MASTITIS IN LOW SOMATIC CELL COUNT DAIRY HERDS – pre-liminary results from a postal questionnaire survey
A questionnaire survey of dairy farmers with low bulk tank milk somatic cell counts (BTMSCC) was carried out to assess the level of mastitis and to quantify risk factors for mastitis. Questionnaires were sent to 3009 producers with an average BTMSCC in 1997 of less than 100,000 cells/ml. One thousand eight hundred thirty nine replies were received, a 61% response rate.

A dynamic and stochastic simulation model, SimHerd, was used to study the effects of mastitis in a herd with 150 cows. Results given the initial...
متن کاملPrevalence, somatic cell count and etiology of bovine mastitis in Cuban herds from Mayabeque province using hand and machine milking
Few studies have been developed to evaluate the differences of bovine mastitis situation between hand and machine milking under the American tropic conditions. Twenty dairy herds were studied, 11 using hand milking (HM) and 9 machine milking (MM), from «San José de las Lajas» municipality, Mayabeque province. Between May 2009 and March 2012, samples from 182 cows (113 MM and 69 HM) were obtaine...
