Embodiment 1

[0014] Selected 156 female ducks of Gaoyou ducks hatched in late April for the experiment, and divided them into 3 groups of 52 ducks for the experiment. The first group was raised normally without any treatment; At the peak egg stage, draw 5ml of blood from the wing root vein of each duck, mark it, put it into a sterile plastic test tube with anticoagulant preservation solution, store them at 4±1°C, and wait for 10 days to return The preserved blood is reinfused back into the duck accordingly. The third group, in late August, when Gaoyou ducks entered the peak egg production period, 10 ml of blood was drawn from the wing root vein of each duck, marked, and put into a sterile plastic test tube with anticoagulant preservation solution. , They were preserved at 4±1°C, and the preserved blood was transfused back into the duck body correspondingly after 10 days. The experimental results show that: the first group produces 8550 eggs per year, and the average annual egg production ...

Abstract

The present invention provides a method for increasing double-yolk egg laying rate of Gaoyou duck by means of self-body blood transfusion. Said method includes the following steps: in the laying season of Gaoyou duck drawing 5-10 ml of blood from wing root vein of every Gaoyou duck, marks its, placing the blood into a sterile plugged plastic test tube in which the anticoagulant preservative fluid is contained, storing them below 4 plus or minus 1 deg.C, after 10 days, injecting said blood into correspondent duck body interior.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for increasing the production rate of Gaoyou duck double-yolk eggs through autologous blood transfusion. Background technique [0002] Gaoyou Duck (Anatis Domesticae Caro, Varity: Gaoyou) is native to Gaoyou, Jiangsu, and distributed in Lixiahe area, Jiangsu Province. The male duck is larger in size, with broad back, broad shoulders, deep chest, dark green feathers on the head and upper part of the neck, brown reed feathers on the back, waist, and breast, black tail feathers, and white belly; female ducks have long necks, tight feathers, and deep breasts. , well developed hindquarters. The whole body feathers are light brown, like sparrow feathers, with fine patterns, and the main wing feathers are blue and black. The egg production is about 100 in spring and 60 in autumn, with an average annual egg production of 140-160 eggs and an egg weight of 75.9 grams. ...
