Abstract:

In order to explore the effects of sulfamonomethoxine (SMM) addition into the drinking water during breeding on the structure of fecal bacterial community of laying hens, a total of 260 Hailan brown laying hens were randomly divided into two groups (group A1: no SMM was added into drinking water; group B1: SMM was added into drinking water), and fresh feces were collected on the 5th day of feeding. Then, no SMM was added in group B1, and this group was renamed as group B2, and group A1 was renamed as A2 (as the control of group B2), and fresh feces were collected again after 7 days of feeding. The total DNA was extracted and sequenced by Illumina MiSeq platform. Based on the variable region of V3-V4 of 16S rDNA, diversity and fecal microbial community structure were analyzed. The addition of SMM reduced the bacterial diversity and richness of the laying hens, but the abundance of Lactobacillus and Acinetobacter were significantly (P<0.05) increased. One week after stopping SMM addtiion, the bacterial diversity and richness of the laying hens recovered, and the abundance of Acinetobacter was significantly (P<0.05) decreased. It was concluded that feeding SMM could change the structure of the intestinal community of laying hens, yet the intestinal community could recover after discontinuation of SMM feeding. The results increased insight into the harm of antibiotics and provided references for the standard use of antibiotics.
