The British Society of Animal Science is delighted to announce May Allan, a student from Scotland’s Rural College (SRUC), as the winner of the BSAS Undergraduate Thesis of the Year 2024 award. Her innovative research explored the potential of probiotic supplementation in managing Cryptosporidium infections in young calves, a subject with significant implications for livestock health and sustainable farming practice.

Background and Inspiration

May’s passion for animal science stems from a lifelong interest in animal welfare and curiosity about using science to address real-world challenges. Her desire to contribute to livestock health, particularly in rural farming communities, inspired her to pursue a degree in animal science.

"I believe that enhancing animal health plays a key role in boosting productivity and promoting sustainability in agriculture," May explained. This commitment to meaningful contributions in the field eventually led her to a groundbreaking research topic with direct practical applications for the livestock industry.

Tackling Cryptosporidium: Choosing the Right Thesis

Cryptosporidium, a common parasite in young calves, causes severe diarrhoea, poor growth rates, and significant economic losses for farmers. Despite being untreatable with antibiotics, these drugs are often used to address secondary bacterial infections caused by the weakened immune systems of infected calves.

“Antimicrobial resistance is a growing concern, and overusing antibiotics exacerbates this global challenge,” May noted. To address this issue, her thesis investigated whether probiotics—natural supplements known for supporting gut health—could offer a sustainable alternative to antibiotics in combating Cryptosporidium. Her findings hold the potential to revolutionise livestock management practices.

Key Findings from May’s Thesis

In a six-week trial conducted on a dairy farm, May discovered that calves receiving probiotic supplementation experienced substantial improvements:

• Reduced diarrhoea severity
• Increased weight gain
• Enhanced milk consumption
• More stable body temperatures

These results suggest that probiotics can strengthen the gut microbiome, improve immune responses, and mitigate the impact of Cryptosporidium infections. Beyond benefiting calf health, the approach offers an economically sustainable and environmentally friendly alternative to traditional antibiotic treatments.

Overcoming Challenges in Research

Conducting research on Cryptosporidium presented unique challenges. May faced the highly contagious nature of the parasite, requiring strict biosecurity protocols to prevent cross-contamination. The intensive workload of caring for calves, faecal sampling, and monitoring data also tested her time management skills.

“Balancing the demands of fieldwork and research required meticulous planning and teamwork with farm staff and my lecturers,” May shared. Their support, combined with her determination, allowed her to successfully complete her project.

Recognition and Future Impact

Winning the BSAS Undergraduate Thesis of the Year Award is a momentous achievement for May. Reflecting on this recognition, she said:

"It feels incredible to have my hard work recognised at this level. This award not only validates my research but also underscores the importance of sustainable livestock management solutions.”

May’s research aligns closely with current industry priorities, including the push to reduce antibiotic use and improve animal welfare. Her findings could inspire practical protocols for farmers, contributing to healthier calves and reduced economic losses.

Looking Ahead: May’s Vision for Animal Science

May plans to continue her research journey, focusing on animal microbiology and sustainable livestock health. Her aspirations include developing microbiome-based therapies like probiotics and prebiotics to improve livestock welfare while reducing environmental impacts.

“The field of animal science is evolving with advancements in sustainability, precision farming, and alternative proteins,” May observed. She aims to play a role in driving these innovations forward.
