| Abstract: | Fibre supplementation in sow nutrition is of special interest as it is a prerequisite to improve gut health and animal performance. Eubiotic lignocellulose (ELC) or standard lignocellulose (LC) can modulate intestinal microbiota compared to traditional raw ingredient fibre sources. The hypothesis of the study was that different dietary fibre sources could modulate intestinal microbiota differently in sows. Thirty mixed parity sows were randomly distributed among 3 treatments. During gestation, a treatment receiving a diet formulated with 15% soybean hulls (CON), a CON + 2.5% ELF or a CON + 2.5% LC; and during lactation, diet formulated with 5% soybean hulls (CON), a CON + 1.0% ELC or a CON + 1.0% LC. Plasmatic urea levels, fecal volatile fatty acids (VFA) and intestinal microbiome profile were evaluated from sows at 111d of gestation and 16d of lactation, as well as immunoglobulins in milk on d16 of lactation. Data analyses were realized using Bioinformatics Software Geneious®. On 111d, plasma urea levels were higher in CON (P=0.085) and the globulin levels were higher in ELC and LC at 16d (P=0.076). The percentage of IgG in CON milk was higher and IgA was higher in ELC (P=0.021). Acetic (P=0.047) and isobutyric (P=0.021) acid levels were higher in CON at 111d. In ELC, the relative abundance of the Euryarchaeota phylum was highest at 111d (P=0.08) and at 16d (P=0.047). At 111d, genera Clostridium_IV was more relative abundant in ELC (P=0.086). In ELC, the abundance of the genera Terrisporobacter was lower at 111d (P=0.017). At 16d, the relative abundance of the genera Clostridium_IV and Clostridium_XIVa was higher in CON (P=0.086/P=0.099). The genera Methanobrevibacter was observed in greater abundance in ELC at 111d and 16d (P=0.088/P=0.07). Our findings demonstrated that ELC could change immunological milk quality, modulate VFA production and alter the intestinal microbiome of sows. |
