Dec. is, 1925 Influence of Field-Pea Rations on Quality of Pork 1175 
RESULTS 
All lots in both parts of this series were provided with comfortable 
accommodations. Weight records were made of each pig every 
14 days. The initial and final weights of each test represent the 
average weight of three consecutive days, the second of which marks 
the beginning and close of the test. 
The hogs were marketed at a packing plant in Moscow, Idaho. 
Careful records were kept on each lot as to dressing percentages, 
shrinkage in the cooler, and gains or losses in the curing and smoking 
processes. Physical observations were made as to the quality of pork. 
For the determination of the melting points and iodine values, 
samples of fat were taken from the middle of the back and from the 
leaf after the carcasses were chilled. Each sample was rendered 
separately and poured into small glass bottles. All chemical analyses 
were made according to the Official Methods of the Association of 
Official Agricultural Chemists. 8 
The composition of all feeds used was as follows:

Tables II, III, and IV are introduced to show the average daily 
gain, the amount of feed per 100 pounds gain, and the dressing per¬ 
centages of each lot under the two types of feeding. 
An economy of gain is registered in the peas-following-forage lot 
in Table IV as compared to the pea lot in Table III. A forage period 
has the same effect in the case of all other lots. 
The dressing percentages of the pea-fed lots were somewhat lower 
than those in the other lots. It appeared to be the tendency of the 
: )ea-fed hogs to grow rather than to fatten, which will account for the 
ower dressing percentages. It will be noted that the feed require¬ 
ment for 100 pounds of gain is in favor of the pea-fed lots, and that an 
. unusually low amount was required in Lot I, Table III. The pea-fed 
hogs did not display the vigorous appetite at all times that was 
evident in the lots receiving mixed rations. In all cases, the feed 
requirement per 100 pounds of gain was quite satisfactory.
