Description

Ventilation device for poultry breeding greenhouse

technical field

The invention relates to the field of agricultural technology, in particular to a ventilation device for poultry breeding greenhouses.

Background technique

Poultry refers to artificially raised birds, mainly for their meat, eggs and feathers, but also for other purposes. Generally, they are pheasants and ducks, such as chickens, ducks, geese, etc. There are also birds of other families such as turkeys, pigeons, quails and various songbirds. In addition to providing human meat and eggs, poultry also provide their feathers and feces. It also has important economic value. Chicken is rich in protein, and its fat contains unsaturated fatty acids, so it is a better protein food for the elderly and patients with cardiovascular diseases.

The cold resistance of chickens is poor. The body temperature of the newly hatched chicks is 3°C lower than that of adult chickens, and it takes 10 days to reach normal body temperature. In addition, the chicks have short and thin fluff and cannot keep out the cold, so they are not adaptable to the environment. Only by artificial heat preservation can the chicks grow and develop normally. Breeding greenhouses can improve the survival rate of chicks. At present, most of the ventilation work for breeding greenhouses is to directly open the greenhouse door or lift the film to ventilate directly.
