20.500.12556/DKUM-39678 POVEZAVA MED POPORODNIM PREMOROM IN LASTNOSTMI MLEČNOSTI PRI LISASTI PASMI Relationship between calving interval and milk yield in Simmental breed Cilj raziskave je bil ugotoviti vpliv poporodnega premora in zaporedne laktacije na lastnosti mlečnosti (količina mleka, vsebnost maščob in beljakovin) v celotni in standardni laktaciji. Analizirali smo 2454 krav lisaste pasme in njenih križank z območja Pomurja v obdobju od leta 2006 do 2010. V raziskavo smo zajeli 9 zaporednih laktacij, poporodni premor pa smo razdelili na štiri razrede (kot meje smo vzeli kvartile). Vse podatke smo pridobili preko portala CPZ govedo na Kmetijskem inštitutu Slovenije. Vpliv zaporedne laktacije in razredov poporodnega premora na preučevane lastnosti smo izračunali z analizo variance, razlike med obravnavanji pa smo preverili s Tukey-evim testom pri 95 % tveganju. Ugotovili smo, da poporodni premor in zaporedna laktacija statistično značilno vplivata (P≤0,0001) na proučevane lastnosti mlečnosti. Zaporedna laktacija nima značilnega vpliva (P=0,3967) na poporodni premor. Rezultati mlečnosti iz naše raziskave so skladni z rejskimi cilji za lisasto pasmo. The aim of this research was to find out the influence of calving interval and consecutive lactation on the characteristics of milk yield (the amount of milk, the content of fat and proteins) in the whole and standard lactation. A total of 2454 cows of Simmental breed and their interbreeds were analysed from Pomurje region from 2006 to 2010. There were 9 consecutive lactations taken into research, calving interval was divided into four classes (we took quartiles for limits). All data were collected from the portal CPZ cattle on the Agricultural Institute of Slovenia. The influence of consecutive lactation and classes of calving interval on the examined characteristics was calculated with analysis of variance, the differences between the proceedings were tested by Tukey' test. The calving interval and consecutive lactation had significant effect (P≤0.0001) on milk characteristics. On the contrary, consecutive lactation had no effect (P=0.3967) on calving interval. The results of milk yield from our research are consistent to the goals of breeders of Simmental cattle. poporodni premor zaporedna laktacija mlečnost vsebnost beljakovin vsebnost maščob calving interval consecutive lactation milk yield milk proteins milk fat true true false Slovenski jezik Angleški jezik Diplomsko delo 2013-02-15 09:22:37 2013-04-02 14:35:05 2022-05-12 23:08:18 2021-04-22 03:26:42 2013 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:JJ9AORQZ VS_Borovic_Tadeja_2013.pdf VS_Borovic_Tadeja_2013.pdf 1 8325BB959B6A35C9D41576C1859C462A aa91a86788449b3f4049b570d222208851f86ac46e5a3678ba7c31120aab7566 2ed9d9bc-7c09-11eb-bb7a-00155d0001ca 20.500.12556/dkum/cf2d4ede-0f52-4565-b630-91ba4a4f8903 https://dk.um.si/Dokument.php?lang=slv&id=53793 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
