FAT-RLMP RAMBOUILLET LAMB 



The first product of the attempt at the South Dakota Agricultural Experiment Station to breed 

 a valuable type of sheep that will flourish in deep snow. This lamb was two and one-half 

 months old when photographed. The tail is somewhat reduced in size from that of the 

 maternal (Rambouillet) stock, and it is hoped to get rid of it altogether, and substitute a 

 development of fat as in the paternal stock. (Fig. 13.) 



on the form, size, vigor, production, etc., 

 using Jerseys and Holstein-Friesians. 

 Creation of new breeds of sheep for 

 the semi-arid conditions of the north- 

 west has been undertaken by the South 

 Dakota station, with the fat-rump sheep 

 which N. E. Hansen brought back from 

 Turkestan last summer. They will be 

 crossed principally with the Down 

 breeds. "We have the first crossbred 

 lamb of this breed." Director James W. 

 Wilson reports, "and I do not believe 

 there is another sheep in the United 

 States exactly like it. I intend to 

 eliminate the tails in the crossbreeds 

 and increase the development of the 

 rumps so that the new breeds will be 

 able to withstand the deep snows that 

 we get frequently in the winter time on 

 the range, when sheep can not get 



anything to eat. At this time they will 

 live on the fat stored up in their rumps. 

 These sheep came from the home of the 

 camel and are noted for their endurance 

 of hardships." Observations are also 

 being made on the relation of feed and 

 care of parents to the condition of 

 offspring. 



A NEW BREED OF FOWLS 



Rather striking success has been 

 produced in the Rhode Island station's 

 study of inheritance in poultry. "The 

 aim of this study has been to produce 

 ' barring ' as a result of crossing pure-bred 

 black with pure-bred white fowls; and 

 then to ascertain whether the manifes- 

 tation of barring can be accounted for 

 by any known methods of inheritance." 

 A barred race has actually been pro-
