不同产茸性状梅花鹿粪便微生物多样性分析OA

In order to observe the fecal microbial diversity of sika deer with different antler production traits,160 healthy and male sika deer were divided into 8 groups and 20 deer in each group.The antler of sika deer was harvested and the yield was measured.Fecal collection and microbial diversity analysis were conducted.The experimental results showed that as age and saw type increased,the antler yield of sika deer showed a trend of first increasing,then decreasing,and then increasing again.The antler yield gradually increased from 2 to 6 saw,then decreased,and reached its peak again at 9 saw.The two antler production peaks were 6 saw and 9 saw,and the difference between the two was not significant(P＞0.05);The Chao1 index first decreased and then increased from 2 to 8 saws,gradually increased from 5 to 8 saws,and was the lowest at 5 saws,with significant differences compared to 7 saws and 8 saws(P＜0.05).The Observed_species index was the lowest in saw 5,with a significant difference compared to saw 8(P＜0.05).The Faith_pd index significantly increased with the increase of sawing and age(P＜0.05).The microbial community in the feces of 2～4 saws of spotted deer is relatively simple and unstable,while the microbial richness steadily increases after 5 saws.
