Important Announcement

As from this date we advise all authors planning to submit papers to LRRD that we will no longer publish papers based on research in which the welfare of animals was compromised by surgical modification or the use of methods that generate stress and discomfort. These include procedures that modify the digestive track that were mostly developed to facilitate measurements of digesta flow in both ruminant and monogastric animals. We believe that these procedures are no longer relevant in view of developments in in vitro systems for which sources of microorganisms can be obtained from slaughtered animals.

We trust that readers of LRRD will agree with us since the welfare of animals is of primary concern and should not be jeopardized by surgical or management procedures which cause serious discomfort to the host animals.
