Book Description
The main objectives of the current study were to characterize the local chicken (LC) and their production systems in Jordan, to investigate the prevalence of different gastrointestinal helminthes in these systems and to compare the resistance response of LC and Lohmann White (LW) when challenged by different geographic sources of parasites. The study was carried out in the rural areas of northern districts of Jordan. The area is of Mediterranean climate with annual precipitation about 200 - 350 mm. On-farm studies and surveys were carried out in 18 villages with participation of 120 households. The study was accomplished in two phases, the first was conducted from October 2004 to February 2005 and the second was conducted from May to July 2005. On-farm surveys were conducted to investigate biodiversity of LC and their performance potential. A sample of 846 adult LC was phenotypically characterized based on morphology, feather colors, comb shape, and performance. The level of morphological and phenotypic heterogeneity was high. The most predominant chicken type was Baladi chicken (67.3 %) followed by Pakistani (27.7 %) and Brahma (5 %). Naked neck and Frizzled phenotype were occasionally observed in the study area. The Baladi type was characterized by its small size compared to Pakistani and Brahma. It has horizontal body position and large vertical tail. Pakistani type characterized by the upright stance, larger body size than Baladi, the tail slope to be horizontal rather than vertical, soft and long feather, prominent shoulders and narrow stern. Braham has a very large body size, heavy bone and muscles. They are highly feathered birds with heavily feathered legs and toes. Many plumage colors were observed in LC populations. Individual chicken might have single, two or many colors (mottled). The mottled was the most predominant (23.1 %) followed by the black (19.5 %) and light brownish color (19.1 %). Brown and black was relatively prevalent (17.0 %). Other variants like spotted, grey, red, spangled green, and yellow were seen in different proportions. Many comb variants were found, the single comb type was the most predominant (80.3 %). Other variants were Buttercup shape, Double, Pea shape and V-shaped with feather cap.

Book Description
Local chicken farming represents one of the main agricultural activities that provide opportunities for food security and income for many rural families. This thesis describes the production systems and provides a genetic characterisation of local chicken in Oman. It also draws a comprehensive picture of the role that Oman and the Arabian Peninsula played in the transfer and dispersal of chicken by maritime trade between Asia and Africa. The findings of this study should be considered by policy makers for initiating a conservation program of local chicken in Oman.

Book Description
The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. - With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far - Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors - Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research
