Homemade cat food diets low on nutrientsMay 8, 2019Most homemade cat food recipes are unlikely to provide essential nutrients and some may even contain potentially toxic ingredients. Those are the results of a study by researchers at the University of California (UC), Davis who looked at 114 recipes from online sources and books written by non-veterinarians and veterinarians. While recipes authored by veterinarians had fewer deficiencies, the study found they were still lacking nutrients. Of the all the recipes studied, 40 percent did not provide feeding instructions and the rest lacked detail or were unclear. "Only 94 recipes provided enough information for computer nutritional analysis and of those, none of them provided all the essential nutrients to meet the National Research Council's (NRC's) recommended allowances for adult cats," says lead author, Jennifer Larsen, UC Davis School of Veterinary Medicine veterinary nutritionist. In addition, the study found many of the homemade cat food was lacking concentrations of three or more nutrients, with some missing up to 19 essential nutrients. Further, many recipes provided less than 50 percent of the recommend allowances of several essential nutrients, including choline, iron, zinc, thiamin, vitamin E, and manganese. The study revealed seven percent of the recipes included ingredients that are potentially toxic …

Study finds only low levels of methylmercury in dog foodApril 25, 2019A study by the University of California (UC), Davis on levels of methylmercury in samplings of commercial dog food has found low concentrations in the majority of the tested brands. Only three of the 24 types of dog food tested positive for low concentrations of total mercury, and only one contained detectable methylmercury. "The concentrations detected are unlikely to pose a risk to healthy adult dogs," says lead author, Rae Sires, a nutrition resident at UC, Davis's Veterinary Medical Teaching Hospital. "These results should be reassuring to dog owners." Other studies have measured total mercury in dog food, but this is the first time testing for methylmercury has been done. As methylmercury is present in aquatic species, researchers evaluated dog food containing fish, as well as fish-free foods. They found two of the three positive samples among the non-fish diets, which suggests common sources of mercury in pet foods. "We need more data to determine where the total mercury detected in dog foods is coming from, but our study doesn't support avoiding fish or salmon-based diets," Sires says.
UC Davis study applies human cancer differentiation analysis to dogsOctober 4, 2018The University of California, Davis, School of Veterinary Medicine (UCDSVM) is conducting a clinical trial to study the potential application for canine cancer screening using cancer differentiation analysis (CDA) liquid biopsy technology from Anpac Bio-Medical Science Co. Studying at least 186 dogs in a blinded clinical trial, Anpac Bio and UCDSVM are investigating CDA's ability to identify cancer in blood samples from dogs confirmed with sarcomas or carcinomas versus healthy control blood samples from dogs of similar age and breed. Following the initial screening, UCDVSM will then test if CDA levels also correlate to treatment response (i.e. if the dogs' cells are responding to cancer treatment such as surgery or radiation) and monitor remission/potential recurrence. "Dogs are just like people; the sooner we identify disease, the better chance we have in treating and curing it," said John Reddington, DVM, PhD, Anpac Bio's chief advisor for veterinary and comparative research. "Unfortunately, dogs can't tell us when they don't feel well, so, we often catch diseases like cancer late stage. [Anpac Bio's] cancer differentiation analysis liquid biopsy technology has proven to be very useful in detecting over 20 human cancer types with just a single …
