teen weeks at a time. Considerable restraint is also put on experi- 

 mental pigs by way of confinement in pens and yards. In all the cases 

 reported the pigs were continuously confined in pens eight or ten feet 

 by fourteen feet, with outdoor yards of the same width as the pens, but 

 twenty-two feet long. 



PART 1. 



Digester Tankage vs. Skim Milk for Growing Sicine. 



This experiment consisted of a series of three tests, under practically 

 the same general plan, so that the work may be said to have been re- 

 peated three times. The six pens of pigs reported in this experiment 

 completed the feeding periods successfully. Additional pens were 

 started but were discarded owing to the development of undesirable 

 factors such as unthriftiness of an individual or other causes likely to 

 afifect the accuracy of the results. The surrounding conditions were 

 alike in every respect except that the two pens of pigs of the first series 

 were fed during the winter season and the others during the summer. 



TEST NO. 1. 



Digester Tankage vs. Skim Milk for Pigs Between Four and Six 



Months Old. 



In this test the ration for lot I consisted of cornmeal 3 parts, 

 middlings 3 parts and tankage 1 part, mixed with water; for lot II 

 corn meal and middlings equal parts, fed with a little more than their 

 own weight of skim milk. 



The pigs used in this case were Yorkshires and Poland Chinas; the 

 former were farrowed September 30th, and the latter September 15th, 

 1904. As this feeding period began January 25th and extended to 

 March 22, 1905, covering fifty-six days, the Yorkshires were 117 days 

 old at the start and the Poland-Chinas 132 days. There were five pigs 

 in each pen consisting of four Yorkshires and one Poland China. The 

 results are summed up in the following table: , 



During the 5^5 days of this test the five pigs of Lot I consumed an 

 average of 3.5 pounds of meal mixture per head daily, while increasing
