Dr. Asghar Ali Kamboh received his PhD from Nanjing Agricultural University, China, in 2012. He has been working as an associate professor in the Department of Veterinary Microbiology, Faculty of Animal Husbandry and Veterinary Science, Sindh Agriculture University, Tandojam, Pakistan, since 2006. Currently, his research interests are antimicrobial resistance, microbial contamination of animal foods, plant antioxidants, bacterial

pathogens of animal origin, and modulation of immunity and gut microbiota via dietary manipulation in poultry. He has published more than 80 articles in peer-reviewed journals and is an editor/editorial board member of many scholarly journals.

Preface

*Poultry - An Advanced Learning* is a unique compilation as it contains all advanced aspects of poultry production, i.e., from housing design/management to production parameters like production-improving strategies (from the use of traditional herbs to advanced biotechnological tools) and data analysis as well. Thus, this book will be of interest to poultry students, nutritionists, researchers, academicians, farm managers, statisticians, farm engineers/architectures, poultry producers, etc.

In the first chapter, Ayodeji Oloyo (Nigeria) and Adedamola Ojerinde (UK) jointly elaborate the housing designs of various types of poultry farms, particularly those that effectively mitigate the deleterious effects of summer stress. The authors have defined all architectural elements, including building orientation, roof slope, roof overhang, landscape, building height, building width, building length, etc. to design a naturally ventilated building for optimum poultry production. Moreover, the use of a tunnel and inlet ventilation system has also been described to sustain

In the second chapter, Emre Tekce and his colleagues from Bayburt University, Turkey, stress the importance of herbal extracts in poultry nutrition. The authors report the supplemental effects of essential oil mixture of various herbs on the fatty acid profile of broiler meat reared under heat stress. Herbal extracts significantly affect saturated fatty acids, including C14:0, C16:0, and C18:0; monounsaturated fatty acids, including C16:1, C17:1, and C18:1; and polyunsaturated fatty acids, including C18:2n-6c, C18:2n-6t, and C20:1n9 in the breast meat of broiler chickens.

The third chapter is written by Birendra Mishra and his team from the University of Hawaii, USA, on the involvement of hormones, genes/proteins, and their interaction for egg formation in the oviduct of laying hens. There are several genes (e.g., OVAL, TF, OVM, LYZ, COL10A1, etc.), hormones (e.g., FSH, LH, estrogen, etc.), and biological pathways (e.g., calcium signaling pathway, pantothenate and coenzyme biosynthesis, etc.) that trigger histomorphological and biochemical changes in the segments of the oviduct for egg formation. Estrogen regulates folliculogenesis, accumulation of yolk in the follicles, ovulation, and development of oviducts, while progesterone induces the ovulation of yolk from the ovary and

Zhuanjian Li and his colleagues from Henan Agricultural University, China, wrote the fourth chapter of this book on the applications of advanced genomics in poultry production with more emphasis on the use of long noncoding RNAs (lncRNAs). lncRNAs have an important role in the regulation of gene expression at the transcriptional level, thus playing a vital role in many life processes, such as cell differentiation and proliferation, growth and development, organogenesis and tumorigenesis. The regulatory mechanisms of lncRNAs for muscle development, lipid metabolism, and immune modulation in poultry are well documented. Evidence has exhibited that lncRNAs could be a potential application for disease
