C. FEED STANDARDS. 



A standard for comparison is always necessary in passing accurate 

 judgment on the quality of concentrated feed stufTs. The percent- 

 ages of protein and fat serve as an index of the character of such 

 feeds in the majority of cases.' The various concentrates should 

 maintain the following percentages of protein and fat in addition to a 

 good physical and mechanical condition to be of standard quality. 

 Failure to substantially meet these requirements, indicates inferiority 

 or adulteration, in proportion as it falls below. 



> Among the exceptions are mixed soods and fortified feeds of a relativelylow Protein 

 content where a fiber cletermination and possibly a microscopical examination is needed tc 

 show the nature and quality of the product.
