Problems solved by technology

Due to the large number of dairy cows in modern cattle farms, complex inbreeding coefficient calculations are required for artificial insemination to screen frozen semen. Manual calculations take a long time, are inefficient, and have high error rates, making it difficult to meet the needs of management and production. It is particularly important to calculate the inbreeding coefficient and the information management of dairy cow breeding by means of computerized information
Due to artificial factors, the traditional calculation of inbreeding coefficient of dairy cows, pedigree relationship management is not clear, resulting in low calculation accuracy

Embodiment Construction

[0037] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] Please see attached figure 1 Shown, a kind of dairy cow mating method based on the inbreeding coefficient calculation model, the method at least includes the following steps:

[0039] Step 1: Create and manage a database of dairy breed information, recording the performance of each breed.

[0040] Step 2: Under the existing strain type, create and maintain and manage the family information of the strain.

[0041] Step 3: Establish a bull electronic information database under the corresponding family tree.

[0042] Step 4: Establish an electronic file database of breeding cows to manage the information of breeding cows used to breed bulls so as to maintain the information of breeding cows.

[0043] Step 5: Carry out informatization management on the existing dairy cows in the cattle farm to form an electronic file information database, and the s...

Abstract

The invention discloses an inbreeding coefficient calculation model-based dairy cow hybridization method. The method comprises the following steps of: recording information of each dairy cow through abreeding bull electronic document database and a breeding cow electronic document database, wherein a database table structure comprises detailed information such as breeding bull numbers, breeding bull names, fathers, mothers, families, strains, dates of birth, places of birth, bodily forms, TPI and performance indexes; and when pairing is started, implanting the numbers of to-be-paired dairy cows and the numbers of sperm freezing bulls by an information system, automatically pairing and combining the sperm freezing parameters of each cow and each bull one by one by a computer system, reading a family tree relationship of the paired dairy cows in each group of pairing, constructing an electronic family tree graph, and processing data by utilizing an inbreeding coefficient calculation model so as to obtain an inbreeding coefficient of the combination. According to the method, systematic processing of large data volume can be rapidly and correctly carried out, so that unnecessary humanlabor can be greatly decreased, the correctness of calculated values can be ensured and the processing speed can be improved.

Description

technical field [0001] The invention relates to the field of dairy cow reproduction, in particular to a method for breeding cows based on an inbreeding coefficient calculation model. Background technique [0002] The inbreeding coefficient is an important basis for breeding dairy cows, and the selection of breeding frozen semen is based on the inbreeding coefficient. Due to the large number of dairy cows in modern cattle farms, complex inbreeding coefficient calculations are required for artificial insemination to screen frozen semen. Manual calculations take a long time, are inefficient, and have high error rates, making it difficult to meet the needs of management and production. It is particularly important to calculate the inbreeding coefficient and manage the information of dairy cow breeding by means of computerized information. Due to artificial factors, the traditional calculation of dairy cow inbreeding coefficient is not clear in the management of pedigree relat...
