Title: | Valuing DNA tested bulls for commercial beef production | Contributor(s): | Wood, B J (author); Van Der Werf, Julius Herman (author) ; Parnell, P F (author) | Publication Date: | 2004 | DOI: | 10.1071/AR03268 | Handle Link: | https://hdl.handle.net/1959.11/2796 | Abstract: | This paper quantifies the benefits of using a sire genotyped for a single recessive gene in a commercial beef herd. A modified gene-flow method was used to account for changing allele frequency over time. The benefits to a commercial breeder of using a genotyped sire were highest when initial allele frequency was moderate and when the sire was used in a self-replacing herd that had increased allele frequency over time. An example of the thyroglobulin gene affecting marbling in beef cattle was used. The value to a self-replacing herd of a sire homozygous for the favourable allele of the thyroglobulin gene was shown to be up to $338 more than of an ungenotyped sire, in a population where the initial gene frequency was 0.3 and the genotype accounted for 0.5 standard deviations of phenotypic variation. | Publication Type: | Journal Article | Source of Publication: | Australian Journal of Agricultural Research, 55(8), p. 825-831 | Publisher: | CSIRO Publishing | Place of Publication: | Australia | ISSN: | 1444-9838 0004-9409 1836-5795 1836-0947 |
