摘      要：The influence of nanocrystalline cellulose(NCC) supplementation on growth performance, carcass traits,intestinal development, and lipid metabolism was assessed in 600 one-day-old male meat ducks(Cherry Valley ducks) from 1 to 35 d of age. Diets were supplemented with 0,200,500,800 and 1,500 mg/kg NCC during both the starter(1-14 d) and grower(15-35 d) phases. Each dietary treatment consisted of 8 replicate cages of 15 birds. Supplementation of NCC was associated with dose dependent increases in BW gain and feed intake(P 0.01) during 1-14 d of age and in BW at 35 d of age. As NCC content increased,the percentage of breast meat weight(P 0.05) and leg(with bone) weight(P 0.05) linearly increased,while the percentage of abdominal fat weight(P 0.01) linearly *** in ducks at 35 d of *** of NCC resulted in a dose-dependent increase in the weight(P 0.05) and density(P 0.01) of the cecum. The percentage of total hepatic lipid content(P 0.01) at 14 d of age and serum triglyceride(TG) concentration(P = 0.052) at 35 d of age linearly decreased with increasing of dietary NCC addition. In conclusion, inclusion of 1,500 mg/kg NCC in feed resulted in the greatest improvements in duck performance, intestinal development and lipid deposition.
