On most farms the supply of milk will be limited and in these cases 

 the same Station recommends the following rations: 



RATIONS FOR GROWING PIGS. 



Weight of pigs. Rations. 



I. 20 to 180 pounds ,3 ounces of corn meal, wheat, rye , or hominy 

 meals to each quart of milk, and then grad- 

 ualy increase meal to satisfy appetites. 

 20 to GO pounds Milk at disposal, plus mixture of one-third 

 corn meal, one-third wheat bran, and one-third 

 gluten meal to satisfy appetites. 

 II. 60 to 100 pounds Milk at disposal, plus mixture of one-half corn 

 meal, one-fourth wheat bran, and one-fourth 

 gluten meal to satisfy apetites. 

 100 to 180 pounds Milk at disposal, plus mixture of two-thirds 

 corn meal, one-sixth wheat bran, and one-sixth 

 gluten meal to satisfy appetites. 

 20 to 60 pounds B ounces of corn meal to each quart of milk, 

 and 4 ounces of gluten feed as a substitute for 

 quart of milk. 

 III. 60 to 100 pounds Milk at disposal, and mixture of one-half corn 

 meal and one-half gluten feed to satisfy appe- 

 tites. 

 100 to 180 pounds 



Whey has a feeding value about half that of milk. It should be fed 

 carefully as it frequently causes stiffening of the joints and lameness. 



Dairy by-products obtained from the creamery, cheese factory or 

 skimming station should be pasteurized before being fed. If the feeder 

 used only those produced on his farm, and knows that his cows are 

 free from tuberculosis, this precaution is unnecessary. 



THE USE OF PASTURE AND FORAGE CROPS. 



The proper use of pasture and forage crops in hog feeding is another 

 means to decrease the amount of grain needed and add to the profits. 

 Grain feeding is always expensive and pasture crops usually give a 

 cheap source of very nutritious feed. By pasture crops I mean not 

 only the grass of the permanent pastures, but such crops as clover, 

 rape, vetches, and the cereals. These feeds have an effect on the pig 

 somewhat similar to that of skim milk; that is to say, they reduce largely 

 the amount of grain needed for a given gain, and add very much to 

 the health and vigor of the hogs. They are useful not only for their 

 actual feeding value but for their effect on the condition of the diges- 

 tive organs. As there is a great mass of experimental data on this sub- 

 ject, 1 will refer to it only in a general way. 



Generally speaking, pasture alone is not better than a maintenance 

 ration for pigs, and the feeder cannot expect to fatten his hogs in this
