Palatability Testing of Spray-Dried Animal Plasma-Infused Dog Foods and Treats
Source abstract
Abstract
The global pet food market is expanding rapidly, and there is a growing interest in sustainable, high-quality ingredients. Spray-dried animal plasma (SDAP), a protein-rich by-product with immune-boosting properties, is gaining attention as a potential additive. This study aimed to evaluate the palatability of dog products containing SDAP. Three types of canine products (dry food, wet food, and treats) with varying concentrations of SDAP (0%, 1%, 2%, and 4%) were tested. The study used a two-bowl preference method involving 20 dogs of different breeds, ages, and weights. Results indicated that a 2% SDAP concentration significantly increased the palatability of each dog food compared to control diets without SDAP, while higher concentrations (4%) negatively impacted it. For dry food and treats, the inclusion of 1% SDAP showed marginal effects on palatability. Statistical analyses revealed no significant correlation between the dogs’ sex or product type and their preference for SDAP-containing products (p > 0.05). This preliminary research supports the inclusion of SDAP in dog foods, particularly at optimal levels (2%), to enhance palatability and meet the nutritional needs of dogs while addressing sustainability in pet food production.
