however, never be fed alone, and should always be ground. Pigs 
fed on pea meal alone do not thrive, do not get fat, and produce a 
very inferior quality of meat, dry and hard.' 77 Peas, largely in the 
form of meal, have a rather important part in hog feeding in Europe 
where bacon production is a specialty. 
PURPOSE 
The purpose of this investigation is to study the quality of pork 
produced from field peas exclusively and compare it with pork 
obtained from pea-barley, barley-tankage, and corn-tankage rations, 
from the standpoint of shrinkage in the curing processes, melting 
ponts, and iodine values. 
PLAN 
Two methods of feeding were adopted. In part 1 the hogs were 
confined to the dry lot. In part 2 a preliminary forage period 
preceded the dry-lot feeding. 
PARTI 
Thirty-two thrifty, uniform, Duroc-Jersey shotes, averaging 120 
pounds, were divided into 4 lots, and fed for 76 days (February 23 to 
May 9, 1923), on the following rations: 
Lot I, cracked peas alone. 
Lot II, cracked peas 3, barley 7. 
Lot III, rolled barley 15, tankage 1. 
Lot IV, cracked corn 9, tankage 1. 
In addition to these rations, all lots received, with the evening 
feed, 2 pounds of the following mineral mixture: 100 pounds bone 
meal, 100 pounds charcoal, 50 pounds common salt, 50 pounds 
sulphur, 25 pounds copperas. 
PART 2 
Forty-six well-developed, uniform, Poland-China and Duroc- 
Jersey shotes, averaging 98.5 pounds, were divided into 4 lots. A 
forage period of 30 days was introduced prior to the dry-lot feeding, 
according to the following plan: 
Lot I, hogging-off, 0.85 acre peas. 
Lot II, hogging-off, 0.95 acre peas, and in addition a 1 per 
cent ration of rolled barley. 7 
Lot III, alfalfa forage and a full ration of rolled barley 15, 
tankage 1. 
Lot IV, alfalfa forage, and a full ration of cracked corn 12, 
and tankage 1. 
Feeding was then continued in the dry lot, as follows: 
Lot I, cracked peas alone. 
Lot II, cracked peas 7, rolled barley 2. 
Lot III, rolled barley 14, tankage 1. 
Lot IV, cracked corn 10, tankage 1. 
7 Eleven hogs were used in lots I, III, and IV. Two additional hogs were used in lot II in order to hog 
off the peas at the same rate as in lot I.
