Foreword  
 
This Kenya Standard was prepared by the Animal Feeds Technical Committee under the guidance of the 
Standards Projects Committee, and it is in accordance with the proced ures of the Kenya Bureau of Standards.  
 
It is expected that manufacturers will select their raw materials with both qualities of the product and economy of 
production in mind.  The choice of raw materials mixtures will therefore vary according to the local ity, season and 
availability of the ingredients.  
 
Proper formulation of diets for chicken  depends on adequate knowledge of their nutrient requirements.  
 
This standard  is intended to ensure that the diets of chicken  contain adequate amounts of nutrients an d that the 
intakes of certain nutrients are not excessive that they inhibit performance or impair health.  
 
 
During the preparation of this standard, reference was made to the following documents:  
 
  Genetic and nutrition development of indigenous chicken in Africa - O Khobondo, T K Muasya, S Miyumo, T O 
Okeno, C B Wasike, R Mwakubambanya, A M Kingori and A K Kahi
