In this example: in the step of establishing a high-yield laying hen basic group, a hen group of a high-yield Roman grey laying hen variety needs to be selected, the number of the group is more than 10 ten thousand, in the step of establishing the high-yield laying hen basic group, the hen needs to be 2100 grams in weight at 300 days old, 310 in yield at 72 weeks old, 65 grams in average egg weight and 91 percent in egg fertility rate, in the step of selecting double-fallopian tube individuals, in the artificial insemination process, the oviduct condition of the individual needs to be observed, in the step of selecting the high-fertility rate individual, the egg of each hen needs to be marked and stored independently, in addition, the egg of each hen is placed independently by a special hatching string bag during hatching, the confusion with the eggs of other hens is prevented, in the step of selecting the double-ovary individual, the X-ray is adopted for detection when the high-fertility rate individual is detected, in the target group expanding and breeding step, the male-female ratio of establishing a family system for mating is 1: 7-1: 10, in the high-yield performance maintaining and consolidating step, the female chicks with double fallopian tubes are judged and retained for feeding, each chicken needs to wear a wing number and is well recorded in a pedigree, in the high-yield performance maintaining and consolidating step, after 300-day seed retention, the F3 generation is not used as a seed, and only the conventional breeding performance is monitored.
According to the method, in the cultivation process, the double fallopian tubes are screened manually, the double ovaries are screened by X-ray, individuals with degenerated right fallopian tubes and ovaries are removed at high strength, and a new high-yield and high-reproduction laying hen variety with the characteristics of the double fallopian tubes and the double ovaries is cultivated, compared with a foreign high-yield variety, the laying number of 72-week-old laying hens is increased by 12.9%, the total laying weight is increased by 11.8%, the laying rate in a peak period is increased by 5.3%, and the fertilization rate of laying hens is increased by 6.7%.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
