Tail Docking of Canine Puppies: Reassessment of the Tail's Role in Communication, the Acute Pain Caused by Docking and Interpretation of Behavioural Responses
out of 5 stars
| Contributor(s):: David J Mellor
Laws, regulations and professional standards increasingly aim to ban or restrict non-therapeutic tail docking in canine puppies. These constraints have usually been justified by reference to loss of tail participation in communication between dogs, the acute pain presumed to be caused during...
Tail Docking and Ear Cropping Dogs: Public Awareness and Perceptions
| Contributor(s):: Katelyn E. Mills, Jesse Robbins, Marina A. G. von Keyserlingk
Tail docking and ear cropping are two surgical procedures commonly performed on many dog breeds. These procedures are classified as medically unnecessary surgeries whose purpose is primarily cosmetic. Available attitude research surrounding these controversial practices has been limited to...
Dogs' body language relevant to learning achievement
| Contributor(s):: Hasegawa, M., Ohtani, N., Ohta, M.
The facial expressions and body postures of dogs can give helpful information about their moods and emotional states. People can more effectively obedience train their dogs if we can identify the mannerisms associated with learning in dogs. The aim of this study was to clarify the dog's body...
Tales about tails: is the mutilation of animals justifiable in their best interests or in ours?
| Contributor(s):: Edwards, S., Bennett, P., Appleby, M. C., Weary, D. M., Sandoe, P.
Tail docking, involving surgical or non-surgical removal of a portion of the tail, is one of the most widely carried out and contentious mutilations inflicted by humans on animals. To differing extents, this procedure is carried out on farm livestock, draught animals and companion animals. The...
A combination of behavioral and physiological indicators for assessing pig welfare on the farm
| Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.
The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...
Scientists and Dutch pig farmers in dialogue about tail biting: unravelling the mechanism of multi-stakeholder learning
| Contributor(s):: Benard, M., Schuitmaker, T. J., Buning, T. de C.
Pig farmers and scientists appear to have different perspectives and underlying framing on animal welfare issues as tail biting and natural behaviour of pigs. Literature proposes a joint learning process in which a shared vision is developed. Using two different settings, a symposium and...
Vocal recognition of owners by domestic cats ( Felis catus)
| Contributor(s):: Saito, A., Shinozuka, K.
Domestic cats have had a 10,000-year history of cohabitation with humans and seem to have the ability to communicate with humans. However, this has not been widely examined. We studied 20 domestic cats to investigate whether they could recognize their owners by using voices that called out the...

A case control study of on-farm risk factors for tail biting in pigs

An investigation into the effect of different protein and energy intakes on model tail chewing behaviour of growing pigs
| Contributor(s):: McIntyre, J., Edwards, S. A.
Twenty-four crossbred pigs were housed individually and allocated at 62 kg (S.E.M.=0.81) to one of three diets providing differing daily protein and energy intakes: control (C) 1.42 g CP/MJ DE, fed to provide 2.85 maintenance energy; low protein (LP) 0.76 g CP/MJ DE fed to provide the same daily...
Effects of an oral dose of acetyl salicylate at tail docking on the behaviour of lambs aged three to six weeks
| Contributor(s):: Pollard, J. C., Roos, V., Littlejohn, R. P.
To investigate a practical method of providing analgesia for docking of lambs' tails, the effectiveness of an oral dose of aspirin (acetyl salicylate) in reducing discomfort behaviour immediately following application of elastrator rings, was evaluated. The study, conducted in New Zealand,...
Validation of a method for assessment of an acute pain in lambs
| Contributor(s):: Molony, V., Kent, J. E., McKendrick, I. J.
Acute pain following different methods of rubber ring castration and tail docking (CTD) was assessed using behavioural and physiological methods. Validity was determined by showing how accurately lambs were allocated, to their appropriate treatment groups. Six groups of seven lambs, 5-6 days old,...
Behaviour of two genotypes of growing-finishing pig in three different housing systems
| Contributor(s):: Guy, J. H., Rowlinson, P., Chadwick, J. P., Ellis, M.
This trial compared the behaviour of 720 growing-finishing pigs, progeny of either indoor (Large White x Landrace) or outdoor (part-Meishan or part-Duroc) sows mated to Large White boars, when housed in either outdoor paddocks, straw yards or fully-slatted pens. Space allowance per pig in outdoor...
Does balancing for color affect pigs' preference for different flavored tail-models?
| Contributor(s):: Jankevicius, M. L., Widowski, T. M.
In previous work using rope flavored with various solutions as a model to study tail biting, pigs generally show a preference for the blood-flavored models compared to untreated models or models soaked in NaCl solutions or different fractions of blood. However, in these studies tail models were...
Reducing feather pecking when raising laying hen chicks in aviary systems
| Contributor(s):: Huber-Eicher, B., Sebo, F.
Aviary systems for laying hens offer several advantages over battery cages. However, pecking the feathers of conspecifics remains a serious problem that negatively affects the welfare of the birds as well as the economy of a farm. From experimental studies with small groups, it has been shown...
The effect of breed on the development of adverse social behaviours in pigs
| Contributor(s):: Breuer, K., Sutcliffe, M. E. M., Mercer, J. T., Rance, K. A., Beattie, V. E., Sneddon, I. A., Edwards, S. A.
Tail-biting and other harmful social behaviours are a common problem on pig farms. The aims of the current experiment were (1) to investigate the genetic component of harmful social behaviours such as tail-biting by assessing breed differences, and (2) to further investigate the reliability and...
The effects of prior experience of straw and the level of straw provision on the behaviour of growing pigs
| Contributor(s):: Day, J. E. L., Burfoot, A., Docking, C. M., Whittaker, X., Spoolder, H. A. M., Edwards, S. A.
Straw improves the welfare of pigs housed in barren environments as it can act as a recreational and/or nutritional substrate and provide for physical and thermal comfort. However, it is unknown how much straw must be provided to be behaviourally rewarding and whether pigs' prior experience of...

Effects of species-relevant environmental enrichment on the behaviour and productivity of finishing pigs
| Contributor(s):: Weerd, H. A. van de, Docking, C. M., Day, J. E. L., Breuer, K., Edwards, S. A.
Three different enrichment objects, which were designed according to pig-specific requirements, were provided to groups of growing pigs with undocked tails. The enrichment treatments were a substrate dispenser providing straw, a rootable feed dispenser providing flavoured feed and a liquid...
