Sound avoidance by domestic pigs depends upon characteristics of the signal
Contributor(s):: Talling, J. C., Waran, N. K., Wathes, C. M., Lines, J. A.
Two groups of 12 pigs, weighing 25 kg, were individually exposed to a test sound in a modified unsignalled one-way avoidance procedure. The test sound for the first group was a recording from an animal transporter played at 84 dB(Lin), with a rise time of 2 s (uniform). For the second group,...

Relationship between number of conditioning trials per training session and avoidance learning in horses
Contributor(s):: McCall, C. A., Salters, M. A., Simpson, S. M.
Sixteen horses were used to determine if number of trials per training session (5, 10, 15 or 20) affected learning performance in an avoidance conditioning task. The horse had to move from one side of a test pen to the other during auditory cue presentation to avoid aversive stimulation (electric...

Do herbivores associate flavours with specific consequences in flavour aversion learning?
Contributor(s):: Kimball, B. A., Billings, V.
Goats were first offered a novel, maple-flavoured diet paired with either lithium chloride (LiCl) or oxalic acid (OA) delivered intraruminally. Aversion to maple diet persisted for 6 days, regardless of toxin. Following a 10-day intermission, aversion to maple diet was reacquired (spontaneous...

Methods of training cattle to avoid a location using electrical cues
Contributor(s):: Lee, C., Prayaga, K., Reed, M., Henshall, J.
Electronic technologies offer new opportunities to control the spatial positioning and social groupings of cattle. This study examines the potential for cattle to be trained by associative learning so that they avoid a feed attractant when cued by electrical stimuli delivered by radio-controlled...

Maternal influence on feeding site avoidance behaviour of lambs
Contributor(s):: Black-Rubio, C. M., Cibils, A. F., Gould, W. R.
Ewes can play a critical role in moulding habitat preferences of their daughters. Little is known, however, about how feeding site preferences of lambs can be modified by manipulating the behaviour of their dams. We conducted an experiment with sheep to investigate the influence of shock-trained...
