Abstract
CJ Cheiljedang Corporation, Seoul 100-749, KoreaABSTRACTThe objectives of this research were to determine the effects of brown rice(BR) on food intake, digestion, energy value, and fecal characteristics. Three replacement levels which BR replaced 0, 15 and 30% of wheat flour were tested. Six female Miniature Schnauzer(8~9 month age, initial mean body weight 5.0±0.3kg) were assigned to treatments in replicated 3×3 Latin square design. 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 replacement level. 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. Quadratic(P<0.01) effects was observed in fecal score for dog fed BR and fecal ammonia concentration tended to increase linearly(P=0.07) in response to increasing BR replacement 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.(Key words : Brown rice, Fecal characteristics, Digestibility, Dog diets)
