In this study, we analyzed the effects of including açaí kernel, in the experimental diets fed to horses on the intake and digestibility of their nutrient and the resultant effects on the behavior of horses. The experiments were conducted in Federal Rural University of Amazonia. Five mares with no defined breeds, were allocated to five treatments (the replacement of Mombaça grass (Megathyrsus maximus) with crushed açaí kernel at 0, 18.75, 37.50, 56.25, and 75% levels of dry matter), in a 5 × 5 Latin square design. The animals were housed in covered stalls with concrete floors, equipped with individual troughs and drinkers, and fed 80% roughage and 20% concentrate. The inclusion of açaí kernel altered the intake and digestibility of a few nutritional components and the feeding behavior of mares. Increasing levels of the substitution of Mombaça grass with crushed açaí kernel in the experimental diets increased the nutrient intake and digestibility of neutral detergent fiber, total carbohydrates, and non-fibrous carbohydrates (P < 0.05) while reducing the time spent on feeding by the animals. Crushed açaí kernel can, therefore, be included as a substitute for Mombaça grass at up to 37.5% in equine diets.
在这项研究中，我们分析了在实验马饲料中添加阿萨伊果核对马营养物质摄入量和消化率的影响，以及对马行为的影响。实验在亚马逊联邦农村大学进行。将五匹无特定品种的母马分为五组（用粉碎的阿萨伊果核替代 Mombaça 草，替代水平分别为干物质的 0%、18.75%、37.50%、56.25%和 75%），采用 5×5 拉丁方设计。动物被安置在带有混凝土地板的有盖畜栏中，配备有单独的食槽和饮水器，喂食 80%粗饲料和 20%浓缩饲料。阿萨伊果核的添加改变了一些营养成分的摄入量和消化率，以及母马的喂养行为。实验饲料中用粉碎的阿萨伊果核替代 Mombaça 草的水平增加，会增加中性洗涤纤维、总碳水化合物和非纤维碳水化合物的养分摄入量和消化率（P<0.05），同时减少动物的采食时间。因此，粉碎的阿萨伊果核可以作为马饲料中 Mombaça 草的替代品，替代比例可达 37.5%。
