Embodiment 1

[0079] Embodiment 1, raising cage house

[0080] 1. Main design

[0081] In this embodiment, a breeding cage suitable for growth is manufactured for artificially raised mandarin ducks.

[0082] The inventor has found through long-term observation that an important reason why mandarin ducks are difficult to reproduce is that they are easily stimulated, which leads to the generation of stress response. In order to reduce the stress response of mandarin ducks to promote their reproduction, the inventors set the cages in a quiet environment, which means that the maximum limit of environmental noise is 40 decibels ("The People's Republic of China Urban Area Noise Standards" Clearly stipulates the maximum limit of environmental noise in five types of urban areas: sanatorium areas, high-end villa areas, and high-end hotel areas, 50dB during the day and 40dB at night; areas dominated by residences and cultural and educational institutions, 55dB during the day and 45dB at night; , co...

Embodiment 2

[0091] Embodiment 2, the design of nest box

[0092] The cage house 100 also includes a plurality of nest boxes 300, which are made of seven plywood materials. Provide resting places for mandarin ducks.

[0093] The nest box is arranged in the cage house, and it has top plate 310, bottom plate 330 and side plate 320; The sides are wider in size and face most of the cage, while the back faces the main face.

[0094] The distance between the bottom of the nest box and the bottom 110 of the cage is 2.2 meters. The transverse width of the nest box is about 40 cm.

[0095] The nest box connects to the side 130 of the cage and extends circumferentially along the side such that the back of the nest box, which is not accessed by mandarin ducks, abuts the side of the cage. Wherein, the length extending along the circumferential direction is determined by the width of the nest box, the distance between adjacent nest boxes, and the number of nest boxes, and the distance between adjac...

Embodiment 3

[0102] Embodiment 3, mandarin duck food production

[0103] Two kinds of mandarin duck food are set, that is, regular food and breeding food. Based on the daily food consumption of a single mandarin duck, the food formula includes:

[0104] Conventional food formula: 60g of green vegetables, 10g of apples, 40g of pellet feed, 40g of corn bread, and 10g of corn.

[0105] Breeding food formula: 60g green vegetables, 10g apples, 40g pellet feed, 40g corn bread, 10g corn, 5g cooked ground beef, 10g cooked soybeans, 10g boiled eggs, and 20g malt.

[0106] Usually when feeding, refer to the above formula, and the fluctuation is within 10%.

[0107] In the previous study, the inventor adopted a single method of feeding, that is, no matter in the breeding period or the non-breeding period, all adopted the above-mentioned "conventional food formula" for feeding, the hatching rate was 20-35%, and the individual reproduction rate was 5%. And follow-up, the present inventor utilizes " ...

Abstract

The invention provides a method and device for promoting the reproduction of mandarin ducks. Aiming at the technical defect in the field that the difficulty for artificial reproduction of the mandarinducks is very high, the inventor carries out deep researches on a plurality of factors including living habits, groupment, foods and benefits of the mandarin ducks to disclose the method and device for promoting the reproduction of the mandarin ducks. The reproduction of the mandarin ducks is remarkably promoted through optimizing an artificial feeding environment, and the sustainability of population development is maintained.

Description

technical field [0001] The invention belongs to the field of zoology, and more specifically, the invention relates to a method and a device for promoting the reproduction of mandarin ducks. Background technique [0002] Mandarin duck (Aix galericulata) common name: official duck, English name: mandarin duck, is a small duck in the family Anatidae of Anseriformes, mainly distributed in eastern Asia, breeds in northeast China, and overwinters in south China. The habitat environment of mandarin ducks is mountain streams, swamps, lakes, etc., and it is also common in swamps surrounded by broad-leaved forests and water surfaces overgrown with reeds. Nests are nested in natural tree holes close to the old trees near the water. They start to lay eggs in early May, and each nest lays 7-12 eggs. Due to the destruction of the wild environment, deforestation and hunting, the population of mandarin ducks in the wild has decreased year by year, and it is listed as a national second-clas...
