This is a repository for beef cattle genomics data. It includes a collection of sequence data from QAAFI's Centre for Animal Science (CAS) genomics research. Increasing the rate of genetic gain of breeding programs in beef cattle is a key component of maintaining a viable competitive beef cattle industry. Advances in the field of DNA sequencing has enabled experiments that link the whole or transcribed genome of livestock to phenotypic differences between animals. We will aim to utilise this new technology to address a key problem in northern Australian beef production systems. The lower reproductive efficiency of Brahman and other Bos indicus-influenced beef breeds that predominate in Queensland is in part genetically determined. The selection of herd bulls that will sire female herd replacements with high fertility is therefore a crucial strategy to lift the productivity of Queensland beef herds. We are embarking on a series of experiments that looks at the transcribed regions of the genome which will identify genes that are linked to differences in fertility of beef cattle. Such experiments generate large amounts of sequence data . Sequencing data.
