“…In general, stereotyped behavior (trough licking, floor licking, and vacuum chewing) were more frequent in animals housed in individual cages, corresponding to 42.95% of total observation time, compared to those housed in collective pens (28.64%), probably due to the small space in the former. Similar results have been reported by Vieuille-Thomas et al (1995), andPandorfi et al (2008). The behavior of rooting solid floor in the absence of any substrate (bedding), demonstrating the need to explore the environment in search of food, characterizes a stereotypy and was not observed in the present study since the assessments were performed up to 3 hours after feeding, when the sensation of satiety prevents the expression of this behavior.…”

Sixteen pregnant sows were used. The experimental design was completely randomized with a 2x2 factorial scheme consisting of two housing systems (individual cages and collective pens) and two diets (low [2.67%] and high [13.14%] level of crude fiber). Physiological, behavioral, environmental, and hormonal parameters were studied. In addition, the following productive and reproductive parameters were evaluated: weight gain, feed intake, feed conversion of the sow and piglets, number of piglets born dead and alive, number and weight at weaning, and backfat thickness of sows. Pregnant sows reared in collective pens and fed a highfiber diet exhibited better physiological responses, indicating greater comfort and better animal welfare. The environmental variables were close to the comfort zone of the animals. In addition to providing a more comfortable environment, housing pigs in collective pens reduced stereotypy, permitting the sows to express a more natural behavior. The high-fiber diet did not interfere with female productive performance. Tifton hay can therefore be indicated as an alternative for the formulation of sow diets to improve animal welfare.

“…Previous works [1,9,31] have already provided evidence that IP-housed sows performed more stereotypies than CP-housed sows and that vacuum chewing was the most prevalent stereotypy observed in IP-housed sows. Stereotypies are generally considered to be related to a welfare deficit [12,27].…”

Urinary cortisol as an additional tool to assess the welfare of pregnant sows kept in two types of housing

et al. 2002

-The use of urinary cortisol (UC) as an additional tool to evaluate sows welfare was assessed in two experiments. In a preliminary methodological experiment, the kinetics of cortisol excretion in urine was studied during an Adreno Cortico Trophic Hormone (ACTH) challenge test in 10 pregnant sows. In a second experiment, 96 primiparous sows of an experimental unit were assigned to two different housing systems: 48 animals were housed in individual pens (IP) and 48 animals in collective pens (CP) with 6 animals per pen. UC was measured at the beginning and at the end of pregnancy and compared with other welfare indicators such as behaviour or skin damage. In both experiments, UC was measured using a high pressure liquid chromatography assay. In experiment 1, UC was constant on the day before injection of ACTH, with no variations related to circadian rhythm. It began to rise 2 h after the injection, peaked between 2 to 5 h after then returned to the basal concentration on the day after the injection. In experiment 2, UC concentrations were not different between CP-and IP-housed sows but they were higher in sows exhibiting the less stereotypies in comparison with sows exhibiting the most stereotypies. The results of this study suggest that UC is a good indicator of acute stress, more convenient than plasma cortisol measurement since it is a non-invasive method avoiding restraint or catheterisation of sows. They also suggest that UC could also give additional information on the assessment of chronic stress and improve the evaluation of animal welfare if used in conjunction with other welfare indicators.pig / urinary cortisol / group housing / stress / welfare Résumé -Le cortisol urinaire comme critère d'évaluation supplémentaire du bien-être de la truie gravide dans deux systèmes de logement.

“…Stereotypic behavior can be defined as "repetitive, invariant behavior patterns with no obvious goal or function" (Mason, 1991(Mason, , p. 1015. Common stereotypic behavioral patterns in domestic swine are often based on oral-nasal activity, such as bar-biting, sham-chewing, drinker-pressing, head-weaving, nose-rubbing, and tongue-rolling (Broom, 1986;Robert, Rushen, & Farmer, 1997;Stolba, Baker, & Wood-Gush, 1983;Vieuille-Thomas, Le Pape, & Signoret, 1995). The addition of substrates such as straw, peat and mushroom compost to swine housing has been shown to decrease common stereotypic behaviors and aggression toward pen mates (Arey, 1993;Beattie et al, 1995;Fraser, Phillips, Thompson, & Tennessen, 1991;Kelly, Bruce, English, Fowler, & Edwards, 2000;Sneddon, Beattie, Walker, & Weatherup, 2001;Wood-Gush & Beilharz, 1983).…”

-The predominant method of measuring welfare in swine focuses on overt physical ailments, such as skin lesions, lameness, and body condition. An alternative metric for assessing welfare in swine can be to measure the frequency and duration of positive behavioral states, such as play. Given that play occurs only when an animal's primary needs (food, comfort, safety, etc.) have been satisfied, it has been suggested that play may be a sensitive indicator for assessing the welfare of non-human animals. Play has primarily been described in young piglets and is assessed via the occurrence of specific play markers. These play markers include overt bursts of energy like scamper, or more subtle social behaviors like nose-to-body contact. This review describes four areas of play for swine: locomotor, object, sow-piglet, and, peer play. From sporadic leaping to combative wrestling, play behavior allows for the fine-tuning of reflexive behavior which can enhance physical development, enrich cognitive abilities, and facilitate the maintenance of social bonds.
