dc.description.abstract Somatic cell count (SCC) is an indicator of the health and cleanliness of dairy cattle and is directly related to incidence of mastitis. The effects of cow breed (n = 10/breed, Holstein & Jersey) on milk yield, milk quality, SCC, bacterial cultures, and hygiene scores were compared over a 6-wk period. Milk Samples with a SCC >350,000 cells/ml were cultured. Holstein cows produced significantly more milk than Jerseys (P = 0.0181) and had a greater conductivity (P = 0.0005). SCC measurements were not significantly different. Jerseys had lower hygiene scores indicating that they were cleaner than Holsteins in their udder and flank area. There were no significant differences in leg scores by breed or bacterial species cultured. The results insinuate that Jerseys are cleaner overall, and that conductivity is related to milk yield en_US
