Results

Base line data for all 'Challenge' steers was collected while handling the animals in the NT DPIF Quarantine Paddock. This data included liveweight, body condition, hip height, fat score and dentition. To be able to track the progress of the steers during the 'Challenge', quarterly recording of the data as seen in Table 1 will occur for the duration of the project.

Liveweight (target: 575 kg at turnoff)

A liveweight target of 575kg has been set for the challenge steers. It is based on a 200kg six month old weaned steer growing at 0.5 kg per day to weigh 575kg at 2.5 years of age at turnoff.

Liveweight gain (target: 0.5 kg/day)

Within the Meat Standards Australia (MSA) system it has been noted that a faster growth rate will produce a heavier carcase without increasing ossification levels. By calculating liveweight gain over the 'Challenge' and comparing it with carcase feedback further insights may be gained into this relationship.

Fat depth (target: 6.0 mm at turnoff)

Essential for meeting MSA standards. Measuring fat depth at the p8 site has been correlated to fat depth over the ribs. This measurement will provide an interesting insight as to how fat is laid down as the steers grow and will be crucial in comparing live and carcase fat depth results.

Body condition (target: 5-6 {1-9 scale})

Indicator to determine energy reserves of the animal. Ensuring that animals have ample energy and protein as they grow helps to manage ossification.

Body Condition Score

Dentition

Incisor Teeth Present

Hip height

To monitor skeletal growth of animals and aid in determining growth and fattening potential of an animal. It will be interesting to compare data with carcase feedback at the end of the 'Challenge' for any additional insights into cattle growth and meeting of abattoir carcase specifications.

Remote Livestock Management System (RLMS)

In addition, a Remote Livestock Management System (RLMS) has been installed to produce web based performance for the steers.
