Descrição: dc.descriptionLarge dog breeds commonly produce unformed faeces. The present study hypothesised that foods for large dog breeds require higher starch gelatinisation (SG) to reduce organic matter flow to colon. Fifteen Rottweilers (Ro; 49.4 ± 6.12 kg), 18 Beagles (Be; 12.13 ± 1.75 kg) and 20 Shih-Tzus (ST; 4.62 ± 1.15 kg) were fed one of three diets, all based on the same sorghum formulation, processed to obtain three levels of SG: SG90 (91.8% SG), SG50 (50.7% SG) and SG30 (27.4% SG). Foods were provided for 23 days, and the coefficient of total tract apparent digestibility (CTTAD) of nutrients, faecal production and fermentation products, Na, K and Cl apparent absorption and gastrointestinal transit time (GTT) were evaluated. Results were submitted to analysis of variance considering SG, breed and their interactions, and means compared by the Tukey test (p < 0.05). All dogs promptly ate the foods. Faeces scores were lower for Ro than for Be and ST, and lower for SG30 than SG90 (p < 0.05). Faeces pH was higher, and total short-chain fatty acids were lower for SG90 than for SG50 and SG30 (p < 0.01), regardless of breed. No diet effect was observed for GTT (p > 0.05), but it was lower for Ro (41.7 ± 6.2 h) than for ST (48.7 ± 8.6 h). The CTTAD of nutrients was lower for SG30, intermediary for SG50 and higher for SG90 (p < 0.05), and among breeds CTTAD was higher for Be than ST and Ro (p < 0.05), which did not differ from each other, except for crude protein CTTAD which was lower for Ro (p < 0.05). The apparent absorption of Na and K was higher for the SG90 treatment, and for Be in comparison with Ro and ST (p < 0.05). Food SG had a remarkable influence on Ro faeces formation and on the CTTAD in all breeds. Greater fermentation in the colon and lower protein CTTAD may be involved in Ro unformed faeces formation.-
