Method for breeding artificially-cultured wild spot-billed ducks out of season and net cage device used in method

Abstract

The invention discloses a method for breeding artificially-cultured wild spot-billed ducks out of season and a net cage device which is used in the method, and belongs to the technical field of a poultry farming industry. A greenhouse, the wide spot-billed ducks and feed are used in the method. The method comprises the following steps of: stimulating wing tips of each wide spot-billed duck by acupuncturing; straightening and fixing hocks of each wide spot-billed duck by using curly barks; from the day when the wide spot-billed ducks lay eggs, feeding the wide spot-billed ducks on the feed in which 3-8 g of vitamin C is added per 50 kg; creating a seasonless and nightless spring-like homothermal environment in the greenhouse; feeding the wide spot-billed ducks on special out-of-season breeding feed into which crude protein is added, wherein the special out-of-season breeding feed comprises the following materials in percentage by weight: 60 to 70 percent of corns, 18 to 22 percent of wheat middling, 8 to 12 percent of soybean meal, 4 to 6 percent of rapeseed meal, 0.25 to 0.36 percent of table salt and 1.5 to 2.0 percent of bone meal; and placing the wide spot-billed ducks into a plate-drawing-type net cage which is special for breeding the wide spot-billed ducks, placing the plate-drawing-type net cage in the homothermal environment of the greenhouse and breeding the wide spot-billed ducks on nets. The method has the advantages that two breeding periods of the wide spot-billed ducks in Autumn and Winter are increased every year, the using amount of the feed is reduced, the production cost is greatly reduced, and economic benefit is increased.

Description

technical field [0001] The invention relates to an off-season breeding method of artificially cultured wild ducks and a net cage device used therefor, in particular to an off-season breeding method of artificially cultured spot-billed wild ducks and a net cage device used therein, and belongs to the technical field of poultry farming. Background technique [0002] Spot-billed mallard is one of the ancestors of domestic ducks. It is a special waterfowl with strong adaptability, wide feeding habits, resistance to rough feeding, less disease and easy breeding. Spot-billed wild duck meat is tender, delicious, high in protein, low in fat, low in cholesterol, rich in essential amino acids, fatty acids and mineral elements, and is a high-quality health-care meat food. The development of spot-billed mallard duck production is a breeding industry with high economic value. However, due to the sharp decline in the number of over-hunted people over the years, it has been listed as a na...

Problems solved by technology

[0004] The purpose of the present invention is to aim at the above-mentioned prior art, because spot-billed mallard " brooding " problem, every year can only breed in spring, has caused the defect of sales off-season, provides a kind of artificial culture spot-billed mallard off-season breeding method and The net cage device used can avoid the problem of "brooding" of spot-billed mallards, and can breed in spring, autumn and winter every year, and can be sold all year round.
