The increase of feed intake at the initial stage of production of laying eggs should follow the principle of gradual and orderly progress. Common mother ducks begin to lay eggs at 21-22 weeks of age. After laying, they should increase their feed by 5-10 grams per week depending on the weight of male and female ducks, in order to prompt ducks to reach 5% of their production as soon as possible. Egg rate. In production, some farmers are eager to start production ahead of schedule, the egg weight of the first egg production and the early egg production peak, etc., and rapidly increase the amount of feed during the early stage of egg production, which will inevitably affect the economic benefits of the entire production period. First of all, too early production, combined with a large initial egg production, is likely to cause the mother's rectal prolapse; Second, the body maturity and sexual maturity of the breeding duck is inconsistent, especially the male duck, although there is sexual desire, but also to crawl, but its semen Poor quality, generally lower hatching rate of fertilized eggs.
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. In the 2-3 weeks before the arrival of the egg production peak, the feeding amount should reach the maximum value, and if the increase of material amount is postponed, the egg production loss will usually be 2-3%. At this time, tentative feeding method was adopted: each duck added another 1-5% of material, and the change of laying rate was observed after 4 days of feeding. If the rate of egg production increased, feed it according to the increased amount of feed, such as the rate of egg production. Change, immediately return to the original amount of feed, 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 feed in the pre-laying period will generally be 10-15% higher than the amount required for the peak period of the production of ducks. The average daily consumption of cherry-meat ducks during the peak period of egg production is 220-250 g/only. 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 10-15% higher feeding amount must be subtracted. Otherwise, the duck will be easily over-fertilized, and the female duck 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 consumes about 10-15 grams of feed. After 2 weeks, the feed of the duck is stabilized at the maximum amount of feed required, and then the feed is fed on a constant basis.
Late egg production
After 48 weeks of age, the meat production rate began to decrease by 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 the age of 48 weeks, it should gradually decrease as the egg production rate decreases. Reduced materials can also adopt tentative reduction methods. Under normal circumstances, the daily feeding amount of ducks in the late stage of production is 80-85% of the peak feeding amount.
