Résumé

This work constitutes a preliminary step in exploring the relationship between udder health of dairy cows and hygienic conditions, technical and technological processes in the farming type aboveground are prevalent in the Sahel of Tunisia. The sample of farmers surveyed is located in the region of Mahdia, basin and milk largest producer of milk nationally. Was used in this study to the analysis of farming conditions, among other conditions of milking, and evaluation of the infection status of milk in the three diagnostic methods usually adopted CMT, ICC and CRH. The study parameters of dairy cattle in the region of Mahdia show characteristics for small cattle farms aboveground. Half of the farmers have herds of cows less than 6 on average. Most farms have stanchions and a diet based mainly on concentrate. All these features have led to frequent cases of mastitis in cattle repeatedly visited an average of about 11 times a year. The medical diagnosis of breast milk cows gives an idea about the current state of health of cows to mastitis controlled both clinical and subclinical. It was noted that 37% of neighborhoods tested are infected, the average individual somatic cells is 560000 cells/mL, 27% of farms have a collective average cell rate greater than 500000 cells/mL, on milks respectively of neighborhood of cow and of herd neighborhood.
