Duck brooding methods include ground breeding, online brooding and three-dimensional cage brooding.
1 Ground brooding is to lay 5cm thick soft litter on the ground of the brooding house, feed the ducklings directly on the bedding, and use underground (or aboveground) heating pipes, coal stoves, nanny umbrellas or red line bulbs. Such heating methods increase the temperature in the brooding house. This method is simple and easy to use, and the investment is low. However, the utilization rate of the house is low, and the ducklings are directly in contact with the faeces. The feathers are dirty and susceptible to diseases.
2 On-line brooding refers to the installation of metal nets, plastic nets or bamboo-grid bars 30-80 cm above the ground in the brooding house. The young ducklings are kept on the Internet and faeces fall from the crevices of the meshes or bars onto the ground. In this way, ducklings do not come into contact with the ground, and the chances of infection are reduced. The utilization of premises is more than doubled than that of ground rearing, which increases labor productivity and saves a lot of litter. The disadvantage is that the one-off investment is larger.
3 Stereo cage is the practice of feeding ducklings in special multi-layer metal cages or bamboo cages. This kind of brooding can use buildings and heat more efficiently than plane brooding. It has the advantages of online brooding and can also increase labor. Productivity, disadvantages are also large investments. The current production of commercial ducks uses online brooding or three-dimensional cages, and meat-based ducks generally use ground brooding or online brooding.
