Posthitis in Angora wethers.

M Shelton, C W Livingston

Journal of the American Veterinary Medical Association

|July 25, 1975

Summary

This summary is machine-generated.

Posthitis in Angora wethers is an economic issue linked to a urea-hydrolyzing Corynebacterium sp. Predisposing factors include castration, high protein diets, and infection, causing preputial lesions and urination difficulties.

Area of Science:

Veterinary Science
Animal Husbandry
Microbiology

Background:

Posthitis, inflammation of the prepuce, presents a significant economic challenge in Angora wether goats.
Clinical signs include preputial lesions (scabby or ulcerated) and a distorted or pinhole preputial orifice, leading to difficult urination.
Some affected goats exhibit severe straining to urinate, indicating urinary obstruction or pain.

Purpose of the Study:

To identify the causative agent and predisposing factors of posthitis in Angora wether goats.
To understand the economic impact of posthitis on goat farming operations.
To compare findings with similar conditions observed in other sheep breeds.

Main Methods:

Clinical examination of affected Angora wether goats.

Cultural examination of preputial swabs to isolate and identify bacteria.

Analysis of dietary and management practices of affected animals.

Main Results:

A Corynebacterium sp. capable of hydrolyzing urea was identified as the likely causative agent.
The isolated organism was morphologically and culturally similar to the one previously associated with posthitis in Merino wethers.
Key predisposing factors identified were castration, consumption of a high-protein diet, and infection with the urea-hydrolyzing Corynebacterium.

Conclusions:

Posthitis in Angora wethers is multifactorial, involving a specific urea-hydrolyzing Corynebacterium and environmental/managemental factors.
High protein diets in castrated goats create a favorable environment for the pathogen.
Effective management strategies should address diet and control of the specific bacterial infection to mitigate economic losses.
