In the world of rabbit farming, transport is a critical yet often overlooked aspect that can significantly impact the welfare of these animals. A recent study published in *Frontiers in Veterinary Science* (translated to *Frontiers in Veterinary Medicine*) sheds light on how space allowance, container height, and thermal conditions during transport affect the welfare of fattening rabbits. Led by A. Contreras-Jodar from the Institute of Agrifood Research and Technology (IRTA) in Monells, Spain, this research offers valuable insights that could reshape industry practices and improve animal welfare standards.
The study involved 900 rabbits subjected to various conditions, including three different space allowances (121, 150, and 191 cm²/kg), two container heights (20 and 35 cm), and four thermal environments ranging from 21.4 °C to 33.5 °C. The goal was to assess the combined effects of these factors on the rabbits’ welfare during simulated transport.
One of the most striking findings was the severe impact of high temperatures. “We had to stop the trial at 33.5 °C after just five hours due to the severe compromise in the rabbits’ welfare, especially those in the lower space allowances and higher container heights,” Contreras-Jodar explained. This highlights the critical need for careful management of thermal conditions during transport to prevent heat stress and ensure animal welfare.
The study also revealed that lower temperatures increased the risk of hypothermia, while higher temperatures exacerbated hyperthermia, particularly in rabbits with less space. Interestingly, the height of the container did not affect hypothermia but did influence the risk of hyperthermia under warmer conditions. “This suggests that while space allowance is crucial, the height of the transport container also plays a role in managing thermal stress,” Contreras-Jodar noted.
Body weight loss varied significantly with thermal state, with rabbits experiencing hyperthermia losing the most weight. This finding underscores the importance of maintaining optimal thermal conditions to minimize stress and weight loss during transport.
One of the most innovative aspects of the study was the use of thermographic imaging to assess thermal stress non-invasively. The researchers found a strong correlation between rectal temperature and temperatures measured in the lacrimal and ear regions, validating thermography as a reliable tool for monitoring rabbit welfare.
From a commercial perspective, these findings have significant implications. Optimizing transport conditions can lead to healthier, more robust rabbits, ultimately improving productivity and profitability for farmers. “By understanding and mitigating the stressors during transport, we can enhance the overall welfare of the animals and ensure better outcomes for the industry,” Contreras-Jodar said.
The study also supports the adoption of non-invasive monitoring techniques, which can streamline welfare assessments and reduce handling stress for the animals. This could be a game-changer for the industry, allowing for more efficient and humane management practices.
As the agricultural sector continues to evolve, research like this is crucial for driving innovation and improving standards. The findings from Contreras-Jodar’s study not only highlight the importance of optimizing transport conditions but also pave the way for more sophisticated and compassionate approaches to animal welfare. By embracing these insights, the industry can take significant strides towards a more sustainable and ethical future.
