Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry  of Tourism, Trade and 
Industry established under Cap 327, of the Laws of U ganda. UNBS is mandated to co-ordinate the elaboration 
of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(b) a contact point for the WHO/FAO Codex A limentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT/SPS Agr eements of the World Trade Organisation (WTO). 
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a gi ven field or area and consists of representatives of 
consumers, traders, academician s, manufacturers, governme nt and other stakeholders. 
Draft Uganda Standards adopted by the Technical Committ ee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council. 
This Uganda Standard, US EAS 233, Ostrich feed — Specification , is identical with and has been 
reproduced from an East African Standard, EAS 233:2001,  Ostrich feed — Specification and has been 
adopted as a Uganda Standard.  
This standard was developed by the Food and Agricu lture Standards Technical Committee (UNBS/TC 2).  
Wherever the words, "East African Standard" appea r, they should be replaced by "Uganda Standard."

Foreword 
 
Development of the East African Standards ha s been necessitated by the need for harmonizing 
requirements governing quality of products and services in East Africa. It is envisaged that through 
harmonized standardization, trade barriers which are encountered when goods and services are 
exchanged within the Comm unity will be removed.  
 
In order to achieve this objective, the Partner St ates in the Community through their National Bureaux 
of Standards, have established an East  African Standards Committee.  
The Committee is composed of representatives of the National Standards Bodies in Partner States, 
together with the representatives from the private sectors and cons umer organizations. Draft East 
African Standards are circulated to stakeholders th rough the National Standards Bodies in the Partner 
States. The comments received are discussed and in corporated before finalization of standards, in 
accordance with the procedures of the Community.  
East African Standards are subject to review, to keep  pace with technological advances. Users of the 
East African Standards are therefore expected to ensure that they  always have the latest versions of 
the standards they are implementing.
