Increased protein fermentation in the caecum and colon indicates poor ileal protein digestibility and produces harmful metabolites. Whenever there are negative performance effects with a new diet component, the quantification of protein fermentation biomarkers reveals whether the issue is connected to poor protein digestion.
Butyrate, a short-chain fatty acid (SCFA) of 4-carbon atoms, is generally considered to be the preferred energy source of epithelial cells in the large intestine. Once produced by bacterial metabolism in the intestinal lumen, much of the butyrate is absorbed, to benefit the host animal’s energy status.
A wide diversity of intestinal biogenic amines (BA) -producing and biogenic amines -degrading bacterial species have recently been identified. In short, undigested dietary protein that reaches the colon is fermented by microbes possessing amino acid decarboxylase activity into a range of BAs, along with other degradation products such as phenol, […]
When studying intestinal processes and microbe-mediated gut health, the first step is collection of digesta and/or feces specimens. Standardised sample collection and easy-to-use materials are critical when streamlining the sampling process, to generate reliable scientific data. Immediate freezing of samples is regarded as the gold standard of intestinal sample storage, […]
The suggestion of reverse peristalsis from caecum to small intestine has puzzled researchers at Alimetrics for a long time, since it is strongly contradictory to our general findings in analyses of bacteria and their metabolites along the intestinal tract of broiler chickens and the fundamental differences between intestinal segments. If […]
