110 BIENNIAL, REPORT OF DEPARTMENTS OF AGRICULTURE 



Necrobacillosis 



The noncontagious form of this disease, commonly known as foot 

 rot, is rapidly becoming more prevalent in Kentucky sheep. This con- 

 dition has formerly been considered one confined to low, swampy land. 

 However, during recent years it has become very common in hill lands. 

 It has also taken on many characteristics of a communicable disease 

 and does not respond readily to treatment. While the mortality is not 

 great, the economic loss is very heavy. The treatment, to be success- 

 ful, must include the entire flock and must be continued for some time 

 after all symptoms disappear. Our work in this field, while rather 

 extensive, has been largely along educational line. If the farmer can 

 be sufficiently impressed with the danger of this disease, and the im- 

 portance of systematic treatment, the financial loss may be reduced 

 and the disease controlled. Otherwise, some regulatory measure will 

 be necessary. 



Lip and Leg Ulceration 



This form of the disease, while widely distributed throughout the 

 United States, is seldom found in Kentucky, except in sheep shipped 

 in from out of the state. 



This office receives numerous calls on outbreaks of this condi- 

 tion. However, its control causes little concern as it responds readily 

 to treatment. 



Internal Parasites 



The stomach worm is by far the most important in this class. 

 Doubtless, there are few flocks in Kentucky free from this parasite, 

 and the economic loss resulting would be impossible to estimate. 

 Efforts in this field have also been extensive, but of an educational 

 nature. 



SWINE 

 Hog Cholera 



Reports indicate that cholera has been more prevalent during the 

 last half of this Biennial, than during the years just previous. This 

 condition is largely due to failure to vaccinate on the part of the 

 farmers, especially is this true where exposed hogs are bought at local 

 stock yards and taken to the farm. Little danger exists that cholera 

 will ever reach epidemic proportions in those parts of Kentucky that 

 are accessible to graduate veterinarians. Since the serum-virus vacci- 

 nation, in qualified hands, has proven almost 100% preventive and 

 immunization at the proper age is so inexpensive, little sympathy is 

 due the farmer that sustains losses from cholera. 



Principally all the work done with swine by the Cooperative Forces 

 is in the mountains and other sections of the state not in reach of a 

 graduate veterinarian.
