摘要: Sheep herds are a significant capital of dairy industry in Greece, but as farming becomes more complex and intense the need to provide assistance producers on milk quality is critical. In this study, raw produced sheep farms NE Greece was surveyed role various factors explored. total, 21 ewe’s from regions Xanthi Evros, north-eastern were monitored. Milk samples sampled after morning milking every 15 days throughout period (March–June). For questionnaire also filled by personal interview with owners order collect information about herd characteristics, health status, handling practices etc. From each farm, air for microbiological analysis. examined chemical components: fat content, protein, lactose, non-fat dry matter (NFDM) somatic cells count (SCC). Microbiological examination involved estimation Total Bacterial Counts (TBC), coliform (CC), Staphylococcus aureus, Streptococcus sp., preliminary incubation (PIC). The possible correlation among different bacterial species their interaction SCC components considered. It whether farm management could influence hygiene milk. Our results show that an average TBCs 5.48 log cfu/ml, SCC: 6.05 log cells/ml, CC: 4.49 log cfu/ml, S. aureus: 3.94 log cfu/ml, sp.: 4.95 log cfu/ml PIC: 5.7 log cfu/ml. mean fat, lactose NFDM 6.17%, 5.28%, 4.73% 10.95% respectively. study revealed positive between TBC PIC (0.825), while marginally correlated protein NFDM. No statistically correlations observed any species. Herd size had considerable
