Problems solved by technology

[0003] In order to solve the problem of difficult mating of small and medium-sized meat ducks in cages, the present invention provides a method for improving the reproductive performance of small and medium-sized meat ducks in cages. Screening, finally select the male duck with strong breeding ability and screen out the breeding method with the highest fertilization rate and male-to-female ratio

Embodiment 1

[0022] Take the Wuzui high-quality meat duck currently being cultivated as an example

[0023] (1) Selection of ducklings: After hatching, the male and female ducks are first identified by pinching the anus. The male and female ducks are selected to retain the appearance characteristics. Healthy and strong ducklings wear foot numbers. Males and females are separated and raised in large groups.

[0024] (2) Cultivation of male and female ducks in the breeding period: After reaching the age of 4 weeks, the male and female ducks are raised in single cages, and the cages of the male and female ducks should be as close as possible during the cage raising stage (for example, the cages of male and female ducks are set alternately), so that the male and female ducks Memories of the mother duck.

[0025] (3) Selection of male ducks in the breeding period: male ducks are raised to 4 weeks old and 9 weeks old, selected according to appearance characteristics and body weight, and elimin...

Embodiment 2

[0039] When the technology of the present invention is not applied, the male and female ducklings are mixed and reared in large groups, and the male and female ducklings are reared in single cages during the growing period, with random cage positions and random rotation patterns.

[0040] Breeding by the best technical scheme in Example 1 for two years, it was found that the fertilization rate of small and medium-sized meat duck breeding eggs increased by 28.78% than when the technical scheme was not adopted. Table 4 shows the fertilization rate of small and medium meat duck eggs during two years of breeding.

Abstract

The invention discloses a method for improving the reproductive performance of caged small-medium-sized meat breeding ducks. After the hatching and during a rearing period, unqualified breeding ducksare eliminated in time, the appearance characteristics of male ducks that meet the breed requirements and are moderate in weight and healthy and strong are selected, and then through the screening ofbreeding by one-to-one, male and female ducks different rotation methods and different ratios, the male ducks with strong breeding ability, a breeding method with high fertilization rate and a suitable male-female ratio are selected. The problem of difficult breeding of the caged small-medium-sized meat breeding ducks is effectively solved. The unqualified reserve breeding ducks are eliminated intime after hatching and in the rearing period, only the best quality male ducks are reserved for breeding, unnecessary breeding of redundant male ducks is avoided, the breeding cost is reduced, the method is simple and easy to operate, and the reproductive efficiency of the caged meat breeding ducks is high.

Description

technical field [0001] The invention belongs to the field of poultry breeding, and in particular relates to a method for improving the reproductive performance of small and medium-sized meat ducks in cages. Background technique [0002] The traditional duck breeding mode mainly adopts a low-input, open production mode. This breeding mode produces a large amount of sewage and waste, pollutes the environment, and duck diseases are prone to cross-infection, and drugs are frequently used, so the safety of meat duck products cannot be guaranteed. The advantages of the cage mode are: 1. It can increase the stocking density and save space; 2. The ducks move less, which can save feed and improve the feed conversion rate; 3. Ducks get less disease. However, a prominent problem in breeding duck cages is that male and female ducks are difficult to breed. Usually, artificial insemination technology must be used, but this technology requires high operability. Once the key points cannot b...
