Resumo: | This study evaluated the effects of adding an acidifying agent based on phosphoric acid (A ), a yeast extract from a specific strain (S accharomyces cerevisiae ) (Y ) and the combination of these two additives in food for adult cats. A test was conducted with 24 animals (mean 3.5 years old), mixed breed, weighing 3.72 ± 0.74 kg, kept in individual metabolic cages and distributed in a completely randomized design with a 2 × 2 factorial design (with or without A 0.6% of dry matter, with or without Y 1.5% of dry matter) totalling four treatments and six replicates of each condition. The experimental period was 15 days. The A or the Y reduced (P < 0.01) the dry matter intake, but the effect was not observed when they were associated. The association improved (P < 0.05) the digestibility of dry matter and ashes. The A reduced urine pH (P = 0.05) regardless of the presence of the Y . There was no effect (P > 0.09) on other parameters evaluated. Results of this study show that the isolated use of 0.6% A or 1.5% Y in diets for cats is not recommended. However, the association of these two additives was beneficial in increasing nutrient digestibility. |
