Embodiment 1

[0014] 1. Determine the response type according to the degree and speed of the massage stimulation response, and carry out objective scoring. There are four types of response. The first type is represented by 0. The massage response is: no response or slow response to massage stimulation for more than 60 seconds, no ejaculation ; The second type is represented by 1, and its massage response is: fast response to massage stimulation, and there is no ejaculation within 60 seconds; the third type is represented by 2, and its massage response is: slow response to massage stimulation , needs massage stimulation for more than 60 seconds to respond, but ejaculate; the fourth type is represented by 3, and its massage response is: fast response to massage stimulation, response to massage stimulation less than 60 seconds, and ejaculation;

[0015] 2. At the beginning of the breeding season, the male goose 1’s genitals were stimulated by dorsal and abdominal massage, and the time from the ...

Abstract

The invention relates to a method for predicting the fertility of ganders. The method comprises the steps as follows: 1, determining response types according to the massaging stimulation response degree and speed, and carrying out objective scoring on the ganders; 2, in the beginning of a breeding season, stimulating the genital organs of the ganders by adopting a back and belly type massaging method, recording the time from massaging stimulation to ejaculation reflection at the same time, and collecting seminal fluids; 3, determining the individuals with the massaging stimulation scores of 2 and 3 according to different responses of the individuals on the massaging stimulation process as the qualified ganders; and 4, measuring the seminal fluid quantity, the seminal fluid concentration and the sperm activity of the ganders according to the seminal fluid quality. According to the method, the ganders are early selected according to stronger positive correlation of the early massaging stimulation response and the seminal fluid quality of the ganders in the whole breeding season, so that the gander selection accuracy is improved and the breeding efficiency is improved.

Description

1. Technical field [0001] The invention relates to a method for distinguishing the reproductive ability of male poultry, in particular to a method for predicting the reproductive ability of male geese. 2. Background technology [0002] The quality of semen varies greatly among different individuals of geese, and it is difficult to distinguish male geese from the appearance of geese in production practice. In production practice, male geese are selected mainly by observing the size and color of their reproductive organs and the quality of their semen. There are certain defects in this method. The quality of goose semen is unstable, that is to say, individuals with good semen quality at the beginning of the breeding season may not necessarily still have good performance in the middle and late stages of breeding. 3. Contents of the invention [0003] The purpose of the present invention is to provide a method for predicting the reproductive capacity of male geese. This metho...
