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.
 Prolapse is a very serious condition that can be treated if caught early, but is likely to recur.

Prolapsed cloacae
Unable to invert cloacae


CAUSES  OF PROLAPSE:                       
1.Obesed older chicken
2. Birds laying when too young
3.Improper photo stimulation
4.Unbalanced diet like calcium deficient diet
5.Infections (E.coli, Salmonellosis,Klebsailla)
6.Mycotoxicosis
7.Endoparasites (worms)
8. Coccidiosis
9.Ectoparasites
10.Overcrowding can lead to pecking

 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.

PREVENTION OF PROLASE
1. Adhere to strict biosecurity on the farm

2.Monitor the growth of pullets particularly to attain the standard weight from  week 5 to week 8

3.Ensure normal light  intensity during the growing phase.

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

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

6. Ensure good management practice to ward off infection

7. Ensure that any young hens who aren’t ready to lay eggs are not exposed to artificial light. This can cause the hens to start laying eggs before they are physically meant to.

TREATMENT OF PROLAPSE
1. Isolate affected bird from the flock
2. Clean protruding tissue with veterycyn
3. Replace tissue manually and spray veterycyn 2 to 3times per day
4. Apply anti-inflammatory cream like hydrocortisone
5. Reduce the feed intake by 5-10% if the birds are overweight.

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

7. 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.

8. Light intensity should be reduced. In some cases, red bulb light are used to reduce cannibalism.

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

10. Choline chloride is useful too for fat depletion.

11. Use broad spectrum antibiotics in cases of infection.
