 Foreword  
Development of the East African Standards has been n ecessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchange d 
within the Community will be removed.  
The Community has established an East African Standards Committee  (EASC)  mandated to develop and 
issue East African Standards  (EAS) . The Committee is composed of representatives of the National 
Standards Bodies in P artner States, together with the representatives from the public and private sector 
organizations  in the community .  
East African Standards are developed through  Technical Committees that are representative of key 
stakeholders including government, academi a, consumer groups, private sector and other interested parties. 
Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the 
Partner States. The comments received are discussed and incorporated before finalizati on of standards, in 
accordance with the Principles and procedures for development of East African Standards. XXXXXX.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore e xpected to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible for this document is Technical Committee EASC/TC 001, Animal feeding, feeds 
and feeding stuffs . 
This third  edition cancels and r eplaces the second edition EAS 55:2019 , which has been technically revised.  
Attention is drawn to the possibility that some of the elements of this document may be subject of patent 
rights. EAC shall not be held responsible for identifying any or all such p atent rights.  EAS 55: 2023

 Introduction  
To achieve efficient animal production, all nutrients should be provided in amounts necessary to 
meet the animal’s nutritional requirements. The formulation of balanced diets that provide the 
correct amounts and proportions of t hese nutrients is essential to support the requirements for 
maintenance and production. Nutrient requirements become defined accurately through research 
trials so as to formulate diets more precisely. The standards presented in this document give the 
restrictions required for the prevention of poor animal performance.  
Feeds may be produced by mixing various feeding stuffs or ingredients which may themselves 
vary in composition. The choice of raw materials mixtures will depend on locality, season and 
availa bility, economics, prices, quality and safety of the product. The chemical composition of 
feedstuffs plays an important role in formulation of balanced and economical rations for various 
classes of animals. This is only possible when knowledge of the chemi cal composition of 
feedstuffs is available. Studies on the nutritive value of feed stuffs available in the East African 
region show differences between analytical values .
