Key Technical Points for the Feeding and Management of Geese at the Middle Goose Stage
Geese from 1 month of age to sexual maturity are called middle geese or growing geese. Middle geese have a large feed intake and strong digestive capacity; this is precisely the period of rapid growth of their bones, muscles, and large feathers. 1) Grazing: Before grazing, middle geese should undergo wing clipping, cutting off the metacarpal and phalangeal bones on one side or severing the extensor digitorum muscle and the extensor carpi radialis longus muscle; those whose wounds heal after 1 week can then be released onto water and grazed. The grazing area must have a sufficient quantity of green fodder and grain feed; grazing time should be chosen in the morning and evening, and at noon the geese should be driven to rest in the shade of trees beside a pond, and they should be released onto water after each full feeding. Where water-release conditions are poor, grass can be cut for feeding and the geese released onto water separately.
