Features: To help breeders quickly master the technology of raising economic animals, we have organized relevant technical personnel to write the "Technology of Raising Economic Animals" series. During the writing process, we strive for depth with simplicity, making it easy to understand. Readers can refer to the methods introduced in the series to perform practical operations. This series focuses on the breeding value, life habits, breeding and raising techniques, daily management, and disease prevention of economic animals. Some contents and operational methods of the rare birds introduced in this book are similar and can be used for reference. Considering that some breeders may raise one or two varieties, we have provided appropriate introductions in each section. Additionally, some diagrams in this volume can also be used for reference.
