Five groups, 70 birds/group. Dietary metabolizable energy densities (ME)/crude protein levels (CP) decrease from 2880 -2310 kcal/ 20 - 16 percent (1-3 week of age), 3094- 2406 kcal/ 18-14 percent (4-7 week of age), 3230-2470 kcal/I7-13 percent (8-12 week of age). The results showed that: The energy and protein levels vary with the rate of ME/CP 144 - 167 - 190 in the diet of the 3 phase starter, grower, finisher did not affect the survival rate, significantly affected and proportional correlation to growth and inversely correlated to feed conversion ratio
irregular influence to the carcass composition survey of experimental muscovy duck. Dietary metabolizable energy densities (ME) and crude protein levels (CP) of treatment III (2603 - 2750 - 2850 kcal and 18.1 - 16.0 - 15.0 percent CP) should be chosen to feed commercial France muscovy duck, at 12 weeks of age, average live body weight was 3470.74 grams, average day gain was 40.78 grams, feed conversion ratio was 3.02, performance index was 135.03, these results were better than those when comparing with lower ME and CP levels of treatments and the same performance when comparing with higher ME and CP levels treatments.
