Poultry

The gastrointestinal tract (GIT) represents the greatest exposed surface to environmental factors (e.g., food, feed ingredients, microbes), and therefore, a wide range of factors associated with diet and infectious disease can negatively affect the delicate balance among the components of the chicken gut and, as a result, affect health status and production performance.

The impact on gut health often comes from microbial imbalance in the gut. Any gut damage caused by pathogens will also lead to poor gut health, which will, in turn, affect nutrient utilization efficiency. When feeding poultry, a goal should be to stabilize the microfloral ecosystem.

The gut is inhabited by hundreds of bacteria species. The larger the number of species, the greater ability to cope with minor changes in the gut environment. With major environmental changes species diversity declines and the microbial population becomes less stable. The diversity of microbial species is highly dependent upon the degree of competition for substrates. Competition for substrates between the bird and the microflora must also be considered. The gut is designed for the bird to get the “first bite of the nutrient pie.” If the diet is highly digestible, nutritional relationships between the host and the microflora are basically competitive, favoring the host. If diet digestibility is poor, more material moves to the lower gut and the nutritional competition between the host and the microflora is less competitive favoring the microflora. Therefore, dietary manipulations that improve digestibility allow the bird to get a bigger bite of the nutrient pie.

Improved digestibility can improve the health status of the bird’s GIT. Amaferm® has been shown to have an impact on the beneficial gastrointestinal, thereby enhancing the digestive efficiency of the gut and providing a source of energy. These improvements in the gut enhance nutrient utilization resulting in more energy for improved performance.

 

Gain and Efficiency

Feed costs represent about 70% of the costs of raising broilers. The best way to decrease these costs is to improve feed efficiency. Amaferm® has been shown to increase ADG by 1.6% and feed efficiency by 2.0% in poultry. These results show that the opportunity for growth and efficiency exists without the use of growth promoting antibiotics.
