 Compounded h orse  feed – Specification   
 
0   FOREWORD  
 
Horse ( Equus feruscaballus ) is a hooved (ungulate) mammal , a subspecies of the family 
Equidae . Proper formulation of diets for horses depends on adequate knowledge of their 
nutrient requirements. This standard is intended to ensure that the diets of horses  contain 
adequate amounts of nutrients for balance d grow th and performance .  
 
This standard has been prepared to ensure that compounded horse  feed manufactured or 
imported into the country are safe and m eet the nutritional requirements of horses.  
 
In the preparation of this Tanzania standard assistance was drawn  from KS 1742:2013 Horse 
feed supplement – Specification  published by Kenya Bureau of standards . 
 
In reporting, the results of a test or analysis made in accordance with this standard, if the final 
value observed or calculated, is to be rounded off, it sha ll be done in accordance with TZS 4 
(see clause 2).  
 
1.0 SCOPE  
 
This Tanzania  standard specifies requirements, methods of sampling and test fo r 
compounded horse feed.
