Bos indicus content is a key predictor of beef eating quality under Meat Standards Australia (MSA)  quality grading scheme. Initially a phenotypic estimate of the proportion of B. indicus was used in the MSA model although more recently thishas been estimated from hump height and carcass weight. The Admixture software was used to develop an estimate of B. indicus content using genomic information. It was demonstrated that B. indicus content could be accurately estimated from SNP genotype data (BB_genotype). This knowledge was used to examine the accuracy of estimating B. indicus content from hump height (BB_hump). The estimation of B. indicus content using BB_hump was found to provide a moderate accuracy of estimating B. indicus percentage.  However, this difference in accuracy  did not translate into substantial differences in the prediction of eating quality under the MSA model.
