FOODS ANIMAL PRODUCTION. 



375 



months old at the beginning of the experiment. They were kept in 

 separate pens, which were quite roomy. Both lots were fed 5 to 6 qt. 

 of skim milk daily. At the beginning of the trial, lot 1 was fed 4 oz. 

 of rice meal to a quart of milk and lot 2 4 oz. of corn meal. The 

 amount was gradually increased to suit the appetite of the pigs. 

 The amount of total solids in the skim milk was determined from 

 time to time. The composition of the rice meal and corn meal is given. 

 The two feeding stuffs have similar composition, "being comparatively 

 low in protein and high in carbohydrates. They both may be termed 

 heat-producing and fattening feeds. The rice meal contains more fat 

 and less extract or starchy matter than the corn meal." 



The results, which are expressed in tabular form for each pig, are 

 briefly summarized in the following table: 



Results of feeding rice meal and corn meal to jiii/s. 



"The above results indicate that a good quality of rice meal has a feeding value 

 equal to a similar quality of corn meal. 



"With grain at $18 per ton and dressed pork at 5 cts. per pound, skim milk returned 

 i ct. per quart, or 23 cts. per 100 lbs. ; with the same price for grain and dressed 

 pork at 6 cts. per pound, skim milk would return 31.5 cts. per 100 lbs. 



"With grain at $18 per ton and skim milk at 15 cts. per 100 lbs., live weight would 

 cost 2.88 cts. per pound and dressed weight 3.fi6 cts. If skim milk were reckoned at 

 25 cts. per 100 lbs., live weight would cost 4 cts. per pound and dressed weight 5 cts. 

 per pound." 



Oat feed vs. com meal (pp. 231-234).— This test, which began March 

 29 and lasted 3 months, was made with 6 Chester White pigs from the 

 same litter. They were divided into 2 lots, lot 1 consisting of 4 and lot 

 2 of 2 pigs. The conditions were the same as in the previous test. 

 The pigs were given at the beginning 5 qt. of skim milk per day, which 

 was gradually increased to 8 qt. At first lot 1 was fed in addition 

 2 oz. of oat feed and lot 2 2 oz. of corn meal to a quart of milk, the 

 amounts being increased later to satisfy the appetite of the pigs. The 

 composition of the oat feed and the corn meal is reported. The results, 

 which are given for each pig, are briefly summarized in the following
