Nutrition research background

The WALTHAM Centre for Pet Nutrition is recognised as a leading scientific authority within the field of pet nutrition and wellbeing.

Our researchers work across multiple disciplines linked with pet nutrition and health such as nutrient requirements for different pet lifestages and lifestyles, gastrointestinal health, energy requirements, immune function, skin and coat condition, oral health, feeding behaviour and clinical nutrition.

Publishing our research findings is extremely important at WALTHAM and since the 1960s we have published over 600 peer reviewed publications within the area of companion animal nutrition.

We pride ourselves on sharing key findings with the scientific and pet care communities, thereby providing a benefit to pets across the globe.

Oral Health background

The WALTHAM™ Oral Health research group has been working with leading veterinary dentists and academics across multiple scientific disciplines for over 25 years to investigate oral diseases in pets.

Oral diseases are a major problem for pets, with gum disease being one of the most widespread conditions in cats and dogs. If gum disease is not detected and remains untreated, irreversible damage to the gum occurs that results in the loss of teeth and significant pain to the pet.

To design oral care solutions that are effective for pets, we need to understand the specific mechanisms underlying oral diseases in cats and dogs. WALTHAM™ research underpins Mars Petcare oral care brands and key insights are published in peer-reviewed journals to highlight the importance of pet oral care so it may be used for the benefit of pets worldwide.

Since 2012, the WALTHAM Oral Health research group has published 12 peer-reviewed publications on gum disease in cats and dogs.

HAI Background

“The human-animal bond is a mutually beneficial and dynamic relationship between people and other animals that is influenced by behaviours that are essential to the health and well-being of both. This includes, but is not limited to, emotional, psychological, and physical interactions of people, other animals, and the environment.”
JAVMA, 205(11)L:1675,1998

For over 40 years WALTHAM has been driving industry-leading research that explores the special relationship between humans and companion animals, and has been instrumental in understanding the benefits this relationship brings to both people and pets. As part of this commitment, we work with leading scientific institutions to advance and share knowledge of the positive and lasting benefits of pet ownership on human and pet health.

Equine research background

The WALTHAM Equine Studies Group, which is headed by Professor Pat Harris, is dedicated to advancing the science of horse nutrition and provides the science underpinning the SPILLERS®, BUCKEYE® Nutrition and WINERGY® brands.


The WALTHAM Equine Studies Group partners with international collaborators to carry out research and gain knowledge in the areas of basic, as well as applied, equine nutrition and its role in the health, welfare, behaviour and performance of horses. We are committed to sharing the work with veterinarians, scientists and horse owners all around the world through journal papers, lectures and articles.

The WALTHAM Equine Studies group, together with the external researchers with whom they collaborate, has published extensively, for example over the last 10 years more than 200 scientific papers and articles in peer reviewed journals, textbooks, conference proceedings and educational manuals, in addition to numerous magazine and online articles.

Our pet welfare committee and researchers proactively work together to embrace the 3Rs of scientific research:

Replacement - we use alternatives to animals wherever possible: in vitro, in silico, human studies

Reduction - studies are designed to minimise the number of animals involved. Our statisticians play an essential role in this

Refinement - Animal welfare is a priority in all study designs and we make research an enriching experience for our pets
