the smaller breeds will reach their limit 

 of growth at about this age. 



Popularity op different breeds — 

 Some idea of the popularity of the dif- 

 ferent breeds can be obtained from the 

 number of pure bred animals registered 

 in the different associations and which 

 are now alive. In 1905 the figures for 

 the Poland-Chinas were 113,000; for 

 Berkshires, 30,000; Duroc-Jerseys, 20,- 

 040; Chester White, 8,400; Yorkshires, 

 4,600; Essex, 1,300; Victorias, 1,200; 

 Tamworths, 1,200; Cheshires, 1,000; 

 Hampshires, 500. 



These figures indicate that the Po- 

 land-Chinas are much in the lead, fol- 

 lowed at some distance by the Berk- 



ing surpasses all others in good qualities. 

 The experiment stations of the country 

 have secured good representatives of the 

 different breeds and have made exten- 

 sive observations and tests to determine 

 which breeds can be fattened for market 

 most economically. Rommel has sum- 

 marized the data secured at the Maine, 

 Vermont, New York state, Michigan, 

 Wisconsin, and Iowa experiment sta- 

 tions, and the Ontario Agricultural Col- 

 lege and Central Experimental Earms 

 in Canada, with reference to the feed 

 required to produce 100 pounds of gain. 

 The data are given in the following 

 table :

shires, the Duroc-Jerseys and Chester 

 Whites. The Poland-Chinas are partic- 

 ularly satisfactory to hog growers in the 

 corn belt. Outside of this region they 

 are no more popular than a number of 

 other breeds. In the South, the Berk- 

 shires are probably most popular and 

 numerous. 



So far as can be learned, there is no 

 special market and no special demand 

 by packers in this country for bacon 

 breeds of hogs like the Tamworth and 

 Yorkshires. These breeds sell as well 

 on the market as any other, but do not 

 bring any higher price at present. Ow- 

 ing, however, to the large proportion of 

 lean to fat in the carcasses of these hogs, 

 the pork is superior and these breeds 

 are likely to increase in popularity. 



Test of breeds — Swine growers and 

 breeders have their favorite breeds of 

 hogs and believe that in their hands the 

 particular breed that they are rais-
