Dairy cattle breeding for improved milk production traits in cattle
Nucleic acid molecules comprising a SNP site selected from the group consisting of position 1296 of bovine uterine milk protein (UTMP) coding sequence (SEQ ID NO: 1), position 213 of bovine signal transducer and activator of transcription (STAT1) coding sequence (SEQ ID NO: 2), position 8514 of the osteopontin (OPN) gene (SEQ ID NO: 3), or position 1070 of a bovine lectin-like oxidized LDL receptor (OLR1) coding sequence (SEQ ID NO: 4), which SNP indicates a desirable milk production trait in a dairy cattle. Also disclosed are an array or a kit comprising the same, a method for detecting the SNPs, a method for progeny testing of cattle, and a method for selectively breeding of cattle.
