Ducks feeding in different egg production periods

First, the initial stage of laying eggs. The increase of feed intake in the early stage of laying should follow the principle of gradual and orderly progress. General female ducks begin to lay eggs at 22 weeks of age. After laying eggs, they should be fed at a rate of 5 to 10 grams per week depending on the body weight of the male and female ducks, in order to prompt the ducks to reach 5% of their production as soon as possible. Egg rate. Attention should not be given to the one-sided pursuit of early production and rapid increase in the amount of feed to avoid premature breeding of ducks, plus the initial production of eggs is too large, resulting in the mother duck recoil. Second, pre-laying. In the pre-laying period (increasing egg production period), the amount of feed should increase rapidly. Induce the duck group to reach the peak of egg production as soon as possible. Feeding capacity should be maximized 2 to 3 weeks before the peak of egg production. If the increase of feeding amount is delayed, egg production will often be reduced by 2% to 3%. At this point, tentative feeding method can be adopted, and each duck is increased by 5% to 10% feed. After 4 days of feeding, observe the change in egg production rate. If the egg production rate increases, feed it according to the increased amount of feed; There is no change in the rate and the amount of raw material is immediately restored. This method can be used multiple times. Third, the peak period of egg production. In order to ensure that the peak egg production period is on schedule, the maximum amount of feed in the early stage of breeding ducks is 10% to 15% higher than that required for peak production of ducks in this breed (average each Daily consumption of 220 to 250 grams), but after the arrival of the peak of the production of eggs must be reduced by 10% to 15% higher, otherwise it will result in fattening ducks, especially the duck will climb difficult or do not want to climb The female ducks will also suffer from reduced egg production due to excessive fat. Fourth, the late peak of egg production. In the later stage of egg production, the age of the laying eggs, the egg production rate, and the weight of the eggs should be combined. After the egg production rate no longer rises, the material is cut in 2 weeks, generally starting from 31 weeks of age, and the reduction rate can be larger. Each duck consumes 10 to 15 grams less per day. After 2 weeks, normal feeding is again performed. Fifth, late egg production. After laying ducks 48 weeks of age, the egg production rate began to decline at a rate of 1% to 2% per week. Since the female ducks had fully reached body maturity and the egg weight remained relatively stable, the demand for nutrients from ducks began to decrease. If the amount of feed is not reduced at this time, fat deposits will inevitably be caused and the mother ducks will be over-fatted, resulting in a sharp drop in the rate of egg production at the later stage and causing a waste of feed. Therefore, from the age of 48 weeks, it should gradually decrease as the egg production rate decreases.
