About the product

is a live dry vaccine against infectious bursal disease based on virus

The vaccine is prepared from extraembryonic fluid, homogenized carcasses and chorioallantoic membranes of SPF chicken embryos infected with infectious bursal disease virus strain BG. The vaccine has the appearance of a homogenous dry pinkish brown porous substance that easily dissolves in water without forming flakes or sediment. The vaccine is available in hermetically sealed vials containing of the product.

Biological properties

One immunizing dose of the vaccine contains 3,0 lg EID50/cm 3 infectious bursal disease virus. Immunity in vaccinated chickens forms over a period of after vaccination and lasts throughout the entire period during which the birds are susceptible.
The vaccine is innocuous and non-reactogenic; it possesses no therapeutic properties.

Indications for use

Only clinically healthy birds of are subject to vaccination. Chickens aged 7–21 days are vaccinated via drinking water. Time of vaccination is chosen on the basis of maternal antibody levels in the birds’

The day before vaccination the volume of water consumed by one bird in the group subject to immunization over a period of 1,5 hours is evaluated.

Before vaccination the number of doses equal to the number of chickens in the group is diluted in water at a rate of one dose per volume consumed by one chicken. vaccine is then placed into a drinking bowl that underwent treatment with disinfectants.

The robustness of post-vaccination immunity to IBD is evaluated vaccination by way of performing serological testing (virus neutralization assay, gel diffusion precipitation test, ELISA) using diagnostic kits licensed for use in Russian Federation.

Vaccination is considered successful if not less than 80% of the immunized chickens demonstrate mean antibody titres against infectious bursal disease virus exceeding the minimum threshold value specified by the manufacturer of the kit by 100%

If antibody titres fall below this level, re-vaccination must be conducted.

Storage requirements
The shelf life of the vaccine is 12 months from the date of manufacture if stored and transported in a dark dry place at a temperature between +2 and +10°С.

Virus vaccine against infectious bursal disease based on BG strain

Description

The vaccine is intended for infectious bursal disease prevention in chickens by establishment of strong and specific immunity. Dosage form is a freezedried substance for suspension production. Visually the vaccine is a dry homogenous porous substance of brown color. The substance is easily soluble in water within 1–2 min.

Indications

The virus vaccine is intended for IBD prevention in the IBD infected farms and on farms at IBD risk using different types of poultry breeding. Only clinically healthy 7–21-day old birds are vaccinated. Exact date of the first vaccination depends on the epidemic situation on the farm and maternal antibody level.

Route of administration

The vaccine is administered with drinking water twice at 10–14-day interval. A day before vaccination amount of water consumed by one bird during 1.5 hours should be calculated and total amount of water consumed by all vaccinated birds should be determined. For vaccination the necessary amount of the virus vaccine doses correspondent to the number of vaccinated chickens should be dissolved in the determined amount of water and distributed in waterers prewashed without disinfectants.

Chilled, boiled chlorine- and ferrum-free water (at not above 20°C) supplemented with 1% of dry skimmed milk is used for drinking water vaccination.

Egg-laying chickens are deprived of water for 4–8 hours; broilers – for 2–3 hours. Water may be given in 2 hours after immunization.

The vaccination is considered successful when in 14 days post double vaccination the ELISA titer in 90% of chicken sera is twice as high as minimal positive value prescribed in the manufacturer’s instruction to the test-kit.

Immunity

The vaccine induces active immunity against infectious bursal disease agent in 14–21 days post double administration. The immunity should last for the whole production life of the birds. One immune dose of the vaccine contains 103 EID50 of the IBD virus (BG strain). The vaccine is innocuous and has no therapeutic properties.

Storage conditions

Manufacturer, customer and distributor should store the vaccine in original boxes (and in shipping container) in dry and dark place at 2–8°C. The vaccine shelf-life is 12 months from the date of production.
