Variation in Swedish bovine raw milk from 1995 to 2020 : focus on composition and properties
The composition and properties of Swedish bovine raw milk are influenced by several factors which have varied over the last 25 years. Factors influencing milk quality include: bovine breed, stage of lactation, type of feed, and climate. The overall aim of this thesis was to investigate the variation...

| description | The composition and properties of Swedish bovine raw milk are influenced by several factors which have varied over the last 25 years. Factors influencing milk quality include: bovine breed, stage of lactation, type of feed, and climate. The overall aim of this thesis was to investigate the variation of Swedish bovine raw milk quality over the last 25 years. Changes on Swedish dairy farms and dairies were also investigated. This thesis is a literature review. Searches in online databases were conducted for primary research. Scientific studies, book chapters, Swedish databases, websites, and personal communications were also used to collect information. The literature review revealed that over the last 25 years the protein content has increased from 3.34% to 3.50% while the fat content has been stable around 4.2%. Over time, variations in lactose, calcium, citric acid, somatic cell count, and pH were small. Sweden has gone from several small dairy farms to fewer farms with larger herd size. |

Den svenska obehandlade mjölkens kvalité påverkas av flera olika faktorer och har varierat de senaste årtiondena. Faktorer som påverkar mjölkens kvalité är exempelvis ras, laktationsstadie, foder samt klimatförhållanden. Det övergripande syftet med uppsatsen var att ta reda på vilka variationer som har skett i den svenska mjölkråvaran de senaste årtiondena. Förändringar på svenska mjölkgårdar och mejerier studerades också. Denna uppsats är en litteraturstudie. Internationella databaser, svenska databaser, vetenskapliga artiklar, böcker och webbsidor användes samt en intervju genomfördes för att söka och samla information. Protein och fetthalten visade sig ha signifikanta variationer i mjölken både mellan säsong och årtionden. Proteinhalten ökade från 3.34% till 3.50% medan fetthalten har varit stabil på 4.2%. Över tid har mjölkens innehåll av laktos, kalcium, citronsyra, somatiska celler och pH-värdet endast visat på mindre variationer. Sverige har gått från att ha många små mjölkgårdar till färre antal gårdar med större besättningar. SLU/Department of Molecular Sciences 2020 M2 eng swe https://stud.epsilon.slu.se/16187/ |
