PROLAPSE IN POULTRY

PROLAPSE in poultry is a condition whereby the oviduct (uterus) comes out during laying and does no invert back. It is also referred to as Blow out, cloacal prolapse or pick out.

 

CAUSES  OF PROLAPSE:                                                                      

Many factors has been fingered. Some of which are:1.Over weight bird

2.underweight bird

3.Improper photo stimulation

4.unbalanced diet

5.Infections (E.coli, Salmonellosis,Klebsailla) 

6.Mycotoxicosis

7.Worms

8. Coccidiosis

9.Ectoparasites

10.Overcrowding

PREDISPOSING FACTORS OF PROLAPSE

First indication of prolapse is presence of blood stained egg and or double yolked lay of more than 4% in older laying flock. Prolapse can affect young  and old layers.

COMMON OBSERVATION IN PROLAPSE CASES.

1. Birds are overweight or under weght

2. Protruded oviduct after laying

3. There is cannibalism

4. Cannibalism

5. Increase noise in the flock particularly during cannibalism

6. Jumbo eggs usually blood stained

7.  Increased mortality.

TREATMENT OF PROLAPSE

Treatment of prolapse is quite complex involving a lot of adjustments. The best is to prevent its occurrence. Some treatment tips are:

1. Reduce the feed intake by 5-10% if the birds are overweight.

2. Adjust the ME (metabolizable energy) of the feed to the minimum requirement.

3.Adjust the light exposure time of the birds reducing it to 12h for 1to 2weeks before gradually increasing it 1 hr per week til the max 16h.

4. Light intensity should be recuse I.e reduce the brightness. In some cases, red bulb light are used to reduce cannibalism.

5.Apply liver tonics such as SUPERLIV to aid in liver metabolic function.

6. Choline chloride is useful too for fat depletion.

7. Broad spectrum antibiotics is needed in cases of infection.

PRECAUTION/ PREVENTION OF PROLAPSE

1.Monitor the growth of pullets particularly to attain the standard weight from WK 5 to WK 8.

2.Ensure normal light  intensity during the growing phase.

3. Commence photo stimulation  when the birds  reach 1.25 - 1.3kg irrespective of age.

4. Give more calcium in the feed of layers at peak production (2.5 - 3.5%).

5. Ensure good management practice to keep infection at bay.
