The application relates to the technical field of molecular markers, and particularly discloses purposes and liquid-phase chips, methods and applications of a beef cattle molecular marker combination, the purposes comprising: being used for genotyping, breed identification and pedigree analysis of Simmental cattle, Charolais cattle, Limousin cattle, Hereford cattle, Angus cattle, Piedmontese cattle, Jaxian red cattle and Nanyang cattle; the beef cattle molecular marker combination comprising 3987 SNP sites; physical positions of the 3987 SNP sites are determined based on whole genome sequence alignment of a bovine reference genome ARS-UCD1.2; wherein the 3987 SNP sites are shown in Table 1. The application can be used for genotyping, breed identification and pedigree analysis of Simmental cattle, Charolais cattle, Limousin cattle, Hereford cattle, Angus cattle, Piedmontese cattle, Jaxian red cattle and Nanyang cattle.

The invention discloses a bovine 30K liquid phase chip and application thereof, and belongs to the field of molecular biology and biological chips. The liquid phase chip comprises a probe combination for detecting 30715 SNP (Single Nucleotide Polymorphism) loci, and the loci are obtained by performing whole genome re-sequencing and screening on milk and meat dual-purpose type Simmental cattle varieties such as Monebela cattle, Freevey cattle, Simmental cattle and the like. The sites integrate paternity test sites, genetic defect gene sites, variety identification sites and breeding target functional sites related to important economic traits such as milk yield and meat traits. The chip has high stability, high detection rate and high accuracy, can be applied to paternity test, genetic defect screening, variety identification and molecular breeding of milk and meat dual-purpose type Simmental cattle varieties, and is particularly suitable for the requirements of small and medium-sized breeding enterprises on cost-sensitive accurate genetic typing; and an efficient technical tool is provided for improved variety breeding of the milk-meat dual-purpose type Simmental cattle variety.

The present application relates to the field of animal genetic breeding and intelligent animal husbandry, in particular to a crossbreeding improvement method for Simmental cattle, comprising: obtaining whole genome sequence data, phenotypic data and target area environmental climate time series data of a target population; inputting the three types of data into a pre-trained multi-modal dynamic model, extracting features and quantifying the output of recessive genetic load index; judging the relationship between the index and the preset safety threshold; when the index is lower than the safety threshold, generating a first selection scheme based on a pre-constructed deep reinforcement learning model, with the goal of maximizing the intergenerational genetic progress rate of production performance; when the index is higher than or equal to the safety threshold, generating a second selection scheme with the goal of maximizing genetic distance; the present application realizes the dynamic balance between short-term improvement efficiency and long-term breeding safety.
