“…Shoulder ulcers are also commonly observed in lactating pigs kept in a farrowing crate 107 . Further, pigs can also naturally develop arthritis 42,106 . Compared to acute models using inflammatory agents, the natural disease progression includes aspects of ageing and degeneration 42 , which provide a more complete clinical representation of the disease in humans 72 .…”

“…Further, pigs can also naturally develop arthritis 42,106 . Compared to acute models using inflammatory agents, the natural disease progression includes aspects of ageing and degeneration 42 , which provide a more complete clinical representation of the disease in humans 72 . Ethically, the naturally occurring pain conditions are obviously less problematic than other pain models, as pigs are potentially relieved from pain (refinement method).…”

“…As mentioned above, neuropathic pain models seem to reflect the clinical picture better in pigs than in rodents 34,63,64 . Naturally occurring diseases linked to longterm conditions and degeneration 42,106,107 are more representative of human condition in pigs than in rodents due to the pig's lifespan and bodyweight. The size of the pig also allows for assessment methods more similar to those used in humans, for example EEG 123,130 .…”

“…Literature search for human pain models. The most recent reviews on pain assessment all conclude that the pain assessment methods currently used in pigs are insufficient 27,30,42,43 . To suggest relevant areas for improvement of pain assessment in pigs, we qualitatively compared pain assessment methods in pigs to those used in humans.…”

“…Accordingly, in piglets, at lower nest temperatures were associated with more hanging and tucking down tail positions. Tail position has recently been proposed as an indicator of tail biting damage in piglets; however, it has also been observed to be an indicator of an impaired health condition [ 71 ], negative emotional state, fear and pain in piglets [ 72 , 73 , 74 , 75 ].…”

Piglets experience welfare issues during the nursery phase. This pilot study aimed to test a protocol for identifying the main welfare issues in suckling piglets and to investigate relationships among animal-based indicators and management conditions. Litters (n = 134), composed of undocked and tail-docked piglets, were assessed at two farms. After birth, observations were made at the age of 7 days and 20 days. At each observation, housing conditions (HCs) were measured, and 13 animal-based indicators, modified from Welfare Quality, Classyfarm, Assurewel and others introduced ex novo, were recorded. A generalized linear mixed model was used, considering animal-based indicators as dependent variables and farm, piglets’ age, tail docking and HCs as independent variables. The main welfare issues were lesions of the limb (32.6%) and the front area of the body (22.8%), a poor body condition score (BCS) (16.1%), ear lesions (15.5%), and tail lesions (9.7%). Negative social behaviour (e.g., fighting and biting) represented 7.0% of the active behaviour, with tail biting observed in 8.7% of the piglets. While lesions on the front areas of the body were mostly associated with the farm, tail lesions, low BCS, tear staining, and diarrhoea were associated with light and nest temperature (p < 0.05). In particular, tail biting increased with scarce light (p = 0.007). Tail docking did not influence any animal-based indicator except for tear staining which was higher in the tail-docked as compared to the undocked piglets (p = 0.05), increasing awareness on this practice as a source of negative emotion in piglets. The protocol tested may be a promising tool for assessing on-farm piglets’ welfare.

Dairy calves show behavioural responses to hot iron disbudding after local anaesthesia with procaine

Background: The efficacy of procaine as anaesthetic for disbudding of calves is largely unknown. Likewise, information about effect of interval from local anaesthesia to disbudding and the size of the hot iron used is missing. Methods: A total of 167 dairy calves were disbudded after cornual nerve block with procaine. Time from administration of anaesthetic to disbudding varied, and calves were disbudded using two different sizes of hot iron. The calves' behavioural responses to disbudding were recorded based on (1) getting up, (2) kicking, and (3) lifting head. Using logistic regression, the associations between calves showing at least one of these three behaviours and interval from administration of anaesthetic to disbudding and size of the hot iron were evaluated. Results: Overall, 42% of calves showed at least one of the three behaviours, even though they had received a cornual nerve block prior to disbudding. Using the large hot iron was associated with a 2.3 times higher odds of the calf reacting behaviourally compared to the small iron. Interval from administration of anaesthetic to disbudding was not significantly associated with the odds of behavioural responses. Conclusion: Approximately 40% of calves disbudded after cornual nerve block with procaine showed signs of inadequate local anaesthesia. This was especially problematic when hot irons with larger tips were used.
