BioFreeze™ – the new ‘Gold standard’ for intestinal sample collection

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, although freezing and thawing may lead to bacterial lysis and some loss of DNA.

Reverse peristalsis in the intestine of broiler chickens – is it important in practice or just a trivial observation?

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 reverse peristalsis were frequent and powerful, these characteristic features of different intestinal segments regarding biomarkers and dietary nutrients could not exist.
