Polymorphisms in fatty acid binding protein 4 (“FABP4”) gene and their associations with measures of marbling and subcutaneous fat depth in beef cattle
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 genes encoding fatty acid binding proteins 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 ribeye area (REA) per hundred weight hot carcass weight (cwt-HCW) as compared to the general population of bovine animals, comprising:
(a) obtaining a biological sample from said bovine animal, said biological sample comprising nucleic acids encoding the bovine fatty acid binding protein 4(“FABP4”) gene from said bovine;
(b) detecting in said nucleic acids the presence of a C in one or both alleles of the FABP4 gene at position corresponding to position 7516 of SEQ ID NO: 1; and
(c) correlating the presence of the nucleic acid content of (b) with a higher ribeye area (REA) per hundred weight hot carcass weight (cwt-HCW) in said bovine animal.
2. The method of claim 1 further comprising sub-grouping animals according to genotype, wherein the animals of each sub-group have the same polymorphism in the FABP4 gene, said method comprising:
(a) determining the genotype of each animal to be sub-grouped by determining the presence of a single nucleotide polymorphism in the FABP4 gene according to the method of claim 1 , and
(b) segregating individual animals into sub-groups depending on whether the animals have, or do not have, the single nucleotide polymorphism of interest in the FABP4 gene.
