Egg duck feeding is fastidious.

First, look at the weight feed

Determine the feed quality and feed quantity according to the body weight and laying rate of laying ducks:

The laying rate of ① ducks is still more than 80%, and the weight of ducks tends to lose slightly. At this time, animal feed should be added to the feed (fresh snails are better).

② ducks gain weight and tend to gain weight, but when the laying rate is still 80%, they can appropriately increase roughage and green feed, or control feed intake (150g per day).

③ has normal body weight and high laying rate, and the protein level in the feed can be slightly higher than that in the previous stage.

④ egg production rate has dropped to 60%, has been difficult to rise, no need to add ingredients.

Look at the fecal feed

If the feces are thick, soft, strip-shaped, and the surface is shiny, the feet can be divided into several sections, indicating that the fine, coarse and green materials are reasonable. If the feces are small and strong, the color is black, and the cross-section is granulated after dialing, it shows that the concentrate feed is too much, the amount of green feed is less, and the digestion and absorption is abnormal. If the dung color is light and does not take shape, it will spread out as soon as it is discharged, indicating that the concentrate feed is insufficient and the nutrition is on the low side. If the feces are yellowish white or grayish green and have a foul smell, it means that the duck is sick and should be treated in isolation.

Look at the feed for laying eggs

If the egg shape is abnormal and small, indicating insufficient nutrition, it is necessary to add feed rich in protein, such as bean cake, peanut cake and fish meal, so as to increase the crude protein content of the diet to 20%, and appropriately increase the total amount of the diet. If the shell becomes thin, transparent, trachoma, rough or even produce soft shell eggs, it shows that the feed quality is not good, especially calcium deficiency, or vitamin D deficiency, bone powder, shell powder, lime powder and other minerals and vitamin D-rich feed should be added. For example, cod liver oil and inorganic salt additives can be added when egg weight is reduced. If the laying time is concentrated at 2: 00 in the morning, it means that the egg is fed properly, such as postponing egg production every day, and the egg body becomes smaller, it is necessary to increase the feed.

Fourth, look at the spiritual feed

Healthy ducks with high laying rate are energetic and dive for a long time, with smooth feathers and splashing water after landing. If the duck is in low spirits, unable to move, afraid of going into the water after release, and the feathers are wet or even sinking after launching, indicating insufficient nutrition, the ducks should be fed fresh animal feed and cod liver oil in time.
