PRINCIPLES OF FEEDING FARM ANIMALS 



low in feeding value. Thus such feeds should be purchased 

 only on a guaranteed analysis either from the manufacturer 

 or from the state authority having in charge the regulation 

 and inspection of commercial feedingstuffs. Many states 

 now have laws requiring that the minimum percentages of 

 crude protein and fat, and the maximum percentage of crude 

 fiber be printed on the container, or on an attached label. If 

 the feed is sold in bulk the dealer is usually required to furnish 

 a guaranteed analysis from the state authorities. Many 

 states require also that the ingredients making up the feed be 

 printed on the bag or label. Thus wheat bran which contains 

 ground screenings must be designated as '' bran with screen- 

 ings." Having the chemical analysis of the feed, the pur- 

 chaser should compare it with the average chemical analysis 

 of similar feeds as given in Table 28. If the feed in question is 

 much lower in crude protein and higher in crude fiber than the 

 average, it indicates that the feed is low-grade or adulterated. 

 The Texas Experiment Station ^ suggests that the follow- 

 ing standards be followed in bu\dng commercial feedingstufTs :
