The study was carried out on small-holder camel farms in Egypt. Among the CMT-positive samples, the incidences of CMT (+), CMT (++) and CMT (+++) scores were 26.7, 12.9 and 9.9%, respectively. The mean SCC values of CMT-positive and CMT-negative milk samples were 69 x 10³+or-7.32 and 304 x 10³+or-2.52, respectively. The results confirmed the high correlation between the CMT and SCC in both CMT-positive and CMT-negative samples. The most common causes of subclinical mastitis found in the milk samples were coagulase positive staphylococci (CPS), coagulase negative staphylococci (CNS) and coliforms. Moreover, raw camel milk had high total aerobic, coliform, total yeast and mould and CPS counts. The analysis of variance (ANOVA) confirmed the significant differences (P<0.05) in the means of fat percentage, protein percentage, urea percentage, total solids percentage, solids not fat percentage, SCC, total bacterial count, staphylococci count, coliform count and yeast count between normal and mastitic milk samples. It was concluded that fresh camel milk could be considered a perfect and highly nutritional food if produced under acceptable hygienic measures (free from any human health hazards due to subclinical mastitis or post-milking contamination). 收起
