Description The aim of this work was to study the effect of agricultural practices (Conventional or conservation agriculture: Conv. A and CA respectively) and the stocking rate on live weight variation of Barbarine ewes in semi-arid conditions. The trial was carried out in the experimental station of INRAT (Region of Zaghouan, 2014) in two plots of bread wheat stubble, cultivated respectively according to Conv. A and CA conditions. Forty Barbarine breed ewes (Average initial weight: 43 kg) were divided into 8 homogeneous groups of 5 animals each (4 groups for each agricultural system: Conv. A and CA). Two stocking rates of 15 and 30 ewes/ha (SR15 and SR30) were used in each agricultural practice. Animals grazed during a period of 60 days. In the second month, ewes received a supplementation composed of 250 g of concentrate. Ewes were weighted every 10 days. Live weight (LW) and daily live weight gain (DLWG) were determined.

Results showed that during the first grazing period, whatever the stocking rates, ewes lost body weight (P
