1. Look at the weight: The ducklings have an egg production rate of over 80%, but the weight of the ducks slightly decreases. The animal feed should be fed appropriately. The weight of the ducks increases and the body has a tendency to gain weight, but the egg production rate is still At 80%, the roughage and green feed may be appropriately fed, or by controlling the feed intake, so that the ducks will not eat too much fine material, but the animal protein feed should also maintain its original level or increase slightly; normal weight, The egg production rate is also higher, and the protein level in the feed is slightly higher than in the previous stage; the egg production rate is reduced to 60%, and when it is difficult to pick up, there is no need for feeding.
2. To see the feces: If the duck's feces is thick, soft, strip, the surface is shiny, can be divided into several sections after the foot with a light dial, indicating that the fine, thick, green material with a reasonable; feces small and solid, black color, dial The rear section is granular, indicating that the amount of concentrated feed is too little, the amount of green material is small, digestion and absorption are not normal, the amount of concentrate feed should be reduced, and the green feed should be increased; the excrement is light in color and unshaped, and the excrement is dispersed, indicating that the concentrate feed Insufficient feeding, low nutritional levels, supplements should be fed fine material; feces was yellow-white or gray-green, foul smell, indicating that the duck is sick, should be isolated treatment.
3. Look at the production of eggs: If the egg shape is abnormal and small, it means that there is insufficient nutrition. You must feed feeds rich in protein such as bean cakes, peanut cakes, and fishmeal, increase the content of crude protein in the diet to 20%, and increase the number of foods appropriately. Total grain; shell thinning, translucent, with trachoma, rough or soft shell, indicating poor feed quality, especially calcium deficiency or vitamin D deficiency, should add bone meal, shell powder, lime powder and other minerals and vitamin D Rich in feed; If the weight of eggs is reduced, add cod liver oil and inorganic salt additives; If the egg production time is concentrated at 2 am, indicating that the feed is appropriate, such as the daily delay in egg production, and the eggs become smaller, you must feed.
4. Look at the spirit: Healthy ducks with high egg production rate are energetic and have long diving time. When they go ashore, the feathers are smooth and wet, and when the hairs are shaken, they are splashed with water. If the duck is weak and unable to exercise, it will be afraid of the water after it is released, feathers will be wet after the water is poured, or even sink, indicating that the diet is undernourished. It is necessary to feed animal feed in a timely manner and make up the cod liver oil. Clean fish liver oil is preferred. Feed in the powder, feed each duck 1 ml per day, feed for 3 days and stop for 7 days as a course of treatment, can also feed 0.5 ml per day, continuous feeding for 10 days.
