Mitigating chronic gut inflammation in animal production


Inflammation is a complicated physiological process in response to various immune stimuli. This physiological reaction can become detrimental when the response is prolonged and dysregulated called “chronic inflammation”. A notable feature of chronic inflammation is its high energetic cost.

t is well established that the chronic (low-grade) inflammatory response in the intestine, results in the disruption of digestive function, nutritional malabsorption, and consequently growth retardation.


Research has demonstrated that pro-inflammatory pathways promote muscle catabolism to supply amino acids and energy substrates for immune responses. These shifts in systemic metabolism may also explain the detrimental effects

on performance and carcass traits commonly associated with chronic inflammation which results in economic losses.


Real conditions A holistic approach that demonstrates several, complementary modes of action is necessary for overall protection against chronic inflammation. In our re- search, first, we established successfully, a ‘chicken chronic gut inflammation model’ under real production conditions.
