Complexity of behavioural sequences and their relation to stress conditions in chickens (Gallus gallus domesticus): a non-invasive technique to evaluate animal welfare
A complexity analysis was performed on the behaviour time series of four groups of seven chickens (Gallus gallus domesticus) using the detrended fluctuation analysis (DFA). DFA quantifies the fractal-like correlation properties of behaviour sequences on short time scales (seconds) over active periods of approximately 0.5 h (2050 s). In this study the level of randomization […]
Diurnal rhythms, locations and behavioural sequences associated with eliminative behaviours in fattening pigs
Understanding eliminative behaviours in pigs is very important to maintain individual and pen cleanliness. In this experiment, twenty fattening pigs were housed in four concrete floor pens with a floor space of 3.25 m2 per pig and free accessibility of outdoor runs. We studied the diurnal rhythms, locations and behavioural sequences associated with eliminative behaviours […]
