Newcastle Disease Treatment
Newcastle disease treatment is a mysterious idea for any veterinarian and others. Although, there is no specific treatment of NDV. Prognosis is varied species to species and time-consuming. nevertheless, It is considered to be the most economical also because of poultry can not reach previous production volume.
Background Of Newcastle Disease Treatment
But, It has been sometimes done for saving the birds and economical loss of the farmers. Therefore, It is a regular practice where the government does not provide financial support to the farmers after losing their birds. Although the first world countries cull the birds of the Newcastle disease affected farm by the giving compensation or other national policy.
But in the thirds world country especially south again origin, there is no compensation facility available. So, the treatment of Newcastle disease is my regular working scheduled and has lots of experience I have. In some cases, farmers are protected by the extreme business fall down and continue the farm operation for several years. Because of, Newcastle disease recovered birds showing life long immunity throughout their life.
The ultimate way of Newcastle disease Treatment
There are three considerable way can be applied to treat Newcastle disease. So, It is most similar to all species of chicken. Briefly, it is consisting bt the migration of the birds to others blank shade, proper vaccine and medicine according to clinical symptoms. Newcastle disease treatment by the given in three ways.
1. Migration of Birds
Firstly, take the decision, if the birds rearing in the floor system, it should be necessary to migration of birds to others shed or in a cages system. The basic aim of the migration of the Newcastle disease are-
– Reducing the contamination from infected feces. which is continually excrete into the litter from an infected bird
– Newcastle disease is a viral disease and has transmitted by the air. Therefore, migration should be needed that prevent NDV contaminated air.
2. By Vaccinations
Primary basic principles to treat infected flock of NDV to induced immunity of Al birds. Nonetheless, It is the best way to upsurging immunity in unaffected birds. furthermore, it is not applicable to diseased birds. The development of immunity depends on species to species
Poultry Comparative Immunity
Laying chicken produces better immunity then broiler chickens due to muscle integrity in the body. Newcastle vaccine stimulates the amino acid profile of the bird’s muscle. More strong protein structure of the muscle of birds, producing more immunity in the body of the birds.
In a comparative study in the field, laying chicken and local domesticated birds having a strong muscular structure compared to broiler birds. Vaccination is required first of the induction of immunity during the outbreak.
Choice of the vaccine strain
Several Newcastle Disease strains are used in the field by poultry experts with their experience.n In early, the consultant suggested lassota live vaccine by eye drop/water to neutralize the disease strain at the primary stage of NDv.
Diseases of poultry, 6 th edition
live lassota produces respiratory distress in a normal live birds and in addition, it is severe during an outbreak.
This is proven now this time. Please avoid lasso after the primary stage of NDV.

The best vaccine during Outbreak
It’s better to used Newcastle disease killed vaccines to produce cell-mediated immunity. Cell-mediated immunity also depends on the Intracerebral pathogenicity index (ICPI) unit of the vaccine strain. Several two killed vaccine strains of Newcastle disease are available which ICP value 0.0.
If the ICP value is higher, it have ability to produce disaese outbreak in the farm.For example Live lassota vaccine has ICP value .40. So, It is must causing disease asymptomic disease in the birds. but, sometimes we can not deserve it. If the condition fevourable condition, it is absulately causin Newcastle disease especially winter season.Diaseases of Poultry, 13 th edition
It means there are no possibilities to produce disease from the vaccine strain.
The strain is ulster & asymptomatic strain have lower Intracerebral pathogenicity index (ICPI) value & produced greater immunity in a short period of time. That’s are fast to reach an immune site. It’s possible to inject the vaccine at first-day infection which is to minimize mortality during the outbreak
3. By Medicine
Newcastle Disease virus (NDv) not single organisms involved in this case but other organisms associated with a disease. The common pathogen is-
Mycoplasmosis, salmonellosis, Pasteurellosis, colibacillosis which caused several lesions such as egg peritonitis, Airsaculitis, Pneumonia, swollen head syndrome, etc.
Choice of drugs
So the application of antibiotics should be needed to prevent these infections & save the birds. It should be avoided to give antibiotics in the oral route to reduce intake water & thus causes dehydration of birds & increased mortality.
Antimycoplasmal drug should be used such as Tiamulin, Tilmycosin, erythromycin, Azithromycin, etc. if refused water & feed intake please avoid oral antibiotics. Enter the injectable solution like ciprofloxacin 20mg/kg, Enrofloxacin 25mg/kg, Tiamulin@ 30mg/kg body weight, tylosin @10mg/kg body weight intramuscular for several days should suggest.
For Gram Positive negative bacterial infection
For better gram-positive bacterial coverage, It is to used Penicillin and cephalosporin up to the second generation at 10mg/kg body weight. Avoid gram-negative bacterial infections using bettered antibiotics which great susceptibilities to gram-negative like Florfenicol, gentamycin, colistin sulfate, neomycin, etc.
for Specific Gram-Negative Bacteria
In poultry, the mostly gram-negative bacteria which causing infection is Enterobacteriaceae origin. The common organism of this family are
salmonella- causing Pullorim disease in chicks and Fowl typhoid in Adult
Escherichia coli- Causing Mushy chick disease, Colibacteriosis, CCRD, Swallen head syndrome, etc
For severe gram-negative bacterial infection, cephalosporin drug of choice in this situation like ceftriaxone @10mg/kg body weight, cefoperazone 12mg/kg, azotonium @10 mg/kg & ceftiofur 7mg/kg body weight should apply for several days.
I have been practicing ceftriaxone at 10mg/kg body weight in a injectable form in the poultry. This is the best drugs on fowl typhoid and fowl cholera when not stopping mortality by the oral route drugs. It have no reference on book or on internet, but i have been starting from human typhoid phenomenum since 2016.Ramzan,DVM, Poultry veterinarian
