Abstract
In the present study, a total of 547 half milk samples were collected from 274 dairy goats to perform somatic cell counts (SCC) and California mastitis test (CMT). Milk smear was stained with Pyronin Y-Methyl Green stain were classified into either epithelial or blood cells, etc. Of the 547 halves the percentage of CMT negative milk samples were 86%. Among these, 58.2% were CMT negative with SCC<500,000/ml, while 27.8% were CMT negative with SCC>500,000 ml. As expected, CMT score increased with the increase of SCC. The number of epithelial cells decreased with the increasing number of somatic cells, while the opposite was observed with the number of blood cells. These results indicate that the critical point in milk quality & CMT should be considered on the false (pseudo-SC) SCC in dairy goat.
