Feeds and Feeding. 



It is not entirely safe to place pigs with fattening cattle that 

 are being fed cotton-seed meal. Whether the trouble comes to the 

 pigs from working over the droppings of the steers or from eating

 this high value to the good effect of roots on the digestive organs. 

 Root-fed pigs utilized their food better than those getting no roots.
