|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:||Melbourne, Australia||ISSN:||0004-9409||Field of Research (FOR):||070201 Animal Breeding||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Other Links:||http://nla.gov.au/anbd.bib-an2856653||Statistics to Oct 2018:||Visitors: 163
