摘要

The incidence of clinical mastitis in dairy goats is low at less than 5% per lactation (Bergonier et al., 2003), however, there is a recognised need in the industry for a simple, practical and reliable means for the detection of sub-clinical mastitis.In goats, conversely to cows, somatic cell counts (SCC) are not a reliable indicator of infection. Bacteriological cultures can be used to identify glands with sub-clinical infection, but this approach involves specialized sampling. Serum amyloid A (SAA) is a family of acute phase proteins that is produced in response to infection and inflammation. Levels of this protein in milk have been proposed as a sensitive indicator of mastitis infection in the dairy cow (Akerstedt et al, 2007; Jacobsen et al, 2005; O'Mahony et al, 2006; Weber et al, 2006) and in dairy sheep (Winter et al, 2005). Conversely, one report in the literature suggests that this relationship does not hold true in dairy goats (Winter et al., 2005).
