Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

Advanced Science, Volume 12, Issue 42, November 13, 2025.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.

Hydrolysable tannin-based diet rich in gallotannins has a minimal impact on pig performance but significantly reduces salivary and bulbo-urethral gland size [PDF]

, 2017
Tannins have long been considered ‘anti-nutritional’ factors in monogastric nutrition, shown to reduce feed intake and palatability. However, recent studies revealed that compared to condensed tannins, hydrolysable tannins (HT) appear to have far less ...

Weight and season affects androstenone and skatole occurrence in entire male pigs in organic pig production

Animal, 2015
To investigate the extent to which the level of androstenone and skatole decreases with a decrease in live weight and/or age at slaughter of entire male pigs produced under organic standards, 1174 entire male pigs were raised in parallel in five organic ...

Ban on castration of boars in the Netherlands: modeling economic consequences of options [PDF]

, 2009
As a result of social criticism on castration, the Netherlands intend to start fattening boars. The great obstacle to a ban on castration is the expected negative effect on international trade because of the fear of boar taint.

Monitoring of behavior, sex hormones and boar taint compounds during the vaccination program for immunocastration in three sire lines [PDF]

, 2019
Immunocastration (vaccination against boar taint) is an alternative method to prevent boar taint without the need for surgical castration. This study investigates the evolution of boar taint compounds in serum and fat, serum steroid compounds as well as ...
