Abstract: To investigate the effects of green forage on growth performance of Magang Goslings（1-28 days old）， 100 healthy Magang goslings（1⁃day old）from the same batch were randomly divided into experimental group and control group（n=50）with 5 replicates per group and 10 geese per replicate，and were fed until 28 days of age. During the experiment，both groups were provided with ad libitumaccess to feed and water，and the experimental group was fed a diet that included both formula feed and green forage，while the control group was fed only formula feed. The survival rate，daily feed intake，body weight and body size of goslings were recorded，and the ratio of feed to weight was calculated. The findings indicated no significant differences in body weight，daily gain and feed to gain ratio between the two groups during the initial 1 ⁃ 14 days. However，from day 15 to 28，the feed to gain ratio of the experimental group were significantly lower than those of the control group（P<0.05），while daily weight gain and the body weight of d21 and d28 was significantly higher than that of the control group（P<0.05）. There was no significant difference in body size between the two groups at the early stage of brooding，but at d28，the individual size indexes of the experimental group were higher than those of the control group（P<0.05）. The results showed that the addition of green forage in the brooding stage of Magang geese could promote the growth and development of geese and reduce the feed⁃to⁃weight ratio. This experiment provides a reference for the addition of green forage in large⁃scale breeding of Magang geese，but the amount and proportion of specific green forage added and its impact on subsequent breeding geese still need to be further explored.
