“…Digging behavior is strongly related to eating behavior; it was observed by Massari et al (2015) that domestic pigs exploit the environment in search of food. However, Stevenson (2000) found that under natural breeding conditions, pigs spent about 75% of their time in activities such as digging, searching for food and exploring the environment; confinement in highly stocked bins without environmental enrichment makes it impossible to perform these behaviors.…”

The aim of this study was to analyze the behavior of pigs housed in facilities with different building typologies in terms of the floor and partitions. Two treatments were compared: a pen containing an area with a depth of water, and a pen floor with leaked on the sides. Data on swine behavior were collected over seven days, and the pigs' positions (standing, sitting, and lying down) and activities (eating, drinking, digging, interacting, walking and idling) were observed for five animals in each pen. Data were collected via visual measurement every 10 minutes and an ethogram was constructed. Measurements of environmental data were taken (dry bulb temperature, globe temperature and relative humidity), and were used to calculate the black globe temperature and humidity index. Although the pens showed differences in terms of the dry bulb temperature, this temperature can be considered thermoneutral for creation in the growth and termination phases. Animals housed in the pens with an area of water depth stood for longer, possibly due to the environmental enrichment caused by the presence of the water slide.

“…We hypothesized that if different time intervals were used in behavioral sampling, this would result in different behavioral frequencies for the focal behaviors from those measured during continuous observation. Massari et al (2015) employed the focal animal methodology previously proposed by Altmann (1974) with 15 min of observation and 3-min intervals to assess typical behaviors (standing, lying, and eating) and continuous observation for dynamic behaviors (social interaction and agonistic, exploratory, and stereotypic behaviors) to compare the behavior of pigs in the grower and finisher phases using the "wean to finish" system. That methodology suggests that intervals and observation period must be determined according to the characteristics of each behavior.…”

The objective of this work was to study the behavior of swine females in the grower phase using different observation intervals (continuous, 5, and 10 min). A total of 42 swine were used, 14 of them for each treatment, which were identified with a marker stick. These animals were observed using the focal sampling method for 5 h. The treatments were the observation intervals: continuous, every 5 min, and every 10 min. Among the behaviors analyzed during the experiment, the different observation intervals did not affect the estimated time spent in the activities. Time observation intervals of 10 min or less adequately describe the duration of the main behavioral parameters of female pigs in this setting.

“…The high frequency of visits and the act of projecting the head toward the drinking fountain, triggering the system without drinking water properly (drinker-playing) (Chen et al, 2020), as seen in the bed systems, especially in pens with wood shavings substrate, can be interpreted as stereotypies or obsessive behavior (Maia et al, 2013;Massari et al, 2015).…”

“…Piglets may exhibit changes in their behavior patterns depending on the environment in which they are kept. Massari et al (2015) state that "eating" behavior has an inverse relationship with air temperature and a strongly positive relationship with exploratory behaviors and agonistic interactions, since exploratory behaviors are often related to the search for food.…”

“…This result is possibly due to the thermal stress in which all animals, regardless of treatment, were experiencing. Authors such as Kiefer et al (2010), Debreceni et al (2014), and Massari et al (2015) indicate that this behavioral pattern is closely related to the thermal environment and that animals under heat stress increase their time spent lying down. The strong positive correlation between the thermal and behavioral variables is due to the animals' attempt to increase heat exchange with the floor, which is cooler, in addition to reducing the production of metabolic heat by avoiding activity.…”

Behavioral Responses of Pigs Finished in Deep Bedding and Conventional Bed Systems

et al. 2021

The objective of this study was to characterize the thermal environment and evaluate the behavior of finishing pigs housed in deep bedding and conventional systems. The work was carried out in the Department of Animal Science of the Federal Institute of Education, Science and Technology of Southeast Minas Gerais, Rio Pomba campus. Three pens were used in an installation for breeding pigs in their finishing phase. Two pens contained deep bedding, with wood shavings and rice husks. The remaining pen was a conventional system. The behavior of the piglets was observed from 8 a.m. to 5:30 p.m., noting the behaviors with the use of an ethogram, while data relating to the thermal environment in the stalls were automatically collected using data loggers. Thermal environment data for all systems presented thermal stress conditions. Regarding behavioral variables, animals in conventional systems had a higher frequency of visits to feeders, while animals in the deep bedding system were more active and visited the drinking fountains more frequently. Despite the higher level of activity of the animals in the deep bedding system, it is not possible to confirm that the deep bedding provides a better degree of well-being for the animals under thermal stress conditions.
