Abstract
The present invention provides a method of genotyping bovine for improved milk production traits by determining the DGAT1 genotypic state of said bovine, wherein the DGAT1 gene and polymorphisms within said gene have been found to be associated with such improved milk production traits.
Claims14
A method of identifying a bovine, or sample derived from said bovine, with a nucleic acid composition indicative of increased milk volume production in said bovine, the method comprising the steps of:
- (a) providing nucleic acids from said bovine, or a sample derived from said bovine where said sample comprises nucleic acids from said bovine;
- (b) detecting, in said nucleic acids, the presence of nucleotides G and C at positions 6829 and 6830 respectively in SEQ ID NO:
- 1;
- and
- (c) identifying said bovine or said sample with nucleotides G and C at positions 6829 and 6830 respectively in SEQ ID NO:
- 1 as one that possesses a nucleic acid composition indicative of increased milk volume production.
A method of identifying a bovine, or sample derived from said bovine, with a nucleic acid composition indicative of decreased milk volume production in said bovine, the method comprising the steps of:
- (a) providing nucleic acids from said bovine, or a sample derived from said bovine where said sample comprises nucleic acids from said bovine;
- (b) detecting, in said nucleic acids, the presence of nucleotides A and A at positions 6829 and 6830 respectively in SEQ ID NO:
- 1;
- and
- (c) identifying said bovine or said sample with nucleotides A and A at positions 6829 and 6830 respectively in SEQ ID NO:
- 1 as one that possesses a nucleic acid composition indicative of decreased milk volume production.
