Embodiment 1

[0024] Embodiment 1: (comprehensive evaluation method of Jiangshan white goose eggshell quality)

[0025] (1) Determination of the eggshell quality index value of the eggs produced by each individual of the Jiangshan White Goose population to be evaluated: During the peak egg production period of the goose population (that is, when the egg production rate reaches more than 50%), use an eggshell strength tester and The vernier caliper measures and records the values ​​of the four indicators of eggshell strength, blunt end thickness, equatorial thickness and sharp end thickness of the eggs laid by each individual of the goose group to be tested;

[0026] (2) Substitute the measured values ​​of the four indexes of each individual of the goose flock into the comprehensive evaluation index equation, and calculate the eggshell quality evaluation index value of each individual:

[0027] Comprehensive evaluation index = 0.03714 × Q i +0.99221×D i +0.98984×C i +1.01513×R i

[0034] Implementation Case 2: (Comprehensive Evaluation Method for Taihu Goose Eggshell Quality)

[0035] (1) Determination of the eggshell quality index value of the eggs produced by each individual of the Taihu goose population to be evaluated: During the peak egg production period of the goose population (that is, when the egg production rate reaches more than 50%), use an eggshell strength tester and a vernier caliper Respectively measure and record the value of four indicators of eggshell strength, blunt end thickness, equatorial thickness and sharp end thickness of eggs laid by each individual of the goose group to be tested;

[0036](2) Substitute the measured values ​​of the four indexes of each individual of the goose flock into the comprehensive evaluation index equation, and calculate the eggshell quality evaluation index value of each individual:

[0037] Comprehensive evaluation index = 0.03714 × Q i +0.99221×D i +0.98984×C i +1.01513×R i

Abstract

The invention discloses a method for comprehensively evaluating quality of a goose eggshell and belongs to the technical field of poultry breeding. The method is provided on the basis of establishing goose eggshell quality comprehensive evaluation index which is 0.03714*Q1+0.99221*Di+0.98984*Ci+1.01513*Ri. The method comprises the following steps of: (1) measuring four index values of eggshell strength, obtuse end thickness, equator thickness and sharp end thickness of goose individuals to be tested; (2) calculating an evaluation index equation; and (3) selecting individuals of preferable goose parents, and the like. The evaluation index obtained by the method has high relativity with the eggshell measuring index of each individual goose. By the method, the deviation of the traditional single character evaluation is overcome; safety of goose egg products is improved; the breakage rate of the egg products in industrial production is reduced; and incubation effect is improved. The method can be popularized and applied to the field of goose breeding.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for comprehensively evaluating the quality of goose egg shells. technical background [0002] Eggshells are an important natural barrier for poultry and egg products to isolate external bacterial contamination. The quality of eggshells not only directly affects the possibility of poultry eggs being contaminated by external bacteria, the length of storage time and the effect of incubation, but also its vulnerability rate. The level of egg shell also restricts the length of the fresh egg production line and the degree of automation, so the quality of egg shells also affects the safety of poultry egg products to a large extent. Therefore, the evaluation of goose eggshell quality is one of the important foundations in its breeding work, and it is a work with a large investment and a long time, especially when it involves the selection of multiple quality traits of e...
