Pre-weaning socialization and environmental enrichment affect life-long response to regrouping in commercially-reared pigs
Contributor(s):: Ko, Heng-Lun, Chong, Qiai, Escribano, Damián, Camerlink, Irene, Manteca, Xavier, Llonch, Pol
Weaning and other regrouping events as routine work in commercial farms cause stress to pigs and compromise their welfare. Several studies found positive outcomes to mitigate weaning stress when piglets were socialized (i.e. co-mingled) or raised with enrichment materials in research settings....
Interaction between sows’ aggressiveness post mixing and skin lesions recorded several weeks later
Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Voß, Barbara, König von Borstel, Uta, Gauly, Matthias
Group housing of pigs leads inevitably to more or less serious agonistic interactions during the establishment of the social rank order of the group. In order to reduce the number of severe agonistic interactions and thus the negative effects on well-being and performance, the use of genetic...
Effect of marginal environmental and social enrichment during rearing on pigs’ reactions to novelty, conspecifics and handling
Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Welp, Stephan, Voß, Barbara, König von Borstel, Uta, Gauly, Matthias
The rearing environment of farmed animals can affect their behaviour when handled, and therefore needs to be taken into account when selecting for traits such as docility. Therefore, 126 German Landrace and Pietrain×German Landrace pigs were reared in two different production environments (barren...
Suckling behaviour and health parameters of sows and piglets in free-farrowing pens
Contributor(s):: Lohmeier, R. Y., Gimberg-Henrici, C. G. E., Burfeind, O., Krieter, J.
The aim of the present study was to investigate the effect of free-farrowing pens and farrowing crates on the health parameters and the suckling behaviour of sows and their piglets, which were housed in farrowing crates (FC; n = 127) and in free-farrowing pens (FP; n = 121). All sows were...
Early socialisation as a strategy to increase piglets’ social skills in intensive farming conditions
Contributor(s):: Salazar, Laura C., Ko, Heng-Lun, Yang, Chung-Hsuan, Llonch, Lourdes, Manteca, Xavier, Camerlink, Irene, Llonch, Pol
Socialisation is a process in which animals interact with unfamiliar conspecifics, that allows them to develop their social abilities. Socialisation has been proposed as a method in pig husbandry to increase piglets’ social skills and reduce conspecific aggression, which is a major welfare issue...
Relationships among aggressiveness, fearfulness and response to humans in finisher pigs
Contributor(s):: O’Malley, Carly I., Wurtz, Kaitlin E., Steibel, Juan P., Bates, Ronald O., Ernst, Catherine W., Siegford, Janice M.
Mixing unfamiliar pigs is common in modern production, resulting in intense aggression potentially leading to injury and stress. One solution is breeding against aggressiveness. However, in order to anticipate the consequences of such selection, we need to understand how individual aggressiveness...
Associations between the dominance status and sexual development, skin lesions or feeding behaviour of intact male pigs
Contributor(s):: Parois, Severine, Larzul, Catherine, Prunier, Armelle
In boars, social relationships could influence pubertal development and feeding behaviour. The objectives of the present study were to determine the relationships between behaviour (agonistic, mounting and feeding behaviours), plasma sex steroids (oestradiol, testosterone) and fat androstenone. A...
Identifying blood-based biomarkers associated with aggression in weaned pigs after mixing
Contributor(s):: Shen, Chunyan, Tong, Xian, Chen, Ruonan, Gao, Siyuan, Liu, Xinpeng, Schinckel, Allan P., Li, Yuan, Xu, Feilong, Zhou, Bo
Animal behavior, including agonistic behavior, is regulated by various neurotransmitters and hormones in the blood. To Identify blood-based biomarkers associated with aggression in weaned pigs after mixing, a total of 500 weaned pigs from 65 litters were selected and mixed into 51 pens with...
Application of the welfare quality protocol in pig slaughterhouses of five countries
Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.
The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...
Welfare effects of a disease eradication programme for dairy goats
| Contributor(s):: Muri, K., Leine, N., Valle, P. S.
The Norwegian dairy goat industry has largely succeeded in controlling caprine arthritis encephalitis (CAE), caseous lymphadenitis (CLA) and paratuberculosis through a voluntary disease eradication programme called Healthier Goats (HG). The aim of this study was to apply an on-farm welfare...
Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs
| Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.
Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...
Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing
| Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.
Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...
Straw applications in growing pigs: effects on behavior, straw use and growth
| Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.
The short-term effects of four straw applications on pigs housed on slatted floors were investigated to determine differences in behavior, straw use and growth. Both the type of straw used and the design of the application might influence the attractiveness and effectiveness of the applications....
Analysis of the phenotypic link between behavioural traits at mixing and increased long-term social stability in group-housed pigs
| Contributor(s):: Desire, S., Turner, S. P., D'Eath, R. B., Doeschl-Wilson, A. B., Lewis, C. R. G., Roehe, R.
Mixing of growing pigs results in aggressive contests between group members. As aggression serves to establish dominance relationships, it is possible that increased initial aggression may facilitate the formation of social hierarchies. The objective of the study was to investigate whether there...
Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds
| Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.
In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

Isolation of Microsporum canis from the hair coat of pet dogs and cats belonging to owners diagnosed with M. canis tinea corporis
| Contributor(s):: Cafarchia, C., Romito, D., Capelli, G., Guillot, J., Otranto, D.
Microsporum canis has been frequently isolated from human cases of tinea capitis and tinea corporis. The infection may be acquired from infected animals with cutaneous lesions but also from asymptomatic carriers or from the environment. As asymptomatic M. canis carriers are considered to be a...
