摘要
Growth performance, organ biometrics, bone characteristics, and intestinal morphometry were evaluated in broilers fed a diet containing orange (Citrus sinensis L.) essential oil. A completely randomized design was used, with five treatments with orange essential oil (0, 100, 200, 300, and 400 mg kg−1 diet) and six replications with 20 birds per experimental unit. In the pre-starter phase, feed intake and weight gain of all birds linearly increased, while feed conversion decreased with the addition of orange essential oil in the feed. At day 21, bone density (Seedor Index) and body weight were higher in the birds that received the maximum level of essential oil (400 mg kg−1) compared with those not treated with essential oil. The observed effects resulted from the better functioning of the physiological mechanisms of digestion and absorption of nutrients, characterized by the increase in villus height. Glycemia and weights of gastrointestinal tract organs of broilers at 21 days of age were not influenced by the evaluated essential oil. The results show that the addition of phytogenic additives to the diet does not cause any physiological impairment in birds.

在饲喂含橙（Citrus sinensis L.）精油的日粮中，对肉鸡的生长性能，器官生物特征，骨骼特征和肠道形态进行了评估。使用了完全随机的设计，用橙色精油（0、100、200、300和400 mg kg-1饮食）进行了五次处理，每实验单位有20只鸡，进行了六次重复。在启动前阶段，所有家禽的采食量和增重呈线性增加，而饲料中添加橙色精油则导致饲料转化率下降。在第21天，接受最大量精油（400 mg kg-1）的家禽的骨密度（Seedor指数）和体重高于未用精油处理的家禽。观察到的效果是由于营养物质的消化和吸收的生理机制更好地发挥了作用，其特征是绒毛高度增加。所评估的精油不影响21天龄肉鸡的血糖和胃肠道器官重量。结果表明，在饮食中添加植物性添加剂不会对禽类造成任何生理损害。
