1 look at the weight
The laying rate of ducks is more than 80%, and the weight of ducks is slightly reduced. Animal feed should be properly fed. The body weight of ducks increases, and the body also has a tendency to gain weight. However, when the egg production rate is still 80%, appropriate Feeding roughage and green feed, or controlling the feed intake, does not allow ducks to eat too much concentrate, but animal protein feed should also maintain its original level or increase slightly.
2 look at feces
If the duck's stool is thick, soft, strip-like, and the surface is shiny, it can be divided into several sections after being lightly dialed, indicating that the fine, coarse and green materials are well matched; the stool is fine and firm, the color is black, and the cross section is granular. It indicates that the amount of concentrate is too much, the amount of green material is small, the digestion and absorption are not normal, the amount of concentrate should be reduced, and the amount of concentrate should be increased; the color of the feces is light, not formed, and it is scattered when discharged, indicating that the concentrate is not fed enough, nutrition The level is low, and the concentrate should be replenished; the stool is yellowish white or grayish green, and there is a foul smell, indicating that the duck is sick and should be treated in isolation.
3 see the production of eggs
If the egg shape is abnormal and small, it means that the nutrition is insufficient. It is necessary to feed the protein-rich feed such as bean cake, peanut cake and fish meal, increase the crude protein content in the diet to 20%, and increase the total amount of the diet; eggshell Thin, bright, with blisters, rough or soft shell, indicating poor feed quality, especially calcium deficiency or vitamin D deficiency, should add bone minerals, shell powder, lime powder and other minerals and vitamin D rich feed; Egg weight reduction, can increase cod liver oil and inorganic salt additives; egg production before 5 o'clock in the morning, indicating that the feed is appropriate; if the egg production time is delayed, and the egg is getting smaller and smaller, there may be a shutdown, and the concentrate should be quickly replenished.
4 look at the spirit
When feeding ducks, if the ducks come quickly, it means that the appetite is very strong, you can feed more properly; if you don't get together when feeding, you should feed less. The healthy duck with high egg production rate is full of energy and long diving time. After landing, the feathers are smooth and not wet, and the water droplets splash when shaking. If the duck is not energetic, the action is weak, and after being released, it is afraid of getting into the water. After the water is wet, the feathers are wet and even sinking, indicating that the diet is insufficiently nutritious, and the animal fresh live feed should be added in time to make up the cod liver oil.
