Genetics of Disease Resistance in Chicken
Although poultry industry has gained momentum during the last few decades, there are still various impediments like improper infrastructure, unscientific management and above all various deadly infectious diseases which incur huge economic losses on poultry industry. These diseases include viral diseases like Avian Influenza, Marek’s Disease, New Castle disease and bacterial diseases like Colibacillosis, Pasteurellosis and Salmonellosis, etc. Development of disease resistant poultry has been found successful practice over the use of drugs or vaccines for disease control. Studies involving genome wide associations to figure out certain candidate genes that are involved in disease resistance have also been carried out. Single nucleotide polymorphism studies to unveil the mechanisms underlying disease resistance in chicken show that SNPs and other candidate gene approaches play a vital role in providing disease resistance. Also, understanding the genes and biological pathways that confer genetic resistance to various infections will lead towards the development of more resistant commercial poultry flocks or improved vaccines against various diseases. This chapter shall focus on various factors involved in disease resistance in chicken that interact with the pathogen and provide resistance against the pathogen.
