Differents programmes of feed restriction have been evaluated on goose breeders kept outdoor in order to evaluate whether the spontaneous over-consumptions of feed which occur before the beginning of laying and after the peak of lay, play an important role on performances. During two successive trials, a limitation of the energy intake at 700 kcal ME/day/bird (320 g/day of a feed containing 2200 kcal ME and 170 g CP/kg) was applied from mid-november up to the date on which the laying rate reached 20% (about mid-february). This treatment induced a small, non significant reduction in the number of laid eggs and a large increase (+10 to +15%) in fertility with a positive balance of +4 goslings/goose. Two other levels of restriction (500 and 1000 kcal ME/day/bird) were tested on the same part of the laying cycle ; they appeared to be too much and not severe enough respectively. A restriction level which limits the geese body weight increase to 1.0 - 1.2 kg could be recommended. After the peak of lay (end of march), a limitation of the energy intake at 660 kcal ME/day/bird was detrimental to the laying rate (-6 eggs/goose) but is still largely favourable to the fertility rate (+15%). For this period, different feeding programmes would be probably justified for geese and ganders.
