96 96 VACCINATION The success of vaccination is determined essentially by the following factors: � selection of suitable vaccines � selection of appropriate vaccination times � selection of suitable vaccination methods � condition of birds to be vaccinated Salmonella Fowl Adenovirus infections Avian Influenza Vaccinations are preventive measures against infectious diseases and help to keep flocks healthy and productive. The idea is to build up a protective shield during the early stages of life to protect our birds for upcoming challenges they might face in their future life in production. Different regional epidemic situations and legal regulations require customised vaccination programs. One general vaccination programme suitable for all individual needs does not exist. Therefore, in the following we want to give general information and guidelines about how to create a vaccination program. Your local veterinarian should be consulted as they will be aware of issues within your region and availability of different vaccines. LOHMANN › MANAGEMENT GUIDE › HEALTH COCCIDIOSIS Coccidiosis is the most important endoparasite in poultry. If not controlled it could cause high economic losses due to enteritis and arguably mortality. Sub-clinical infections harm feed conversion and uniformity. To ensure immunity against coccidiosis, two methods are commonly used: VACCINATION Vaccination is probably the best way to control coccidiosis in floor-reared breeders. Usually, chicks are vaccinated via spray already in the hatchery. Other options are applying the vaccine in the rearing farm or via spray on the feed or via drinking water. A proper management of the vaccine during the first three to four weeks in the rearing farm is crucial to develop a strong immunity. Special focus should be on litter quality and humidity. 65% of air humidity or a minimum of 25% humidity in the litter are recommended to enable the 3–4 cycles of reinfection of the vaccine. ANTICOCCIDIAL DRUGS Where permitted by law, birds may be treated with anti- coccidial drugs during the first 10 weeks of life.
