Prolapse in hens . Prolapse is a disorder of the laying hen caused by poor body development, lighting, intestinal diseases, among others.
Characterization
During the last years in poultry farming , the strong incidence of prolapse and pecking has been handled on a daily basis, and the consequences that this implies for productive compliance can be seen with the naked eye, bringing as a consequence great economic losses. The complete prolapse of the hen is, simply, the excessive emergence of the oviduct, together with the eversion of the rectal organs through the orifice of the cloaca , in such a way that it cannot be retracted to its normal position. Actually every time the hen lays an eggphysiological prolapse occurs. It is described that the oviduct becomes a problem only when there have been rearing or management problems that have interfered with the normal ability of the hen ‘s body to resist the stress of laying.
The prolapse almost always seems to occur along with another condition called itching. Prolapse frequently occurs as a result of repeated severe pecking at the cloacal orifice area or discharged oviduct of a cagemate immediately after laying her egg . Repeated pecking attacks damage the structure of the oviduct and it eventually fails to retract, and the bird may die. These two conditions, pecking and prolapse are referred to together as Non-Specific Prolapse and are among the most common causes of loss mortality in cage layer operations under a wide variety of environmental and management conditions throughout the world.
Through the clinical inspection of each bird and the morphological characteristics that result from the prolapse, taking into consideration that this is verified with the exit of a viscera or organ from the cavity that is normally found through natural openings to the outside and that occurs At the moment in which the hen begins oviposition and her reproductive system performs a physiological prolapse of the oviduct, where an inversion of the organ occurs in a few seconds and the egg is deposited, returning to its place for its next laying.
Young hens, especially if they are fat, are susceptible to prolapse when their oviduct does not retract after egg is laid, which induces pecking of the cloacal area. It can even lead to the exit of intestines.
Use of Green Medicine
There are several options to treat prolapse, among them green medicine plays an important role, since there are several plants that are used for this purpose, among them we have blackberry and aloe vera , which have shown great effectiveness. Aloe vera has anti-inflammatory, antibiotic, detoxifying, rehydrating and healing actions, hence its widespread use in both human and veterinary medicine , and particularly in birds.
The aloe vera preparation is made by collecting 300g of the plant daily, proceeding to wash it, subsequently extracting the shell, beating the crystals until a transparent white cream is obtained. The cream obtained was applied topically to the affected birds for 7 days in the morning, after trimming the vent feathers and washing the region with boiled water.
It is very important to bear in mind that if there is no correct vaccination regimen for the birds, if inviolable management conditions are not maintained, if a correct biosecurity program is not followed, the breeding will not comply with the established production parameters. The correct management of layers is the best way to prevent prolapse, its proper application could help to reduce the severity of the situation as much as possible.
