Us
Active immunisation of chickens to reduce the respiratory signs of Infectious Bronchitis caud by the variant strain of IB 4-91.
Dosage and administration
At least 3.6 log10 EID50 (1 do) per animal by either spray vaccination, drinking water or intranasal/o
cular administration. Where the number of chickens is between the standard dosages, the next higher dosage should be ud.
Spray method
The vaccine should preferably be dissolved in distilled water or alternatively in cool, clean water. The appropriate number of vials should be opened under water. The volume of water for reconstitution should be sufficient to ensure an even distribution when sprayed onto the chickens. This will vary according to the age of the chickens being vaccinated and the management system, but 250 to 400 ml of water per 1000 dos is suggested. The vaccine suspension should be spread evenly over the correct number of chickens, at a distance of 30–40 cm using a coar spray, preferably when the chickens are sitting together in dim light. The spray apparatus should be free from diments, corrosion and traces of disinfectants (and ideally should be ud for vaccination purpos only).
Drinking water
The vials should be opened under water. U cool, clean water to dissolve the vaccine. For administration of the vaccine, as a general rule, dissolve 1000 dos in one litre per age in days up to a maximum volume of 20 litres per 1000 dos. For heavy breeds, or in hot weather, the quantity
of water may be incread up to 40 litres per 1000 dos. By adding approximately 2 grams of skimmed milk powder or 20 ml liquid skimmed milk per litre of water the virus retains its activity longer. Ensure that all the vaccine suspension is consumed within 1-2 hours. The vaccine should be given in the early morning as this is the main period of water intake or during the cool period on a hot day. Feed should be available when vaccinating. Water should be withheld before vaccination to make the chickens thirsty. The length of time of water deprivation is strongly dependent on climatological circumstances. Water withholding should be kept as short as possible with a minimum of half an hour. A sufficient number of water containers to provide adequate drinking space is esntial. The should be clean and free from traces of detergents and disinfectants. Turn on mains water when all the vaccine water has been consumed.
Intranasal/ocular administration
天津大学研究生院
Dissolve the vaccine in physiological saline solution or sterile distilled water (usually 30 ml per 1000 dos, 75 ml per 2500 dos) and administer by means of a standardized dropper. One drop should be applied onto one nostril or one eye. Ensure that the nasal drop is inhaled before freeing the bird.
Intranasal/ocular administration or coar spray gives the best respon and the should be the methods of choice, especially when vaccinating young chickens.
Vaccination programme
The veterinary surgeon should determine the optimum vaccination schedule according to the local situation.
Guidelines
Broilers
The vaccine can be administered to 1-day-old chicks and older chickens by coar spray or by intranasal/ocular administration. The vaccine can be administered to 7-day and older chickens by drinking water. For prolonged immunity, chickens should be re-vaccinated every 6 weeks after the initial administration.
Future layers and breeders
The vaccine can be administered to future layers and breeders from three weeks of age onwards via intranasal/ocular route, coar spray or drinking water.
Other information
Since the stability of IBV in suspension may be low due to nsitivity to high temperatures and impurities, water ud for the freeze-dried vaccine should be cool and of good quality. By adding skimmed milk to the drinking water the vaccine virus retains its activity longer. Only skimmed milk should be ud, since fat in whole milk may block the automatic drinking systems as well as reduce vaccine virus efficacy.
The vaccine should be ud within 2 hours after reconstitution and should not be stored.
Do not mix or administer with other products.
Only healthy chickens should be vaccinated.
Nobilis IB 4-91 is intended to protect chickens against respiratory signs of dia caud by IBV variant strain 4-91 only and should not be ud as a replacement for other IBV vaccines. Chickens should be vaccinated against other prevalent IBV rotypes (e.g. Massachutts) according to the local IB vaccination programme.
The product should only be ud after it has been established that IBV variant strain 4-91 is epidemiologically relevant in the area. Care should be taken to avoid the introduction of the variant strain into an area where it is not prent.

Contra-indications, warnings, etc
Nobilis IB 4-91 given at day-old can adverly affect the efficacy of Turkey Rhinotracheitis (TRT) vaccine given within 7 days, therefore this vaccination scheme is contra-indicated.
Future layers and breeders should not be vaccinated before 3 weeks of age.
The vaccine virus may spread from vaccinates to non-vaccinated chickens and appropriate care should be taken to parate vaccinates from non-vaccinates. Care should be taken to avoid spread of a vaccine virus from vaccinates to pheasants.
Vaccination with Nobilis IB 4-91 may induce mild respiratory signs, which may persist for a few days, depending on the health and condition of the chickens.
Operator warnings

交换留学生Further information
A good immune respon is reliant on the reaction of an immunogenic agent and a fully competent immune system. Immunogenicity of the vaccine antigen will be reduced by poor storage or inappropriate administration. Immunocompetence of the animal may be compromid by a variety of factors including poor health, nutritional status, genetic factors, concurrent drug therapy and stress. Under certain conditions, for example extreme dia pressure and variant challenge, fully immune chickens may succumb to dia. Therefore, successful vaccination may not be synonymous with full protection in the face of a dia challenge.
