Ram
|
Balanoposthitis in rams is called “Pizzle rot” or "Sheath rot" .
|
-
The most common infectious form of Balanoposthitis is due to virus that causes ulcerative dermatosis, ulceration of the tip and leg and necrotic venereal disease.
-
The lesion on the preputial orifice, prepuce and glans penis are ulcerative and covered by scab. Removal of the scab reveals a shallow, raw, bleeding crater containing creamy odorless pus.
-
The prepucial lesions may cause phimosis or paraphimosis and an extensive penile lesion may render the ram useless as a breeder.
-
Lesions may also be present on the lip, nostril, feet or vulva.
-
The disease should be distinguished from contagious ecthyma and common non specific lesions occasionally seen on the preputial orifice of rams.
-
Ulcerative dermatosis is spread by ventral contact and other means.
-
In non-infectious forms, two degrees are recognized,
-
an ulceration of the prepuce near the prepucial orifice and a
-
stenosis of the orifice with a secondary chronic ulceration of the deeper portions of the prepuce accompanied by the accumulation of pus and necrotic material.
-
This occurs in wethers or rams of 2 to 4 years of age.
-
It is often associated with a wet spring and pasturing sheep on lush grass,rye, clover or Lucerne that are high in protein.
-
Changing of the diet to dry feed a lower protein intake, or fasting results in an improvement in the balanoposthitis.
-
In sever cases the sheath may have to be surgically opened ventrally to permit urination and the saving the life of the animal.
-
Extending the preputial incision too far caudally may render a ram useless for service. Superficial external lesions may be treated by local therapy.

Boars
-
Balanoposthitis seldom occurs in boars.
-
The preputial diverticulum in boar often fills with foul smelling urine and smegma and externallay may resemble an umbilical hernia.
-
The boar’s sheath may become infested with screw worms.
-
In pigs with hog cholera, ulcers of the prepuce as a result of infarction.
-
Ulceration of the porcine penis due to other causes may be observed. These conditions in boars are usually easily diagnosed and treated.

Dog
-
It is characterized by a discharge of pus from the prepuce and it usually responds well to mild antiseptic douches followed by bland antibiotic ointments or solutions.
|
Balanoposthitis in the dog should be differentiated from the prostatitis as both are characterized by pus appearing at the preputial opening.
|
-
Suppurative ulcerative and follicular balanoposthitis or preputial catarrh is common in the dog.
-
Balanoposthitis in the dog, as in other animals , is due to mixed infections, trauma, foreign bodies, other general diseases and debility.
-
In the dog acquired phimosis is less frequent than is congenital phimosis.

Prognosis
Treatment
-
Treatment of mild cases of balanoposthitis may consist of douching the prepuce with aqueous or oily antiseptics or antibiotic preparations such as saline, 50 to 200 ppm of chlorine solutions, 1:2000 acriflavine or potassium permanganate solutions, 1% hydrogen peroxide solution etc.,
|
Caustic or irritating antiseptics should be avoided.
|
-
Treatments may be repeated at daily to weekly intervals.
-
Regular gentle protrusion of the penis may be desirable to prevent possible adhesions.
-
Tranquilizers, anesthetics, pudental nerve block and adequate restraint are helpful in applying treatment for balanoposthitis.
-
Sexual rest is essential during and for sometime after the treatment of acute balanoposthitis to promote recovery and to prevent a loss of libido associated with painful condition.
-
It may be infectious or noninfectious
