It is widely recognised that developments in the chick embryo have a profound effect on hatchability and the subsequent health and productive capacity of poultry. With a stronger focus on welfare, prevention of disease and more sustainable poultry production, understanding these early stages has never been more crucial. Embryo development and hatchery practice in poultry production addresses the key stages and factors in embryo development in poultry to optimise hatchability and chick health. The book reviews the role of parental and environmental factors on embryo development and skeletal growth. The book also reviews the effects of incubation on chick health and development, including factors such as temperature, light exposure and humidity, as well as best practice in managing the hatching stage. Through focussed and authoritative discussions, the book details best practices for managing a hatchery environment to ensure that chick welfare, health and productive capacity are optimized.
