Abstract: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.

Title:DETERMINATION OF THE CONDITION OF DAIRY COWS ON THE BASIS OF ULTRASOUND MESURMENTS
Abstract: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.
