Feeding management of meat ducks during the breeding period: 1. Feeding methods: Half-feeding management is generally adopted during the rearing period of meat ducks. Second, transfer group and grouping: 1 week before the group transfer, should be ready for bred duck house, and fill the 29-day-old feeding amount 12 to 24 hours before group transfer, fill the pool water. One set of each group (140 ducks) or two sets of ducks, each group separated by a 0.7-meter-high object to prevent mixing. Mixed polygamy can also be raised separately. Separate males and females can accurately control their weight, but they must mix a small amount of female ducks in the male duck group. The purpose is to make the male ducks have “sexual memories†during the growth process, otherwise it will lead to a decrease in the fertilization rate. Normally every 10 ducks have 1 female duck. Third, the restrictions on feeding: Limiting the purpose of feeding is to control the weight, so that it has a suitable weight for egg production, so that timely sexual maturity and body maturity, reduce the number of eggs produced in the early stage of production and the number of eggs produced in the late stage of production , To prevent excessive weight gain due to overfeeding, to reduce deaths, eliminate the number of; to improve the productivity of ducks (egg production rate and fertility rate); to extend the effective use of breeding ducks, save feed, so as to achieve raising parental generation The economic benefits of breeding ducks. Fourth, light control: The principle is not to extend the lighting time or increase the light intensity to prevent premature sexual maturity. From 5 to 20 weeks of age, natural light is fixed for 9 to 10 hours per day, and natural light is used during actual production. V. Selection of the breeding period: The second choice of breeding ducks is to be performed about 2 weeks before the laying of eggs. The focus of this selection is on breeding male ducks, selecting male ducks that are in line with their weight indicators, have good health status, are lively and sensitive, have good body shape, are plump and plump, have strong feet and are of the best quality. The female ducks are mainly individuals with very weak physiques, and the male and female breeding ratios are 1 to 5 males. 6. Preparation before egg production: If the male and female ducks are reared separately, mix males and females at the age of 18 weeks by the ratio of 1 to 5 for males and females.
