Feed holds the key to a healthy young animal gut
Ensuring that the gut is healthy is critically important for all of life’s activity, since all nutrients must of course be absorbed through the gut. The right raw material choice therefore, limits the growth of pathogenic bacteria in young livestock animals.

The gut is the single largest immune related organ of the body and is the primary barrier between a bacterial milieu and the body per se. This barrier balances the need to support entry of nutrients through the gut wall while blocking the entry of microbes. This balance can be affected both positively and negatively by the composition of the diet along with the exposure of the body to pathogenic challenges. Young animals experience a tremendous change in gut size and function in order to support the required absorption of nutrients with the development of size, enzymatic production and function, along with establishment of a microflora population that supports the normal functions of the gut.
Vulnerability from birth
Intestinal microbial population establishment occurs in all species as the animal is born or hatched and is then exposed to environmental populations of bacteria that ultimately become established within the gut as the commensal population for the animal. The development of a ‘normal’ gut microbial community will ultimately buffer the animal from the onslaught of pathogenic microbes throughout life.
The consequences of poor microbial population establishment include a compromise in the animal’s ability to resist pathogenic microbial attack and/or the ability to even function properly. This can be seen when the animal is exposed to dietary challenges that may normally be associated with a mild or even unseen perturbance but which without a properly established microbial population may result in diarrhoea challenges without the presence of any pathogen. Ultimately, the establishment of a complex and diverse microbial population within the gut, buffers the animal from dietary and environmental challenges. Anything that affects the intestinal epithelium such as intestinal pathogens will result in an impaired feed utilisation, and often treatment with antibiotics to manage these challenges. In addition to that, immune responses and the repair of tissue costs energy and other nutrients, consequently affecting the performance. Many raw materials used in feed production bring a mix of positive and negative aspects that must be managed appropriately to result in a final feed that can be tolerated well by the animal.
