0 Foreword  
 
Blood meal is one of the important animal by -products, which  can be used as a protein 
supplement in animal feeds. It has a great potential in the country if the quality o f the material is 
ensured. Therefore , the preparation of this standard is deemed necessary in order to help both 
the producers of blood meal as  well as the feed manufacturer s to produce safe and quality  feed 
products.  
 
In the preparation of this Tanzania standard assistance was derived from IS 7060:1973 – 
Specification for blood meal as livestock feed  published by Indian Standards Institution.  
 
In reporting the results of a test or analys is made in accordance with this Tanzania S tandard , if 
the final value  observed or calculated is to be rounded off, it shall be do ne in accordance with 
TZS 4  (see clause 2) . 
 
 
1.0 Scope
