20.500.12556/DKUM-36758 Mlečnost krav lisaste pasme na kmetiji z omejenimi dejavniki okolja Milk yield of simmental cows on the farm with limited environment factors V raziskavi smo analizirali nekatere povprečne letne parametre mlečnosti krav lisaste pasme v standardni laktaciji na kmetiji z omejenimi dejavniki okolja. To pomeni, da ima ta kmetija zaradi različnih okoljskih dejavnikov (relief) oteženo pridelavo kvalitetne osnovne krme. V raziskavi smo uporabili letna povprečja količine mleka v standardni laktaciji, vsebnosti beljakovin v mleku ter vsebnosti maščob v mleku za 16-letno obdobje od leta 1995 do 2010. Podatke kmetije smo primerjali še z enako strukturo podatkov kmetij na območju zavoda Murska Sobota in s podatki kmetij na območju Slovenije. S statistično analizo smo ugotovili, da je bila povprečna letna rast mlečnosti na obravnavani kmetiji največja (127,1 kg) v primerjavi s povprečno letno rastjo mlečnosti kmetij na območju zavoda Murska Sobota (77,5 kg) in kmetij na območju Slovenije (82,8 kg). Povprečna mlečnost kmetije je leta 2010 znašala 4483 kg, na kmetijah zavoda Murska Sobota 4960 kg in na kmetijah celotne Slovenije 5031 kg. Vsebnost maščob se v 16 letih ni bistveno spremenila. V letu 2010 je znašala vsebnost maščob na kmetiji 3,90 %. Dvig vsebnosti beljakovin v obdobju 16 let je bil najbolj opazen na kmetiji (z 2,90 % v letu 1995 na 3,29 % v letu 2010). Our graduation thesis was aimed at analyzing some average yearly parameters of milk yield of Simmental cows in standard lactation on the farm in a less favoured area (LFA). This means that quality forage production on this farm is difficult because of different natural handicaps (e.g. relief). In this study we used data on annual average quantity of milk in standard lactation, protein content as well as the content of fats in milk for the 16-year period from 1995 to 2010. We compared the data of this farm with the data in the area of Murska Sobota Agricultural Institute, as well as with the data of all other farms in Slovenia. Our statistical analysis showed that the average yearly growth of milk yield on the examined farms was the highest (127.1 kg) in comparison to the average yearly growth of milk yield on farms in the area of Murska Sobota Agricultural Institute (77.5 kg) and on all other farms in Slovenia (82.8 kg). The average milk yield of this farm in 2010 was 4483 kg, on farms in the area of Murska Sobota Agricultural Institute it was 4 960 kg and on other farms in Slovenia it reached 5 031 kg. The fat content in the milk of the examined farm was not significantly changed in 16 years. In 2010 the fat content was 3.90 %. In the examined period the highest increase on this farm was observed in protein content (from 2.90 % in 1995 to 3.29 % in 2010). mlečnost / lisasta pasma / kontrola mleka / rejski program milk yield / Simmental breed / milk recording / breeding program true true false Slovenski jezik Angleški jezik Diplomsko delo 2012-06-26 13:52:14 2012-07-26 13:24:43 2022-04-21 14:26:59 2023-12-31 03:21:13 2012 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:CF5GCW0D VS_Prelec_Andrej_2012.pdf VS_Prelec_Andrej_2012.pdf 1 5B1C1C3370B747AFCD9DF2EEF4AD663B 03993763062c4b498ca787647802a03ee6fdd636934a761833aadd004556262e 1fc15e8d-7c08-11eb-bb7a-00155d0001ca 20.500.12556/dkum/6a965680-21da-4e65-8e1a-72cb65c683fb https://dk.um.si/Dokument.php?lang=slv&id=48084 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
