Abstract

Strojna mužnja uvedena je kako bi se olakšala i ubrzala mužnja, smanjio broj muzača te da bi se dobio higijenski ispravan proizvod. Cilj istraživanja je bio utvrditi razliku u broju subkliničkih upala vimena i broja somatskih stanica ručno i strojno muženih ovaca te izolirati najčešće uzočnike upala. U istraživanju su ispitani uzorci mlijeka izvorne hrvatske pasmine paške ovce uzgajane na otoku Pagu. Ispitano je 150 uzoraka, od kojih je 100 uzoraka ručno i 50 uzoraka strojno muženih paških ovaca. Od 150 uzoraka, u njih 17 je utvrđena prisutnost nekog od uzročnika subkliničke upale vimena, odnosno u 11,3 %. U prvom stadu, pozitivno je bilo 6 od 50 (12 %), u drugom stadu 4 od 50 (8 %), te u trećem stadu, gdje se provodi strojna mužnja ovaca, 7 od 50 (14 %) uzoraka. Najčešći uzročnik u ovom istraživanju bio je Staphylococcus aureus (u 70% slučajeva).

Abstract (english)

Machine milking has been introduced to facilitate and accelerate milking, reduce labor and to increase hygienically quality of product. The aim of this study was to determine a difference in number of subclinical inflammation of udder and somatic cells count and isolate most common microorganism that causes inflammation. Milk samples of original Croatian sheep breed farmed on island Pag, were tested. 150 samples were tested, 100 samples of hand milked and 50 samples of machine milked Paška sheep. 17 of 150 (11,3 %) were positive on some of microorganism known to cause subclinical inflammation. In first herd 6 out of 50 (12 %) samples were positive, in second 4 out of 50 (8 %) and in third herd, where sheep are machine milked, 7 out of 50 (14 %) were positive on pathogenic microorganism. The most common pathogenic microorganism was bacteria Staphylococcus aureus (in 70 % cases).
