Early egg production
The increase of feed intake in the early stage of laying should follow the principle of gradual and orderly progress. Common mother ducks start egg production between 21 and 22 weeks of age. After laying, the ducks should be fed at a rate of 5 to 10 grams per week, depending on the weight of the male and female ducks, to promote ducks to reach 5 as soon as possible. % of egg production rate. First of all, the premature start of production, coupled with the initial production of eggs is too large, likely to cause the mother duck to recoil anus; Second, the body maturity and sexual maturity of ducks inconsistent, especially the male duck, although there is sexual desire, but also to crawl, but its semen quality Poor, general fertilized eggs hatching rate is low.
Pre-laying
During the early egg-laying period, the amount of feed should increase rapidly to induce the duck group to reach the peak of the egg production as early as possible. The maximum amount of feed should be made between 2 weeks and 3 weeks before the peak of egg production. If the increase of feed amount is delayed, the loss of egg production will be 2% to 3%. At this time, tentative feeding method was used: the feeding amount of each duck was increased by 1% to 5%. After 4 days of feeding, the change in laying rate was observed. If the laying rate was increased, feed it according to the increased amount of feed. The egg rate did not change and immediately returned to the original feeding amount. This method can be used multiple times.
Egg production peak
In order to ensure that the peak period of egg production is on schedule, the maximum amount of eggs in the pre-laying period is generally 10% to 15% higher than the amount of eggs needed for the peak period of the ducks. The average daily consumption of cherry-meat ducks at the peak of egg production was 220 grams to 250 grams. Do not reduce the amount of feed during the peak period of the whole production, and always maintain the highest level. However, after the arrival of the peak of production, the feed must be reduced by 10% to 15%. Otherwise, it is easy to cause over-fertilization of the ducks, and the female ducks will also be reduced due to over-fertilization. After the peak period of reduction, we must combine the age of the laying eggs, the egg production rate, and the weight of the eggs. After the egg production rate no longer rises, we need to start reducing the material within 2 weeks. Each duck consumed 10 g to 15 g of feed. After 2 weeks, the feed of the duck was stabilized at the maximum amount of feed required, and constant feed was used.
Late egg production
After 48 weeks of age, the meat production rate began to decline at a rate of 1% to 2% per week. At this time, female ducks have fully reached body maturity, and the egg weight remains stable. The demand for nutrients in female ducks begins to decrease. If we do not reduce the amount of feed at this time, it will inevitably cause the deposition of fat, which will cause the fatness of the female duck body, resulting in a sharp decline in the rate of egg production at the later stage, resulting in a waste of feed. Therefore, from 48 weeks of age, it should be gradually reduced as the egg production rate declines. Reduced materials can also adopt a tentative reduction method. Under normal circumstances, the daily feeding amount of ducks in the late stage of production is 80% to 85% of the peak feeding amount.
