20.500.12556/DKUM-47843 UGOTAVLJANJE KONDICIJE KRAV MOLZNIC NA OSNOVI MERITEV Z ULTRAZVOKOM DETERMINATION OF THE CONDITION OF DAIRY COWS ON THE BASIS OF ULTRASOUND MESURMENTS Cilj proučevanja je bila uporaba ultrazvoka za ugotavljanje kondicije (BCS) krav molznic. Vključevala je 41 krav molznic, od tega jih je bilo 10 črno-bele pasme, 13 lisaste pasme in 18 križank. Primerjali smo kondicijo krav, in sicer na osnovi subjektivne ocene dveh izkušenih ocenjevalcev in ocen, ki temeljijo na ultrazvoku debeline maščobnega tkiva. Ugotovili smo, da ni statističnih razlik, razen razlik, povezanih s pasmo. Medtem ko se BCS lisaste pasme, ki znaša 3,71 ± 0,52, ne razlikuje od kondicije križank, ki znaša 3,76 ± 0,36, se pa razlikuje od kondicije črno-bele pasme, ki znaša 3,25 ± 0,39. The study was investigating the use of ultrasound to determine the body condition score (BCS) of dairy cows. It included 41 dairy cows, of which 10 were Holstein Friesians, 13 Simmentals and 18 crossbreeds. We compared the BCS of the cows based on the subjective assessments of two experienced assessors and evaluations based on the ultrasound of the fat tissue thickness. We discovered that there are no statistically significant differences except for the breed related differences. While the BCS of Simmentals, which amounts to 3.71 ± 0.52 does not differ from the condition of the crossbreeds, which amounts to 3.76 ± 0.36, it differs from the condition of the Holstein Friesian, which is 3.25 ± 0.39. krave molznice kondicija ultrazvok dairy cows condition ultrasound true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-04-15 12:51:54 2015-05-04 12:55:04 2022-05-23 03:06:36 2021-05-08 03:17:39 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:I1H5SAYY VS_Mocnik_Urska_2015.pdf VS_Mocnik_Urska_2015.pdf 1 57DA906ADAAEAE8B944CF55B3129D079 cc8f8211bc3e2e25cee9ea3824b9620bfbf779992004fca52ba5f926696428fd 9aa46f50-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=71287 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
