Drug Coatings for 

 Feed Pellets 



Either gelatin or soy oil may be used as drug carriers for coating feed pel- 

 lets. A representative sample of pellets should be checked for adequate 

 coatings before the operation is terminated. 



Gelatin: 125 grams gelatin in 3.0 quarts water per 100 pounds of pellets. 



(1) Slowly dissolve the gelatin into hot tap water. 



(2) Stir the drug into the gelatin solution until all lumps are gone. 



(3) Slowly add the drug-gelatin mixture to pellets as they are stirred by 

 hand or in a small cement mixer. To avoid pellet breakage, stir gently and 

 only long enough to assure an even drug coating. 



Soy oil: 2-3 pounds per 100 pounds of pellets. 



(1) Mix drug evenly in warm (100-120° F) oil. 



(2) Pour or spray mixture over pellets.
