20.500.12556/DKUM-54773 Fenotipske lastnosti potomcev križanja štajerske in pritlikave vijandotske kokoši v zgodnjem stadiju razvoja Phenotypic characteristics of hybrids between Styrian and Wyandotte dwarf chicken breeds in early stage of development V začetku leta 2015 smo križali štajersko kokoš s pritlikavo vijandotsko kokošjo na kmetiji Fijavž v Vitanju. Opazovali smo lastnosti, ki so se pojavljale pri potomcih križanja v zgodnjem stadiju razvoja, od prvega dne izvalitve piščancev do starosti enega meseca. Ker smo pri križanju uporabili dve pasmi z osebki različnih barv, smo dobili barvno zelo različne piščance. V križanje smo vključili štajerske kokoši v jerebičasti barvi in kokoši pritlikave vijandotske kokoši v srebrni, zlati ter rumeni barvi. Oblikovali smo pet skupin s po štirimi kokošmi in petelinom druge pasme. Prve štiri skupine so tako imele po štiri 'štajerke' in 'vijandotskega' petelina, peta skupina pa 'štajerskega petelina' in kokoši pritlikave vijandotske pasme. Pri piščancih smo po izvalitvi opazovali barvo puha in nog ter določili telesno maso. To smo ponovili pri en mesec starih piščancih. Ugotovili smo, da se barva perja, vizualni izgled kokoši, pozna operjenost petelinčkov in greben v večji meri dedujejo po vijandotskih kokoših, velikost, barva nog, priuhek, rep in čopek pa po štajerski kokoši. At the beginning of the year 2015, on the farm Fijavž near Vitanje, we crossed the Styria chicken breed with the Dwarf-Wyandotte breed. We studied the features which occur on hybrid progenies on the day of chickens’ hatching until they were one month old. As we recombined two breeds characterised with very different colours, we obtained phenotypically very heterogeneous progenies regarding their colours. We recombined the ‘partridge’ coloured Styrian chicken with Dwarf-Wyandotte chicken in silver, gold, and yellow colour. We established five mating groups, each with four female chickens belonging to one breed and a rooster belonging to the other breed. The first four mating groups involved four Styrian female chickens and a Wyandotte rooster in each, whereas the fifth mating group involved the Styrian rooster and Dwarf-Wyandotte female chickens. After hatching we studied the chickens’ down colour, leg colour and weight. The same was repeated on one month old chickens. We found out that the feather colour, visual appearance of chickens, late feathering of little roosters and ridge are mostly inherited from the Wyandotte breed. The size, leg colour, down, tail, and tuft are inherited to a greater extent from the Styrian breed. pasme kokoši barva perja križanje greben masa piščancev chicken breeds feather colour interbreeding comb live weight true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-09-11 12:50:01 2015-09-28 08:11:37 2022-06-06 03:07:00 2021-05-12 03:33:35 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:MIUUM5UA UN_Fijavz_Uros_2015.pdf UN_Fijavz_Uros_2015.pdf 1 15ED4FBBB332C0C6CC45C30F1FF2C9F1 a467b270ce63a00708a4415c506fb6c47f4ab3e8b7bf9d4ad8ea2f2b3e4b7fdf c8a4bd0f-7c07-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=80976 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
