What are some genetic disorders in livestock?

What are some genetic disorders in livestock?

Examples of genetic defects include the following:

• achondroplasia (bulldog dwarfism)
• alopecia.
• ankylosis.
• arthrogryposis (palate-pastern syndrome, rigid joints)
• arthrogryposis multiplex (AM, curly calf syndrome)
• brachynathia inferior (parrot mouth)
• cryptorchidism.
• dermoid (feather eyes)

How are skin disorders related to genetics?

Genetic diseases are mainly affecting the skin and its appendages. These are caused by single-gene mutations. Genetic skin disorders are also called as genodermatoses. Nearly forty four skin diseases are there some of them are skin cancer, lupus, acne, psoriasis, hives, warts, carbuncle, and hyperhidrosis.

What causes lumpy skin disease in cattle?

Lumpy skin disease (LSD) is a disease of cattle and buffalo caused by a capripox virus. Since 2012, LSD has spread from Africa and the Middle East into south-eastern Europe, affecting European Union (EU) Member countries (Greece and Bulgaria) and several other countries in the Balkans.

What is osteopetrosis in cattle?

Osteopetrosis is inherited as a simple autosomal recessive trait in Angus and Hereford cattle. It is characterized by premature stillbirth, 10 days to one month prior to term, brachygnathia inferior, impacted molar teeth, and easily fractured long bones.

What are the common congenital defects in cattle?

The number of congenital anomalies was remarkable and included anal and vulvar atresia, hypoplastic clitoral tis- sue, cervical block vertebrae, anotia, brachygnathia inferior, secondary cleft palate, calvarial doming with hydrocephalus and stenosis of the Sylvian aqueduct, high ventricular septal defect, rectovaginal …

How do you treat dermatitis in cattle?

Conclusion

1. Treatment hygiene – using disinfectant to wash hands, equipment and the foot at routine claw trimming or lame cow treatment.
2. Foot hygiene – better scraping, removing sources of deep slurry, water or mud.
3. Foot disinfection e.g. daily 4% formalin foot baths.

What is digital dermatitis in cattle?

Digital dermatitis (DD) is a bacterial disease that primarily affects the skin on the heels of cattle. It is a major cause of lameness in dairy cows and a significant problem for the dairy industry in many countries, causing reduced animal welfare and economic loss.

Is Lumpy Skin Disease curable?

There is no treatment for the virus, so prevention by vaccination is the most effective means of control. Secondary infections in the skin may be treated with Non-Steroidal Anti-Inflammatories (NSAIDs) and also antibiotics (topical +/- injectable) when appropriate.

How long does Lumpy Skin Disease last?

Survival: LSDV is remarkably stable, surviving for long periods at ambient temperature, especially in dried scabs. LSDV is very resistant to inactivation, surviving in necrotic skin nodules for up to 33 days or longer, desiccated crusts for up to 35 days, and at least 18 days in air-dried hides.

What are the most common genetic defects in cattle?

Common Genetic Defects. At the time of birth, alopecia anaemia may be mistaken for hairlessness. Affected calves are often small at birth, have a dirty-faced appearance, and have protruding tongue and eyes. Hair is wiry, tightly curled or absent while wrinkled skin gives the appearance of advanced aging.

Are there any genetic defects in Brown Swiss cattle?

The genetic diseases occur in all breeds of cattle however some defects are strongly associated with certain breeds (‘Weaver Syndrome’ in Brown Swiss). Around 200 different genetic defects have been identified in cattle.

What kind of disease does curly calf have?

Arthrogryposis Multiplex (Curly Calf Syndrome): This disease is generally found in Angus cattle. This defect caused due to autosomal recessive gene. Exact cause of the disease is due to the deletion of a section of DNA (at least 38,000 bp) that encompasses two different genes.

What are the signs of aging in cattle?

Hair is wiry, tightly curled or absent while wrinkled skin gives the appearance of advanced aging. Calves are lethargic, cannot tolerate stress and are very prone to disease. Few survive past six months of age. Malfunction of the skeletal structure results in reduced red blood cell production (anaemia).
