Feeding and Management of Duck during laying period

1. Feeding and management in the early and early stages of egg laying.

In the early laying stage (150-200 days old) and early laying period (2018-300 days old), the key point is to increase the dietary nutrient concentration and feeding times to meet the nutritional needs and ensure that the ducks reach the laying peak smoothly. When the laying rate reaches 50%, each duck adds 10 grams of fishmeal per day; when the laying rate is 70%, 15 grams of fishmeal is added; 18 grams of 20 grams of fishmeal is added when the laying rate is more than 90%, and this level will be maintained later. The feeding times increased from 3 times a day to 4 times a day, 3 times in the day and 1 time at 10: 00 at night. The average light intensity is 14 hours, and it should increase gradually from short to long. During this period, the bigger the duck eggs, the faster the yield increase, indicating that the better the feeding and management. Otherwise, find out the cause in time and improve it. The laying rate increased gradually, especially in ducks that began to lay in early spring. Generally, at the age of 200 days, the laying rate can reach about 98%. If the egg laying rate goes up and down or even decreases, it is the reason of feeding. The duck is sampled and weighed once a month (when the duck is fasting in the morning). If the average body weight is close to the standard weight, it shows that the feeding management is proper; if it exceeds the standard weight, the proportion of coarse feed should be reduced or increased; if it is lower than the standard weight, it means that the feed quality should be improved.

2. Feeding and management in the middle stage of egg production.

In the middle stage of laying (301-400 days old), the key point is to ensure the high yield of ducks, and strive to maintain the peak laying period beyond 400 days old, the dietary nutrient concentration should be slightly higher than before, each duck should be fed with 22 grams of fishmeal per day, or fed with a diet containing 20% protein, 150 grams per duck per day, and more green feed and calcium. Feed 150 grams of aquatic plants per day, or add multivitamins and 1-2% granular shell powder. The light is stable at 16 hours a day. The temperature should be maintained at 5: 10 ℃. If it exceeds or falls below this standard, it should be adjusted. Daily operating procedures remain stable. At this time, if the eggshell is smooth, thick and shiny, it means the quality is good. If the egg shape becomes longer, the shell is thin and bright, there are sand spots, or even soft-shell eggs, indicating that the feed quality is poor, especially the lack of calcium, or lack of vitamin B, should be supplemented. If the laying period is about 2 o'clock at night, the laying time is concentrated and the eggs are laid neatly, it shows that the feeding and management is proper. Otherwise, measures should be taken in time.

3. Feeding and management in the later stage of egg production.

The key point is to determine the feed quality and feed quantity according to the body weight and laying rate of laying ducks in the later stage of laying (401-500 days old). If the laying rate of ducks is still more than 80%, and the weight of ducks decreases slightly, animal feed should be added to the feed properly; if the body weight increases, the metabolic energy in the feed should be properly reduced or the feed intake should be controlled; if the body weight is normal, the crude protein in the feed should be slightly higher than that in the previous stage. Keep the light at 16 hours a day, drive ducks around the house three times a day for about 5-10 minutes each time, and supplement cod liver oil and minerals when eggshell quality and egg weight drop. Keep the microclimate and operation procedure in the duck house relatively stable and avoid stress reaction.
