'subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity
Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.
In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...
A behavioural study of growing pigs in different environments
Contributor(s):: Ruiterkamp, W. A.
The full-slat system, the half-slat system (both without substrate) and the Danish system consisting of a lying area supplied with straw and a separated dunging area were compared. Two types of pigs were used; those born and reared in a bare slat pen without any substrate and those in a pen with...
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...
A comparison between leg problems in Danish and Swedish broiler production
Contributor(s):: Sanotra, G. S., Berg, C., Lund, J. D.
In Denmark and Sweden, surveys were undertaken to estimate the prevalence of leg problems in conventional broiler production. The Danish survey included 28 Ross 208 flocks, and the Swedish survey included 15 Ross 208 and 16 Cobb flocks. Leg problems included reduced walking ability (gait), tibial...
A comparison of wooden slats and straw bedding on the behaviour of sheep
Contributor(s):: Gordon, G. D. H., Cockram, M. S.
The behaviour of 2 groups of sheep was observed when they were placed in a pen on wooden slats and/or straw bedding for 48 h. When sheep were placed in the pen and not given a choice of slats and straw, the proportion of scans spent standing and lying by one group of sheep were not affected by...
A complex automatic feeding system for pigs aimed to induce successful behavioural coping by cognitive adaptation
Contributor(s):: Ernst, K., Puppe, B., Schon, P. C., Manteuffel, G.
In modern intensive husbandry systems there is an increasing tendency for animals to interact with technical equipment. If the animal-technology interface is well-designed this may improve animal welfare by offering challenges for cognitive adaptation. Here a system and its application is...
A cross-sectional study of prevalence and risk factors for foot lesions and abnormal posture in lactating sows on commercial farms in England
Contributor(s):: Kilbride, A. L., Gillman, C. E., Green, L. E.
A cross-sectional study of lactating sows in 71 commercial pig herds in England was carried out to estimate the prevalence of foot lesions and abnormal posture and investigate the associated risks. Observational data were collected on the standing posture, lesions on the hind left foot, and the...
A cross-sectional study of the prevalence of lameness in finishing pigs, gilts and pregnant sows and associations with limb lesions and floor types on commercial farms in England
The prevalence and risks for abnormal gait in finishing pigs (Sus scrofa), gilts and pregnant sows from a representative cross-section of indoor and outdoor herds in the United Kingdom were investigated. The prevalence of abnormal gait in finishing pigs, maiden gilts, pregnant gilts and pregnant...
A descriptive survey of the range of injuries sustained and farmers' attitudes to vulva biting in breeding sows in south-west England
Contributor(s):: Rizvi, S., Nicol, C. J., Green, L. E.
The within-farm prevalence of vulva biting in breeding sows in south-west England was investigated using a postal survey sent to 410 pig farmers in January 1997. The response rate was 65% and there were 83 usable replies. The majority of farms where vulva biting was reported indicated a low...
A different cut? Comparing attitudes toward animals and propensity for aggression within two primary industry cohorts - farmers and meatworkers

A field assessment of the effect of pre-slaughter conditions and genetic-stress susceptibility on blood welfare indicators in pigs

A flooring comparison: the impact of rubber mats on the health, behavior, and welfare of group-housed sows at breeding
Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Richert, B. T., Pajor, E. A.
Comfortable flooring may impact many aspects of an animal's welfare, including lying behavior, an animal's ability to change postures, and incidence of lameness and lesions. Therefore, we hypothesized that the addition of rubber mats to stalls of group pens would improve sow health, comfort and...
A meta-analysis of the combined effect of housing and environmental enrichment characteristics on the behaviour and performance of pigs
Contributor(s):: Averos, X., Brossard, L., Dourmad, J. Y., Greef, K. H. de, Edge, H. L., Edwards, S. A., Meunier-Salaun, M. C.
To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were applied to evaluate the effects of space...

A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances
Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.
Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...
A multiple free choice model for pigs
Contributor(s):: Mwanjali, S., Smidt, D., Ellendorff, F.
A model which takes into consideration previous criticism of multiple free choice systems is proposed. A hexagonal housing system was constructed with 6 identical cubicles, which allowed elimination of all variables except the 1 to be investigated. Barriers could be introduced at the entrance to...
A note on contrafreeloading in broilers compared to layer chicks
Contributor(s):: Lindqvist, C., Zimmerman, P., Jensen, P.
Contrafreeloading (CFL) is the behaviour where an animal chooses to work for food even when identical food can be obtained without any effort. Previous studies have suggested that the difference in CFL between White Leghorn layers and jungle fowl may be a side effect of selection for increased...
A note on genetic parameters for estrus symptoms in sows
Contributor(s):: Gade, S., Bennewitz, J., Kirchner, K., Looft, H., Knap, P. W., Thaller, G., Kalm, E.
Showing clear estrus symptoms contributes to the reproductive effectiveness of a sow. The aim of the study was to estimate genetic parameters and breeding values for estrus symptoms, a trait which included swelling and reddening of the vulva, interest in the boar and strength of the standing...
A note on genetic parameters of gilt responses to humans
Contributor(s):: Hellbrugge, B., Tolle, K. H., Presuhn, U., Krieter, J.
In this study, a response test towards a stockperson was evaluated for improved maternal behaviour and increased piglet survival. Records were available from 638 German Landrace gilts with 860 observations tested for the response to an observer in the familiar environment of the mating centre....
A note on nursing termination and resting behaviour of suckling piglets
Contributor(s):: Petherick, J. C.
Observations were carried out on 8 Large White x Landrace sows and their litters housed in either large straw-bedded pens, or conventional farrowing pens. The animals were observed for periods during the 8 days following parturition. Sows in the straw-bedded pens had built nests into which the...
