Embodiment Construction

[0020] The present invention is a kind of method for the conservation and breeding of ducks, which comprises the following process steps:

[0021] 1) Selection of breeding ducklings: Each patrilineal half-sib family in the previous generation kept eggs for 20 days. According to the birth weight, each paternal half-sib family initially selected 15 male ducks, and all female ducks were reserved for breeding; among them, the breeding males Selection indicators: eggs are mostly born with a weight of 35-45 grams; eggs with a large family are born with a weight of 40-50 grams;

[0022] 2) Appearance evaluation and body size measurement: When the male ducks reach 120 days, the appearance and body size evaluations are carried out, and 5 male ducks are selected and reserved for breeding;

[0023] 3) Determination of production performance: Determination of birth weight, 60-day-old weight, and start-of-production weight every day; and the number of eggs laid, total egg weight, and feed ...

Abstract

The invention relates to a preserving and breeding method for ducks. The preserving and breeding method includes the process steps of 1), duckling selection; 2), appearance evaluation and body measurement; 3), production performance measurement; 4), family assessment; 5), duckling preservation; 6), raising management. In the preserving and breeding method, a natural selection method is adopted on selection of original ducklings, sick individuals are removed, hatching eggs are randomly selected and preserved each autumn, and after hatching, the ducklings are selected and preserved according to the ratio of male and female. The preserving and breeding method for the ducks has the advantages of being simple in method, good in scientificity, applicable to industrialized preservation and the like.
