Breed conservation method for Sansui ducks

Abstract

The invention discloses a breed conservation method for Sansui ducks. The breed conservation method for the Sansui ducks is characterized by including the first step of establishing Sansui duck original species groups, collecting hatching eggs from more than five villages and towns in a Sansui duck main aquiculture area, carrying out disinfection and hatching on the hatching eggs after egg selection, duckling selection and mature duck selection, preserving the Sansui ducks with obvious varietal characteristics, wherein families are set up among the 120-day-old Sansui ducks according to the proportion of one male duck to ten female ducks, and each family includes twenty female ducks and two male ducks to form a zero-generation species group, the second step of carrying out family-tree hatching, that is, labeling family numbers, male duck poultry rings and female duck poultry rings, arranging egg laying boxes, collecting the hatching eggs at a set time, carrying out hatching with the individual families as the unit and labeling the family numbers and female duck numbers on ducklings, and the third step of reserving breeding ducks in a random equivalent mode, wherein according to the requirements of 'reserving the ducklings equivalently in all the families and carrying out random apolegamy', every two years is regarded as one generation, the breeding ducks are selected and reserved according to the proportion of twelve female ducks to one male duck when the ducklings grow to 120 days, and new families are merged totally and randomly reestablished according to species groups of the selected and reserved breeding ducks.

Description

technical field [0001] The invention relates to the field of genetic resource protection of poultry, in particular to a method for preserving original species of waterfowl. Background technique [0002] Animal genetic resources are the result of long-term evolution of life on earth, and are the material basis for the generation and sustainable development of human beings. my country is one of the countries with the most abundant genetic resources of livestock and poultry in the world. These livestock and poultry resources are an important material basis for cultivating new breeds and strains, protecting biodiversity, and realizing the sustainable development of animal husbandry, and are also important for meeting future breeding needs. gene bank. However, in the past 30 years, due to historical and practical reasons, many precious animal genetic resources in our country have been greatly damaged. A considerable number of livestock and poultry breeds are in a state of scarcit...
