Abstract:

Dental chews are recommended by veterinary dentists1 as home dental care to help maintain teeth clean. Safety and digestibility of these chews is, however, a major concern. In vitro digestibility of the following 6 dental chews was investigated in an independent lab: Veggiedent� FR3SH??? (Virbac), Greenies??? Fresh (Mars), Oravet??? (Merial), Dentastix??? (Mars), Prozym� sticks (Ceva) and Hill's� Prescription Diet� Dental Care Chews (Hill???s). The humidity level, protein content (Kjeldahl method), in vitro pepsic digestibility (sample heated for 48 hours at 40�C in a solution of pepsin hydrochloride2) and ileal digestibility as described by Boisen et al.3 (first incubation with a pepsin solution, pH2 for 6h to mimic gastric digestion and second with a pancreatin solution, pH 6.8 for 18h to mimic small intestinal digestion) were evaluated. Results are expressed as the % of nitrogen content (protein) dissolved (for pepsic digestibility) and as the % of dry matter dissolved (ileal digestibility). The humidity level ranged between 9.8% and 16.1% with a median of 13.5% and the protein content ranged between 6.5% and 43.1% of crude matter with a median of 15.55%. The results for pepsic and ileal digestibility were respectively of 100% and 100% for Veggiedent� FR3SH???; 96.5% and 91.8% for Greenies???, 100% and 98% for Oravet???, 96% and 100% for Dentastix???, 90.5% and 88.7% for Prozym� sticks and 97.2% and 100% for Hill's� Prescription Diet� dental care chews. Veggiedent� FR3SH??? is therefore totally digestible, as assessed by in vitro reference methods.
