Abstract
Cilj ovog diplomskog rada bio je utvrditi sadržaj i sastav masnih kiselina u mlijeku krava pasmine Jersey kao i utjecaj sezonskim promjenama u hranidbi na iste. Prikupljeni su skupni uzorci mlijeka iz laktofriza tijekom godine dana. Tijekom laktacije krave su dobivale tri obroka: stajski - TMR obrok baziran na sjenaži lucerne, prijelazni - krave su boravile pola dana na ispaši i pola dana u staji te pašni - krave su između jutarnje i večernje mužnje boravile na ispaši. Prosječan udio mliječne masti u Jersey mlijeku iznosio je 5,74%, udio proteina 3,92%, a udio bezmasne suhe tvari 9,39%. U ovom istraživanju je utvrđen značajan utjecaj sezonskih promjena u hranidbi na sastav masnih kiselina u mlijeku krava Jersey pasmine. Tijekom pašne sezone u mlijeku je utvrđen značajno (p<0,05) manji udio palmitinske kiseline kao i manju ukupni udio zasićenih masnih kiselina u odnosu na stajsku sezonu. Ujedno, pašno mlijeko imalo je veći udio jednostruko i višestruko nezasićenih masnih kiselina.
Abstract (english)
The aim of this study was to determine the composition of fatty acids in Jersey milk and possible variations due to seasonal variations in diet. Bulk tank milk samples were collected once a month for 12 months. During lactation, cows received three rations: farm – TMR based on alfalfa haylage, transition – half a day feed with TMR and half a day grazed on pasture, grazing –grazed during all day on pasture. Average amount of milk fat in analysed milk samples was 5.74%, protein 3.92% and non-fat milk dry matter 9.39%. In the present study was found significant (P<0.05) effect of seasonal changes in cows ration on fatty acid profile of Jersey milk. During grazing season was found lower (p<0.05) C16:0 and total saturated fatty acid content. In addition, grazing milk had higher content of monounsaturated and polyunsaturated fatty acids.
