| Summary: | The objective of this work was to evaluate the milking conditions in 120 dairy herds in three regions of the Sahel of Tunisia: Sousse, Monastir and Mahdia. For this purpose, 707 lactating cows of Holstein Friesian, were considered. The average farm size in the three areas studied was 4.6 ha. Among the surveyed farms, 71% free stall. The study of the machine operating parameters to milk cows revealed that the pulse frequency (FP), the vacuum level (NV) and pulsation ratio (PR) are nonconforming respectively in 87%, 78% and 58% of cases. The study of the hygienic conditions revealed that 39% of milking machines (MAT) are of poor cleanliness and 51% of their pipes are in medium condition. Regarding milking practices, the most used method for cleaning teats is the collective mop with water (39%), without wiping (67%). The elimination of the first jets and the teat disinfection after milking were both omitted by 62% and 61% of farmers. The milking conditions deviate from best practice in several farms and they deserve more attention and equipment maintenance. |
