Durinjr the year, outbreaks of mange — first 

 thoiipht to be psoroptic cattle scabies — were 

 reported from Alabama, Oklahoma, and 

 Wyoming. 



Chorioptic mange was also reported from 

 Oregon. The outbreaks occurred in two flocks 

 of sheep in Benton County and in three herds 

 of goats in Clackamas and Lane Counties. 



The situation in cattle scabies 



Psoroptic cattle scabies was reported in a 

 large feedlot in Weld County, Colo. ; a dairy 

 herd in ^Marshall County, Ind. ; a feedlot in Pot- 

 tawattamie County, Iowa ; and a ranch in 

 Baker County, Oreg. Infected and exposed 

 cattle were treated, and an effort was made to 

 locate the source of the outbreaks. 



In November 1959, mites were found in a 

 shipment of four bulls and one cow trucked to 

 the Ogden Union Stockyards in Utah from Sub- 



lette County, Wyo. Specimens submitted to 

 the Utah State University and to the ADE 

 Diagnostic Laboratory were identified as sar- 

 coptic. Additional infected animals were found 

 in the Sublette County herd and on adjacent 

 ranches. An eradication program was started 

 immediately. The disease may have been pres- 

 ent in the area for some time. 



The Bureau of Land Management cooperated 

 b\' refusing entry of undipped cattle from quar- 

 antined areas to lands administered under the 

 Taylor Grazing Act. A State quarantine was 

 placed on a large area in Lincoln, Sublette, and 

 Sweetwater Counties. Additional inspectors 

 from Colorado, Nebraska, Texas, and Utah 

 were assigned to assist in the eradication ef- 

 fort. 



Inspection of all cattle in the quarantined 

 area — about 14.5.000 — revealed infection in 14 

 herds. Cattle in all herds in the quarantined.
