Fully agree! My own experience also suggests that the main reason for prolapse these days is underweight birds! Managing body weights and uniformity in the flock at sexual maturity is very crucial in avoiding prolapse and attaining peak production!

Dear Dr. Beny Perelman
DVM, Specialist in Poultry Diseases and Management, Ostrich Medicine Exper

Excellent, you have rightly pointed out the root cause of prolapse.
However, to some extent it is genetics too, In south India, it is very rare to find Bovans flocks in recent years because the incidence of prolapse is high in Bovans when compared to other lines such as BV 300 or Lohman or Hyline.

In case of prolapse rule out avian influenza. Cloacal lesion is one of the typical lesion of ai. From dead birds, you can screen rectum for streaks of hemorrhage. Collect pancreas and make 50 percent extract with saline. Centrifuge. Collect supernatant and do ha test. If the sample shows ha activity with addition of nd antiserum to pancreas extract. Even with d antiserum, the sample shows ha activity then sample is positive for ai. On the contrary, it shows inhibition means sample is positive for nd.

Athangudi Venugopalan it is very good point, but why by pancreatic supernatent?

Good information to prevent prolapse by management tool in modern laying birds.

Standard Light duration of 15 hours, controlled body weight and uniformity is to be considered.

What's the actual developmental time of reproductive tract of laying hen? Which nutrients play major role to it?

"The participation of Dr. Danka, I believe, is the most appropriate in the context of a good management policy, since what the other parties (whose opinions are correct and valuable, of course) mention, they adapt to the conditions multifactorially established a priori through various studies (adjustments of the photoperiod, assertive choice of the germplasm, etc.).
 
Some of the recommendations of the Dra referred to above, must be taken into account, specifically in relation to the reduction of the energy level (EM) in the concentrate, in about 10%; in the period of higher microenvironmental temperature, because this will reduce caloric stress, manifested in a nervous state of the bird that promotes pecking / cannibalism; especially in the anal and / or perianal area (one of the causes of cloacal prolapse). This I have been able to verify when I worked in the breeding line that showed some excess weight (Lima-Peru).
In addition, I consider that the use of BETAINE (Anhydrous or HCl), where the osmoregulatory function is equally effective, is recommended as being one of the most effective, especially in summer, to mitigate (not the panacea) the sequelae of caloric Stress.
Finally, given the concern of the person who opened the forum, I would like to say that once the cloacal prolapse manifests, there is NO effective therapy to reverse the situation. Rather, yes, a successful preventive policy, among which is the use of aloe (Aloe vera), where the cream obtained is applied topically in the birds affected by snacking during 7 days of the morning. Its effectiveness is also evident in semi-prolapsed birds. Greetings from Peru."

From my practical point of view, I actually agree with the fact that reduction in the energy content will go along way in preventing the problem. Where it is seen in a lot of the birds, Choline chloride is also effective in fat burning. Reduction in the quantity of feed as well as adjustment in the time of feeding are also very important. Commercial layers can be fed during the cool hours of the day like 0700 hours and 1700-1800 hours. Reduction in energy content will require the input of an expert so as not to compromise other nutrients.

Prolapse is a condition that arises in young layers as a result of many complex reasons during growing age. Managemental practices, lighting, feed quality, nutrition and body weight at the time of point of lay, are the few key factors which predispose the condition... prolapse. In birds which are in peak or going to peak, any changes in feed and nutrition may affect the production.

Severe form of lPAI is widely prevalent. cloacal lesion and prolapse is common among layers, as on date without control of low pathogenic avian influenza control of prolapse of cloaca is difficult.

The phenomenon is obvious in layers where production is higher and the feed value is less than the hen physiological requirement with other management factors.

According to the latest Bovans layer management guide, at 23 weeks of age the birds should be around 1.7 kg. This is about 200 grams heavier than your birds at 1.5 kg. Light stimulating birds to bring them into production when they are underweight can cause prolapse. I would suggest that you contact your nutritionist and let him reformulate your ration to suit the weight of the birds, egg production and egg size. The objective is to reduce the egg size so that the birds are not trying to lay large or extra large eggs. Once you start this program you will need to work very closely with your nutritionist and feed supplier so that the birds don't stop laying. Don't interfere with the lighting program as this will shut the birds down, unless you want to do so and bring them back into production.

Robert Huggins, Sir.

Is it applicable to Indian conditions also? If yes, then what will happen to the shell quality post peak laying. Where in culls are sold at 1550 to 1600 GM's in cage layers in India.

Also, will it affect hen housed eggs? If not, why
Kindly explain as India is large egg producing country and eggs are sold In numbers not in GM's.

I am manager of laying farm with 60000 bird. Daily mortality is 5 to 8 birds. Usually, 3 birds regard to prolapse lesion. Herd age is 28 month. Energy level ration is 2740 kcal and cp 14.5 %. Egg weight is 68 grams. Live weight is 1700 grams. Herd breed is Hyline w36.
Are these situations worrisome?

W36 is a small bird and the egg size is very high, it does not surprise me that you see prolapse.
At what age you will change the flock ?

Éric Dion Thanks for answer. My herd is 28 month. The herd molted in 80 weeks.

We need to differentiate between prolapse and pullouts.
The prolapse is common in early matured birds with more body weights. I concur with the opinion of Dr. Robert Huggins, nutrition plays a main role in the conformation of body weights. Secondly, the egg size: the rupture takes place in pushing large or double yolked eggs.
Thirdly, it is common in cage laying units, Where the idle bird pulls or damage the cloaca of egg-laying bird, pulling out all the visceral parts and develop it as a vice, there will be more mortality with improper debeaking also.

DR.R.N.Sreenivas Gowda I Would Suggest You cull and beak trim properly to cater for the latter point

Early matured birds with more body weights may be due to nutritional imbalances or light intensity

Hi Me-navid, looking at the target weights and egg production for HyLine W36 layers at 28 weeks of age I would say yes, you may need to be concerned as these birds are over 200 grams more than the guidelines suggest for 28 week old birds. Although I don't like to see birds that heavy above target weights, 50 to 100 grams is acceptable and you will have to maintain these weights throughout the production cycle. However, if the birds are stimulated to early at these weights large and extra large eggs can be obtained but remember these birds are still young, and their bodies have not fully matured as yet which can result in prolapse. The feed you are presently using containing 2740 kcal/kg and 14% protein is the suggested requirement for the Layer 5 ration, recommended by HyLine for birds producing less than 80%. If this is your production level at 28 weeks of age, you definitely have a problem and you may need to have your nutritionist have a look at your ration, and your poultry Vet to see if there any underlying problems that are causing your daily mortality. What is your present production?
