Nutrient Digestibilities and Fecal Characteristics of Diets Including Brown Rice for Miniature Poodle

Abstract

In this experiment, two inclusion levels (15 and 30% of diets, as-fed basis) of brown rice (BR) were tested against a control diet with 0% BR (51% wheat flour of diet). Six female Miniature Poodles (8~9 months age, initial mean body weight of 3.5 kg) were assigned to treatments in replicated 3×3 Latin square design. Total tract digestibilities of DM, OM, CP, acid hydrolyzed fat and gross energy increased linearly (P<0.05), and observed digestible energy and metabolizable energy values also increased linearly (P<0.001 and P=0.007, respectively) with increasing BR inclusion levels. Wet and dry fecal output decreased linearly (P=0.001) with increasing BR inclusion levels in the diets. Linear (P<0.05) effects was observed in fecal score for dogs fed BR and fecal ammonia concentration increased linearly (P<0.05) 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<0.01). This study clearly demonstrates that BR improves nutrients digestibility and fecal characteristics of dog. 재료 및 방법본 실험에 공시된 암컷 푸들 (Miniature poodle) 강아지 (8~9개 월령, 시험개시 평균체중 3.5 ± 0.5 kg, 종료체중 3.7 ± 0.2 kg) 6마 리는 국립축산과학원의 반려동물영양 연구실에서 동물 보호법 및 국립축산과학원 동물실험윤리위원회에서 승인된 동물실험 방법을
