There is no medicine to control prolapse in laying hens. This is a management problem caused by having poor uniformity, small framed and underweight birds, stimulating to early for egg production before birds have attained their correct body weights and size. Prolapse is the result of these birds forcing to lay large and extra large eggs for which their body frame is not ready to produce.
As far ...

Prolapse in layers is of concern when birds are either underweight at time of changing from a growing ration to a prelay and then a laying ration. Birds that have a small frame due to underfeeding during the growing phase, and poor uniformity. Overcoming these factors means paying more attention to body weight and uniformity. A good guide is the management guide produced by the breed company you a ...

Dr Mahbub, what strain of bird are you using?

Hi Me-navid, at 28 months of age(112 weeks) and 80% production, your birds are doing well. They are still overweight but at this age, and the fact you are feeding more feed than required due to the increased body weight, you now have to ask yourself the question as to whether you should keep these birds in the production cycle, or should moult them and bring them back into production, or terminate ...

Hi Me-navid, is your flock 28 weeks of age or 28 months? Please clarify, as you initially said they were 28 weeks of age.

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 prod ...

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 producti ...

The simple answer to your question is yes. However, with broilers, it is more normal to have chicks placed as straight run where males and females are reared together. This can pose some problems if you are very particular about feed type and management and age at which the birds are "pulled" for sale. The second way broilers are raised, male and female chicks are separated at the hatchery and pl ...

I agree this is not always possible especially when the flocks are large. However, in developing countries broiler breeder producers may not be as large as those found in North America so dividing the barn and sorting of birds into small, medium and large birds with a small area for males is not difficult. When we started this program the farm was raising 15,000 broiler breeders, but divided betwe ...
