摘要

广泛的家禽生产系统(通常称为“自由放养”)是基于允许鸟类进入家禽舍外觅食区域的做法。在20世纪中叶左右，在开发出更高产的家禽品种和更好的管理设施(自动饲养和浇水、更好的住房、环境控制)之前，这种系统被广泛采用。

LESSON 4

The extensive system of poultry production (commonly known as “free-range”) is based on the practice of allowing the bird access to foraging areas outside the poultry house. This system was widely practiced prior to the development of more productive strains of poultry and better management facilities (automated feeding and watering, better housing, environmental control) around the middle of the 20 century.
