20.500.12556/DKUM-68397 Sesno obnašanje pujskov v individualnih in skupinskih prasitvenih boksih Piglets' suckling behaviour in individual and group farrowing systems Cilj raziskave je bil ugotoviti lastnosti sesnega obnašanja v skupinskih prasitvenih boksih in ugotovitve primerjati s konvencionalnimi, t.j. individualnimi prasitvenimi boksi. V raziskavo je bilo vključenih 129 pujskov iz 10 različnih gnezd. Opazovanje je bilo razdeljeno na dve ponovitvi. Tekom laktacije smo pujske označili in opazovali njihov položaj na vimenu svinje. Proučevali smo stabilnost sesnega reda, prirast pujskov, pojav navzkrižnega sesanja ter stopnjo smrtnosti. V raziskavi smo ugotovili, da se je sesni red v skupinskih boksih in pri pujskih, ki so sesali navzkrižno, vzpostavil po prvem tednu starosti, ko je verjetnost sesanja na istem sesku znašala 50-60 %, medtem ko je bil sesni red v individualnih boksih vzpostavljen do 3. dneva laktacije, ko je stabilnost sesnega reda znašala 0,40-0,50 in se na podobni ravni ohranjala do konca laktacije. Prirast je bil tekom laktacije primerljiv med skupinami. V prvem tednu je pri vseh skupinah naraščal, pri čemer so v zaključku prvega tedna pujski iz individualne reje kazali boljše rastne razmere, ampak razlike v večini niso statistično značilne (p ≥ 0,05). Tekom laktacije je poginilo 14 pujskov (t.j. 11 % smrtnost), pri čemer je bil pogin prisoten zgolj v skupinskih boksih. The aim of this study was to research the properties of the suckling behaviour in the group farrowing systems and compare the results with conventional ones, i.e. individual farrowing systems. A total of 129 piglets from 10 different litter were included in the study. The observations were divided into two repetitions. During lactation, piglets were marked and its position on the udder of the sows was determined. The stability of suckling order, piglet´s weight gain, the occurrence of cross-sucking, and the mortality was studied. The suckling order in the group farrowing system, as well as by the cross-sucklers, was established after the first week of age, when the probability of suckling on the teat was 50-60 %, while the suckling order in the individual system was established until the 3rd day of lactation, when the stability of the suckling order was 0.40-0.50 and as such maintained until the end of the lactation period. The weight gain was comparable between groups during lactation. In the first week, the weight gain was in general increased, however better growth conditions of piglets were showed in individual farrowing systems at the end of the first week - the differences were not statistically significant (p ≥ 0.05). During the lactation period 11% mortality (14 piglets in total) of the piglets was recorded, whereby the piglets’ loss was present only in the group farrowing system. prašič laktacija sesno obnašanje navzkrižno sesanje prirast individualna reja skupinska reja pig lactation suckling behaviour cross-suckling weight gain individual housing group housing true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-20 11:05:10 2017-10-03 10:33:13 2022-08-01 15:30:42 2019-07-11 16:51:54 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:YASVLEF8 VS_Mesaric_Alja_2017.pdf VS_Mesaric_Alja_2017.pdf 1 E887A47853BB01BBE4026142DF671F9E 1b37fcda076bc0d9e33c8e1f568d2f2c2fe28898cbbdcebb9fa7663b14a1809b 666bbc05-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/5ff638e0-0c98-4625-92ce-4ca5448492cc https://dk.um.si/Dokument.php?lang=slv&id=119281 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
