AbstractThe present study was carried out in Al-Diwaniyah city and its different districts, which includes (city center, Afak district and their regions, Al-Hamza district and their regions, Al-Shamiya district and their regions, Al-Daghra regions and its villages) during a period November 2009 to July 2010. A total of samples used in this study were 120 raw milk samples collected includes 60 samples for each species for (sheep and goats) for two different season of year (Winter and Summer), first start from (beginning November 2009 to end of the January 2010),and the second start from (beginning May to July 2010) The results of this study revealed the rising the averages of microbes contaminated raw milk samples in each species of animals included in this study where raw milk samples for sheep recorded (0.16×106 CFU/ml) and goats (0.13×106 CFU/ml). The highest averages of total Coliform bacterial count were found in raw milk samples of sheep and goats (0.15×106 CFU/ml). While averages of Staphylococcus aureas were high in raw milk samples of sheep (0.20×106 CFU/ml) and less in raw milk samples of goats (0.14×106 CFU/ml). While the average of Streptococcus spp. Were (0.30×106 CFU/ml) and (0.27×106 CFU/ml) for sheep and goats respectively. Seasons of the year had effect on average of total bacterial count studied for each samples of raw milk for all species of animals included in this study. Where shown rising averages of all microbes numbers during summer period while there are decreasing in average of microbes during winter period which variances significantly (P≤0.05).
