How to prevent duck infectious serositis? Detailed explanation of treatment options

Livestock Farming 0 views
[Preventive measures] (1) Strengthen feeding management: avoid excessive stocking density and overcrowding of ducks; the duck flock should follow all-in/all-out management, with disinfection and emptying of the house for 2 to 4 weeks; litter should be kept as dry as possible. (2) Immunoprevention: vaccines for this disease have been used to prevent it, with good results. Formalin-inactivated vaccines made from strains of different serotypes, with ducklings immunized once each at 2 and 3 weeks of age, can maintain protection from disease until 7 weeks of age, but the above method requires the vaccine to be used twice, which is not easy to promote and apply in the field. A combined inactivated vaccine of Escherichia coli and Riemerella anatipestifer has also been trial-produced, and test results show that it can significantly reduce mortality more than the use of Riemerella anatipestifer inactivated vaccine alone. In recent years, the United States has successfully developed an attenuated live vaccine including serotypes 1, 2, and 5; this vaccine, administered to 1-day-old ducklings by aerosol or drinking water immunization, can produce significant protective effects. In China, China Agricultural University, South China Agricultural University, Sichuan Agricultural University, and the Guangdong Provincial Institute of Poultry Science, among other institutions, have in recent years conducted a large amount of effective research on the prevention and control of this disease, and the inactivated vaccines developed have been promoted and applied over a relatively large area, with good immunization results. Cheng Anchun and others at the Poultry Disease Prevention and Control Research Center of Sichuan Agricultural University, targeting the short rearing cycle of commercial ducks, developed the "duck infectious serositis propolis composite adjuvant inactivated vaccine" and the "duck infectious serositis-duckling Escherichia coli multivalent propolis composite adjuvant combined inactivated vaccine"; the latter was mainly developed to address the characteristics of concurrent infection of this disease with duck Escherichia coli. After trial use, it overcame the shortcoming of oil-emulsion vaccines in producing immunity slowly, and resistance to challenge with virulent strains could be achieved on the 5th day.

[Treatment options] The following medication methods are now introduced for reference in field prevention and treatment: (1) Gentamicin, intramuscular injection at 4000 to 8000 units per kg body weight, 1 to 2 times daily, for 2 to 3 consecutive days. (2) Lincomycin-spectinomycin, mixed into feed at 0.0044% of the active drug ingredient, for 3 to 5 consecutive days. (3) Compound diaveridine, mixed into feed at 0.04%, with 4 to 6 days as one treatment course. (4) Penicillin and streptomycin: 5000 to 10000 units each for ducklings, and 40000 to 80000 units each for growing ducks, by intramuscular injection.
