Advanced Poultry: (Breeding And Genetics)

Scientific and technological advancements have led to great expansion of poultry sector in last few decades. The development of genetically superior stocks capable of higher production, even under adverse climatic conditions, has transformed poultry from rural farming to full-fledged industry. With advanced understanding of genetic mediation of animal physiology and behaviour and the discovery of the genome sequences of many species, animal production breeding programs can be improved in both speed and efficiency. Recently, there has been a major shift from the differentiation of poultry breeds according to morphological and feather colouring characteristics, to differentiation based on measurements at the molecular level. With advancement in molecular techniques, the DNA marker technology emerged as a finer tool for assessing the genetic variability. Predicting genomic estimate of breeding value of individual using SNPs across the whole genome paved way to conceptualization of 'genomic selection' which emerged as the most advanced technology to revolutionize the animal production. The book deals with management of poultry production, hormones and metabolism, probiotics in poultry, artificial insemination, mycotoxins, vaccine failure and metabolism in poultry. It presents recent advances in poultry treatment and regulatory mechanism. It utilizes genetic principles to accomplish the goals for meat or egg production. Use of transgenic technology in poultry is also examined in this book. This book will be beneficial for the students, teachers, researchers, farmers and other professionals, who are interested to strengthen and expand their knowledge about chicken products in fields of poultry science, biotechnology, plant science and agriculture.
