If two testicles are infected, the ram will be sterile.
Pizzle rot:
This is brought on by a combination of a high protein diet with bacteria. Its medical name is Corynebacterium renale. Corynebacterium renale inhabits either the skin of the prepuce, or the foreskin of the ram's penis.
Corynebacterium renale doesn't cause a problem by itself, but when a ram is on a high protein diet he passes more urea in his urine and the bacteria break down the urea into ammonia. The result is that the ammonia "burns" the area and this causes ulceration. It is painful for the ram, and if things get out of hand secondary problems might be experienced ranging from flystrike to death.
The good news is prevention is fairly easy – just don't feed a diet that is too high in protein. For example, do not feed rams on straight legume hay, rather feed a grass-legume mix of hay.
Whereas minor cases of pizzle rot can be treated with antibiotic ointments, advanced pizzle rot may require antibiotic injects and in some cases surgery.
Ulcerative Dermatosis:
This is a form of venereal disease and can be transmitted by rams to ewes, however the disease is uncommon. This disease can be mistaken for pizzle rot on account of the fact that the early symptoms are somewhat alike. Ulcerative dermatosis most often occurs in the autumn and winter and is triggered when an irritant such as snow ice or cockle burrs damage the skin and allow the virus to enter.
As soon as a ram develops an infection, he should be isolated, overtime the disease runs it course, but the important matter is if the ram introduces it to the ewes, it will circulate through the flock forever.
POSSIBLE DISORDERS IN EWES
During pregnancy and lactation periods the body of a ewe undergoes a lot of stress and problems can occur.
