The ducklings have an egg production rate of more than 80%, but the weight of ducks slightly decreases. Animal feed should be fed at appropriate times. Ducks gain weight and the body has a tendency to gain weight, but the egg production rate is still 80%. Feeding roughage and green feeds appropriately, or by controlling their feed intake, will not allow the ducks to eat too much concentrate, but animal protein feeds should also maintain their original levels or increase slightly; normal weight, and egg production rate Higher, 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 recover, there is no need for feeding.
Second see the feces
If the duck's excrement is thick, soft and sticky, the surface is lustrous, and can be divided into several segments after lightly dialing with the feet, indicating that the fine, coarse, and green materials are reasonably matched; the excrement is small and solid, the color is black, and the cross section is granular after dialing. It shows that the amount of concentrated feed is too much, 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, not forming, and it will spread out as soon as it is discharged, indicating that the concentrate feed is insufficient and nutritious. If the level is low, the concentrate should be supplemented; the feces is yellowish-white or gray-green with bad odor, indicating that the duck is ill and should be treated with isolation.
Three looking eggs
If the shape of the egg 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 fishmeal to increase the content of crude protein in the diet to 20%, and to appropriately increase the total amount of the diet; eggshell 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 feed; Reduced egg weight can increase cod liver oil and inorganic salt additives; if egg production time is concentrated at 2 AM, it means that the feeding is appropriate. If the egg production is delayed every day, and the egg becomes smaller, the feed must be fed.
Four to see the spirit
A healthy duck with a high egg production rate is energetic and has a long diving time. When it goes ashore, the feathers are smooth and wet, and when the hair flutters, water droplets splash. 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.
