Dr. Wurtz studies a variety of topics related to both animal welfare and human health. For farm animals, he examines methods to assess their mobility and behavior, such as testing walking ability in chickens and capturing animal behavior using technology. He is committed to finding effective, efficient ways for farmers to monitor and improve the living conditions of their livestock. In the realm of human health, he explores potential treatments for diseases like prostate cancer, specifically looking at how a compound from olive oil might affect cancer cells and contribute to new therapeutic options.
Key findings
In a study of 345 broiler chickens, the average latency-to-lie for chickens with better walking ability was about 14 seconds compared to 129 seconds for those with poorer mobility.
The systematic review of 108 studies on animal behavior indicated a gap in validation in real-world farming situations, especially in understanding the behaviors of pigs.
Laying hens jumping from heights of 41 cm land with an average force of about 81 newtons, while jumping from 61 cm lands with an average force of around 107 newtons, highlighting the importance of housing design for hen welfare.
Hydroxytyrosol treatment at 80 micromoles per liter caused increased cell death and damage to human prostate cancer cells, indicating its potential as an anti-cancer agent.

Research Note: Testing the validity of latency-to-lie tests without water for objective on-farm assessment of walking ability of broiler chickens.

Poultry science
Wurtz K, Rasmussen S, Riber A
Plain English This study explored a new method for assessing how well broiler chickens can walk without using water, which is a practical challenge on farms. They tested 345 chickens and found that the time it took for chickens to sit (latency-to-lie) was closely linked to their walking ability, with longer sit times indicating worse walking skills. On average, chickens with a higher gait score (indicating better walking ability) sat down in about 14 seconds, while those with a lower score took about 129 seconds, showing a clear trend that matters for animal welfare and farming efficiency.
Who this helps: This helps farmers and veterinarians monitor the health and mobility of chickens more effectively.
Recording behaviour of indoor-housed farm animals automatically using machine vision technology: A systematic review.

PloS one
Wurtz K, Camerlink I, D'Eath RB, Fernández AP, Norton T +2 more
Plain English This study looked at how technology can automatically track the behaviors of farm animals to improve animal welfare and production efficiency. Researchers reviewed 108 studies that focused on how well different types of cameras could record animal behaviors, finding that most research involved pigs and looked at behaviors like movement, aggression, and how animals used their space. Many studies used the same methods without building on previous findings, and the smaller sample sizes indicated a need for better validation in real-world farming situations.
Who this helps: This helps farmers and researchers improve animal care and productivity.
Plain English This study looked at how much force laying hens create when they jump and land from different heights in non-cage housing. Researchers found that hens jumping from 41 centimeters land with an average force of about 81 newtons, while those jumping from 61 centimeters land with an average force of around 107 newtons. Understanding these impacts is important because it helps ensure the hens' welfare and prevents injuries, which can also affect egg production.
Who this helps: This research benefits farmers and egg producers by promoting hen welfare and minimizing injuries.
Hydroxytyrosol promotes superoxide production and defects in autophagy leading to anti-proliferation and apoptosis on human prostate cancer cells.

Current cancer drug targets
Luo C, Li Y, Wang H, Cui Y, Feng Z +7 more
Plain English This study looked at how hydroxytyrosol, a compound found in olive oil, affects human prostate cancer cells. Researchers discovered that treating these cancer cells with hydroxytyrosol led to increased cell death and damage to cellular processes, specifically after using a concentration of 80 micromoles per liter. This discovery is important because it highlights hydroxytyrosol's potential as an anti-cancer agent, opening the door for more research on its use in cancer treatment.
Who this helps: Patients with prostate cancer may benefit from future treatments involving hydroxytyrosol.
Selective metal-cation recognition by [2.2]ferrocenophanes: the cases of zinc- and lithium-sensing.

Otón F, Ratera I, Espinosa A, Wurtz K, Parella T +3 more
Plain English This study explored new chemical compounds called [2.2]ferrocenophanes to see how well they can detect specific metal ions like zinc and lithium. The researchers found that these compounds bind very well to zinc (Zn²⁺) ions and have an even stronger attraction to lithium (Li⁺) ions. This is important because it means these compounds could be used in various applications, such as improving sensors for detecting these metals in medical or environmental settings.
Who this helps: Patients, doctors, and industries that need precise metal detection.
