Abstract

This experiment was conducted to investigate the effect of star anise essential oil (SAO) supplementation in diets with different energy levels on growth performance, nutrient metabolic efficiency of broilers. One hundred and ninety-two Arbor Acres male broiler chicks at 28 days of age were divided into a 3 × 4 factorial arrangement design with three dietary energy levels (13.41, 12.82, 12.23 MJ/kg) and 4 levels of SAO supplementation (0, 200, 400, and 600 mg/kg of diet). Dietary supplementation with SAO increased (p < .05) apparent metabolic efficiency of CP, EE, GE, and all of the amino acids except Trp. Significant interactions were noted between energy level and SAO administration for metabolic efficiency of CP, all of the amino acids except Cys. Inclusion of SAO enhanced apparent nutrient metabolic efficiency of broilers in a dose-dependent manner, birds supplemented with 400 mg/kg of SAO in high-energy diets appeared to contain highest nutrient metabolic efficiency, moreover, the metabolic efficiency of nutrients in low-energy diets along with 200 or 400 mg/kg of SAO was similar with that in high-energy diets without SAO, which indicated that the SAO might ameliorate the negative effects of reduced dietary metabolic energy on nutrient utilization in broilers.

摘要

本实验旨在研究不同能量水平日粮中添加八角茴香油（SAO）对肉鸡生长性能和养分代谢效率的影响。将 192 只 28 日龄的 Arbor Acres 雄性肉鸡随机分为 3×4 因子设计，日粮能量水平（13.41、12.82、12.23 MJ/kg）和 4 个 SAO 补充水平（0、200、400 和 600 mg/kg 日粮）。日粮添加 SAO 提高了（p<0.05）CP、EE、GE 和除色氨酸（Trp）以外所有氨基酸的表观代谢效率。CP、除半胱氨酸（Cys）以外所有氨基酸的代谢效率在能量水平和 SAO 处理之间存在显著的互作。SAO 以剂量依赖的方式增强了肉鸡的表观养分代谢效率，在高能日粮中添加 400 mg/kg 的 SAO 的肉鸡表现出最高的养分代谢效率，此外，添加 200 或 400 mg/kg SAO 的低能日粮中的养分代谢效率与不添加 SAO 的高能日粮相似，这表明 SAO 可能减轻了日粮代谢能降低对肉鸡养分利用的负面影响。
