the RFID tags, the RFID system and its measurement range, see Maselyne et al (2014a and2014b).…”

“…Most RFID systems used for animal identification are low frequency (LF) RFID (Junge et al, 2013;Andersen et al, 2014). However, RFID systems at higher frequencies (such as high frequency (HF) and ultra high frequency (UHF)) can read several tags simultaneously (Maselyne et al, 2014a), which provides more possibilities for identification of multiple animals in group housing systems. In a previous study, the potential of HF RFID was illustrated for measuring the feeding behaviour of multiple pigs at the feed trough (Maselyne et al, 2014b).…”

Changes in the drinking behaviour of pigs may indicate health, welfare or productivity problems. Automated monitoring and analysis of drinking behaviour could allow problems to be detected, thus improving farm productivity. A high frequency radio frequency identification (HF RFID) system was designed to register the drinking behaviour of individual pigs. HF RFID antennas were placed around four nipple drinkers and connected to a reader via a multiplexer. A total of 55 growing-finishing pigs were fitted with radio frequency identification (RFID) ear tags, one in each ear. RFID-based drinking visits were created from the RFID registrations using a bout criterion and a minimum and maximum duration criterion. The HF RFID system was successfully validated by comparing RFID-based visits with visual observations and flow meter measurements based on visit overlap. Sensitivity was at least 92%, specificity 93%, precision 90% and accuracy 93%. RFID-based drinking duration had a high correlation with observed drinking duration ( R 2 = 0.88) and water usage ( R 2 = 0.71). The number of registrations after applying the visit criteria had an even higher correlation with the same two variables ( R 2 = 0.90 and 0.75, respectively). There was also a correlation between number of RFID visits and number of observed visits ( R 2 = 0.84). The system provides good quality information about the drinking behaviour of individual pigs. As health or other problems affect the pigs' drinking behaviour, analysis of the RFID data could allow problems to be detected and signalled to the farmer. This information can help to improve the productivity and economics of the farm as well as the health and welfare of the pigs.

For sustainable pork production and maximum pig welfare, all health, welfare and productivity problems in the barn should be detected as early as possible. In this paper, an automated monitoring and warning system is proposed. Based on measurements of the feeding pattern, it is able to generate daily alerts for individual fattening pigs. Using historical data, the following types of warning systems were developed: (1) fixed limits that treat all pigs and all days equally; and (2) time-varying individual limits using the concept of Synergistic Control. These types of limits were constructed either for the number of registrations per pig or the average interval between feeding visits of a pig, leading to four warning systems in total. These warning systems were used to generate alerts during an online validation period. During an entire fattening period, all pigs were individually monitored to establish true alerts, false alerts and missed problems. The best performance was achieved for the Synergistic Control method on the number of registrations, with a sensitivity of 58.0 %, specificity of 98.7 %, accuracy of 96.7 % and precision of 71.1 %. Severe problems were detected on average within 1.3 days from the start of the problem. These are promising results that provide a solid basis for the development of a system for individual pigs but further improvements are warranted to make the system more practical.
