Polymorphisms in mitochondrial transcription factor A (“
View Patent ↗The physiological regulation of intake, growth and energy partitioning in animals is under the control of multiple genes, which may be important candidates for unraveling the genetic variation in economically relevant traits in beef production. The present invention relates to the identification of single nucleotide polymorphisms (SNPs) within the bovine gene encoding mitochondrial transcription factor A (“TFAM”) and their associations with economically relevant traits in beef production. The invention further encompasses methods and systems, including network-based processes, to manage the SNP data and other data relating to specific animals and herds of animals, veterinarian care, diagnostic and quality control data and management of livestock which, based on genotyping, have predictable meat quality traits, husbandry conditions, animal welfare, food safety information, audit of existing processes and data from field locations.
1. A method for identifying a bovine animal having a higher marbling score (MBS), thicker subcutaneous fat depth (SFD), or a combination thereof said method comprising:
(a) obtaining a biological sample from said bovine animal, said biological sample comprising nucleic acids encoding the bovine transcription factor A (“TFAM”) gene from said bovine;
(b) detecting in said nucleic acids the presence of at least one of:
(i) a C in both alleles of the TFAM gene at position corresponding to position 379 of SEQ ID NO: 1;
(ii) a C in both alleles of the TFAM gene at position corresponding to position 387 of SEQ ID NO: 1;
(c) correlating the presence of the nucleic acid content of (b) with a higher marbling score, thicker subcutaneous fat depth (SFD), or a combination thereof in said bovine animal.
