PALATABILITY RESEARCH REVEALS SURPRISING KIBBLE SIZE DISCOVERIES
For pet owners and industry professionals alike, it stands to reason that small dogs would prefer smaller- sized kibbles and large breeds larger-sized kibbles. This common belief has also influenced how dog food is produced and marketed to small, mid-sized and large dogs, with a general correlation between dog food kibble size and the breed size the dog food brand is targeting.
Experimental Design and Testing Protocol
- type and lot of meal (corn and chicken meal- based diet)
- amount of fat
- AFB palatant and amount on each kibble
- moisture content (not significantly different)
- bulk density for each kibble
- Texture analysis using three different types of probes to simulate dog chewing
- Electronic nose and tongue testing to determine degree of difference between kibble size in terms of flavor and aroma
The research showed that kibble size (diameter) in dry dog food does affect canine palatability, and the concentration of certain flavor components on the larger kibbles appeared to have driven the preference. Texture may also contribute to palatability, and further investigation could lead to product enhancements and innovations for dog food brands.
