| Sumario: | The aim of the present thesis is to describe the background and specifically investigate the effect of a single prolonged milking interval on cell traffic in the bovine mammary gland and on milk composition. The literature study of the thesis is slightly broader than this and
includes also other facts about the bovine mammary gland of interest and relevancy to the narrower subject of the research project. The reason behind performing the research project and writing the thesis is originating in questions raised in relation to practical observations in dairy herds. It has been noticed that after a technical stop in an automated milking system resulting in a prolonged milking interval (PMI), many cows show a short lasting increase in milk somatic cell count (SCC). This can influence the herd milk SCC and may result in reduced payment of the milk due to rules based on that increased milk SCC is associated with lowered milk quality. It is, thus, of economical importance for the producer. By
studying the cell traffic in the udder when the SCC is increased but under non-mastitic conditions it was expected that also new information could be gained about the cell traffic in the normal udder which has been poorly studied. The mechanisms behind these SCC peaks and whether they influence milk quality are not clarified. |
