Abstract:Cilj raziskave je bil proučiti sesno obnašanje pujskov v času laktacije glede na telesno maso in spol. V raziskavo je bilo vključenih 14 gnezd s skupno 158 pujski (85 pujskov moškega in 73 pujskov ženskega spola, velikost gnezd 6–15 pujskov, Me = 10,5). Sesno obnašanje, ki smo ga določili kot sesni položaj (izbrani sesek) in stabilnost sesnega reda, smo spremljali za 8 obdobij: do 1. dneva, 2.–4., 5.–7., 8.–11., 12.–15., 16.–20., 21.–25. in 26.–32. dneva starosti pujskov. V teh obdobjih so bili pujski tudi stehtani. Za namen analize sesnega obnašanja smo mamalni kompleks razdelili na tri področja: sprednji (1. in 2. sesni par), srednji (3.–5. sesni par) in zadnji del (6.–8. sesni par). Neodvisno od proučevanih dejavnikov smo potrdili, da i) največ pujskov sesa na srednjih sesnih parih, sledijo sprednji in nato zadnji sesni pari (47 %, 31 %, 22 %); in ii) stabilnost sesnega reda prva dva tedna narašča, nato pa ostane do konca laktacije konstantna. Spol pujskov ne vpliva na stabilnost sesanja, ima pa vpliv na sesni položaj. Pujski moškega spola v enakem odstotku sesajo na sprednjih in zadnjih sesnih parih, pujski ženskega spola pa značilno več na sprednjih v primerjavi z zadnjimi sesnimi pari. V raziskavi smo potrdili vpliv relativne telesne mase na sesni položaj in stabilnost sesanja. Telesna masa od sprednjih proti zadnjim sesnim parom pada. Težji pujski redko sesajo na zadnjih sesnih parih, kar se je izkazalo med celotno laktacijo, ter prej vzpostavijo stabilen sesni red.

Title:The effect of body weight and sex on behaviour lactation
Abstract:The aim of the present study was to examine the suckling behaviour of piglets during lactation with regard to body weight and sex. The study included 14 litters with a total of 158 piglets (85 male and 73 female piglets, litter size 6 to 15 piglets, median of 10.5). Suckling behaviour was defined as the suckling position (the selected teat) and suckling stability, and was observed in 8 periods: 0-1, 2-4, 5-7, 8-11, 12-15, 16-20, 21-25 and 26-32 days of age. During these periods, the piglets were also weighed. For further analysis, the udder was divided into three areas: anterior (1st and 2nd teat pair), middle (3rd-5th teat pair) and posterior part (6th-8th teat pair). Irrespective of the factors studied, we confirmed that i) most piglets suckled in the middle part of the udder, followed by the anterior and posterior part (47%, 31% and 22%, respectively) and ii) suckling stability increased during the first two weeks and remained constant until the end of lactation. Our results showed no effect of piglet sex on suckling stability and a significant effect on suckling position. Male piglets suckled in similar proportions on the anterior and posterior teat pairs, whereas females suckled significantly more often on the anterior than on the posterior teat pairs. The study confirmed the effect of relative body weight on suckling position and suckling stability. Body weight decreases from the anterior towards the posterior part. Heavier piglets rarely suckled at the posterior teat pairs, which was evident throughout lactation, and established a stable suckling order earlier.
