Breeding management of Wulong goose;
There are many farmers in Shandong rural areas for the scientific breeding technology of Huoyan Goose, and the scale of Huoyan Goose breeding is closely related to economic benefits. There are a large number of geese, a large number of slaughter, high labor efficiency and great results. The size of the feeding scale should be determined according to the conditions of farmers' labor funds, forage resources and market sales.
If the conditions are not perfect enough and the feeding technology can't keep up, there is no need to pursue large-scale, otherwise the feeding management is not good, the production performance of geese will decline, and the disease and death will increase, but the loss will outweigh the gain. Generally, about 500 meat geese are raised in agricultural products, and about 50 geese are bred/kloc-0; Large professional households can raise more geese appropriately, and the number of meat geese can be1000 ~ 2000; The number of geese can be 500 ~1000.
In the breeding of gouge-eyed geese, forage grass is generally planted to raise them. The selection of forage crops should be combined with long-term and short-term. We should combine leafy vegetables and grasses rich in protein tender and juicy, but give priority to leafy vegetables.
