- Abstract
Background: Humans and animals share their body with a complex microbial community, with which they have an intense relationship. It was shown that microorganisms influence a myriad of host functions, for instance, the immune system. This strong connection has a significant impact on the health and wellbeing of animals, making microbiota an essential factor in animal production. Understanding the key factors affecting microbiome composition can be a great advantage in the development of new feeding protocols and optimising animal husbandry. Objectives: With the present work, our goal was to get an insight into the pig gut bacteriome variation of different feeding groups. Materials and methods: We have collected samples from five feeding groups in a large scale pig farm, pooled the samples in each group and analysed the sequences of the DNA content using next-generation sequencing technologies. The Kraken software was used to fit the reads to the NCBI nt database. During further analysis, we used only the reads fitting to taxa from the Bacteria kingdom. Examining population characteristics, we calculated the total taxon counts and Shannon diversity for each group. The compositional similarities were determined by the NMDS dimension reduction using Bray-Curtis distance metric and the core bacteriome was also analysed for a more detailed look. Results and discussion: We found that a-diversity increased in line with the age of animals. It was in agreement with previous results from studies of human and swine intestinal microbiome, although several findings were suggesting a plateau of the diversity. In contrast with the usually experienced increased variety in pregnant sows, we found the lowest numbers in this group. In the genus level composition of the samples, we found more or less disagreement between our results and previous findings, indicating that various factors are influencing the formation of the microbiome. Examining the effect of feed components on the microbiome, we were not able to reveal any significant connection.
