EXPERIMENT STATION BULLETINS.

their respective feeds, after whicli tliey were again weighed for the ex- 

 periment proper. 



In these as in all the other tests the initial and closing weights were 

 each the average of three weighings made at 10 a. m. 2 p. m. and 4 p. m. 

 of the starting and closing days. 



As has been previously stated, it was the intention to start as nearly 

 as possible at an average of 150 pounds weight, and close the work as 

 soon as either pen averaged 250 pounds. 



Jn Comparison No. I, the feeding period was seventy days. In Com- 

 l)arisons Nos. II and III it was 56 days. However, in the case of Com- 

 parison No. I, two of the six pigs fed on the exclusive bean ration 

 went so badly off feed during the first two weeks that at the end of the 

 second week they were withdrawn from the experiment and the remain- 

 ing four weighed in again; consequently the gains for Pen 1 are com- 

 puted for eight weeks instead of ten, as in the case of Pen 2. 



The pigs used in Comparison No. I were Poland-China-Chester White 

 cross breds, purchased from a farmer near the College. Those used for 

 Comparison No. II were a Duroc-Jersey-Tamworth cross and those for 

 Comparison No. Ill were Berkshire-Tamworth cross breds reared at the 

 College. 



The following tables present the facts in condensed form, each of the 

 six pens being given a separate number to prevent confusion. In these 

 as in all other tables of this bulletin, cost of labor is not considered ;tnd 

 feeds are charged at the schedule prices previously given.
