    Description And Variation Factors Of Individual Cell Counts Of Milk In Of Units Bovins Aboveground (tunisian Sahel)
    (University of Eloued جامعة الوادي, 2016-01-01) M’sadak, Y.; Haj Mbarek, R.; Mighri, L.
    This study has as essential objective the diagnosis of breast health of a sample of 120 cattle farms conducted in above ground in the Tunisian Sahel, from the Individuals Cellular Counts (ICC). The analysis of the ICC has inferred that the infection status of the breasts is worrying (50% of the sample is infected). Depending on governorates, Sousse always haves the highest ICC, followed by Monastir with lower ICC and finally Mahdia with the lowest ICC. The determination and distribution of arithmetic averages (AA), geometric averages (GA), the quartiles and interquartile of ICC, led to highlight that AA of ICC are always higher than the GA of ICC. The median is closer to GA of ICC than AA of ICC, confirming the utility of the use of the GA in the cell distribution. The rank and stage of lactation, season of calving and milk production have importance on the evolution of the ICC.

    Factors Livestock And Milking Associated With Risk Of Mastitis In Cattle Dairy Farms In Aboveground Of The Tunisia Coastal Semi-arid
    (University of Eloued جامعة الوادي, 2013-07-01) M’sadak, Y.; Mighri, L.; Haj Mbarek, R.; Kraiem, K.
    This study was carried out in the Sahel of Tunisia (Monastir region) on a sample covering 40 cattle herd’s type above ground. We deduced the mastitis risk factors during the survey during visits for breeding and milking as well as from morphological and hygienic cow’s assessments. The data’s descriptive analysis has highlighted some significant effect factors on cellular levels and the risk of developing mastitis. For individual cell count (ICC), the significant effect factors (P <0.05) are: free stall, milking machine cleaning with only water, the poor condition of the piping, not elimination of the first milk jets and bad cleanliness of udders and the back legs of cows, whereas the herd cell count (HCC), the significant factors (P <0.05) are: cleaning the milking machine with water only, the frequency pulse (FP) is too high or low.
