Practical case: Advantages of using phyto-active ingredients during a feed passage outbreak

One of our core missions ​​is to provide practical solutions to real problems of poultry farms.

A few weeks ago we wrote a post on signs and possible causes of the presence of undigested feed in poultry droppings, that you can read here. Today we would like to give a practical example of how a synergistic mixture of cinnamon and marjoram improves the functioning of the digestive system in a severe feed passage outbreak caused by dysbacteriosis.


The feed passage outbreak happened during winter 2013-2014 in two different farms located in the same area.

The broilers showed the following signs:

  • Droppings contained undigested feed visible to the naked eyes and had orange color.
  • Birds were poorly pigmented and the flocks lacked of uniformity.
  • Feed intake was low.
  • Intestines were congested.
  • There were severe erosions in gizzard.

In each of the two affected farms, one house was administered a cocktail of cinnamon and marjoram extracts through drinking water (PlusProtect Digestive©) for one week. Other houses were not treated. We observed flock status, appearance of feces, feed intake and necropsy findings before and after the administration of PlusProtect Digestive©. Alive weight and mortality were recorded some days after the experiment.

The combination of cinnamon and marjoram, contained in PlusProtect Digestive©thanks to its microbiocide and antioxidant effect,  has a very positive effect on the functioning of digestive system and the productivity parameters during feed passage outbreaks.
