674 EXPERIMENT STATION EECORD. 



gain on the narrow ration was 2.26 cts. and on the wide ration 

 2.01 cts. 



The value of different breeds for dressed pork and bacon is dis- 

 cussed, many statistics of the export trade of pigs and the manufac- 

 tured bacon being given. Considering the average cost per pound of 

 gain before weaning, the breeds ranked as follows: Yorkshire, Tam- 

 worth, Poland China, Chester White. Berkshire, and Duroc Jersev; 

 considering the average cost per pound of gain after weaning: York- 

 shire, Poland China, Duroc Jersey, Berkshire, Taraworth, and Chester 

 White. The Yorkshires gave the largest dressed weight in proportion 

 to weight before slaughtering, being followed by the Poland Chinas, 

 Tamworths, Chester Whites, and Berkshires and Duroc Jerseys in the 

 order mentioned. As regards the total value of cuts in carcasses, the 

 breeds ranked as follows : Yorkshire, Tam worth, Poland China, Duroc 

 Jersey, Chester White, and Berkshire; as regards quality of meat, i. e., 

 a satisfactory mixture of fat and lean, they ranked as follows: Tam- 

 worth, Berkshire, Chester White, Duroc, Poland China, and Yorkshire. 

 The Tamworths were considered most suitable for export trade, the 

 Yorkshires least so, while the Berkshires, Chester Whites, Durocs, 

 and Poland Chinas ranked next to the Tamworths, in the order men- 

 tioned. 



In connection with one of the tests reported above, extended chem- 

 ical studies of the composition of the Hesh of the different breeds were 

 made b}" the Division of Chemistry of this Department (E. S. R., 

 10, p. 877). 



"While the testimony of these experiments is most strongly directed toward 

 emphasizing the necessity of securing the right type of a hog as represented in the 

 bacon breed, yet the results show that the question of feedmg is one of equal 

 importance. ... It was very manifest that the feeding of a wide ration or one rich 

 in carbonaceous materials resulted in a carcass excessively fat, while the feeding of a 

 naiTow ration, or one rich in nitrogenous materials, made a carcass containing more 

 or less meat or muscle. [?. c, type for bacon.] 



.... "If a division of this industry into the raising of bacon hogs as well as the 

 production of lard pigs is brought about, so that the 2 types are distinctly recognized 

 in the market, it would seem very evident that it would materially help the price of 

 the lard hog. The creating of a demand for a new product would necessarily lighten 

 the competition in the other direction, which it is natural to suppose would result in 

 stronger prices. Instead of desiring to check the development of bacon production 

 it would seem the best policy for the hog breeder to try and encourage it by produ- 

 cing the type and feeding for the purj^ose of satisfying the bacon market." 



Poultry experiments ( Utah Sta. Bui. 67., pj). 121-159., j?^-^- ^)- — 

 Continuing previous work (E. S. R., 11, p. 480), tests are reported on 

 the relative value of pullets and hens, early and late hatched pullets, 

 and the effect of exercise on egg production. The feeding value of 

 corn, dried blood, and sunflower seed as a part of the ration was also 

 tested. The test began with 1.5 lots of 5 pullets or hens each and 

 covered 1 year. The breeds used were Leghorns, Wyandottes, and 

 Plymouth Rocks. With the exceptions noted, all the lots were fed
