Items	Groups		SEM	p-Value
	R0	R400
Initial BW (g)	35.13 ± 0.41	35.12 ± 0.36	0.37	0.754
Final BW (g)	647.83 ± 20.20	661.43 ± 15.09	9.41	0.005
ADFI (g/day)	61.08 ± 1.89	59.61 ± 1.63	1.69	0.727
ADG (g/day)	21.88 ± 0.27	22.37 ± 0.19	0.33	0.005
F/G (g/g)	2.79 ± 0.10	2.66 ± 0.08	0.97	0.182

Note: The values are shown as mean ± SD of 140 individual male ducks. SEM: total standard error; p < 0.05 represents a significant regression relationship; p is the comparison value of the two groups. ADG: average weight gain, ADFI: average daily feed intake, F/G: the ratio of feed to gain.
