Abstract
The evolution of the "big type" hog during the last decade has evidently met the favor of breeders and producers since its distribution has been widespread and its effect on the market rather evident.
The following table shows the changes in weight that have taken place on the Chicago market during the years under discussion.
Since many factors enter into the average weight of hogs in a given year, such as the corn crop, the export demand, the number of hogs on farms, and the financial condition of the country, the above annual averages have been grouped on a three year basis in order to show the trends more definitely. The triennium, 19001902, averaged 226 pounds; 19031905, 223 pounds; 19061908, 224 pounds; 1909é1911, 227 pounds; 1912é1914, 228 pounds; 1915é1917, 214 pounds; and 1918é1920, 234 pounds. Thus far in 1921 the average is 239 pounds. During the first three triennial periods selected, there was little change in the weights, although the average showed a slight decadence.
