The initial and early stage of egg production (150 days to 200 days) and the previous period (201 days to 300 days) need to increase the nutrient concentration and feeding times in the diet to meet the nutritional needs and ensure that the ducks reach the peak of egg production smoothly . When the egg production rate reaches 50%, 10 grams of fish meal is added to each duck every day; 15 grams of fish meal is added when the egg production rate is 70%; 18 grams to 20 grams of fish meal is added when the egg production rate is more than 90%. The number of feedings increased from 3 to 4 times a day, 3 times during the day and 1 at night. The average light 14 hours, and should gradually increase from short to long. The larger the duck eggs during this period, the faster the increase in production, indicating that the better the feeding and management. The egg production rate of ducks produced in early spring rises faster, generally to 200 days, and the egg production rate can reach about 98%. If the egg production rate goes up or down or even declines, it is due to feeding. Samples are weighed on a monthly basis (on a fasting morning duck) once, and if the average body weight is close to the standard body weight, it means that the husbandry and management are appropriate; if the standard body weight exceeds the standard body weight, it indicates that there is excess nutrients, and the proportion of the coarse material should be reduced or increased; if it is lower than the standard body weight, It shows that lack of nutrition should improve feed quality. In the middle period (301 days to 400 days), the focus of this period is to ensure high duck productivity. After the peak period is maintained at 400 days, the dietary nutrient concentration should be slightly higher than that of the previous period. Each duck will add 22 grams of fishmeal daily. Or feed 20% protein in batches, eat 150 grams each day, but also appropriate to feed more green feed and calcium. Each herb feeds 150 grams per day, or multivitamins are added, and 1% to 2% of granular shell powder is added. The light is stable for 16 hours every day, and the temperature is maintained at 5°C~10°C. If it exceeds or falls below this standard, it should be adjusted. Routine operating procedures remain stable. At this time, if the shell is smooth and thick, shiny, indicating good quality; if the egg shape becomes longer, the shell is thin and translucent, there are sand spots, and even soft shell eggs, indicating poor feed quality, especially insufficient calcium, or lack of vitamin B , Should be added; If the egg production period is about 2 o'clock in the middle of the night, egg production time is concentrated, and the production of eggs is neat, indicating proper feeding and management, otherwise, measures should be taken in time. In the later period (401 days to 500 days), the feed quality and feeding amount were determined according to the duck body weight and the egg production rate. If the ducklings' egg production rate is still above 80% and the duck’s body weight is slightly reduced, animal feed should be properly added in the feed; if the weight is increased, the metabolic energy in the feed should be appropriately reduced or the feed intake should be controlled; If the body weight is normal, the crude protein in the feed should be slightly increased compared to the previous stage; the light is kept at 16 hours per day, and the ducks are circulated in the house 3 times a day, about 5 minutes to 10 minutes each time, and the eggshell mass and egg weight When dropped, add cod liver oil and minerals. Keep the microclimate and operational procedures in the duck house relatively stable and avoid stress reactions.
