The assessment of animal welfare on-farm is important to ensure that current standards are followed. manual proposed by Welfare Quality® (WQ), although being an essential tool, only a point-estimate in time, very time consuming perform, evaluates subset the animals, and performed subjective human. Automation through information technologies (ITs) could provide continuous objective real-time on all animals. aim systematic review was identify ITs developed for monitoring within pig production...
The aim of the experiment was to study impact high ambient temperature (25°C) around farrowing on crated sows unable perform thermoregulatory behavior. Twenty were housed in 2 rooms conventional crates. In 1 room (CONTROL) kept at 20°C. other (HEAT) initially 20°C and gradually raised until it reached 25°C from d 112 115 gestation. Then lowered Sows continuously video recorded for behavior recording. Sows' respiration rates 3 before 5 after farrowing. rectal temperatures 8 farrowing, sows'...
One challenge of intensive pig production is tail damage caused by biting, and farmers often decrease the prevalence through docking. However, docking not an optimal preventive measure against thus, it would be preferable to replace it. The aim current study was investigate relative effect three possible measures damage. included 112 pens with 1624 finisher pigs divided between four batches. Pens were randomly assigned one level each treatments: (1) tail-docked (n=60 pens) v. undocked (n=52...
Change in the frequency of contact between pigs within a group may be indicative change physiological or health status one more group, occurrence abnormal behaviour, e.g. tail-biting. Here, we developed novel framework that detects and quantifies interaction, i.e., pig head to another rear, groups. The method does not require individual tracking/identification uses only inexpensive camera-based data capturing infrastructure. We modified architecture well-established deep learning models...
Tail damage within the production of finisher pigs is an animal welfare problem. Recent research suggests that removal known risk factors may not be enough to eliminate tail biting, especially in undocked pigs, thus a different strategy worth investigating. This could early detection using behavioural changes observed before damage. If these stages biting can detected occurs, then prevented by interventions. The first step developing such identify types behaviour emerge during biting. Thus,...
We investigated whether hypothermia in newborn piglets could be reduced by applying different thermal aids. The experiment was performed on 150 from 24 sows. Right after birth, the were moved to a wire mesh cage for first 2 h of life where they experienced 1 7 combinations flooring (solid vs. slatted) and treatments: control, with no additional aids solid floor (n = 26) or slatted 26); built-in heating 31) as radiant plate (FloorPlate; n 19); heater above (RadiantC; 22) (RadiantSlat; 18);...
Tail biting in pigs is an animal welfare problem, and tail should be prevented from developing into damage. One strategy could to predict events of so that the farmer can make timely interventions specific pens. In current investigation, sensor data on water usage (water flow activation frequency) pen temperature (above solid slatted floor) were included development a prediction algorithm for biting. Steps modelling sources with dynamic linear models, optimisation training artificial neural...
Hypothermia, experienced by piglets, has been related to piglet deaths and high early use of a heated creep area is considered important prevent hypothermia. The aims the present study were investigate how newly invented radiant heat source, eHeat, would affect piglets' whether light in works as an attractant on piglets. A total 39 sows, divided between two batches, randomly distributed three source treatments: (1) standard infrared lamp (CONT, n=19), (2) eHeat with (EL, n=10) (3) without...
Engagement in play behaviour has been associated with the presence of positive affective states and, thus, proposed to be an indicator animal welfare. However, interpretation animals remains challenging due complexity motivating factors. Accordingly, we aimed clarify whether Yorkshire × Landrace weaner pigs would engage more well-nourished they were by examining effects weight gain, feeding behaviour, and drinking on two types [locomotor-rotational (LOC) social (SOC)]. In total, 24 litters...
Abstract High piglet mortality constitutes a welfare challenge in organic pig production. Litter characteristics were investigated from parities 1–5 of two hyper‐prolific hybrids with different selection traits an commercial herd (DanBred vs. Topigs Norsvin [TN70]). TN70 sows had more functional teats than DanBred sows, and their offspring higher birth weights. Several interactions between hybrid parity found. The total born increased was pronounced for sows. weight at weaning 1–4 compared...
Pen fouling, where the pigs choose to rest in their designated excretion area (the slatted floors) and excrete resting solid floors), is an undesired behaviour should be prevented when possible. One strategy prevent fouling early detection by means of either animal or environmental measures changing prior fouling. The aim present study was investigate whether lying pattern temperature pen changed last 5 days event this differed from pens without (controls). Fouling events recorded at level...
Heart rate (HR) is a vital bio-signal that relatively easy to monitor with contact sensors and related living organism’s state of health, stress well-being. The objective this study was develop an algorithm extract HR (in beats per minute) anesthetized resting pig from raw video data as first step towards continuous monitoring health welfare pigs. Data were obtained two experiments, wherein the pigs recorded whilst wearing electrocardiography (ECG) system gold standard (GS). In order...
Piglets being crushed by the sow is a major welfare challenge in outdoor pig production. To develop interventions with highest impact on mitigating crushing, it necessary to know whether behaviour leading up crushing can be considered mainly sow- or piglet-related due inappropriate housing conditions and thus genetics of factor importance. In this observational study, piglets classified as fatally based necropsy were identified video recordings. Seventy-two events observed 32 litters. Forty...
