Feed ducks and ducks to see the feeding method
First, look at the weight feed to determine the feed quality and feeding amount according to the duck's weight and laying rate: (1) The ducklings' egg production rate is still above 80%, and the duck body weight is slightly reduced. In the feed properly fed animal feed (better fresh snails); (2) ducks gain weight, the body has a tendency to gain weight, but the egg production rate is still 80%, can be appropriately fed roughage and blue-green material, or control Feed intake (150g per day), reduce the feed intake by 50%, and prevent the ducks from eating too much concentrate, but the animal protein feed should maintain its original level or increase slightly; (3 ) Normal body weight, high egg production rate, and slightly higher levels of protein in feed than in previous stages; (4) Egg production rate has dropped to 60%, and it is difficult to rise without feeding. Second, to see the feces feed if the feces is thick, loose, strips, shiny surface, can be divided into several sections with the foot light dial, indicating that the fine, thick, green material with a reasonable. 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 egg production if the egg shape is abnormal and small, indicating that lack of nutrition, must be fed with bean cake, peanut cake, fish meal and other protein-rich feed, so that the crude protein content of diets increased to 20%, and an appropriate increase in the date Total food. 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, to see the spirit of the feeding rate of high egg production rate of healthy ducks, energetic, long diving time, feathers smooth and wet after landing, the body of water splashed. 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.
