Description:<\/p>\n
\u201cAvivac-IBD\u201d is prepared from virus-containing material of diverse origin (cell cultures, extraembyonic liquid, carcases and choryoallantois membranes of SPF chicken embryos) infected with a mild strain of Gamboro disease virus (\u201cWinterfield 2512\u2033).<\/p>\n
The vaccine is a dry homogenous porous brownish pink substance that easily dissolves in water without formation of flakes or precipitate.<\/p>\n
The titre of the vaccine virus should be not less than 4,0 lg EID50\/cm3.<\/p>\n
The vaccine has no side effects; it is safe and non-reactogenic at the dose recommended.<\/p>\n
The vaccine possesses no therapeutic properties.<\/p>\n
Indication for use:<\/p>\n
The vaccine is used for prophylactic immunization of birds in farm units threatened or affected by Gamboro disease. Only clinically healthy birds should be subject to vaccination.<\/p>\n
The vaccine is administered in drinking water to 7 to 15-day-old chickens twice at an interval of 10 to 14 days. Time of vaccination depends on the epizootic situation of IBD.<\/p>\n
One day before administration, the volume of water consumed by one bird for 1 to 1,5 hours should be measured. The vaccine is then diluted so that this volume contains one dose of the vaccine.<\/p>\n
The vaccine is dissolved\/diluted in clean boiled water cooled to room temperature. To stabilize the virus, non-fat dry milk can be added to the diluted vaccine at a rate of 5% by weight. Water or equipment treated with disinfectant must not be used for vaccination. Birds should be kept without water for 2 to 3 hours. Feed and water may be given to the birds at least 2 hours after administration.<\/p>\n
Meat from vaccinated chickens can be used for food without restriction.<\/p>\n
