Scientists use ‘genomic time-travel’ to discover new genetic traits in African cattle

Animal scientists have announced the discovery of a new set of detailed genetic markers and information in African cattle that are associated with valuable traits, such as heat and drought tolerance, the capacity to control inflammation and tick infestations, and resistance to livestock diseases. The research team wanted to learn how – after spending thousands of years confined to a shifting patchwork of sub-regions in Africa – local cattle rapidly evolved with traits that allowed them to thrive across the continent, not dissimilar to parts of northern Australia…Read More

Weekly genetics review: How long will the influence of your 2020 sire purchases last in your herd?

This year’s sire purchases will have an influence over a herd potentially until 2030, genetics editor Alastair Rayner writes this week. “Moreover the last three generations of sires determine 87pc of the genetics within a calf crop – so genetic improvement is long-term, and needs to be considered in order to change direction. Its not an easy change,” he writes…Read More

2020 bull selling season setting some unbelievable benchmarks

With a month or so still left to play out, the 2020 spring bull selling season is rapidly emerging as an era-defining benchmark for the seedstock industry, by which all bull sales will be measured for years, if not decades to come. What has set the 2020 season apart is not so much a string of breed record prices (although a few breed records have in fact already been set this year) but the sheer depth and determination of buying support…Read More

Breeding cattle for greater environmental efficiency

Breeding for environmental efficiency and breeding for economic efficiency are highly complementary, this study compiled by Southern Beref Technology Services suggests. In both cases, fertility is paramount; after all, a cow in the breeding herd should raise a live calf each year and failure to do so makes her a drain on resources…Read More

Weekly genetics review: New opportunities to capture data on farm

This week’s column looks at the work that Central Qld Uni and DataMuster have been doing to use Walk over Weighing technology to capture more accurate, frequent and reliable data. In extensive cattle regions where data collection is challenging, this technology opens up possibilities beyond management to record traits that can lead to better genetic improvement and fertility measures. Its an exciting time and one that has immense possibilities…Read More
