Determination of Quality of Raw Milk Collected from Atatürk University Agriculture Faculty Pilot Dairy Plant

In this study, the quality of produced products have a great importance. for this purpose, raw milk samples is obtained from atatürk university dairy plant for every four seasons separately (summer, autumn, winter, spring) to protect human health and produce quality products. physical and chemical properties (dry matter, fat, ash, protein, specific gravity, acidity and ph) of raw milk samples and microbiological (somatic cell count, total aerobic mesophilic bacteria (tamb), mould, yeast, coliform bacteria and staphylococcus aureus (s. aureus)) properties were investigated. dry matter, ash (p<0.05) and fat (p<0.01) values of raw milk samples were affected significantly by dairy farm, meanwhile protein, specific gravity, ph and acidity values were not affected (p>0.05). seasons had a significant effect on dry matter, protein, fat (p<0.05), ash and ph (p<0.01) values of raw milk samples. but, seasons did not have a significant effect on only specific gravity and acidity values (p>0.05). tamb, yeast, mould counts indicated significantly changes based on dairy farms and seasons. on the other hand, coliform bacteria was not affected (p>0.05) by dairy farms and seasons. s. aureus counts were affected statistically by only seasons (p<0.01).
