 NOTICE REGARDING THE INTERSTATE MOVEMENT OP CATTLE, SHEEP, 



AND SWINE WHICH ARE AFFECTED WITH LIP-AND-LEG ULCERA- 



TION (NECROBACILLOSIS). 



UNITED STATES DEPARTMENT OF AGRICULTURE, 



OFFICE OF THE SECRETARY, 

 Washington, D. C., August 10, 1911. 



The attention of managers and agents of railroads and transpor- 

 tation companies, of stockmen, and others interested in the inter- 

 state movement of live stock is directed to the provisions of section 

 6 of the act of Congress approved May 29, 1884, which prohibits 

 the interstate movement of live stock affected with any contagious, 

 infectious, or communicable disease. 



Under this section it is a misdemeanor, punishable by fine and 

 imprisonment, for any person or corporation to deliver for trans- 

 portation, receive for transportation, transport, drive on foot, or 

 otherwise remove from one State or Territory or District of Columbia 

 into another State or Territory or the District of Columbia any cattle, 

 sheep, or swine w r hich are affected with lip-and-leg ulceration (necro- 

 bacillosis), and which by a physical examination show the disease 

 in more than one tissue or lesions of the disease with pus formation. 

 However, sheep which are affected with the mild or inactive form of 

 lip-and-leg ulceration involving the lips or face without evidence of 

 pus formation may be moved interstate, provided the affected parts 

 are immediately before such movement treated with an emollient 

 dressing containing 100 parts mutton tallow, vaseline, or lard, 10 

 parts flowers of sulphur, and 5 parts pure carbolic acid. (In lieu 

 of the carbolic acid three parts liquor cresolis compositus, U. S. P., 

 may be used.) When this treatment is given at public stockyards, 

 where Federal inspection is maintained, it should be done under 

 the supervision of an employee of the Bureau of Animal Industry.

PARASITIC DISEASES. 



GRUB IN THE HEAD ( OESTRUS OVIS, Linn.) 



The parasitic disease of the nostrils of sheep is generally known 

 as grub in the head. The presence of the parasite is not seen from 

 a general examination, only the catarrhal discharge. The grubs 

 are only found on a careful post mortem examination. As a mat- 

 ter of fact, we have very little catarrh of sheep affecting only one 

 side of the nostrils and that usually in late winter and early spring. 

 These supposed catarrhs are nearly always due to the grub stage of 

 the sheep gad fly.
