Main Challenges in Poultry Farming. Hatchery Vaccination

Description

The number of new technology vaccines available has been increased worldwide, as well as their widespread use in the poultry industry, especially at hatchery level. Therefore, an updated review withpractical and visual approachs has been developed in order to highlight the importance of hatchery vaccination in poultry farming, whatever the vaccination technique used (in ovo, subcutaneous or spray vaccination), to control the main diseases affecting this species (infectious bursal disease, Newcastle disease, infectious laryngotracheitis, etc.). This handbook has been written by an expert with a wideexperience in this field. Numerous graphic resources have been included to complement the information provided and make the contents more understandable and accessible to readers.

Mohamed Faizal Abdul-Careem

Dr. Mohamed Faizal Abdul-Careem is Assistant Professor (virology) at the University of Calgary (Canada) since 2010. He has obtained his basic veterinary degree (BVSc) from the University of Peradeniya(Sri Lanka) and a Master of Veterinary Medicine degree (MVM) from the University of Glasgow Veterinary School (UK) in 1995. He completed his PhD degree from the University of Guelph (Canada) in 2008. His doctoral thesis entitled “Characterization of Host Responses Following Marek’s Disease Virus Infection or Vaccination Against Marek’s Disease”. Following his PhD degree, he was awarded a prestigious Canadian Institutes of Health Research Fellowship to conduct post-doctoral research on innate immune responses generated against mucosal viral infections at the Center for Gene Therapeutics of the McMaster University (Canada). He is diplomate of American College of Poultry Veterinarians (ACPV) and American College of Veterinary Microbiologists (ACVM).

He has expertise and strong interests in the area of avian viral immunology. He has around 31 manuscripts published in peer-reviewed journals and 90 % of these manuscripts are on avian viral immunology. His research programme at the University of Calgary is supported by grants from Canadian federal, provincial and poultry industry sources such as Natural Sciences and EngineeringResearch Council of Canada, Alberta Livestock and Meat Agency (ALMA), and Canadian Poultry Research Council. He has established state-of-the-art research facility for his experimental animal and laboratory work at the University of Calgary.
