Abstract

Th e “ cow hygiene score” system is a management tool for assessment of cow’ s body hygiene and cleaning of the barn. In this study, the correlation between body hygiene scores and intramammary infections (IMI), California mastitis test (CMT) and somatic cell count (SCC) were evaluated in two diff erent seasons. Hygiene scoring of 1096 dairy cows in 4 herds was performed on fi ve body areas including: udder, rear legs, fl anks and upper legs, abdomen, and tail head. Aft er doing CMT, milk samples were taken from quarters with score 2 or more for microbiological culture. SCC data were taken in two consecutive months. Th e results of this study showed no signifi cant diff erences between the median of all hygiene scores except for tail head that were signifi cantly greater in high than low rainy seasons (p < 0. 05). Th ere was no signifi cant correlation between hygiene scores and the chance of positive bacterial culture (p > 0. 05), but a statistically signifi cant relationship was found between udder hygiene score and isolation of environmental bacteria (p < 0. 05). Th ere were no statistically signifi cant diff erences between SCC or CMT and hygiene scores of all parts of the body and similarly between teat cleanliness score aft er premilking preparation and SCC in two consecutive months (p > 0. 05). Finally, it seems that udder hygiene scoring is an useful tool for predicting of intramammary infections caused by environmental bacteria.
