| Popis: | In the present study, the relationship between total bulk milk somatic cell counts (BMSCC), differential BMSCC (macrophage, lymphocyte, and polymorphonuclear leukocytes), and antioxidant enzymes was investigated. Forty-three samples of bulk milk were selected randomly from eight dairy farms in the region of Sfax (Tunisia) in winter, from November 2005 to February 2006. Bulk milk samples were analyzed for antioxidant enzymes such as catalase, SOD and GSHPx activity and differential SCC. After that, milks were allotted according to their total SCC to: group 1, bulk milk with SCC below 1000x10(3) ml(-1); group 2, bulk milk with SCC from 1000x10(3) to 1500x10(3) ml(-1); group 3, bulk milk with SCC above 1500x10(3) ml(-1). BMSCC levels ranged from 400x10(3) to nearly 4000x10(3) ml(-1). Lymphocytes were the predominant cell type in all groups, but their proportion declined with the total BMSCC. Catalase and GSHPx activities were found to be significantly (P |
