چکیده انگلیسی
Transporting sheep by sea exposes them to some prolonged floor motions, and their responses may depend on their space allowance. We simulated sea motion in a crate with a moveable and programmable floor, to measure behaviour and physiological responses. Nine sheep were exposed in groups of 3 for 1âh periods to Regular motion (8° roll of the floor every 15âs), Irregular motion (30 randomly selected amplitudes and duration of floor roll, with the same means as Regular), and No floor motion, at High (0.35m2/head), Medium (0.30âm2/head), and Low (0.26âm2/head) space allowances, with Low representing the Australian shipping standard. Lying time (Pâ<â0.001) and heart rate (Pâ=â0.05) were reduced during regular motion, but aggression increased during irregular motion (Pâ<â0.001), particularly at the end of the treatment. Both regular and irregular motion decreased rumination (Pâ=â0.003) compared with control. Pushing (Pâ=â0.03) and stepping (Pâ<â0.001) were more frequent in the Low than Medium or High space allowance treatments, but only when the sheep experienced Regular motion, and particularly at the start of treatment (Pâ=â0.03, Pâ<â0.001) respectively. Low space allowance decreased lying time (Pâ=â0.001) and variability in cardiac interbeat intervals (Pâ<â0.001), increased aggression (Pâ=â0.005) and the time sheep had their head facing downwards resting on the bars of the cage (Pâ=â0.02), indicating stress. Therefore, both regular and irregular ship-like motion at a low space allowance led to responses that suggested stress; giving more space than the current Australian standards may increase the welfare of sheep transported by sea.
