even a little bran when used for very young pigs, otherwise 

 it sometimes causes indigestion. Soaking for a few hours, 

 or scalding, improves it for young pigs. It combines well 

 with almost any kind of meal and makes a good food for 

 pigs of all ages. 



Bran. The use of bran in pig feeding is rather limited. 

 It contains too much fibre and is rather too bulky to be fed 

 in large quantities to pigs. Sometimes a little of it can be 

 used to advantage for the purpose of diluting or lightening 

 other foods, as has been indicated. It can be used in larger 

 quantity for matured breeding stock, where the object is to 

 hold the animals in light breeding condition. 



Oil Cake. As a rule, hogs are not particularly fond of 

 oil cake. A very small quantity may be used in the ration 

 of ntfrsing sows or young pigs after they are weaned. As 

 much as one-fifth of the total ration may be composed of oil 

 cake, if the pigs can be induced to eat it. Where skim milk 

 is available, the use of oil cake is of doubtful advantage. 



Gluten Meal. Gluten meal is similar in value to oil 

 cake and may be used in about the same way. 



Cottonseed Meal. This food has been largely experi- 

 mented with in the United States, but, up to date, no really 

 satisfactory reports have come to hand. There seems to be 

 something in it which acts as a poison to pigs and frequently 

 causes death. Further investigation is necessary before it 

 can be classed among the desirable foods for swine. 



Tankage. This is a by-product from the large slaughter 

 houses and varies considerably in composition. Very good 

 results were obtained with this food at the Ontario Agricul- 

 tural College, especially in cases where skim milk was not 

 available for young pigs. It seems to be well adapted to 

 feeding with corn, as it apparently furnishes a good deal of 

 the material in which corn is deficient. 



Blood Meal. This by-product of the slaughter house is 

 commonly recommended for feeding along with corn. At 

 the Ontario Agricultural College, where it was fed with
