200 Agricultural Experiment Station, Ithaca, N. Y, 



The total dressed weight of Lot I was 1,331 pounds and the aver- 

 age loss in dressing was 14.-i6 per cent. On the supposition that 

 the pigs at the beginning of the ex})eriraent would lose the same 

 per cent, in dressing as the average of all the lots at the time of 

 slaughtering (16.01 per cent.), there was produced during the time 

 of the experiment 1022.87 pounds of pork. The cost of the grain 

 fed this lot was 838.20, that is allowing 60 cents per bushel for the 

 wheat and 10 cents per cwt. for grinding. Allowing the milk to be 

 worth 15 cents per cwt., the total cost was $50.37, or $.04:9 per 

 pound for the pork. 



During the same time and on the same basis Lot II produced 

 1120.20 pounds of pork at a cost of 8-0456 per pound. The corn 

 meal was computed at 823 per ton, the average price for which it 

 sold during this time at the Ithaca miUs. Gluten meal was pur- 

 chased at $17.50 per ton delivered at Ithaca. It must be remem- 

 bered that the above calculations are made on the market prices of 

 grain during the experiment and that the price of wheat was unusu- 

 ally low, while the price of corn was considerably above the average 

 for the last four or live years for which it has been sold in the 

 market. Notwithstanding all this, the corn produced pork at a less 

 cost per pound than did the wheat. 



In the illustrations, No. 1 represents Pig No. 1 of Lot I and 

 No. 2 represents Pig No. 12 of Lot II. It will be observed that 

 Pig No. 1 represented almost exactly the average in weight for 

 Lot I, and that Pig No. 12 was only a little heavier than the aver- 

 age for Lot II. 



From the same lot of pigs from which Lots I and II were taken 

 twelve more were selected and divided into two lots of six each, 

 making the two lots as nearly alike as possible and numbered Lots 

 III and IV. 



Lot III was fed corn meal and water, no other food being given 

 from October 10, 1891 to February 10, 1895, the time of slaugh- 

 tering. 



Lot lY was fed two parts corn meal, one part meat scrap, and 

 water. Lots III and IV w^ere the same age and breeding as those 

 described in the previous experiment. The object in feeding these 

 two lots was to compare nitrogenous and carbonaceous rations as a 

 food for pigs, both as to growth of the animals and the comparative 

 amount of lean meat produced by these foods. As these animals 

 were of the same age and breeding, and about the same weight at
