Abstract

This study was conducted to validate the effectiveness of feed ingredient metabolisable energy (ME) of meat ducks predicted with simulated digestion system. Firstly, the enzymatic hydrolyzate gross energy (EHGE) of corn, sorghum, soybean meal, rapeseed meal and wheat bran for chicken and duck were determined using the simulated digestion method, the ratio of EHGE for duck to chicken was calculated, based on this ratio, the ME for duck were calculated from the ME for chicken in each feed ingredient. Secondly, two thousand and four hundred 21-day-old Muscovy ducks were selected and divided into 8 groups with 6 replicates per group and 50 ducks per replicate. Ducks in each group were fed experimental diets with different ME levels. The average daily gain, average daily feed intake and feed to gain ratio were measured on 21 to 50 days of age, 51 to 75 days of age and 21 to 75 days of age, and the regression analysis of feed to gain ratio with dietary ME were established in each growing phase of ducks. The result showed as follows:1) the ratio of EHGE for duck to chicken in corn was 1.06, and the ratios of EHGE for duck to chicken in sorghum, soybean meal, rapeseed meal and wheat bran ranged were from 1.14 to 1.21. 2) Dietary ME level had no significantly effect on average daily gain of meat ducts in each phase (P>0.05), but had significantly effects on average daily feed intake and feed to gain ratio (P<0.01). 3) The correlation coefficient (R²) of regression equation of feed to gain ratio on for duck ME was higher than that for chicken ME. In conclusion, using predicted ME for duck to formulate meat ducks diet is more accurate, and it is feasible to establish ME database of feed ingredient for meat ducks by using simulated digestion method.
