oil. After the oil has been removed the remaining material 

 is dried so that it may be shipped, stored, and kept over 

 long periods of time. The poorer grades of tankage are 

 sold as fertilizer, and those portions that do not contain any 

 of the refuse of the digestive tract are sold for feed stuffs. 

 Tankage is especially valuable for feeding young pigs. 

 It is so high in protein that it should not furnish more than 

 lo per cent of the ration. It is an economical feed in spite 

 of its high price. Farmers who have no skim milk to feed to 

 young pigs should make large use of tankage. 



Blood Meal. — Dried blood meal is also very high in 

 protein material and is valuable to add in small amounts 

 to the ration of the pig and calf. Used sparingly it acts as 

 a corrective of stomach disorders. 



Meat Meal. — Meat meal obtained from refuse scraps 

 may be fed to advantage to young animals. Because of its 

 richness it should be fed sparingly. All of the slaughter- 

 house by-products that are sold as feed stuffs are so 

 thoroughly sterilized by the high temperature to which they 

 are subjected during the process of manufacture that no 

 contagious diseases can be contracted from their use.

Milk is nature's food for the young animal, and normal 

 milk contains all the nutrients in correct proportions for 

 its proper development. The nutrients in milk are highly 

 digestible. The first milk secreted by the dam after the 

 young animal has been born is called colostrum. It is high 

 in protein and has a laxative effect upon the young animal, 

 its purpose being to cleanse the digestive tract. After about 

 five days the milk of the cow is in normal condition.
