Abstract :

   Bulk milk somatic cell count(SCC), somatic cell score(SCS) and total bacterial count (TBC)are the most important milk health parameters.the aim of this study was to investigate SCC,SCS and TBC in a dairy herd of Khuzestan province.a general linear model(GLM) procedure was used for analyzing of data.the result showed effects of year and month are significant on variation of SCC,SCS, and TBC.the highest and lowest SCC and SCS were observed in September and January respectively and the highest and lowest TBC was observed in January and May.the result showed SCC,SCS and TBC increased significantly over time,and it implies the quality of milk decreased in mentioned years.it seems to control this upward movement applying new policies is necessary.in addition,high total bacterial count showed pasteurization is necessary to produce more healthy milk.
