Genomics is widely used in Australia to help breed the type of cow farmers want to milk. The factsheet, video and links will help you understand the benefits.
Genomics is the large-scale use of DNA information to predict the potential performance of bulls and cows.
As an industry, we aspire to double the rate of genetic gain in Australia through the use of genomic selection.
Genomics is delivering significant benefits to the Australian dairy industry through:
- improving the section of young bulls to progeny test by AI companies;
- providing more reliable info for younger bulls, i.e. for traits like fertility; and
- selecting superior females at a younger age to breed replacement heifers.
For more info on how genetics works, check out this short video:
Genomics has been available in Australia since 2011, genomic information is routinely used to calculate genomic Australian Breeding Values - ABV(g)s for dairy sires and also for females. The analysis is primarily don e from a hair sample, allowing animals to be tested from a very young age.
Read the Genomics and your dairy herd brochure to learn more.
Cow ABV(g)s provide you with more reliable information to help breed the type of cows you want. Cow ABV(g)s estimate a female’s genetic merit for breeding the next generation. This means the information is useful when making decisions about joining, flushing, selling and purchasing both the individual and her progeny.
Your Cow ABV(g) report provides breeding values using DNA data alongside the conventional pedigree and performance information.
More reliability means more confidence making breeding decisions. The reliability of cow ABV(g)s is significantly greater than conventional breeding values. The genomics adds the equivalent of 7 lactations to the reliability of the cow’s breeding value.
