Abdominal eggs
-
Abdominal eggs affected birds are known as internal layers, may be due to reverse peristalsis or rupture of the oviduct.
-
Affected birds may be found dead with out showing any signs.
-
Other birds may show abdominal enlargement.
-
Surgical removal of egg via abdomen is advisable if egg peritonitis is not formed.
Egg peritonitis
-
Affected birds may show sudden death, depression, weight loss, respiratory distress.
-
In advanced cases peritoneal adhesions may also noticed.
Egg binding
-
It is due to obstruction or impaction of the vagina with fully formed egg.
-
The factors associated with this condition are obesity, over sized eggs, low blood calcium, poor muscle tone, nervousness, variation in temperature and lack of suitable nesting place and poor body condition.
-
Clinical signs are intermittent bouts of straining, adopt abnormal postures
-
Treatment: recent egg binding can be treated by keeping the bird in warmed cage preferably with infrared irradiation, lubrication of cloacal opening, placing the bird in steaming kettle.
-
If the egg is in the vagina the content can be removed by hypodermic syringe and needle.
-
Injection of calcium gluconate to Budgerigars showed some success.
-
Oviduct prolapse
-
Usually restricted to laying birds. Sub optimal diet, and birds kept in small cages that have not laid an egg for a considerable period of time.
-
Affected birds are often bright and alert and condition not noticed.
-
Recent prolapse can be treated surgically, if egg is retained can be removed and the prolapsed materials can be surgically retained and sutured.
-
But it cannot prevent subsequent egg formation, which may complicate the surgical intervention.
