and of ensilage, one dollar and forty eight cents, and allowance is made 
for a loss of one-third of the fertilizing constitutents in the growth 
of the animal. In estimating the net cost of producing pork at the 
_ Massachusetts Experimental Station, Dr. Goessman says: “ Ourallow- 
ance of a loss of thirty per cent of the essential fertilizing constituents 
eS. contained in the food consumed, in consequence of the development and 
‘ growth of the animal, is purposely a liberal one. The adoption of this 
. basis for our estimate tends to strengthen our conclusion that the raising 
_ of pigs for the home market can be made a profitable branch of farm 
_ industry, even with comparatively limited resources of skim milk.” * 
_ Inasmuch as the amount of manurial refuse recovered depends 
largely upon the facilities for saving the liquid manure, and the 
_ amount of cheap bedding material available, our principal compari- 
sons are made with the gross cost per pound of pork, the net cost, 
however, being also calculated. The cost of labor in feeding has not 
been included. The pork is valued at four and one-half cents per 
_ pound live weight. + 
The results show that with ensilage rated so low as one dollar per 
_ ton, the gross cost for production of pork was considerably more than 
its market value, when the proportion of ensilage was about 70 
per cent of the ration. When the ensilage averaged 69.8 per cent of 
the total food, its cost was 11.6 per cent and the manurial value 20.6 
_ per cent; and when it formed 44.2 per cent of the ration its cost was 
a 4.3 per cent and manurial value 9 per cent of the total food. With 
the cost of the ensilage rated higher, as is usual, the net costs under. 
_ the different rations would bear the same relations as the gross costs. 
‘Twice, for a month each time, during the experiment, the solid 
manure from the four pens was saved and weighed. There was not 
_ found much difference in the amount from the several pens, the 
_ average from all being .75 pounds dry manure per day for every 100 
_ pounds of pig, or 3.23 pounds fresh manure, the average of many 
_ determinations of moisture being 76.9 per cent (the lowest 69.6 and 
| the highest 84.6 per cent.) 
f The dried manures contained about 79 per cent of organic 
4 matter, those from ensilage-fed pens having 2.35 per cent of nitrogen 
and from the others 2.47 per cent, equal to .54 and .57 per

+ Some of the poorest pigs have been sold for three cents and some of 
the best for six cénts. Most of the pigs sold to local butchers have 
rought four and one-half cents per pound live yeni (This was in the 
itter part of 1889 and part of 1890.)
