Abstract:The purpose of this experiment was to study the effect of coconut water wet feed after natural fermentation on the growth of Wenchang chicken.The experiment selected 40 Wenchang chicken seedlings，which were basically out of the shell，and were set to 2 groups，20 in each group.There were 10 cocksandhens each.The control group was fed commercial feed and tap water，and the test group was fed with commercial feed and coconut water after 3 days of natural fermentation；starting from 1 week of age，the ratio of feed water to 1 ∶1（mass ratio）wet mix was used to feed 50 % natural fermented coconut water allows it to drink freely.The test period was 5 weeks.The daily weight gain，body odor and stool odor of the chickens are measured.The results showed that at 5 weeks of age，the live weight of male and female chickens in the experimental group after feeding for one month increased by 12.03 % and 9.97 %，respectively.The average daily gain of each group increased by 11.88%and 9.90%，respectively.Compared with the control group，the fecal odor was lighter and the color was not significantly different.The ammonia nitrogen content in the male faeces of the experimental group was decreased by 32.18 % and 26.40 %，respectively.The content of indole acetic acid was lower than that of the control group 42.69 %，40.82 %.Tests have shown that natural fermentation of coconut water for a certain period of time could help promote the growth of chickens，improve the body odor of chickens，and reduce the odor of chicken feces，which might be related to the potential improvement of intestinal health.
