Abstract / Zusammenfassung

The use of by-products from the food industry as ingredients for animal nutrition is a good strategy in relation to a sustainable food production.
We hypothesized that an 8% inclusion of carrot pomace (42.8 % insoluble fibre - IDF, 19.6 % soluble fibre - SDF), brewers ́ spent grains (BSG; 49.0 % IDF, 1.6 % SDF, 26.6 % crude protein) or carob pods (69.8 % IDF, 1.8 % SDF) in the diets for weaned piglets could positively
affect intestinal physiology and microbiota, without impairing performance parameters.Sixty-four piglets were distributed into four groups and allocated to floor pens containing two animals/pen (8 replicates/group). They received either a control diet or a diet including 8% of one of the tested ingredients, which were added in substitution of corn and, in the case of BSG, also soybean meal. Diets were isonitrogenous and isoenergetic. During the 4-week trial, body weight and feed intake were weekly recorded and at study end, jejunum tissue, proximal colon tissue and digesta, and faeces were collected after euthanasia of one piglet/pen. Data were analysed with one-way ANOVA (significance at p ≤ 0.05). Results on performance parameters were similar among groups during the whole trial, and no differences in jejunum villus or crypts or colon crypts were observed. Goblet cell counts in colon tissue were also similar among groups. No differences on the expression of genes related to barrier function or immune response were detected. Richness, Shannon and Evenness indices showed a higher bacterial diversity in faeces of the animals receiving the by-products. It can be concluded that a moderate inclusion of fibrous by-products did not affect performance in post-weaned piglets. All piglets showed good health status during the experimental period and we could not confirm if the changes in bacterial diversity might be positive in helping to cope against intestinal pathogens.
