Summary
Foetal and calf losses between confirmed pregnancy and weaning have been identified as a major problem limiting beef production in northern Australia. Heat load has been identified as a possible factor contributing to calf loss, with the hypothesis that modification of the environment could reduce heat gain and elevate the heat dissipation to protect calves and heifers from heat load. This project worked with a commercial property to pilot providing paddock shade and evaluate its effect on reducing the occurrence of calf wastage.
Objectives
This study aimed to evaluate the effectiveness of providing paddock-shade shelters on reducing the occurrence of calf loss in a population of commercial beef heifers.
Key findings
This project highlighted the significant impact calf loss is having on northern beef businesses. In this study on this property, provision of artificial shade near watering points was not an effective method at consistently reducing the occurrence of foetal and calf loss and did not result in any other production gains. Whilst there are potential animal welfare benefits gained by the provision of artificial shade to open grazing lands, due to the high costs associated with their installation and ongoing maintenance, it is unlikely to be profitable.
Benefits to industry
The results from this study highlighted the impact calf loss is having on the productivity of northern beef businesses, and that a multidisciplinary and evidence-based approach is needed to tackle the issue.
MLA action
MLA continues to invest in research, development, and adoption activities to increase calf survival and reproductive efficiency in northern Australia.
Future research
Further research was suggested to investigate the causes of calf loss and the impact of daily environmental conditions, as well as develop practical and cost effective strategies producers can implement to increase calf survival.
