Effect of the daily duration of calf contact on the dam's ultradian and circadian activity rhythms Open
Cow-calf contact systems are attracting increasing interest among farmers and some are already being implemented into dairy farms. However, a comprehensive assessment of animal welfare in these systems is lacking. One reason for this is th…

Evaluating the Activity of Pigs with Radio-Frequency Identification and Virtual Walking Distances Open
Monitoring the activity of animals can help with assessing their health status. We monitored the walking activity of fattening pigs using a UHF-RFID system. Four hundred fattening pigs with UHF-RFID ear tags were recorded by RFID antennas …

A Novel Chart to Score Rumen Fill Following Simple Sequential Instructions Open
Knowledge about feed intake and adequate nutritional status of dairy cows is important to achieve high milk yield in grazing systems. A possible, but subjective, method to estimate changes in grazing intake could be rumen fill scoring. Thu…

Model selection for 24/7 pig position and posture detection by 2D camera imaging and deep learning Open
Continuous monitoring of pig posture is important for better understanding animal behavior. Previous studies focused on day recordings and did not investigate how deep learning models could be applied during longer periods including night …

Influence of Cooling and Heating Systems on Pen Fouling, Lying Behavior, and Performance of Rearing Piglets Open
The rearing of piglets is a demanding phase of pig production partly because of the changing temperature requirements of the piglets during rearing. Piglets need high temperatures in the resting area, especially at the beginning, while the…

Turning the gaze to maize: The effects of maize kernels in straw as enrichment on exploration in pigs Open
Tail biting is one of the biggest problems in pig production systems that causes animal welfare and economic problems. Therefore, tail docking is a widely used intervention to reduce tail biting. However, appropriate enrichment material th…

Case Study on Recording Pigs’ Daily Activity Patterns with a UHF-RFID System Open
The main objective of this paper is the monitoring of daily activity patterns of fattening pigs at different locations in the housing environment using UHF-RFID. Four hundred fattening pigs were equipped with UHF-RFID ear tags and monitore…
View article: Influence of A Cooled, Solid Lying Area on the Pen Fouling and Lying Behavior of Fattening Pigs
Influence of A Cooled, Solid Lying Area on the Pen Fouling and Lying Behavior of Fattening Pigs Open
Increasing demands on animal welfare and the higher temperatures in summer due to climate change make it necessary to adapt conventional pig husbandry systems. A cooled, solid lying area has the potential to increase lying comfort and redu…

Automatically detecting pig position and posture by 2D camera imaging and deep learning Open
Prior livestock research provides evidence for the importance of accurate detection of pig positions and postures for better understanding animal welfare. Position and posture detection can be accomplished by machine vision systems. Howeve…
View article: Influence of Increased Light Intensity on the Acceptance of a Solid Lying Area and a Slatted Elimination Area in Fattening Pigs
Influence of Increased Light Intensity on the Acceptance of a Solid Lying Area and a Slatted Elimination Area in Fattening Pigs Open
Animal welfare labels have been introduced to improve housing conditions in conventional pig systems. Animal welfare should be increased by, e.g. offering a well-accepted and comfortable solid lying area. This study investigates the effect…

Monitoring trough visits of growing-finishing pigs with UHF-RFID Open
Automatic monitoring of animal feeding behaviour in commercial farms is desirable as it is an important indicator for the well-being and health of animals. Low-frequency and high-frequency radio frequency identification (RFID) systems have…
View article: Novel approach to determine the influence of pig and cattle ears on the performance of passive UHF-RFID ear tags
Novel approach to determine the influence of pig and cattle ears on the performance of passive UHF-RFID ear tags Open
The potential of passive ultra-high frequency radio frequency identification (UHF-RFID) as an electronic identification technology for precision livestock farming applications has been evaluated in different projects. Despite very promisin…

Comparison of different ultra-high-frequency transponder ear tags for simultaneous detection of cattle and pigs Open
Electronic animal identification is an important technology in modern animal husbandry providing great benefits. Low-frequency applications are state-of-the-art within the radio frequency identification of animals. Quasi-simultaneous detec…

Methodology of a dynamic test bench to test ultra-high-frequency transponder ear tags in motion Open
The electronic identification of sheep and goats has been obligatory in the European Union since 2010 by means of low-frequency radio-frequency identification systems. The identification of pigs and cattle is currently based on a visual ea…
