70 Missouri Agricultural Report. 



lots 9 and 10, we find that lots 4 and 5 made together 200 pounds 

 gain from grass alone, or 100 pounds for each lot. If, however, we 

 assume that meat meal and tankage are of equal efficiency and 

 that lot 5 correctly represents them when fed to pigs on pasture, 

 and lot 9 when fed in dry yards, we have 43.4 pounds gain pro- 

 duced by each of lots 4 and 5 from the grass alone. Probably, then, 

 the grass produced somewhere between 43.4 and 100 pounds for 

 each of lots 4 and 5. Each pasture yard contained nine-tenths of 

 an acre, so that the pork produced by the grass itself per acre was 

 as follows, after deducting the amount of pork produced by the 

 full feed of concentrates fed the pigs : 

 Lot 



2. Corn meal 2, shorts 1, 278 pounds pork per acre. 



3. Corn meal 1, shorts 1, 247 pounds per acre. 



4. Corn meal 5, meat meal 1, 48 to 110 pounds estimated, pork 



per acre. 



5. Corn meal 5, tankage 1, 48 to 110 pounds estimated, pork 



per acre. 



In this connection it should be borne in mind that, besides the 

 pork produced, large though the amount is for lots 2 and 3, there 

 was cut off these yards the last of June 1.85 tons of hay per acre. 

 Further than this, as an offset to the expense of fencing pastures, a 

 great deal of labor is saved in caring for pigs if they have the run 

 of grass. No work was done for the lots on pasture beyond pro- 

 viding them with feed and water, and during the last month bed- 

 ding was taken to them, but the dry yards with their adjoining 

 sheds had to be cleaned at least once a week in order to keep them 

 in decent shape. On pasture the manure was naturally very well 

 scattered over the yards and did not accumulate perceptibly. 



"There was a striking difference in the amount of pork made 

 by the grass of the different lots. It is impossible to include corn 

 alone in this comparison, since no pigs were fed corn alone in the 

 dry lot, but of the rations compared above we find that with the one 

 having the least protein — corn two parts to shorts one part — the 

 gain from grass itself is largest; with corn one part to shorts one 

 the gain from grass is smaller, and with meat meal and tankage 

 the rations carrying the most protein, the gain from the grass it- 

 self is smallest."
