Description The integration of livestock in the practices of conservation agriculture (CA) was assessed in Tunisian
semi-arid conditions. Forty five Barbarine lambs (aged 220 ± 10 days, average body weight 20 ± 2.5 kg)
were used in a performance trial, carried out in the experimental station of INRAT. During the
experiment, lambs were grazing on a plot of barley stubble cultivated according to CA was divided into
6 fenced equal subplots and to each subplot was assigned a stocking rate of animals (15 and 30 lambs
per hectare, SR15 and SR30 respectively). The biomass of stubble and its botanical composition were
estimated 2 times, using quadrats sampling technique. Live weight was determined 3 times after the
start of the experiment (three 15-days successive periods) to calculate live weight gain (LWG) and daily
live weight gain (DLWG). The amount of biomass varied (P
