20.500.12556/DKUM-46769 DEBELINA IN DOLŽINA VLAKEN OVČJEGA RUNA OPLEMENJENE JEZERSKO-SOLČAVSKE PASME OVAC NA RAZLIČNIH MESTIH TELESA PRI RAZLIČNI STAROSTI FLEECE LENGTH AND FIBRE DIAMETER OF THE IMPROVED JEZERSKO-SOLČAVA SHEEP AT DIFFERENT BODY SITES AND DIFFERENT AGE Cilj diplomskega dela je spoznati karakteristike runa oplemenjene jezersko-solčavske pasme ovac, ki je v Sloveniji najštevilčnejša in katere runo še ni dodobra raziskano. Predstavljeni so rezultati analiz runa, odvzetih na različnih mestih telesa in pri različni starosti ovac. Merili smo dolžino in debelino volnenih vlaken. Dolžina vlaken je nihala v razponu med 21 mm in 299 mm, debelina pa med 24,5 µm in 65,3 µm. Najdaljša vlakna so na plečetu (187,3 mm ± 32,8 mm), najkrajša pa na trebuhu (76,7 mm ± 29,6 mm). Tanka in sorazmerno dolga so na vratu (38,7 µm ± 5,8 µm), zato je tam runo boljše kvalitete za potrebe predelave. Ugotovili smo, da so vlakna pri starejših ovcah krajša kot pri mlajših, kar pomeni, da s starostjo ovac vlakna počasneje rastejo. Runo je postalo bolj grobo zaradi križanja oplemenjene jezersko-solčavske pasme z romanovsko. The purpose of this work is to investigate the fleece of the improved Jezersko-solčava sheep, which is predominant in Slovenia and the fleece of which has not yet been thoroughly researched. Analysis results of the fleece, taken from different body parts of sheep of various ages are presented. We measured the length and the diameter of wool fibers. The fibre length variated from 21 mm to 299 mm, while the diameter from 24.5 µm to 65.3 µm. The longest fibers are located on the shoulders (187.3 mm ± 32.8 mm), the shortest on the abdomen (76.7 mm ± 29.6 mm). Thin and relatively long are the fibers on the neck (38.7 µm ± 5.8 µm), therefore the fleece from the neck is better quality for wool production. The results indicate, that the fibers from older sheep is shorter than those from younger sheep, which implies that fiber growth rate decreases with age. Fleece has become rougher because of cross-breeding of the improved Jezersko-solčava with Romanov sheep. debelina in dolžina vlaken runo oplemenjena jezersko-solčavska pasma starost diameter and length of fibers fleece improved Jezersko-solčava sheep age true true false Slovenski jezik Angleški jezik Diplomsko delo 2014-11-04 18:38:17 2014-12-01 09:05:34 2022-05-18 03:08:09 2021-05-05 03:24:19 2014 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:UPM9ZZVO VS_Sevcnikar_Gasper_2014.pdf VS_Sevcnikar_Gasper_2014.pdf 1 EC820AE168D79F9C0AB5BE8E03198655 3d20ba1be2388c71be6164f33c3d4bd754efccb013de8ee8204735d6329fd772 68f99ebb-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=68702 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
