Abstract
The main objective of this study was to analyze the effect of bacterial content (CFU) and somatic cell count (SCC) in milk quality in sheep (Ovis aries) farms according to the existing standards for fresh milk quality in Kosovo. A total of 2256 milk test day records from 379 Bardhoka (BAR), Sharri sheep (SHA), Kosovo sheep (KOS) and Balusha (BAL) ewes in eight herds across the country were collected and analyzed through a period April-October 2010. The general linear model and Duncan’s test were used to analyze the effect of different variables on presence of CFU and SCC in fresh milk. The effect of all variables was considered as a fixed. The overall results show that farm (P 0422), respectively, had a significant effect on presence of SCC. For CFU farm (P 0422) and breed (P 1211.17 to 6425.76 CFU/mL and 846.07 to 2043.15 SCC/mL milk, respectively. Although the rate of fresh milk contamination with SCC tends to be relatively low compare with CFU, by all means both variables should not be underestimated bearing in mind that a high rate of them on fresh milk are negatively correlated with farmer’s profit, consumer food safety and overall animal health.

The main objective of this research was to study the impact of bacterial content (CFU/mL) and somatic cells (SCC/mL) in fresh milk quality in some sheep farms based on existing standards and derive valuable recommendations for the sheep dairy industry in Kosovo
Summary
One of the main items in human nutrition, where its biological and chemical content, represents a suitable environment for the development of microorganisms, as well. (Streptococcus uberis, Streptococcus agalactiae, Streptococcus dysgalactie); Coliphorm group; Pseudomonas (Cepacia burkholderia, Pseudomonas aeruginosae). Besides these bacteria within the sheep can be found mushrooms and some mycoplasma species, which trigger sub-clinical mastitis, as well. Knowing that SCC presents heath udder and body indicator, their growth in milk is indication that we are dealing with unsanitary milk and weakened the animal health. This is the reason that SCC represents one of the parameters for determining the quality of milk. The large number of SCC induces changes in milk quality and its loss in pro-
