Feeding methods for different laying periods of ducks of different breeds

Duck

First, the initial stage of egg laying. Female ducks generally begin to lay eggs at the age of 21-22 weeks. After laying eggs, they should add 5-10 grams of feed per duck per week according to the weight of male and female ducks, so as to promote the laying rate of ducks to reach 5% as soon as possible. However, in production, some farmers unilaterally pursue early laying, egg weight, egg production peak ahead of time, etc., in the initial stage of egg production, rapidly increase the amount of feed, which is bound to affect the efficiency of the whole laying period. First of all, the beginning of laying too early, coupled with the initial egg production is too large, it is easy to cause female duck anus prolapse; secondly, breeding duck body maturity and sexual maturity are not consistent, especially male ducks, semen quality is poor, fertilized egg hatching rate is low.

Second, the early stage of laying eggs. During the rising period of egg production, feed should be increased rapidly to induce ducks to reach the egg laying peak as soon as possible. The amount of feed should reach the maximum in 2-3 weeks before the peak of egg production. If you postpone the increase of feed, you will lose 2-3% of your eggs. At this time, it is necessary to check whether the laying rate of female ducks has reached its peak. Methods: the exploratory feeding method was adopted to add 5-10 grams of feed to each duck. After 4 days of continuous feeding, the change of laying rate was observed. If the laying rate increased, it would continue to be fed according to the increased feed amount. If there was no change, it would immediately return to the original feed quantity. This method can be used many times.

Third, the peak period of egg production. In production practice, in order to make the peak period of egg production come, the maximum amount of feed in the early stage of egg production is generally 10-15% higher than that of this breed of duck during the peak period of egg production. The amount of feed is generally not reduced during the peak period of egg production, and the highest level is maintained all the time. However, after the peak of egg production, the excess feed must be reduced by 10-15%, otherwise ducks will be overfat, especially male ducks, which will have difficulty or unwillingness to climb hips, and female ducks will also produce fewer eggs because of overweight. The weight reduction after the peak period should be combined with egg laying week age, egg laying rate and egg weight. 2 weeks after the egg production rate no longer rises, the diet begins to begin, usually at the age of 21-32 weeks. At this time, the egg weight should be more than 90 grams. The average feed consumption of each duck was reduced by about 10-15 grams. After 2 weeks, the feeding amount of breeder ducks was stabilized at the maximum amount of feed needed, and quantitative feeding was adopted.

Fourth, the later stage of egg laying. After 48 weeks of age, the laying rate of meat ducks began to decline at a rate of 1-2% per week. Because the female ducks had fully matured at this time, and the egg weight remained stable accordingly, the nutritional requirements of female ducks began to decrease. If the feeding amount was not reduced at this time, fat deposition would inevitably result in fat deposition, which would lead to the decline of egg laying rate in the later stage, resulting in feed waste. Therefore, the feed should be reduced gradually with the decrease of laying rate from the age of 48 weeks. Diet reduction can also be used tentatively, that is, the average daily feed consumption of each duck is reduced by 5 grams for 4 days. If the egg laying rate decreases greatly during this period, the original feed quantity should be restored immediately; if the decrease is normal, it should be fed according to the feed quantity after reduction. This method is repeated every 10 days. In general, the daily feeding amount of breeder ducks in the late laying period is 80-85% of that in the peak period.
