ABSTRACT: Five castrated male
Iberian pigs (100 ± 2 kg b.w.) fitted with T-shaped ileal cannulas at the terminal
ileum were used to determine the effects of legume feeding on intestinal
microbiota composition. The diets were based on defatted soybean (Glycine max), lupin (Lupinus angustifolius) or chickpea (Cicer arietinum) seed meals and
contained similar amounts of digestible energy (14.2 - 15.1 MJ·kg-1)
and protein (107 g·kg-1). A hydrolyzed casein diet was used to determine
the bacterial counts in pigs fed on a vegetable-free diet. The composition of
the intestinal microbiota at the terminal ileum was analysed by q-PCR. Higher (P 10 number of copies was determined in the ileal contents of pigs fed on lupin- or
chickpea-based diets with respect to those fed on the soybean-based diet.
Bacteroides and the Clostridium coccoides/Eubacterium rectale group log10 number of copies was lower (P Escherichia/Shigella group log10 number
of copies was lower (P P Escherichia/Shigella group. This information suggests that lupin or chickpea
feeding might induce a benefit in the microbiota composition of Iberian pigs in
their final productive stages.
