First, see weight feeding The feed quality and feeding amount were determined according to the duck's body weight and egg production rate: (1) The ducklings' egg production rate was still over 80%, and the weight of ducks slightly decreased. At this time, the feed was properly fed. Animal feed (better with fresh snails); (2) Ducks gain weight and the body has a tendency to gain weight. However, when the egg production rate is still 80%, rough feeds and blue-green materials can be appropriately fed, or feed intake can be controlled (each Daily 150g), reduce the amount of feed by 50% for free feeding, do not allow the duck to eat too much fine material, but the animal protein feed should also maintain the original level or increase slightly; (3) normal weight, lay eggs The rate is also higher, and the protein level in the feed can be slightly increased compared to the previous stage; (4) The egg production rate is reduced to 60%, and it is difficult to increase without feeding. Second, see the feces feed If the feces is thick, soft, strip-like, and the surface is lustrous, it can be divided into several segments with the light tapping of the feet, indicating that the fine, coarse, and green materials are properly matched. If the manure is small and solid, the color is black, and the cross-section is grainy after dialing, indicating that the amount of concentrated feed is too much, the amount of green material is small, and the digestion and absorption is not normal, the amount of concentrate feed should be reduced and the green feed should be added. If the excrement is light and not shaped, it will spread out as soon as it is discharged, indicating that the concentrate feed is insufficient and the nutrient is low, and the concentrate feed should be supplemented. If feces are yellowish-white or grayish-green with bad odor, it means the duck is ill and should be treated in isolation. Third, look at the production of eggs If the shape of the eggs is abnormal and small, it means that the lack of nutrients. It is necessary to feed feeds rich in protein, such as bean cakes, peanut cakes, and fishmeal, so that the crude protein content of the diet can be increased to 20%, and the total amount of dietary can be increased appropriately. If the eggshell is thin, translucent, trachoma, rough, or even produce soft shell eggs, indicating that the quality of feed is not good, especially calcium deficiency, or lack of vitamins, bone flour, shell powder, lime powder and other minerals and vitamin D should be added. Rich feeds, such as fish liver oil and inorganic salt additives, can be added when the egg weight is reduced. If the egg production time is concentrated at 2:00 in the morning, it means that the feeding method is effective. If the egg production is delayed every day, and the produced eggs become smaller, the feed must be fed. Fourth, look at the spirit of feeding A healthy duck with a high egg production rate is full of energy, diving time is long, the feathers are smooth and wet after landing, and the water splashes. If the duck is weak and unable to move, it will be afraid to go into the water after it is released. After the water comes into contact with feathers, it may even sink. It means that the nutrition is insufficient. It is necessary to feed animal feed in a timely manner and make up the cod liver oil (to feed the cod liver oil better). Feed in the powder, according to each duck to give 1mL daily, feed 3d stop 7d for a course of treatment, or fed 0.5mL per day, continuous feeding 10d.
