Learn the frightening truth about Fatty Liver Haemorrhagic Disease in hens! Find out how to spot and avoid this dangerous condition before it's too late. Learn more today!
If you have ever seen a chicken, you might have noticed that it has a huge round belly. Much like people, chickens may also get ill. One of the disorders that hens might have is termed Fatty Liver Haemorrhagic Syndrome (FLHS) (FLHS). That is a large name, but we shall explain it to you in simple words.
What is FLHS?
FLHS is a disease that affects poultry, mainly hens. It is a disorder where fat builds up in the liver of the chicken. The liver grows so huge and fatty that it can't perform correctly. This can lead to bleeding in the liver, which can be quite harmful for the chicken.

Description |
FLHS is a
metabolic disorder affecting poultry, characterized by the accumulation of
fat in the liver, leading to hemorrhage, and death in severe cases. |

Etiology |
The exact
cause is not known, but dietary factors, genetics, and viral infections are
thought to play a role. |
4 |
Transmission |
FLHS is not
known to be contagious, but certain factors such as high energy diets and
overcrowding can contribute to its development. |
5 |
Epizootiology |
FLHS is
commonly seen in intensively reared poultry, particularly broiler chickens,
but can also affect turkeys and other birds. |
6 |
Epidemiology |
FLHS has been
reported worldwide and is a significant economic problem in the poultry
industry. |
7 |
Incubation
Period |
The
incubation period can vary but typically ranges from 2-7 days. |
8 |
Pathogenesis |
The
accumulation of fat in the liver leads to impaired liver function, causing
hemorrhage and death in severe cases. |

What Causes FLHS?
There are a few reasons that might induce FLHS in hens. One of the primary causes is when hens consume too much food that is heavy in fat. This can happen if they have access to too much food, or if they are given too many goodies. Another cause of FLHS is when hens are not receiving enough activity. Much like people, chickens need to roam about to keep healthy.
What are the Symptoms of FLHS?
Much as when people are unwell, chickens can also exhibit certain indicators that they are not feeling well. Some of the symptoms of FLHS include:
- Swollen belly
- Lack of energy
- Laying fewer eggs than normal
- Pale combs and wattles
- Dropping weight
If you observe any of these indicators in your chicken, it is crucial to take them to the vet as soon as possible.
How may FLHS be Prevented?
Avoiding FLHS is relatively straightforward. These are some things you can do to make sure your hens stay healthy:
- Offer them a balanced diet that is not too rich in fat
- Make sure they have adequate area to move about
- Give them with fresh water at all times
- Keep their living place clean and dry
How is FLHS Treated?
If your chicken has FLHS, the vet can give them medicine to help them feel better. They might also need to adjust their diet and acquire more exercise. In certain situations, the chicken would need to have surgery to remove the fatty liver.
Differential Diagnosis:
Fatty liver hemorrhagic syndrome (FLHS) is a frequent metabolic illness in chickens, however it overlaps several clinical symptoms with other disorders. The differential diagnosis for FLHS includes:
Infectious Bronchitis (IB): IB is a very infectious viral respiratory illness that affects hens of all ages. Clinical indicators of IB include respiratory signs, such as coughing, sneezing, nasal discharge, and conjunctivitis.
Newcastle Disease (ND): ND is a highly infectious viral illness that may afflict hens of all ages. Clinical indications of ND include respiratory indicators, neurological signs, such as tremors, convulsions, and circling.
Avian Influenza (AI): AI is a highly infectious viral illness that can afflict hens of all ages. Clinical indications of AI include respiratory indicators, neurological signs, such as tremors, convulsions, and circling.
Marek's Disease (MD): MD is a highly infectious viral illness that affects hens of all ages. Clinical indicators of MD include neurological indications, such as paralysis of the legs, wings, and neck, and malignancies in numerous organs.
Fowl Cholera: Fowl cholera is a bacterial illness that affects hens of all ages. Clinical indications of poultry cholera include respiratory indicators, such as coughing, sneezing, and nasal discharge, as well as enlarged wattles and combs.
To discriminate between these disorders, laboratory testing are important. Diagnosis of IB, ND, and AI can be done by viral isolation, antigen detection, and serology. Diagnosis of MD can be done by histology and viral isolation. Diagnosis of poultry cholera can be done by bacterial culture and serology. A veterinarian should be contacted to identify the right diagnostic tests and therapy.
Conclusion
Fatty Liver Haemorrhagic Syndrome is a disorder that can harm hens, but it can be prevented with good care and a balanced diet. If your chicken displays any indications of FLHS, take them to the doctor straight soon. By taking care of your hens, you may help them live happy and healthy lives.
FAQs

Q14.What are the legal and regulatory requirements for reporting and controlling Fatty Liver Haemorrhagic Syndrome outbreaks in chickens
The legal and regulatory standards for reporting and managing FLHS outbreaks in hens differ depending on the country and jurisdiction. Nonetheless, in general, the following criteria should be followed:
Reporting: In many countries, FLHS is a notifiable disease, which means it must be reported to the appropriate government authorities as soon as it is suspected or diagnosed. FLHS, for example, is a reportable disease under the Animal Health Protection Act in the United States.
When a FLHS epidemic is suspected or confirmed, the sick birds should be quarantined to prevent the disease from spreading to other flocks. Depending on the jurisdiction, quarantine protocols may differ, but in general, they involve isolating the afflicted birds and preventing any interaction with other birds.
Treatment: There is no specific therapy for FLHS, although injured birds can be given supportive care to help them recover. This may entail providing safe drinking water and a nutritious meal, as well as supplying medications to avoid secondary illnesses.
To avoid the transmission of FLHS, birds who die from the disease should be disposed of in a safe and suitable manner. This may entail incineration or burial in a designated area in many countries.
Record keeping: Every FLHS outbreaks should be documented, including the number of birds affected, the number of deaths, and any management measures implemented. Government authorities or regulatory entities may demand this information.
It should be noted that these are basic recommendations, and exact legal and regulatory requirements may differ based on the jurisdiction. To avoid the spread of FLHS and maintain the health of their flocks, poultry breeders should be conversant with their local legislation and standards.
