What's the difference between planting eggs and eating them?

There must be several healthy and relatively strong cocks among the laying hens. The source of breeding eggs should first pay attention to the quality of breeding chickens, and choose the breeding eggs of chickens with stable genetic performance, excellent production performance, high fertility and good health.

Ordinary edible eggs can't have the participation of roosters, and there are only hens in the flock.

2. Will chicks hatch?

Breeding eggs are fertilized eggs, and edible eggs are unfertilized eggs. Only the former can hatch birds, and they can't be distinguished from each other in appearance.

Breeding eggs can be used to hatch various eggs for breeding young birds.

3. Different internal characteristics

If the egg is irradiated on the light bulb, a small circle of shadow appears on one side of the egg (that is, the side with air holes when eating boiled eggs with shells), which means that the egg is fertilized and is an egg, while the egg without shadow belongs to edible eggs.

Quality requirements for breeding eggs

1, to ensure the freshness of eggs, the shorter the storage time of eggs, the better, the best storage period is 7 days, with 3 ~ 5 days left. The hatching rate of eggs can be kept within two weeks. If it exceeds two weeks, the hatching period will be delayed, the hatching rate will be reduced, and there will be more weak ducklings. The freshness of eggs is not only related to the storage time, but also to the storage temperature, humidity and method.

2, shape and size, egg shape should be normal, oval, too long and too round, two-pointed and other county species should not be used for planting eggs, eggs should meet the requirements of varieties, should not be enlarged too small, ducklings with too small egg weight are smaller, and eggs with too large egg weight have low hatching rate. The egg weight of large meat ducks is generally 85 ~ 95g.

3. The eggshell has compact and uniform structure, normal surface and moderate thickness. The thickness of eggshell is generally 0.035 ~ 0.04 mm, which is too thick and hard, and it is heated slowly when hatching, and the water is not suitable for evaporation, and the gas exchange is poor, so it is not easy to break the shell. When it is too thin, the water evaporates too quickly and the hatching rate decreases. Eggshell is not suitable for breeding eggs because of its uneven structure and rough surface.

4. The cleanliness of the eggshell surface, there should be no dirt such as feces and soil on the eggshell surface, otherwise pathogenic microorganisms in the dirt will invade the breeding eggs, leading to the deterioration of the breeding eggs. Or because dirt blocks the pores, which hinders the gas exchange of eggs and affects the hatching rate. At the same time, the machine was polluted during incubation. If a few kinds of eggs are slightly polluted, they should be treated before hatching.
