20.500.12556/DKUM-80626 Vrstni red rojenih pujskov in njegova povezanost s sesanjem na preferenčnem sesnem paru - študija primera Order of born piglets and its relationship with suckling on a preferential teat pair - a case study Cilj preliminarne raziskave je bil ugotoviti, ali in kako je vrstni red rojstva pujskov povezan s stabilnostjo sesnega reda, obiskovanjem preferenčnih sesnih parov in parametri rastnosti. V raziskavi smo spremljali gnezdo s 14 pujski. Pri porodu smo za vsakega pujska zabeležili čas rojstva ter čas in sesek prvega sesanja. Pujske smo tehtali 1., 15. in 30. dan laktacije. Za 1., 15. in 30. dan laktacije smo določili tudi stabilnost sesnega reda in zabeležili seske, na katerih so sesali (skupno 8 sesanj dnevno). Pujske smo glede na zaporedje pri rojstvu razdelili na prve (1.-4.), srednje (5.-10.) in zadnje (11.-14.). Stabilnost sesnega reda za prvi dan je bila v povprečju 0,24 in je bila precej (a neznačilno) višja za pujske, ki so bili rojeni prvi. Stabilnost sesnega reda 15. in 30. dan je bila 0,98 in 1. Pujski, skoteni prvi, so po vzpostavitvi sesnega reda pogosteje sesali na sprednjem delu vimena (1.-3. sesni par), tisti, skoteni med zadnjimi, pa pogosteje na zadnjih seskih (7., 8. sesni par). Pujski, ki so se skotili prvi, so imeli boljšo rastnost kot zadnje rojeni. Ugotovili smo tudi pozitivne srednje močne korelacije (r≈0,60; p The present preliminary study aimed to determine the relationship between birth order and suckling stability, suckling on the preferential teats, and the growth performance. One sow with 14 piglets was included in the experiment. At the farrowing, the birth time and the time and location (teat) of the first suckling was recorded for each piglet. Piglets were weighed on the 1st, 15th and 30th day of lactation. On the same days, suckling order stability was calculated and suckling location recorded (a total of 8 sucklings per day). Respecting birth order, piglets were divided into first (1st-4th), middle (5th-10th) and last born (11th-14th). On the 1st day of lactation, the suckling order stability was 0.24 and was considerably (but not significantly) higher for first born piglets. The suckling order stability of the 15th and 30th day was 0.98 and 1. After the suckling order was established, the first born piglets suckled more often on the anterior part of the udder (1st-3rd teat pair), and those born last suckled more often on the posterior part (7th, 8th teat pair). The first born piglets showed better growth performance as compared to last born piglets.
