Maintien en État de Fonctionnement des Machines à Traire en Pot pour Vaches dans la Région de Sousse (Tunisie)

Abstract

The objective of this study was to diagnose the situation and the state of

operation of milking machines in jar in Sousse region, semi-arid littoral zone of

Tunisia. This study was performed in among a sampleof 30 small and

mediumdairy cattle farms aboveground. These herds subjected to mechanical

milking in jar, have a size of 3 to 25 Lactation Cows per herd (average 10). The

diagnosis implemented consists essentially to detect the identification and the

main technical characteristics, to visually assess the general condition of

cleaning and maintenance of equipments of milking and to test partially their

operation, using a pulsator tester. This diagnosis revealed that milking

equipment encountered is diverse on plans brand andorigin and that is mainly

poorly cleaned and poorly maintained. In addition, operation milking machines

controlled was not satisfactory in most cases. Someabnormal failures

werenoted for parameters of vacuum and pulsation. The effects of the milking

machine and of the milking of cows on mammary health remain to be

evaluated for a better control for mastitis treatment.
