The objectives of these researches were to determine the effects of brown rice (BR) on food intake, digestion, energy value, and fecal characteristics. Two inclusion levels (15 and 30% of diets, as-fed basis) of BR were tested against a control diet with 0% BR (51% wheat flour of diet). Six female miniature Schnauzer (8∼9 month age, initial mean body weight 5.0±0.3kg) in Exp. 1 and six female Maltese (8∼9 month age, initial mean body weight 2.8±0.3kg) in Exp. 2 were assigned to treatments in replicated 3×3 Latin square design, respectively.
In experiment 1, total tract digestibilities of DM, OM, acid hydrolyzed fat and gross energy except CP increased linearly (P<0.01), and observed digestible energy and metabolizable energy values also increased linearly (P=0.001 and P=0.006, respectively) with increasing BR inclusion to the diets. Wet and dry fecal output decreased linearly (P<0.001, P=0.004) with increasing BR inclusion to the diets and BR 30% treatment reduced wet fecal output up to 21% of that of control. Linear (P<0.05) and quadratic (P<0.01) effects were observed in fecal score for dog fed BR and fecal ammonia concentration tended to increase linearly (P=0.07) in response to increasing BR inclusion level. It seems that the increase in fecal ammonia concentration may be partially related to the decrease in short-chain fatty acid concentration (P=0.001). This study clearly demonstrates that BR improves nutrients digestibility and fecal characteristics of dog.
In experiment 2 and 3, total tract digestibilities of DM, OM, acid hydrolyzed fat, CP and gross energy by dogs fed experimental diets responded quadratically (P<0.01 or <0.05) to BR inclusion levels. Similarly, quadratic responses (P<0.001, P=0.015) were observed for digestible energy and metabolizable energy values. Wet and dry fecal output also exhibited quadratic responses (P=0.006, P=0.014, respectively) without no differences between control and BR 30% diets. Linear (P=0.008) effect was observed in fecal score for dog fed BR and fecal ammonia concentration increased linearly (P=0.001) in response to increasing BR inclusion level. It seems that the increase in fecal ammonia concentration may be partially related to the decrease tendency (P=0.07) in short-chain fatty acid concentration. In this experiment, inclusion of BR to dog diet did not result in pronounced changes in the digestibility but in fecal score. Although inclusion of BR in diets showed profound positive effect on fecal score, it is confounded by the high inclusion level of poultry offal meal.
In experiment 4, Chungkukjang powders enchanceed palatability of food and digestible energy intake. It might show the possibility of Chungkukjang powders as a material of dog food. In the other experiments, Red ginseng marc, unhulled barley, L. reuteri, handmade feed and etc. were used to determine the possibility as a material of dog foods.
