Breeding method for increasing fertilization rate of egg-laying breeding ducks

Abstract

The invention discloses a breeding method for increasing a fertilization rate of egg-laying breeding ducks. The breeding method is different from the prior art in that male breeding ducks and female breeding ducks are raised separately and managed correspondingly according to different physiological features, a management process is simplified, and sexual maturity of the male breeding ducks and female breeding ducks can be realized beneficially at corresponding stages; the male breeding ducks are subjected to gradual light increase regulation before mating to facilitate gonad development, and possibility of maldevelopment, malformation or poor semen quality is greatly decreased; before mating, the female breeding ducks are fed with female duck feed having additives and take exercises appropriately to keep balance of in-vivo proteins and amino acids during egg laying, so that egg laying uniformity and long egg laying peak duration are realized; after being raised in a same region, the ducks are forced to have activities in water to increase the fertilization rate, and only one male breeding duck is left in each mating region to avoid mutual influences of the male breeding ducks.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a breeding method for improving the fertilization rate of laying ducks. Background technique [0002] With the development of the economy and the improvement of the people's level, the breeding of ducks is becoming more and more large-scale. In the breeding process, the number of eggs laid by laying ducks and the quality of laying ducks are directly related to the interests of farmers. For breeding eggs Duck also requires a higher fertilization rate and egg production rate. The existing breeding technology usually improves the fertilization rate by selecting excellent breeding ducks and providing them with a good breeding and breeding environment. However, after reaching a certain fertilization rate , no further improvement. Contents of the invention [0003] The object of the invention is to provide a breeding method for improving the fertilization r...
