Description

Method for indirectly breeding high-yield Zhedong female goose
Technical Field
The invention relates to a method for indirectly breeding high-yield Zhedong female geese, belonging to the technical field of Zhedong female goose breeding.
Background
The Zhedong white goose is a good variety of the local domestic goose in China, is well known due to the characteristics of early sexual maturity, delicious meat quality and the like, but cannot adapt to large-scale commercial production due to strong nestability and low egg yield. Therefore, the development of the white goose egg yield breeding in Zhedong is an important aspect for the development and utilization of local goose varieties. At present, artificial egg supporting or family booth rotation of male geese is generally adopted to record egg laying and develop egg yield breeding. Although the method improves the egg laying performance to a certain extent, the labor consumption is huge, and the female goose needs to be frightened every day, so that the stress reaction is easily caused. In recent years, research and development are also attempted to develop individual monitoring records of breeding geese, but the recording accuracy is insufficient, the equipment price is high, and the wide application in production is difficult.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the technical problems, the invention provides a method for indirectly breeding high-yield Zhedong female geese, which is simple, reliable, reasonable and accurate in prediction.
The technical scheme is as follows: in order to achieve the purpose of the invention, the technical scheme adopted by the invention is as follows:
a method for indirectly breeding high-yield Zhedong female geese comprises the following steps:
(1) through observing and analyzing egg laying and nestling behaviors of the Zhedong female geese and carrying out linear fitting on the egg laying amount and the nestling times of the Zhedong female geese, a linear relation P = ax + b is obtained, wherein: p is the egg yield of the Zhedong female goose in the whole egg-laying season, x is the nest-taking times of the whole egg-laying season, and a and b are the correlation coefficients obtained by calculation;
(2) selecting the nestling geese when breeding the Zhe Dong female geese, counting the nest-forming times of each female goose in the whole egg-laying season of the nest-forming geese, calculating the estimated egg yield of each goose according to a formula P = ax + b, sorting the eggs according to the egg yield, and selecting and reserving individuals 50% of the first egg yield;
(3) reserving seeds in the second egg-laying season, and continuously carrying out breeding for 3-5 generations to obtain a new high-yield Zhedong female goose strain;
and (3) in the step (1), the Zhedong female goose is the first laying season female goose, and the number of the female gooses is determined to be more than or equal to 400.
The method for selecting the nest-bearing geese in the step (2) comprises the following steps:
the video monitoring system is utilized to record the nestling geese, the geese are found to have the continuous squat for more than 48 hours, the pubic interval is measured, and the geese are confirmed to be the nestling geese when the pubic interval is smaller than 3 cm.
And marking by adopting a method of wearing foot numbers in the process of selecting the nest-bearing geese.
The invention fully utilizes the characteristic of strong nestability of the Zhedong female geese, the nestability is determined to be 100%, and the more the nest-taking times are found, the higher the egg yield is, therefore, the index of the nest-taking times can be utilized to indirectly breed the high-yield Zhedong female geese.
The technical effects are as follows: compared with the prior art, the method is simple and easy to implement, eggs do not need to be held every day, expensive equipment is not needed, only the nesting condition of the goose group needs to be observed and recorded, and a large amount of manpower and financial resources are saved; and the result is reliable, and the bred new variety can effectively improve the egg yield by 5-8.
Detailed Description
The technical solutions of the present invention are further described in detail by the following specific examples, but it should be noted that the following examples are only used for describing the content of the present invention and should not be construed as limiting the scope of the present invention.
Examples
Early detection:
selecting the first female goose in the egg-laying season, determining the number of the female geese to be more than or equal to 400, observing and analyzing the behaviors of laying eggs and nesting of the Zhedong white geese in multiple batches, finding 100% of individuals in the Zhedong white goose group to nest, and linearly fitting the egg yield and the nesting times to obtain a linear relation P =6.41x +7.18 (wherein P is the egg yield of the Zhedong white geese in the whole egg-laying season, x is the nesting times in the whole egg-laying season, and R is the nesting times in the whole egg-laying season2=0.991），x2And (4) the suitability test shows that the predicted result has no significant difference from the test result, and the obtained equation can be completely used for estimating the egg production of the white geese in Zhedong.
On the basis of obtaining the above goose egg yield indirect breeding equation, the invention breeds the Zhedong female goose by the following method:
(1) the female geese transferred into the breeding goose house are worn with foot sizes one by one, and the tightness is required to be proper;
(2) in the laying season, a video monitoring system is utilized to record the nest-in situation of the breeding geese, when the geese crouch continuously for more than 48 hours are found, the pubic interval of the geese is measured, the geese with the pubic interval smaller than 3cm (two fingers wide) are confirmed to be the nest-in geese, the foot size of the geese is recorded, and the result is shown in table 1.
(3) Counting the nest-in times of each female goose in the whole egg-laying season (table 2), calculating the estimated egg yield of each goose according to the formula P =6.41x +7.18, sorting the eggs according to the egg yield, and selecting and reserving 50% of individuals in front of the estimated egg yield; therefore, the A009 and A095 individuals are selected and retained.
(4) And in the second egg-laying season, reserving seeds of 50 percent of individuals such as A009 and A095 before the estimated egg yield in the peak egg-laying period, and continuously carrying out breeding for 3-5 generations to obtain the new high-yield Zhedong white goose strain.
