Description

An ecological breeding system for geese

technical field

The invention relates to the technical field of ecological animal husbandry, further relates to the ecological breeding technology of poultry, and in particular relates to an ecological breeding system for geese.

Background technique

At present, my country's goose breeding accounts for more than 90% of the world's total, and the number occupies an absolute position, but the degree of industrialization is far from the standard of modern animal husbandry. Traditional farmers generally adopt a single breeding method, that is to breed geese exclusively in independent goose farms. Although this method is relatively common and mature in chicken and duck breeding industry, due to the physiological characteristics and nutritional requirements of interspecific species, etc. There are essential differences in elements, so this model is less efficient in goose breeding and difficult to obtain ideal economic value. Specifically, this kind of breeding mode requires special purchase and configuration of goose feed, and special treatment of manure, so it consumes a lot of time and cost; due to the general lack of waste treatment measures by breeding owners at present, a large amount of goose excrement is likely to be The formation of local accumulation, if not handled properly, will bring a great threat to environmental protection; in addition, because artificial feed often contains chemical additives, it may remain in the body of geese, which brings potential food safety risks, and is also related to green ecology. The development of animal husbandry goes against the direction of development. In this case, if an ecological breeding system combining planting and breeding is developed based on natural conditions, and the nutrient source, living place and waste destination of geese are all incorporated into the natural ecological cycle, it is expected to reduce breeding costs and improve breeding efficiency.

In the prior art, some researchers have tried to develop such a breeding model, but the desired effect has not yet been achieved. For example: Chinese Invention Patent Application (Publication No.: CN106912437A) discloses a method for raising geese in an ecological manor. The method includes the following steps: 1) selecting a breeding site 2) infrastructure construction of a breeding manor 3) supporting facilities and construction in a breeding manor 4) Feeding 5) Ecological treatment of waste water and feces 6) Manor lighting and beautification treatment. Among them, the infrastructure construction of breeding manor mainly includes the construction of goose house. The interior of the goose house is all dug 1-1.5m deep, and the mesh plane is supported by a steel frame for the geese to rest. The feces fall from the mesh area below and are collected periodically with an automatic fecal scraping device. Among them, the facilities and construction in the manor mainly include: hatching area, brooding area, goose breeding area, feed processing and storage area, wastewater treatment, filtration and purification area, ecological protection area, excrement treatment area, personnel accommodation area, and other breeding supporting areas. Among them, the ecological treatment of waste water and excrement mainly includes 1. Wastewater treatment is precipitation, filtration, harmless treatment of aquatic plants, and reuse after filtration. 2. Most of the feces are automatically collected and sold through daily equipment. A small part flows into the water. Some are absorbed by aquatic plants as nutrients, and some are absorbed by fish. Part of it is collected in the sedimentation tank as fertilizer for the flowers and trees in the manor. Among them, the feeding method is mainly captive breeding.

Although this technical solution reflects a certain idea of ecological goose breeding, the manure produced in the breeding cannot be fully utilized in the manor, and needs to be processed through sales, which increases the marketing cost; in addition, the goose feed is mainly obtained through procurement, and the cost is relatively high ; In addition, the breeding method of geese is completely captive. Compared with grazing geese, the quality of geese is difficult to guarantee. Moreover, judging from industry feedback, no related ecological breeding methods including this technology have been applied on a large scale in the goose breeding industry. In this case, it is necessary to develop a more reasonable, Effective ecological breeding system to improve the efficiency and economic added value of goose breeding.

In the above technical solution, the goose house and the grazing grassland are used as the direct breeding places for geese. In the goose house, a net bed is erected at a position 1-1.5m above the ground. The geese rest on the net bed, and their feces fall below the net bed. ; The ground of the goose house has a middle ridge structure, and its two ends are lower and are provided with the water inlet pipe of the sedimentation tank, so that the fecal mixture can flow into the sedimentation tank more smoothly through the water inlet pipe under the condition of artificial washing; The water outlet connected to the sewage ditch, based on this structure, after entering the sedimentation tank, most of the feces and sewage will be deposited in the sedimentation tank, and a small part will enter the sewage purification ditch through the water outlet, which is the waste water in the sewage purification ditch. Animals and plants provide nutrients. The goose manure accumulated in the sedimentation tank needs to be cleaned regularly, which can further be used for earthworm breeding and organic fertilizer production. The impermeable membranes on the ground of the goose house and in the sedimentation tank are used to prevent the penetration of goose manure and water into the ground.

On the grazing grassland, there are sports trails, hybrid wolf tail grassland and sewage purification ditches at intervals. Among them, the sports trail extends in a folded line, and a second net bed connected to the net bed in the goose house is set up above it, which can be used as an activity place for geese when stocking. The goose manure falling on the net bed becomes the natural feed for the grass, and the grass can be eaten directly by the geese; the sprinklers arranged on the sports trail can provide water for the geese and at the same time irrigate the grass.

Hybrid Pennisetum is mound-shaped, so that the grazing grassland is in a high and low undulating state. In addition to hybrid Pennisetum, other grasses such as ryegrass can be planted. The sewage purification ditch located between the two adjacent hybrid wolf tail grasslands is also called the forage productive sewage purification ditch. Aquatic plants are planted in it. At the same time, aquatic animals such as snails and fish can be raised at the bottom of the ditch to increase economic added value. ; Since the sewage purification ditch is connected with the sedimentation tank, the sedimented sewage can flow into the sewage purification ditch, which not only provides nutrients for the animals and plants in the sewage purification ditch, but also purifies the sewage. The outlet end of the ditch flows into the artificial wetland, which can become the water resource of the artificial wetland. Since the anti-seepage film on the side wall of the sewage purification ditch only reaches about half of its height, it can play an overflow role. When the water level of the sewage purification ditch is too high, the sewage can overflow from both sides, thus irrigating the hybrid wolf tail grassland. effect.

The artificial wetlands located next to the grazing grasslands should be lower than the grassy grasslands. Plants such as canna, water jasmine, cigu, long eardrum, Shuitongcai, cress, and watercress can be grown, which can be used for viewing and feeding. ; The sewage from the sewage purification ditch is further purified in the constructed wetland while providing water source for the wetland, so as to meet the discharge standard.
