Abstrakt: The porcine gut microbiome is central to animal health and growth as well as it can be structurally or functionally reshaped by dietary interventions. The gut microbiota composition in relation to Cyberlindnera jadinii yeast as a protein source in a weanling diet was studied previously. Also, there is a mounting body of knowledge regarding the porcine gut microbiome composition in response to the use of rapeseed (Brassica napus subsp. napus) meal, and faba beans (Vicia faba) as protein sources during the growing/finishing period. However, there is limited data on how the porcine gut microbiome respond to a combination of C. jadinii yeast in the weanling phase and rapeseed meal and faba beans in the growing/finishing phase. This work investigated how the porcine faecal microbiome was changing in response to a novel yeast diet with a high inclusion of yeast proteins (40% of crude protein) in a weanling diet followed by a diet based on rapeseed meal and faba beans during the growing/finishing period. The faecal microbiomes of the weanling pigs fed yeast were more diverse with higher relative abundance of Firmicutes over Bacteroidetes compared with those of soybean meal-based diet fed weanlings. Reduced numbers of Prevotella in the yeast fed faecal microbiomes remained a microbiome characteristic up until two weeks after the yeast diet was changed to the rapeseed/faba bean growing finishing diet. A number of differentially abundant bacterial phylotypes along with distinct co-occurrence patterns observed during the growing/finishing period indicated the presence of a "carry-over" effect of the yeast weanling diet onto the faecal microbiomes of the grower/finisher pigs.
