Comparison of various immune responsiveness traits in divergent stocks of chicken: A review

The poultry industry during the past two decades has been one of the most dynamic and ever expanding sectors in the world. Worldwide poultry production is being undertaken under a wide variety of climate, production and management conditions and the losses occurring due to diseases are large. Development of stocks resistant to wide variety of diseases i.e. general disease resistance, offers a good prospect of reducing the expenditure on prophylactic and vaccination programmes. The comparative evaluation of immunological responses of genetically diverse chicken stock of layer and broiler chicken will help in the development of stocks with higher production potential and with increased resistance to pathogen, parasites and non-specific stresses. The information presented in this review paper shows that it would be worth comparing these traits in divergent stocks of chicken
