Embodiment 1

[0029] A method for conservation and breeding of central Yunnan cattle, comprising:

[0030] S1. Breeding of Dianzhong Cattle

[0031] In the main breeding area of ​​Dianzhong cattle, large-scale selection of large cattle is carried out.

[0032] S2. Dianzhong Cattle Conservation Breeding

[0033] The cattle that meet the basic requirements for calculating the score among the breeding selection cattle are established to establish the basic cattle group, and are raised and bred in the basic cattle group. During the breeding process, the second-generation cattle with high calculated scores are selected to establish the second-generation cattle herd, and the cattle with calculated scores lower than the basic requirements are eliminated to the observation herd.

[0034] S3. Dianzhong Cattle Breeding

[0035] The bulls from the secondary cattle herd were fed and bred with cow A in the secondary cattle herd and cows B-X of other elite cattle breeds to establish the Dianzhong catt...

Embodiment 2

[0047]Based on the Dianzhong cattle breeding method described in Example 1, the method of transferring the cattle whose calculated scores meet the requirements to the Dianzhong cattle breeding herd or the Dianzhong cattle improved cattle group B-X is as follows: The required cattle are transferred to the breeding observation base for at least 2 months of feeding, and the observation cattle whose calculated score Z continues to meet the breeding requirements are transferred to the Dianzhong cattle breeding herd or the Dianzhong cattle improved cattle herd B-X.

[0048] This method is the error correction mechanism of the present invention, which can return the high-quality cattle that were screened to the observation herd due to other factors in the screening process to the breeding herd after meeting the error correction conditions, effectively improving the screening rate of high-quality cattle , Improve the income of species conservation and breeding. This method mainly take...

Embodiment 3

[0050] Based on a method for preserving and breeding Dianzhong cattle described in Example 1, the method for transferring the cattle whose calculated scores meet the requirements to the Dianzhong cattle breeding herd or the Dianzhong cattle improved cattle group B-X is as follows:

[0051] (1) Taking the time t as the X-axis and the calculated score Z as the Y-axis, establish Z-t curves in the coordinate system for the cattle in the observed herd.

[0052] (2) Calculate the curvature of the Z-t curve of each cow separately.

[0053] (3) When the curvature of the Z-t curve of the three consecutive score calculation periods of the cow is all in the top 10%, and the calculated score Z meets the breeding requirements, the observation cow will be transferred to the Dianzhong cattle breeding herd or the Dianzhong cattle improvement Herd B-X. At this time, the period for obtaining the calculated score of each cow is 15-20 days.

[0054] This method is another error correction mecha...

Abstract

In order to overcome the defects in the prior art, the invention provides a Yunnan middle cattle breed conservation and breeding method which comprises the following steps: S1, carrying out large-range large cattle breed selection; S2, establishing a basic cattle herd for the cattle meeting calculation score basic requirements; selecting the second-generation cattle with the high calculation score to establish a second-generation cattle herd, and eliminating the cattle herd with the calculation score lower than the basic requirements to an observation cattle herd; S3, raising and breeding bulls in the second-generation cattle herd with cows A in the second-generation cattle herd and cows B-X of other excellent cattle breeds, carrying out preferential reservation, and eliminating the rest of the cows to the observation cattle herd; S4, numbering and raising the cattle in the observation herd, obtaining the calculation scores of all the cattle regularly, preferentially transferring the cattle to a breeding cattle herd of the Yunnan middle cattle or an improved cattle herd B-X of the Yunnan middle cattle, and transferring the cattle which do not meet the requirements to a beef cattle feeding area for feeding. According to the method, raising result evaluation is carried out on the breed conservation and breeding cattle based on a calculation evaluation mode, stability is high, and the obtained cattle are good in quality.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for breeding conservation and breeding of central Yunnan cattle. Background technique [0002] Dianzhong cattle, which were listed in the National Catalog of Livestock and Poultry Genetic Resources in 2010, belong to the meat-serving and dual-purpose cattle. Dianzhong yellow cattle are distributed in central Yunnan, and are mainly produced in 6 counties (cities) including Shuangbai, Chuxiong, Dayao, Wuding, Lufeng, and Nanhua in Chuxiong Prefecture, and 4 counties (cities) including Yao'an, Yuanmou, Mouding, and Yongren. It is distributed in the dam area, half mountainous area and mountainous area, and is raised from the low heat valley at an altitude of 556m to the alpine mountainous area at an altitude of 3657m. Dianzhong cattle have stable genetic performance, strong physique, well-proportioned development, small body and large strength, heat and labor r...
