Effect of sweet lupins on duckling growth.

1. The feeding value of sweet White Lupin (Lupinus albus variety Buttercup) for Pekin (Cherry Valley) ducklings was evaluated in isocaloric and isonitrogenous diets formulated to contain 0, 100, 200, 300 and 400 g/kg lupins. Male and female ducklings were housed together and fed on starter diets from 0 to 3 weeks and finisher diets from 4 to 7 weeks. 2. Inclusion of sweet lupins at 400 g/kg diet (containing less than 0.1 g/kg alkaloids) had no deleterious effects (P < 0.05) on live weight, efficiency of food utilisation, dressed carcase weight and carcase fat content.
