Feeding also needs to be carried out according to the disease. Feeding the laying duck needs four views.

Egg duck

First, look at the weight feed. The feed quality and feeding quantity are determined according to the body weight and laying rate of laying ducks: 1. The laying rate of ducks is more than 80%, while the body weight of laying ducks tends to be reduced slightly. At this time, animal feed is added appropriately (fresh snails are better). 2. Ducks gain weight and tend to get fat, but when the laying rate is 80%, you can appropriately increase roughage and green feed, or control feed intake (150 grams per day), reduce free intake by 50%, and do not allow laying ducks to eat too much concentrate. However, animal protein feed should maintain the original level or slightly increase; 3. If the body weight is normal and the laying rate is high, the level of protein in the feed can be slightly increased compared with the previous stage. 4. The egg laying rate has dropped to 60%, which is difficult to rise, and there is no need to add ingredients.

Second, look at the fecal feed. If the feces are thick, soft, strip-shaped, the surface is shiny, and gently dialed with your feet, it can be divided into several sections, indicating that the collocation of fine, coarse and green materials is reasonable. If the feces are small and strong, the color is black, and the cross-section is granulated after dialing, it shows that the amount of 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 not shaped, it will spread out as soon as it is discharged, indicating that the concentrate is insufficient and the nutrition is on the low side, so it should be fed with fine feed. If the feces are yellow-white or gray-green and have a foul smell, it means that the duck is sick and should be treated in isolation.

Third, look at the egg-laying feed, if the egg shape is abnormal and small, indicating insufficient nutrition, it is necessary to add high-protein feed such as bean cake, peanut cake and fish meal, so that the crude protein content of the diet can be raised to 20%, and the total amount of the diet should be increased appropriately. If the eggshell becomes thin, transparent, trachoma, rough, or even produce soft shell eggs, it shows that the feed is of poor quality, especially calcium deficiency, or vitamin deficiency, minerals such as bone powder, shell powder, lime powder and feed rich in vitamin D should be added. if the weight of eggs is reduced, cod liver oil and inorganic salt additives can be added. If the laying time is concentrated at 2: 00 in the morning, it shows that the feeding method is good. If the egg production is postponed every day and the egg body becomes smaller, it is necessary to increase the feed.

Fourth, look at the spiritual feed. The healthy laying duck with high laying rate is energetic and has a long diving time. after landing, the feathers are smooth and the water is splashed everywhere. If the egg duck is in low spirits, weak in action, and afraid of going into the water, after launching, the feathers are sticky and wet, or even sink, indicating insufficient nutrition, the duck should be fed fresh animal feed in time, and make up cod liver oil (to feed cod liver oil is better), mix it in the powder, give each duck 1 ml a day, feed for 3 days, stop for 7 days, for a course of treatment, or feed each duck 0.5 ml daily for 10 days.
