The three-day Waltham International Nutritional Sciences Symposium concluded on September 18 in Cambridge, England, bringing together nearly 250 researchers to discuss advances in pet nutrition, petfood safety and weight management.

Participants were offered presentations on many subjects, including the effects of diet on intestinal bacteria, the potential for enhancing a cat's immune system by dietary supplements, the association between vitamin D and certain tumors in Labrador Retrievers and the problems that diets consisting of bones and raw foods can present for dogs. Two themed sessions were also offered, exploring the challenges in developing nutritional guidelines for pets and analyzing issues related to food safety in the petfood industry.
