Statistical study of the feeding factor in samples of Iberian pig microbiome

Abstract

Abstract This study has investigated how the food factor influences samples of the intestinal microbiome of Iberian pigs from birth to 90 days of age. Three types of different diets in piglets were taken into account in it. The alpha diversity of the samples, their beta diversity and the beta dispersion of these were studied. It could conclude that Prevotella hominis is the specie that generates the greatest significant differences in relation to the comparisons of the different levels of feeding and it was evidenced that the microorganism can be a possible option as a probiotic in the feeding of post-weaning piglets. It was also evidenced that age generates phylogenetic distance between samples regardless of the food factor. It was also compared, by statistical inference, whether the composition of the samples in relation to the Phylum was different. The Shallow Whole Metagenomic Sequencing technique was implemented to obtain the abundances of microbiome samples in this study.
