Are low, of the observed time higher IGEg pigs spent less on aggressive biting of pen mates, and significantly less on oral manipulation within the form of biting the ears of pen mates than low IGEg pigs did (Table).High IGEg pigs weren’t only biting their pen mates less, but also their environment.They had been chewing less on the distraction materials offered, which were the chain with ball and jute sack (Table).Higher IGEg pigs have been much more normally observed to perform comfort behaviour, which include scratching the skin (Table).Similar towards the nursery phase, high IGEg pigs tended to urinate and defecate less than low IGEg pigs (Table).There was no difference among the IGEg groups in general activity (P ), explorative behaviour (P ), or aggressive behaviour (P ).There was a important interaction in between IGEg group and housing situation for lying inactive (P ) and locomotion (P ), see Table , and there tended to become G E interactions for comfort behaviour, drinking, penData Analyses Statistical analyses have been performed using SAS (SAS Institute Inc).Data had been analysed and presented by production phase as applied in industrial pig farming to facilitate comparison amongst animal behaviour research.The nursery phase is from to weeks of age, whereas the finishing phase is generally from weeks of age till slaughter (here at weeks of age).Behavioural scans had been analysed on pen level (n ) and averaged more than production phase (nursery phase observations weeks , , and ; finishing phase observations weeks , , and).Hereto the behaviours of pigs were averaged by pen ( pigspen).Residuals with the response variables were checked for normality, and if necessary, behaviours have been arcsine square root transformed.Behaviours by pen and production phase had been analysed inside a common linear model (GLM procedure), and integrated IGEg group, housing condition, the interaction between IGEg group and housing condition, and batch as fixed class effects.The weekly tail harm scores were averaged into two scores per pig, one for the nursery phase (weeks) and 1 for the finishing phase (weeks).Scores had been analysed at person animal level (n ) inside a generalized linear mixed model (MIXED process) with IGEg group, housing condition, the interaction between IGEg group and housing situation, sex, and batch as fixed class effects, and as random aspect pen nested within IGEg group, housing situation and batch.The total cm of `consumed’ jute sacks per pen (from weeks) was analysed at pen level (n ) inside a common linear model (GLM process) with IGE group, housing situation, the interaction in between IGE group and housing situation, and batch as fixed class effects.To facilitate the GSK0660 interpretation of consumed bags in cm, outcomes are presented in number of jute sacks consumed [total cm].Impact of Housing Condition on Behaviour Enrichment with straw significantly influenced practically all behaviours during the nursery and finishing phase (Tables ,).Pigs in enriched pens had been much more active in comparison to pigs in barren pens, which was observed from much less time spent on sleeping, lying inactive and standing.Pigs in enriched pens specifically showed much less tail biting, ear biting, and belly nosing, and alternatively spent additional time on play, comfort behaviour, and nosing and rooting the pen than pigs in barren pens.Tail Damage Scores Pigs PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21308498 currently showed tail damage in the moment of weaning, with an typical tail damage score of .(Fig.).Throughout the nursery phase (weeks) there was nodifference amongst the IGEg groups for tail damag.
