CONCLUSIONS. 



1. For each one hundred pounds of live weight eight 

 pounds of skim-milk and four pounds of corn meal make an am- 

 ple and well proportioned daily ration. 



2. In the absence of skim-milk, two and one-half pounds 

 of corn meal, two and one-half pounds of middlings, and eight 

 pounds of water, will give an equal amount of nutritive matter. 



3. One hundred pounds of digestible matter in the skim- 

 milk and corn meal ration was equal to one hundred and forty- 

 six and six-tenths pounds in the corn meal and middlings ration. 



4. The superiority of the skim-milk ration is due in part, 

 doubtless, to its greater digestibility ; but still more, in my opin- 

 ion, to the fact that there is less waste matter, that is indigestible 

 matter, to be crirried through the system, and to the noticeable dif- 

 ference in t-c character of the dung, mentioned by Prof. Morse 

 in Part II of this Bulletin. The pigs, on mixed grain invariably 

 grew constipated, while those on skim-milk was not so affected. 



5. The cost of a pound of gain on skim milk and corn 

 meal was three and six-tenths cents, on mixed grain ration, five 

 and two-tenths cents. 



6. Digestible dry matter required to produce one hundred 

 pounds of gain of live weight on skim-milk and corn meal, two 

 hundred and thirty-one pounds, on mixed grain, three hundred 

 and thirty-four and one-half pounds. 



( Lot I, when dressed, shrunk 19.6%.

 8. Calling skim-milk worth twenty-five cents per hundred 

 and we get the following balance sheet, on the basis of the cost 

 as given in " Conclusion No. 5 : " 

 30 lb. pig, first cost, $2.00 



170 lbs. of growth on skim-milk and corn meal, @ 3.6 cts., 6.12 



200 lb. pig cost, $8.12 

 which equals 4.06 cents per pound. 



30 lb. pig, first cost, $2.00 



170 lbs. of growth on com meal and middlings, @ 5.2 cts., ^8.84 



200 lb. pig cost, , $10.84 



which equals 6.42 cents per pound.
