other animal feeding, the fertility now in some districts largely lost 

 to the farms of Idaho by shipping bulky crops to distant markets. 



Our forest reserves and other mountain pastures are rich and of 

 high fattening value. Many of our sheepmen find that the bigger and 

 more thrifty lambs come from these pastures in the fall quite fat. 

 Such lambs are cut out and shipped to market as grass-fattened. 

 Under present conditions it is probably wise practice to ship a large 

 percentage of the fattest lambs. In a large number of cases, however, 

 the sheepman's and the packer's ideas as to the proper finish for lambs 

 ready to kill do not coincide, and a large portion of the lambs shipped 

 as grass-fed are cut back to be sent to the country for a 50 to 90-day 

 feeding period in eastern feed lots. This fact is clearly proven by Bulle- 

 tin 162 of the Purdue Experiment Station, a 40-page publication re- 



Shropshire ewes owned by Knollin and Finch, Soda Springs, Idaho. 

 Large flocks of pure bred sheep are pastured on Idaho summer range. 



porting results in feeding 420 lambs, all of which were Idaho bred 

 lambs, purchased as feeders in the Chicago market. In this state we have 

 more sunshine, drier feedlots as a rule and less shelter is required as 

 compared with feeding conditions in the central states. Such lambs 

 as above mentioned should be kept in Idaho until properly finished 

 on home-grown feedstuffs. 



The cutting out process on the range leaves behind a large num- 

 ber of thin lambs of various sizes, that can be most profitably marketed 

 when fat. It is the last named class of lambs that have been used 

 in the lamb feeding experiments hereafter described.
