Causes of Vent Pecking, Prolapsed Vent and Cannibalism among Poultry Birds

Causes of Vent Pecking, Prolapsed Vent and Cannibalism among Poultry Birds

Some farmers witness the intestines coming out and pecked as they lay but many times, the farmers decide to suffer in silence because of not knowing the cause or the problem or how to resolve them and sometimes we blame a particular breeder that their birds peck too much.

Let’s take a look at some of the facts about the cause of the problems:

1. Wrong regulation of growth of the birds during the grower phase. You should not force the birds to lay when they are still young. It’s very bad. 18 to 20 weeks is safer to start laying than 16 or 17 weeks

2. Too much boosting of the birds; the so called egg boosters and heavy vitamins that you always supplement your birds have a lot of nutrients which many times make the eggs very big to an extent that the birds small vent cannot handle.

The premix you have in the feed is enough to give your birds good and well balanced vitamins. Let no re-marketing vets mislead you into egg boosters

Too much of egg boosting on these starting layers will burst their behinds.

3. Mineral imbalance
Dealers of concentrates are fighting hard to have their formulations cheaper than the other competitors, so many times they have ended up with imbalance of minerals in the complete feed.
Among these minerals is the calcium.

Inadequate calcium in feed leads to weak bones, weak eggshells, cage layer fatigue, more damages in eggs and weak muscles
The muscles that hold back the vent after laying become weak and just leave the vent out, so exposing the vent to being pecked by other birds.
Add good quality lime in feed, in its rightful amounts in the feed. Do not adulterate your feed with excess broken maize too.

Lime ( preferably white lime) is readily available calcium for utilization. So it puts less burden on the intestine during digestion and works faster than shells. White and granulated lime are more pure than shells.
Shells have to go under serious digestion to get out the calcium. Shells carry a % of sand so you will need a bit more shells than lime dirty shells too can be a cause of disease.

4. Heat Stress
At one farm, the birds lost feathers and remained naked simply because they had a lot of heat from the roof! The house was too short, and this problem used to happen only during the dry season.

So, because the behind of the birds was naked, these other birds could easily see the vent coming out as the bird lays the egg and they started pecking even after laying, these birds as they try to prick off the feathers in a way of cooling their bodies from the heat, a little blood came out which attracted other birds to peck.
Plan the houses very well! With proper ventilation.

5. Debeaking
I do not have mercy on beaks. Even if it leads to too much pain, I have to cut off the beaks using this pair of scissors or automatic machine (looks like a pruner but a bit smaller).

Debeaking should always be done right, by the right person, at the right time( 10 to 12 weeks) and handle the stress after debeaking using an active multivitamin.

6. Design of laying boxes.
Your laying boxes should be properly covered to give enough darkness when the bird is laying otherwise if it’s very exposed by too much light, these birds will easily peck since they see other’s behind when they are laying.

Try to place the laying boxes in a dark place, not direct in the sun or where there is a lot of light.

Supplement your birds on multivitamin to control stress after debeaking, after vaccinations, deworming, transportation ( brooder) and all other kinds of stress.
