Half were housed in spacious ‘enriched’ pens with straw bedding
pigs really do have something to say
The grunts made by pigs vary depending on the pig’s personality and can convey important information about the welfare of this highly social species, new research has found.
canada goose outlet in uk Scientists specialising in animal behaviour and welfare devised an experiment to investigate the relationship between cheap canada goose uk personality and the rate of grunting in pigs. They also examined the effect different quality living conditions had on these vocalisations. canada goose outlet in uk
canada goose outlet mississauga Findings from the study, carried out by researchers from the University of Lincoln, UK, and Queens University Belfast, are published in the Royal Society journal Open Science today (29th June 2016). canada goose outlet mississauga
The study involved 72 cheap Canada Goose male and female juvenile pigs. Half were housed in spacious ‘enriched’ pens with straw bedding, while the other half were kept in more compact ‘barren’ pens with partially slatted concrete floors, which adhered to UK welfare requirements.

Each pig spent three minutes in social isolation, and five minutes canada goose uk outlet in a Canada Goose Online pen with a large white bucket or an orange traffic cone they had not previously encountered. Their behaviour, including vocalisations, were observed. These tests were repeated two weeks later, allowing the researchers to determine if the pigs’ responses were repeatable the defining characteristic of personality (also known as ‘coping style’ in animals). canada goose jacket outlet

The study also Canada Goose Jackets found that male pigs (but not females) kept in the lower quality conditions made fewer grunts compared with those housed https://www.dvu-nds.de in the enriched Canada Goose online environment, canada goose coats suggesting greater susceptibility among male pigs to environmental factors. canada goose outlet houston

This may have had far reaching consequences in shaping the evolution of social canada goose behaviours, the researchers believe.

Principal investigator, Dr Lisa Collins, a uk canada goose outlet specialist in animal health, behaviour and welfare epidemiology in the School of Life Sciences at the University of Lincoln, said: “The domestic pig is a highly social and vocal species which uses canada goose uk shop acoustic signals in a variety of ways; maintaining contact with other group members while foraging, parent offspring communication, or to signal if they are distressed.
canada goose outlet china “The sounds they make convey a wide range of information such as the canada goose outlet emotional, motivational and physiological state of the animal. For example, squeals are produced when pigs feel fear, and may be either alerting others to their situation or offering assurance. Understanding how the vocalisations of pigs’ relate to their personality will also help animal behaviourists and welfare experts have a clearer picture of the impact those personalities have on communication, and thus its role in the evolution of social behaviour and group buy canada goose jacket cheap dynamics in social species.” canada goose outlet china.
