breeds. Were as many animals included as there are of the Short- 

 horns, for example, they would no doubt rank lower in the list. 



By the last column of the table we learn that steers of the beef 

 breeds yielded from 64 to 65 per ct. of dressed carcass, while those of 

 the dairy breeds and the natives dressed only 60 to 63 per ct. Eleven 

 Herefords fattened and slaughtered at 4 stations yielded 8 per ct. 

 more dressed carcass to live weight than did 9 natives at 3 stations. 

 The weights of the native and dairy-bred steers are so large as to in- 

 dicate that they were as mature and as well fattened as their com- 

 petitors. Here is the first marked difference in favor of the beef -bred 

 over other cattle for beef production. 



517. Loose tallow. At the Iowa Station 1 Wilson and Curtis* 

 found the quantity of fat about the internal organs of fat steers of 

 the various breeds to be as shown in the table below: 



Weight of carcass and loose tallow of steers of various breeds. 



It is shown that the Short-horn steers, dressing about 1,100 Ibs. 

 each, yielded 145 Ibs., or 13 per ct., of loose tallow, while Jersey 

 steers averaging 880 Ibs. yielded over 165 Ibs., or 18.8 per ct. These 

 figures are corroborated by similar findings at the Michigan 2 and Mis- 

 souri 3 Stations. Commenting on the character of the carcasses of the 

 various breeds slaughtered at the Michigan Station, Davenport wrote : 

 ''Note the excess of rough tallow in Walton (a Holstein steer) as 

 compared with the others. Walton was 'all cow,' as the saying goes, 

 and the fat about his kidneys was astonishing. ' ' 



From these data we may conclude that there is a specific difference 

 between the beef and dairy breeds in the distribution of fat within 

 the body. It appears that the beef representatives place more of the 

 fat between the fibers of the muscles. On the other hand, steers of 

 the dairy breeds deposit proportionately more fat about the intes-
