Abstract:Cilj raziskave je bil ugotoviti povezavo med položajem v sesnem redu in agonističnimi vedenjskimi vzorci (agresivno obnašanje) pri pujskih po odstavitvi. V raziskavo je bilo vključenih 120 pujskov iz 12 različnih gnezd. V laktaciji smo opazovali položaj pujskov na mamalnem kompleksu in jih ustrezno označili. V drugem delu poskusa pa smo v obdobju od odstavitve do 18. dne opazovali agresivne dogodke (agresivno obnašanje) med pujski. Pujski, ki so v obdobju laktacije sesali na sredinskem delu mamalnega kompleksa (Sr), so bili pogosteje vključeni v agresivno obnašanje. Prvi dan po odstavitvi so bili pujski Sr vključeni v več kot polovico (64,1 %) situacij agresivnega obnašanja, manj (29,6 %) so bili vključeni pujski s sprednjega dela mamalnega kompleksa (S). Agresivnega obnašanja, v katerega so bili vključeni pujski zadnjega dela mamalnega kompleksa (Z), je bilo v času opazovanja bistveno manj (6,3 %). Največ agresivnega obnašanja se je zgodilo v prvih 24 urah po odstavitvi, že naslednji dan se je število primerov agresivnega obnašanja prepolovilo (53 %). Trend padanja se je nadaljeval tudi v nadaljnjih dneh po odstavitvi. Število agresivnih dogodkov je bilo v negativni povezavi s povprečno dnevno konzumacijo. V raziskavi smo tako ugotovili, da ima sesni red pomemben vpliv na vzpostavljanje socialnega reda v odstavitveni skupini, katerega pomemben del so tudi agonistične interakcije, t.j. agresivno obnašanje, v katere so bili pujski s sredinskega dela mamalnega kompleksa bistveno bolj vključeni.

Title:The role of position in suckling order on aggressive behaviour of piglets after weaning
Abstract:The aim of this study was to research the link between suckling order and agonistic behavioural patterns (aggressive behaviour) of piglets after weaning. A total of 120 piglets from 12 different litter were included in study. During lactation, piglets' position on mammary complex was determined and properly marked. From weaning to post-weaning day 18 aggressive behaviour among piglets were evaluated. Piglets which suckled in the central part of the mammary complex (Sr) during lactation were more often involved in aggressive behaviour. On the first day after weaning, Sr piglets were involved in more than half (64.1 %) of the situations involving aggressive behaviour, while the piglets from the front of mammary complex (S) were involved in fewer such situations (29.6 %). In the period of the observations, significantly less aggressive behaviour (6.3 %) was observed for piglets from the rear part of mammary complex (Z). The majority of aggressive behaviour occurred in the first 24 hours after weaning. Aggressive behaviour decreased by half (53 %) on the next day and the downward trend continued in the subsequent days after weaning. The number of aggressive events was negatively related to the average feed daily intake. In conclusion, suckleling order has a significant impact on the establishment of social order in the weaning group. Agonistic interactions, i.e. aggressive behaviour, have an important role on the suckling order and it has been shown that piglets from the center of the mammary complex were much more involved in it.
