Better detection of calving events for improved productivity

The Calf 48 hour project is evaluating and enhancing technologies to detect parturition events in cattle. The project aims to improve diagnosis of causes of calf loss in extensive grazing systems.

Led by CQUniversity Australia, in partnership with the Northern Territory Government’s Department of Industry, Tourism and Trade (DITT), the focus of this Meat and Livestock Australia (MLA) funded project is on calf losses that occur in the first two days of life.

Researchers believe most deaths happen in this critical timeframe but the exact reasons remain unknown.

Consequently, the broad objectives of the Calf 48 hour project are to:

  • better understand why and how some calves survive
  • develop sensor systems that can be used by producers to monitor their own cattle and determine the causes of losses in their specific conditions.

The expected outcomes of the Calf 48 hour project are direct improvements in the welfare of animals and improvements on productivity of our cattle industry through increased survival rates.

Technology for remote locations

Beef cattle producers in northern Australia face a massive challenge in monitoring and, if needed, intervening during calving, simply because nobody can know for sure when and where a breeder is during delivery in such remote locations.

During phase 1 of this project, CQUniversity researchers are evaluating a number of sensor systems to improve detection of location and behaviour data of cattle during calving (figure 1).

Improving the performance of these technologies will enable producers to know when cows calve, even in extensive and remote locations.

Phase 2 will be conducted on a large property on the Barkly Tablelands in collaboration with the DITT team where researchers from across northern Australia will combine forces.

The chosen area is representative of the extensive grazing systems in the north, where heat, distance to water, predation and a range of other variables are ongoing challenges to animal welfare and productivity.
