Although this method improves the laying performance to a certain extent, it consumes a lot of manpower and needs to disturb the goose every day, which is easy to cause stress response
Recently, some research has attempted to develop individual monitoring records for breeding geese, but the accuracy of the records is insufficient and the equipment is expensive, making it difficult to be widely used in production

[0017] Early detection:
[0018] Zhedong female geese were selected as the first laying season female geese, and the number of female geese was determined to be greater than or equal to 400. Through observation and analysis of multiple batches of egg laying and nesting behaviors of Zhejiang eastern white geese, it was found that Zhejiang eastern white geese 100% of the individuals in the group nested, and linear fitting was performed on the egg production and the number of nests, and the linear relationship P=6.41x+7.18 was obtained (wherein, P is the egg production of Zhejiang East White Goose in the whole egg production season, and x is The number of nests in the whole laying season, R 2 =0.991), x 2 In the suitability test, there was no significant difference between the predicted results and the test results, which indicated that the obtained equation could be used to estimate the egg production of Zhedong White Goose.
[0019] On the basis of obtaining the indirect bree...

The invention discloses a method for indirect breeding of high-yielding Zhedong female geese, which comprises the following steps: (1) observing and analyzing the egg laying and nesting behavior of Zhedong female geese, and comparing the egg production and nesting behavior of Zhedong female geese The number of times is linearly fitted, and the linear relationship P=ax+b is obtained, where: P is the egg production of Zhejiang East White Goose in the whole laying season, x is the number of nests in the whole laying season, and a and b are the calculated linear fitting Regression coefficient; (2) When breeding female geese in eastern Zhejiang, select the nesting geese, count the nesting times of each female goose in the whole laying season, and calculate the estimated production of each goose according to the formula P=ax+b According to the number of egg production, the top 50% of the individuals with egg production will be selected and retained; (3) After the second egg production season is reserved for seedlings, 3-5 generations of continuous breeding can be carried out to breed high-yielding Zhe A new strain of Dongbai goose. The method of the invention is simple and easy, does not need to carry eggs and expensive equipment every day, saves manpower and financial resources, and has reliable results, and the new variety selected can effectively increase the egg production of 5-8 eggs.
Description
technical field [0001] The invention relates to a method for indirect breeding of high-yielding Zhedong female geese, and belongs to the technical field of Zhedong female geese breeding. Background technique [0002] As an excellent domestic goose breed in my country, Zhedong white goose is well known for its early sexual maturity and delicious meat, but it cannot adapt to large-scale commercial production because of its strong nesting ability and low egg production. Therefore, it is an important aspect to develop and utilize local goose breeds to carry out egg production breeding of Zhedong white goose. At present, artificial egg laying or male geese are usually rotated in small compartments in the family to record egg production and carry out breeding for egg production. Although this method improves egg production performance to a certain extent, it consumes a lot of manpower and needs to disturb the goose every day, which is easy to cause stress response. Recently, som...
