The productive response of Californian rabbits fed with hydroponic green oats forage (HGOF) as a partial replacement of commercial concentrate (CC) was evaluated under desert conditions in northern Chile. Five treatments were established as follow: 0, 25, 50, 75 and 100% replacement of daily diet with HGOF, which was harvested and used directly at 10 days after sowing. Forty-five rabbits weaned at 31 days were evaluated in a completely randomized design until slaughter weight of 2.0 kg. HGOF quality was considered as good, presenting similar nutritional value to CC. The variables assessed and range values were: average dry matter intake (59.17-104.73 g/d), average weight gain (16.35-29.10 g/ rabbit for day), feed conversion average (3.31-3.93 kg DM/ kg LW), time of weight at slaughter (53-91 d), final weight (1430-2044 g/ rabbit), carcass weight (1235-1385 g/ rabbit) and dressing out percent (59.19- 62.25%). The replacement up to 50% of the basal diet with HGOF did not affect significantly (P < 0.05) the feed intake, time of weight at slaughter, final weight and dressing out percent, making feasible its use as alternative forage on diet of fattening rabbits under desert conditions.

Palabras clave : Dressing out percent; feed intake; final weight; rabbits; time of weight at slaughter.
