Collection and selection of duck eggs
1、 Collection of duck eggs
Breeding ducks are generally raised by house feeding or grazing, and corresponding measures should be taken for the collection of breeding eggs according to different feeding methods.
Under the grazing and feeding conditions, because there is no egg box, the eggs are laid on the bedding or the ground, so it is very important to collect the eggs in time. The laying time of laying ducks is concentrated between 1:00 and 6:00 in the evening. With the extension of laying age, the old laying time is postponed: most of the females in the late laying period also lay eggs before 10:00 in the morning. The timely collection of eggs after production can reduce the damage of the eggs and the degree of contamination of the eggs. This is an important measure to maintain the quality of the eggs and improve the qualification rate and hatchability of the eggs. The breeding ducks raised by grazing can be driven out for grazing after the eggs are laid.
The breeding ducks raised in the house can be provided with an egg box in the house; Keep the bedding in the house dry at any time, especially the bedding in the egg box should be fresh, dry and soft; The mother who has just given birth has been trained to lay eggs in the egg-layer; At the same time, the number of egg picking should be increased, which is the most important link in the breeding process of breeding ducks during the laying period.
When the temperature is below 0 ℃, if the seed eggs are not collected in time, the seed eggs will receive the road for a long time; When the temperature is hot, the eggs are susceptible to heat. Too high or too low ambient temperature will affect the normal growth and development of the embryo.
