"(10) Leaviug uuti-itive ingredients out of account none of the foods used seem to 

 have had any very special effect in increasing the quantity." 



Shelter for sheep, J. Scott {Trans. Eighland and Agl. ^ov. Scotland, 

 1894, x>P- 109-133). — A number of practical experiments on this subject 

 showed that ''slied- wintered slieep cat much less and yet i)r()duce 

 much more mutton in proportion to the quantity of food consumed than 

 others fed in tlie open field, exposed to all varieties of Aveather, and 

 inclined to take much more exercise." 



Feeding wheat to hogs, E. C. Chilcott {South Dakota Sta. Bui. 

 38, pp. Hi, plates J). 



Si/iwpsis. — Spring wheat, ground and nnground, ground peas, and ground corn were 

 compared on 4 lots of 2 ])igs each for 90 days. Hay and corn fodder Avere fed 

 with each grain. Peas gave the largest gain for the food eaten, followed by 

 corn, ground wheat, and unground wheat in tlie order named. With dressed 

 pork at 5| cts. per pound from 55 to 58 cts. per liushel was realized for the 

 wheat, 60 cts. for the corn, and 65 cts. for the peas. The pigs were fed too long 

 to secure the best financial results, some lots averaging 225 lbs. at the close of 

 the trial. 



To ascertain the feeding value of whole and ground wheat as com- 

 pared with peas and corn 8 pigs were fed in 4 lots for 90 days begin- 

 ning September ."). The lots were fed hay and corn fodder (witliout 

 ears) and the following grain ad libitum : 



Lot 1, Canada field peas, ground. 



Lot 2, spring wheat of rather poor (|uality, ungi'ound. 



Lot 3, Dakota-grown dent corn, ground. 



Lot 4, spring wheat, same as lot 2, ground. 



The grain for all w^as soaked in cokl water before feeding. A fifth 

 lot received kitchen slop, sour milk, whey, corn, peas, and wheat, and 

 no account was kept of the food eaten. 



There were 4 Poland Chinas and 4 crosses of Poland China with 

 Duroc Jersey. The pigs ranged from 80 to over 100 lbs. in weight. 

 Previous to the experiment they had been at pasture or fed on rape, 

 and received some grain in addition. They were bought at 4^ cts. per 

 pound, live weight, and sold at the close of the experiment at 5i cts., 

 dressed weight. The pigs were slaughtered at the close of the experi- 

 ment, and plates showing sections of the carcasses are given. At that 

 time the live weights ranged from 191 to 223 lbs. 



The results are stated in 3 periods of 25, 28, and 37 days, respect- 

 ively. The average results l)y lots for the whole experiment were as 



follows :
