Body Temperature and Milk SCC DeterminationRectal temperatures were measured at 0, 4, 8, 12, 24, 36, 48, 72, and 96 h to assess the febrile response. The SCC in milk were determined at 0, 12, 24, 36, 48, 72, and 96 h relative to challenge. Prior to full milk withdrawal, foremilk samples were collected into 48-mL collection tubes that contained bronopol as a preservative. Samples were then shipped overnight to Belleview Lab Southeast Milk Inc. (Belleview, FL) for determination of SCC by flow cytometry. Somatic cell counts were log-transformed for statistical analysis and reported as log10 of SCC.
