Laminating and horizontally-spreading type hatching method for swan geese

Abstract

The invention discloses a laminating and horizontally-spreading type hatching method for swan geese, and relates to the technical field of cultivation. Firstly, square pipes of 4 cm * 6 cm are welded or punched through screws, so that a framework with the height of 1.8 m, the width of 2 m and the length of 4 m is formed; secondly, square pipes of 4 cm * 6 cm are used for encircling the framework from top to bottom at intervals of 50 cm, the framework is welded into four layers, then each layer of the frame is tiled with a wooden plate, each wooden plate is tiled with a rush straw mat, small square pipes are welded all around in positions which are 20 cm higher than edges of two layers below the framework, so that guardrails are formed; manual heating is adopted, so that the indoor temperature is raised to 28-32 DEG C, hatching eggs fertilized for 18-20 days are transferred onto a horizontally-spreading frame from an incubator, two layers of hatching eggs are placed along the peripheries of two layers above the horizontally-spreading frame, a layer of eggs is placed in the middle, and then the hatching eggs are covered with floss silk quilts or common quilts; cold boiled water spraying and egg airing are performed, particularly, the water is sprayed six times every day, and the hatching eggs are transferred to the lower two layers of the horizontally-spreading frame after the water is prayed continuously for 5-6 days; and the eggs are observed for 1-2 days, water spraying and egg airing is stopped when shells are pecked, the room temperature is maintained to be in a range from 35 DEG C to 38 DEG C, and the swan geese are waited to be hatched naturally. The method effectively improves the hatchability and saves energy, and compared with the original hatchability, the hatchability is improved to about 90%.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a stacked flat gray swan hatching method. Background technique [0002] Gray swan, also known as wild goose, wild goose or swan, is a swan goose in the genus Anastylus. It has a large body and a feather weight of 7-8 kg. The meat is delicious, with high amino acid and mineral content. It is an ideal health food. , Yiyang Qi, blood circulation and other medicinal value, favored by consumers. The gray swan's staple food is green forage grass, supplemented with grains appropriately, and does not eat meat, additives and other smelly items. It is a pure green food. Restricted by its unique genetic genes, the meat is delicious, tender, full of game, rich in nutrition, and fat-free, second only to pure swan. It is the only health food goose with dual medicinal liver and meat in the world. It has been favored at home and abroad since it was listed, the market is very promising, and t...
