This experiment was conducted to study the effects of dietary choline level on growth performance, slaughter performance and nutrient apparent availability of geese. One hundred and eighty one-day-old Qingnonghui geese were selected and randomly divided into 6 groups with 3 replicates in each group and 10 geese in each replicate. Geese in the six groups were fed the corn-soybean basal diets supplemented with 0, 600, 1 200, 1 800, 2 400 and 3 000 mg/kg choline, respectively. The experiment lasted for 15 weeks. The results showed as follows: 1) the supplementation of 1 800 and 2 400 mg/kg choline significantly increased average daily weight gain of geese aged 1 to 4 weeks and 5 to 15 weeks (P<0.05 or P<0.01), significantly decreased the ratio of feed to gain (P<0.05 or P<0.01), and reduced mortality rate. 2) The supplementation of 2 400 mg/kg choline significantly increased the percentage of eviscerated yield at 4 and 15 weeks of age (P<0.05), the supplementation of 1 800 mg/kg choline significantly increased dressing percentage at 15 weeks of age (P<0.05), and significantly decreased the percentage of abdominal fat at 15 weeks of age (P<0.05), but there was no significant difference in the percentage of half-eviscerated yield at 4 and 15 weeks of age among the six groups (P>0.05). 3) The supplementation of 1 800 mg/kg choline significantly increased the apparent availability of calcium, phosphorus, neutral detergent fiber and acid detergent fiber (P<0.05 or P<0.01), but had no significant difference in the apparent availability of dry matter, organic matter and crude protein among the six groups (P>0.05). In conclusion, the supplementation of choline in diets for Qingnonghui geese is feasible, and the optimum supplemental level is 1 800 mg/kg.
