Abstract:Odstavitev pujskov od svinje predstavlja eno najbolj stresnih faz reje prašičev. Da bi zmanjšali agresijo/stres ob odstavitvi in izboljšali rastnost pujskov, smo uporabili metodo imprintinga (vtisnjenja). Pujski so bili v obdobju laktacije izpostavljeni preprostim 2-D simbolom (črn križ na beli podlagi – ČK in bel krog na črni podlagi – BK). Vsaka odstavljena skupina je bila sestavljena iz pujskov dveh gnezd; polovica pujskov iz gnezda ČK, druga polovica pa iz gnezda BK. Odstavitveni boks testne skupine je bil virtualno razdeljen na polovico, pri čemer je bila vsaka označena z istovrstnim znakom, tj. ČK in BK del boksa. V boksu kontrolne skupine ni bilo nameščenih 2-D simbolov. Rezultati so pokazali boljše priraste v testnih skupinah (12–17 % višji dnevni prirast). Stopnja agresije (bojev) je bila nižja v testnih skupinah, pri čemer se je večina bojev (62–75 %) odvila med osebki različnih gnezd. Odstavljeni pujski so kazali značilno tendenco zadrževanja (grupiranja) na delu odstavitvenega boksa, označenim z znanim 2-D simbolom (p < 0,05). Ugotovili smo, da virtualna predeljenost odstavitvenih boksov s pomočjo preprostih 2-D simbolov predstavlja učinkovito metodo za spodbujanje teritorialnega obnašanja pujskov in posledično za zmanjšanje odstavitvene agresije in izboljšanje rastnosti odstavljenih pujskov v farmskih pogojih reje.

Title:Mitigation post-weaning aggression and stress based on the piglets imprinting during lactation
Abstract:Weaning stress accompanied by outburst of aggression is a critical point in pig production. In the present study, a simple practical approach based on the imprinting phenomenon to improve weaned piglets’ welfare and growth performance was implemented. From birth, piglets were continually exposed to the simple 2D shapes, either a white circle on a black background (WC) or a black cross on a white background (BC). At weaning, piglets were allotted to weaning groups consisting of one WC and one BC litter, whereby test weaning pens, but not the control pens, were virtually divided using WC and BC signage on respective halves of the pen. The results revealed better growth performance of the test group (12–17 % higher daily gain). On the whole, the number of post-weaning fights was lower in the test group and the majority of fights (62–75 %) occurred among WC and BC. As regards the territoriality, piglets post-weaning tendency to remain in the area marked with a familiar sign was in general significant – i.e. more distinct grouping in the test pens (p < 0,05). It appears that virtual splitting of weaning pens using simple 2D symbols to which pigs were exposed during lactation may decrease weaning aggression, promote distinct grouping and territorial behaviour, and promote growth performance of weaned piglets under farm conditions.
