serum for viral; diseases
what about serum preparation in advance commercially for viral diseases treatment during the disease at poultry farm?

Commercial serum therapy isn’t practical in poultry due to short antibody life and large dosage needs. Prevention through vaccination and strong immunity remains the best strategy.

Good

Thank you

Commercially prepared sera are not typically used to treat viral diseases in poultry. Instead, prevention through vaccination and strict biosecurity is the standard approach. Once viral infection occurs, supportive care and management practices are applied, as there are no specific antiviral treatments for most poultry viruses.

Commercially prepared serum in advance for poultry is not a standard practice for treating viral diseases during an outbreak. The more common and effective approach is using hyperimmune serum produced by vaccinating a separate group of animals (like chickens) and collecting their blood to harvest the antibodies. These antibodies can then be used for treatment, or vaccines are used preventatively. A direct-acting antiviral treatment is generally not available as a commercially prepared serum.

Excellent, thanks

Commercially prepared serum for poultry is not a common, widespread product for treating viral diseases, unlike vaccines. Instead, hyperimmune serum is typically prepared on a large scale in specialized labs for specific diseases, like Newcastle disease, and distributed to farms when an outbreak occurs. The process involves inoculating animals, such as rabbits or chickens, with a specific virus or its components, followed by a period of time to allow them to develop a high level of antibodies. The blood is then collected from these animals to produce the hyperimmune serum. This serum is then purified and made available to veterinarians for use in treating infected flocks.

Passive immunization or serum therapy is generally not considered as safe or feasible in poultry as-
1. Provides short duration of protection
2. Risk of transmitting other pathogens
3. Difficulties in collecting & standardising adequate serum quantities from birds
